G3 non-stock AOSP Lollipop kernels mostly do not include the needed FM kernel driver.

When I ask on some kernel thread for FM to be enabled I usually get no useful response, so I think it's better if several kernel users ask.

And it's hard to find time to engage in many thread conversations; I'd rather be coding instead.

If they complain Spirit is a "commercial app", please point out the Free Open Source version of Spirit2.


I'll see if I can submit the simple 2 line kernel config file "patches" and get anyone to accept it.

thanks for your reply.
i will test with an stock kernel.

Yes, there is hope, but you may have to wait until I buy a D855 and make it officially supported. Work will still be required, even my HTC One M7 is giving me trouble with the Lollipop GPE vs the new Spirit2 audio architecture for Lollipop. This might even be related to G3 problems.

But... I am going to add some options to Spirit2 that might help fix G3 sooner.

Your request, several Lollipop failure reports, and some promising sales statistics I think MAY have pushed me over the edge to getting one.

I've cursed my G2 Sprint variant many times and have been hesitant to deal with LG again, but at least the G3 moves back to Qualcomm FM/combo chips, which are easier to support than Broadcom...

D855 seems to be available on EBay for $400 - $500 now ?

Any news about this? I would be very interested in purchasing spirit if it supports the G3. Thanks!

hello,

spirit 2015_02_12_beta of rom resurrection remix 5.3.4 (n7000)

Always this problem of complete freeze of the telephone having started spirit fm 2.

The application launches, then nothing more everything is blocked (no sound, the buttons of the radio do not react)

I was able to sent a report of error during the crash, I hope that this one can help you to make adjustment.


Thank you for your work.

Work is underway. :)

Some details on the G3 specific thread: http://forum.xda-developers.com/apps/spirit-fm/support-lg-g3-cyanogenmod-12-t3027103#post58893015

Summary: I am submitting the needed patches to CM.

I might post a kernel or unofficial ROM before the patches go through.

I am also "on the cusp" of a non-analog-mode solution for horrible audio due to microphone pre-processing on several Qualcomm based devices.

Thanks for your report. :)

A new problem that didn't happen on previous releases ?

I will likely release a new beta within 24 hours.

Spirit FM in Sony Xperia ZL (6503)

Good day,

I need help, which version would be running on the Sony Xperia ZL (6503)?

I am using the CM12.

Hi Mike,

Today I've flashed CM12 on my Xperia T and hoped that Spirit would work on it - so I bought it via the play store (fm.a2d.s2) to try it, the app is working - as in not freezing / crashing etc - however it's not useable as the signal is very poor,
whilst going through the threads on XDA (might have done that prior to purchasing - but that's another discussion) I found that I might require Spirit Transmit instead?

Any guidance / support would be highly appreciated.

help - P500

I'm new to custom roms and spirit and use to regular listen to broadcast radio when I was on stock Gingerbread

I upgraded my LG P500 to kitkat using cm11 [v11] and used the spirit settings described here except they don't work :crying:

I simply get Error: No FM accessible SU:2 Fm:BC2 Su:1 Bt:0 Ht:0 Mo:BCU

Any ideas ?

Note I had CM11 v12 but downgraded to v11 as the Spirit settings described in the link above don't exist in the Spirit that comes with CM v12

Spirit 2 for kitkat on HTC One S

Spirit 2 works, but after about 15 min, the audio cuts off and I have to close and restart the app to get audio back. Any thoughts?

Thanks!

Incidently you one give superuser permission for 15 min only, better open supersu app then go to settings then click the # icon there - it turns green if you grant permission ..because by default it only gives permission for 15 only....

Good day,

I am using the CM12.

Sorry for my delay...

As Spirit has passed it's 4th birthday, I have decided to spend more time in seclusion to develop, and less time here on XDA and with email. I have made very good progress on Spirit2 the last few weeks, without undue distress to my sanity or family life. :)

For Lollipop+ ROMs, Spirit2 is the only viable & supportable option. I have an experimental Spirit1 that works on some Android 5 ROMs/devices, but only if SELinux is disabled, which I can not recommend.

Spirit2 should work OK on Xperia ZL if the kernel contains the FM driver needed. Some of the FXP/CM12 ROMs have kernels with FM disabled at this time, but I am working to get that fixed.

There is a chance you might need to manually set an Antenna option. If the "Internal" setting works, then your Sony is able to transmit too, with Spirit Transmit... :)

One of the other issues with Sony's running CM12 is that some have a horrible sound, due to microphone pre-processing that I am looking for some better methods to deal with. One option here is to remove a system library file (with mic implications). Another is the use of an experimental analog audio mode in the latest Spirit2 beta updates, including today's: Feb 21: 20150221.

whilst going through the threads on XDA (might have done that prior to purchasing - but that's another discussion) I found that I might require Spirit Transmit instead?

Sorry for my delay. See post 8946 above for an explanation... :)

No, Spirit Transmit is only needed if you want to SEND or TRANSMIT FM signals/audio to some other FM radio or phone with an FM radio function. And Spirit2 has a hidden, limited transmit mode to test with: Enter "48" as if it is a frequency to enable, and restart Spirit2. Enter "49" the same way to disable and return to FM receive mode.

BUT, there is a link between Transmit capability and an "Internal Antenna" setting that is needed on a few Sony devices that Spirit2 does not yet recognize as needing that setting. The link is that if "Internal Antenna" works, then transmit does also.

Spirit1 has this setting to set manually, but Spirit2 will not until probably the next beta release.


BUT, you may be having the "no Qualcomm V4L FM driver in the kernel" problem that is happening on many Sony's. At present, Spirit2 does not report this problem properly, and instead seems to start and work, but does not.

I have submitted a patch to CM12 for this issue on my Xperia Z1, but haven't gotten back to (I think) doing the patch for other Sony's that the CM person I dealt with requested. I have a self built kernel for my Z1 that works, and I may build some kernels for the other devices in the next few days.

I think that changing frequency, or just re-setting the existing preset restores audio without having to restart Spirit2.

I think that the new 20150221 Feb 21 beta release of Spirit2 finally fixes this issue on Qualcomm FM chips. Customers can sign up for beta releases with the instructions here: http://forum.xda-developers.com/showpost.php?p=57079402&postcount=795

I think that the fancy power management was shutting down the FM audio because it "thought" it wasn't being used.

Previously I had sometimes useful code to "kick" the chip when silence was detected, but the better solution is just to kick it every 10 minutes, LOL.

Thanks.:)

It was a Qualcomm FM chip specific power management issue as I posted above.

The latest Spirit2 releases generally only need SU once when FM is started. Unless FM is powered off, Spirit can run for days without needing SU again, even while audio is paused, though starting any media player app will kick FM off.

Spirit News Feb 21, 2015: The "Spirit FM Radio" project is now over 4 years old ! :)

Here is the thread where it was born: http://forum.xda-developers.com/showthread.php?t=947581 and my 1st post #6 on that thread: http://forum.xda-developers.com/showpost.php?p=11279004&postcount=6

I am happy to say that after 4 years I am pretty happy with the outcome, though my income is a fraction of what "normal" jobs in this field pay, and I have no cache of Google, CM Ine, or any other stock options to see me retiring anytime soon.

How far has Spirit come, and what is next ?

First, sometimes things seem to take forever, but "1st things 1st": I prefer to concentrate on minimizing bugs and taking care of the millions of "under the cover" issues before adding "eye candy" and non-essential features on top of an unstable base.

Now that I am reasonably happy with the stability of Spirit2, I have been able to add many new settings and features. Most of these finally re-duplicate Spirit1 features, but of course on top of the much better designed Spirit2 which is the clear "way forward".

Second, I'm really happy with the "new, improved" Analog mode in the Feb 21 Spirit2 beta. Spirit2 has re-entered the analog domain that Spirit1 and most stock FM apps were based on. Why, and what does this mean ?

Spirit2 was designed with "Digital Audio" as the method to move audio from the FM chip to our ears, instead of the analog (or not fully digital) audio architecture that pretty much every other FM app uses, even now in 2015.

This makes FM audio act like media player audio, instead of the "special" and restricted form of FM audio that FM was originally designed into smart-phones with. FM was a "tacked on" afterthought and had a special & external position in the audio chain. I believe this is a direct result of the fact that FM radio goes against the business interests of Google (as well as Apple and US carriers.)

FM audio could not (and usually still cannot using other FM apps) be equalized, bass-boosted, re-verbed and otherwise processed. It usually can not be send to Bluetooth headsets, nor recorded or visualized.

Spirit2's method of FM digital audio means you can equalize and process it, send it to Bluetooth devices, record it and visualize it. I don't think there is ANY other FM app that provides all of these features together (to say nothing of all the media button/AVRCP, notification shade, lockscreen, homescreen widget features and many settings, present now or soon.)

Spirit2's digital audio architecture was back-ported to Spirit1, but despite relative stability and a full year of fixes, was never made fully supported or default. That job went to Spirit2, which still had to compete for development time with Spirit1 throughout 2014.

But with the upsides of digital audio (including some invisible to most of you, but that make my work a bit easier), come downsides, and some of these are reasons to re-implement an analog mode in Spirit2:

- Digital audio mode does not work well on some ROMs/devices. Most of my testing is with CM11/12, and these tend to work well with Spirit, ut there are always some ROMs/devices that have issues.

Currently, many Sony (and some other) devices, especially on Lollipop, have horrible audio, due to microphone based pre-processing that kills audio quality for non-speech and non-microphone purposes. I am examining solutions for this, and analog audio is a quick fix/workaround.

- Some semi-popular devices (like GS3 mini) are supported with Spirit1 analog audio mode, but not with digital mode, nor with Spirit2 at all when it had only digital mode. Digital audio mode is impossible with most older devices, and even where possible would require too much investment of time and money to be worth it.

In the case of the GS3 mini (and some others), Spirit2 has tuner code for the FM chip, but no audio code. The analog mode allows me to add experimental audio methods for such phones from the Spirit1 code.

The Spirit2 Free and Open source version (which has 90% of the code of the full Spirit2) is hoped to benefit from this. I am creating an audio plugin design, like the existing FM tuner chip plugin design, that will allow others to add support for phones that I can't officially support for lack of time, etc. Plugins for analog mode should be easier than for digital.

- Analog vs Digital "purity": In some cases, analog audio may sound better to some people. Xperia Z2 & Z3+ especially has a disappointing architecture here, for 2014-2015 devices. It, as well as the EXTREMELY popular GS3/GS2/GS1/Note2/Note1 devices (70% of Spirit sales) provide only analog outputs from the FM chip, AFTER processing the audio digitally, as ALL smartphone FM chips have done since the dawn of Android.

So on those devices, Spirit2 routes the analog audio from the FM chip to "ADC's" (analog to digital converters) on the audio chip. Then the digital audio is processed digitally, and usually (non-Bluetooth) sent out to DACs to convert the digital back to analog for wired headsets of the phone speaker. The result is one additional D-> A-> D pair of conversions. Each conversion loses some audio quality. Add them all up, and you may be surprised:

Singer/instrument professional analog microphones -> professional ADCs -> professional processing -> digital CD -> analog FM transmitter (at least 1 conversion) -> analog FM receiver -> FM chip ADCs -> FM chip processing -> FM chip analog outout -> audio chip ADCs -> Android processing -> audio chip DACs -> analog processing -> wired headset or speaker. Wow, long chain, and that's a minimum. Adding another pair of conversions is bad for audio quality, especially in the later and non-professional stages.

Note that many modern devices do not support a TRUE analog mode and I describe them as "non-digital", meaning "Not the digital audio mode in Spirit2". But they are digital underneath, with all the advantages of digital, but without the downside of having to first convert analog to digital and thus adding 2 new conversions to the chain.

The fully digital devices supported by Spirit2 are: HTC One M7, One M8 (and all other Qualcomm FM devices, including Xperia Z/Z1 class, MotoG and LG G3), LG G2.

The analog conversion devices are Xperia Z2/Z3+ and all Spirit2 supported Samsung flagships: GS1/GS2/GS3 and Note1/Note2.


- What about reduced CPU and power consumption ?

No, analog audio mode provides no substantial savings at present, but this can be improved somewhat.

Some fellow tester reported it does work on CM11, though.

Send me a debug log with Menu->EMail Logs.
I would, but it seems the free version doesn't allow that. :(

Is there any way I can help getting this running on CM12 on the Saga?

    Compatibility

    Edit August 18, 2015: I haven't updated this list since June 29, 2013 largely because FM has been dying on Android devices. Samsung hasn't supported FM on flagships since the International GS3 GT-I9300 and Note2 GT-N7100 and never supported FM on US flagships except for some rare Sprint devices.

    If there is no stock working FM app on your device, chances are close to zero these days, especially on Samsungs.

    The only additions I have made in over 2 years are: Sony Xperia Z2/Z3 or compatible, rooted LG G2 International or Sprint, and rooted devices with Qualcomm FM/combo and audio chips, such as the HTC One M8, Xperia Z1 and similar, and some lesser known devices.

    Next Gen: Spirit2

    After almost 2 years, Spirit FM (Spirit1 or version 1) is "mature". Among over 10,000 paid customers, many have been happy to run Spirit on 2-4 generations of phones.
    From HTC Legends, Desires and Nexus1's running Android 2.1 Eclair, to OneX, Galaxy S, S2, and now S3 & Note2 running Android 4.2 Jellybean.

    Spirit1 was not designed much, it was rapidly built using an open source app as it's base. This enabled a quick implementation on many phones, ROMs, etc.
    A lot of quick hacks has accumulated, and now it's difficult to change or cleanup many sections of code without creating bugs on some phone and ROM combinations.

    It's time to start fresh and design and build Spirit2 "properly".
    I'll create a system to enable new settings/options in a few minutes, instead of an hour or more, editing 5 or 6 different files.
    The code will be much cleaner, efficient and bug free when it doesn't have to support 7 different versions of Android, 200 different phones and 10 different FM APIs.


    Spirit1 Future

    Spirit1 will not disappear. Support will continue, but I can't guarantee I'll be able to make it work on old (3-4 year) phones running Android 4.2 JellyBean, for example.
    No major new functions will likely be added to Spirit1. For example, FM record may remain an experimental test option, but will not be supported.

    I will continue to make and release some minor bug and compatibility fixes; timing & extent to be determined. My focus will be on Spirit2, the future.
    I hope those disappointed will eventually appreciate my decision to focus on the future when they get a new device.

    I expect to cease sales of Spirit1 at some time; maybe in months or maybe years. At present, Google doesn't provide a good way to do this, and still allow
    existing customers to re-download. AFAICT we can only set the price to high values, such as $99.99 or $249. If you ever see such a price on Spirit1 Light,
    or Light & Unlocked, don't be appalled. It just means I wish to stop new sales while keeping existing customers happy.

    In the short term, Spirit1 might even become a testing ground for Spirit2. Before a device is officially supported by Spirit2, it may be enabled on Spirit1.
    Sometimes I get several reports that a new phone works OK. Then after some time, major problems become evident that make me regret calling the device supported,
    especially for rarer devices.


    Spirit2 Plans

    Plans are always subject to change. Gotta be nimble. :)

    Spirit2 will be available on Google Play around January, 2013. Beta versions will be available earlier, linked on a new XDA thread.
    No Light version is planned, but a free version may be. Price should be the same as Spirit1 Unlocked.

    Existing Spirit1 Unlocked customers can upgrade at no cost to Spirit2. Spirit2 isn't about making you pay twice.
    But if you feel generous and appreciative of my support over the last few years, I'd be happy if you made a 2nd purchase.
    Or as some appreciative users have, a 3rd, via Light or an additional tip/donation. :)

    The upgrade path from Light to Spirit1 Unlocked, or to Spirit2, or from Unlocked to Spirit2 is the same. I cancel your original order, even 2 years later, and you get
    a full refund. Then you simply buy the new version. You can email me for special needs, such as needing 2 versions for different phones.
    I cancel any order at any time on request anyway, so this is nothing new.

    Spirit2 will focus on a smaller number of popular phones among custom ROM developers and users. I will only support phones that I own for testing, and those with
    very similar architectures. The 80/20 rule applies here, and focusing on 20% of the phones, for 80% coverage just makes sense.

    If you want to run Spirit2, I recommend popular high end devices, mostly from Samsung and HTC. I'll be happy to make exceptions for other OEMs with popular higher end
    phones, or phones with a similar architecture. For example, LG Optimus G and some Motorola devices have the same S3/S4/+ Qualcomm FM/audio architecture as HTC OneX LTE.


    Spirit2 Design

    Spirit2 design started November, 2012, after a 12 month delay from original plans. :)

    Spirit2 will support digital audio features, such as FM recording, Bluetooth, VU meters and who knows what, possibly including visualizations and audio analysis.
    Phones that are not capable of digital audio features likely won't be supported. Thankfully, the wildly popular GS2 GT-i9100 is now proven to support digital FM audio.

    Unchanged from my original 2011 plan, Spirit will use and support the ST-Ericsson proposed Android FM API, hereafter referred to as "Android FM API", despite it's
    mere "proposed" status. The Android FM API was first proposed over 2 years ago now, and seems to slowly be making it's way into AOSP. It's slow progress,
    and uncertain future, has disappointed me. I hope that Spirit2 will help this FM API gain support from
    phone and FM chip OEMs, as well as other 3rd party app developers.

    Many Sony 2012 phones support this API already, on devices based on ST-Ericsson, Broadcom and Qualcomm FM chips at least. So stock, unrooted Sony devices should be
    well supported, in theory at least. I'm not committing to official Sony support at this time however.
    This API is similar to other "OEM Proprietary FM APIa" that don't need SU/root. But it's not proprietary, it's openly documented & uses open source code.

    Other "OEM Proprietary" APIs will likely not be supported. Spirit2 will retain a focus on custom AOSP type ROMs that are incapable of running stock FM apps.
    Support for different FM chips will be via plugins, exactly as specified for use with the Android FM API.

    Unless and until phone or chip OEMs supply suitable FM chip plugins, Spirit2 will provide them. Sony has at least 3 plugins, but it's not clear if Sony can or would
    allow their free re-distribution for other devices.

    Third party developers will be able to write apps using the open, rich & documented Android FM API.
    They will be able to run as standalone apps, widgets, etc. without Spirit2, on devices such as the Sony's that support this API (or a slight derivative).

    On devices that do not support this API natively, 3rd party apps will be able to call compatible functions in the bottom-half, service portion of Spirit2.
    They won't have to bother with tedious, boring stuff such as configuration, as the top-half, app/GUI portion of Spirit2 can handle that.
    Or they could provide their own configuration mechanisms and do anything that Spirit2 does.

    I hope that custom ROMs will be built using the Android FM API AOSP code, and support FM natively within their audio libraries and frameworks.
    But I can't count on this anytime soon, so Spirit2 will do it's best to emulate functionality that is ideally done in the internals of a ROM.
    This is the current situation with Spirit1 on many custom ROMs and it requires LOTS of effort and can never be perfect.

    "FM Chip control" is just one part of the Android FM API. The other major component is audio routing and control. Audio has been the major challenge of Spirit1.
    The FM chip/API code has changed very little during 2012.

    A device that fully supports the Android FM API makes audio issues quite simple. The app can simply start or stop the audio with easy functions. Complexities like
    volume control, headset cable media buttons, lockscreen controls, and possibly A2DP Bluetooth support can be taken care of by the framework of the ROM.
    Even FM recording should be simple, on devices that support it. Spirit1 supports a simple FM record function, but it only works on devices like GS3 at present.

    But Spirit2 will remain a more or less normal SU/root app, as Spirit1 is. I'm one person & don't have the resources to get involved in building kernels, libraries,
    frameworks and ROMs. So Spirit2 will have components that replicate, as best it can, a proper system service for handling FM and FM related audio.

    It seems to make sense to design & build a plugin mechanism for handling FM audio, similar in concept to the FM chip plugin for the Android FM API.
    The Android FM API chip plugin, a library file such as libfmradio.cg2900.so, is oriented to code at the C/C++/JNI layer of Android/Java.
    The Spirit2 audio system plugin is more likely to be done at the Java level, as there are many Android Java APIs that are required or useful.

    Hypothetically, Spirit2 could run even on officially unsupported phones, if someone has or writes an FM plugin and an audio plugin.
    Many FM chips could be supported, with at least basic features, by a single generic V4L FM plugin. A simple generic audio plugin could be created
    that would rely on configurable "reflected" Java APIs or shell scripts etc. The "real world" however, is messier than this might imply.

    Some portions of Spirit2 will be open sourced. Details to be determined.


    EDIT: Which phones/architectures will Spirit2 support ?

    Tentative, but:

    Galaxy S3/Note2
    Galaxy S2/Note
    OneX International
    OneS/X LTE, Evo 4G LTE & similar S3/S4/+ + WCN3660 + WCD9310. Might include Optimus G, Motorola.
    Any Nexus capable of FM. Nexus 4 ? 10 ?
    Sony 2012's maybe, since they support this API when stock.
    I'm keeping an eye on popularity & compatibility of Motorola Razr I.

    Galaxy S GT-I9000 speaker damage risk:

    EDIT Feb 12, 2014: I still get occasional reports of speaker damage, about 1 every 3-4 months. Nothing can be done I'm afraid... :(

    EDIT May 20, 2013: One person has reported damage with digital audio mode. Virtually everything is different in this mode, so I can't imagine why it would happen. The only audio commonality is the analog outputs feeding into the inputs of the audio chip.

    March 23, 2013: See end of post for a potential digital audio solution. Digital audio is normally an Unlocked exclusive feature, but on Galaxy S it is available for Free users.
    There is a risk of speaker damage on Galaxy S GT-i9000 when running custom ICS or JB ROMs.

    If you've been running Spirit for at least 10-40 hours with no problem, your risk is minimal. I think this is hardware related and about 1-5 % are susceptible. I get about 1 report every 3 weeks now.

    Avoiding use of the speaker or keeping volume low does not help. Risk may increase when using USB cables to PCs or chargers or external amplifiers.

    If you are worried about Galaxy S speaker damage, then DO NOT use Spirit, unless on CM7 or a stock derived ROM. Use GB ROMs with proven safe FM, get a new phone, or just live without FM.

    Unless you are familar with ALSA programming, Ioctls and low level Linux/Android kernel stuff, as well as DC servos in amplifiers, please do not think you have useful technical advice to give about what I should study. I've spent at least 400 hours on this problem, with no analog solution.


    Have Damage ?:
    If you've had GalaxyS speaker damage, and are a BRAVE do it yourselfer, here are some Ebay links for speakers and instructions on replacing them: http://forum.xda-developers.com/showpost.php?p=23014977&postcount=2355 All responsibility for any problems doing this is yours.

    Ringer/Buzzer Speakers are available on Ebay new for $6 shipped, or $8 refurbished shipped from the US to the US.

    I'm very sorry for any problems. I had no idea this problem would happen or go on this long. It's rare that software causes hardware damage.

    If you're angry, or think my dev skills are sub-par, please refer me to the secret documents for FM audio via Galaxy S ALSA controls. There is none. I've read the code for various audio libraries, and the ALSA drivers, many times, and though the March 4th, 2012 attempt seemed a virtual duplicate of the CM7 audio lib, the problem continued.

    If you've been affected, please email me at [email protected] to report.

    Thanks, and sorry for any troubles.


    Hopeful Digital Audio Solution:

    Using digital audio mode likely reduces or eliminates the risk. As of March 23, 2013, it's too early to tell.

    EDIT May 20: One person has reported damage with digital audio mode. Virtually everything is different in this mode, so I can't imagine why it would happen. The only audio commonality is the analog outputs feeding into the inputs of the audio chip.

    On first Spirit startup, or after clearing app data, you are presented with a choice of "Digital" or "Danger". Choose "Digital". If running Unlocked, restart Spirit to enable Visualizations and a record button.

    You can also set Menu-> Settings-> Audio-> Method to "Digital Auto" or "Digital GS1", both near the end of the list.

    If you hear interrupted high frequency "chipmunk" sounds, rebooting may help, at least until the microphone is used (but phone calls OK ?).

    If a reboot doesn't help, you can disable Digital-> Stereo and do Pause / Play. Audio is now mono of course, so you might as well set Audio-> Output Mode (or Channels next release) to "Mono Force".

    More chipmunk info: http://forum.xda-developers.com/showpost.php?p=39383252&postcount=5696

    Battery consumption may be a bit higher using digital. Unlocked uses substantially more CPU & battery when visualization is on screen, and when equalizers, effects and Bluetooth are in use.

    I'm taking a MUCH needed break from Spirit and will restart work on Spirit2 in late October.


    After 2.7 years and over 9,000 hours spent developing, supporting and otherwise dealing with Spirit FM:

    - I need to draw a line in the sand here and take a week off to "detox" from the Internet.

    - Then I need a month for doing taxes and pressing family, household and personal tasks.

    - Then I need at least a few months to explore where Spirit is going with Spirit2 and/or some other FM app related stuff I'm considering.


    So,... given that I endeavour to be as honest and open as I can: I regret that going forward, I'm not going to be able to provide the high level of support
    I've been providing and been struggling to maintain.

    As always, if anyone has purchased Spirit and feel they haven't had sufficient enjoyment: I cancel any order at any time on request.

    For answers to most questions about Spirit, use the search feature on this XDA thread. If you can't find an answer, post, and hopefully some helpful person will answer,
    maybe even me occasionally. :) I previously answered every question on this thread, but I have to let that go now.

    I appreciate if anyone helps anyone else here, but ask that you be nice. I think it's probably better to ignore a poster than respond with an angry "Read the FAQ !".

    If Spirit doesn't work with default settings, maybe alternative settings will work. But this is the exception now. If it doesn't work by default, it probably won't.

    As time goes on, stock and custom ROMs will update/change and something may break in the FM access. I've hypothesized that for custom ROMs, within 3 months as many as 50%
    of ROMs will have a role in some problem with Spirit. If Spirit has 0 or just a few small updates in the next 3 months, I'll be interested to see the result.

    This breakage rate is largely the nature of the fast pace of change in ROMs, but change happens in stock ROMs too. The bluetooth stack has undergone major revisions in
    Android 4.2-4.3. I've dealt with that, and Android 4.3 related issues, so hopefully Spirit will run well on new or recent phones for a while.


    Since I'm looking at other "projects" in the Android FM app area, there's a reasonable chance that Spirit will continue to have related updates. But since I may
    (or may not) be concentrating on stock FM support, improvements may be restricted to stock support. The beta access for Spirit Unlocked and Light may be a way to deal with that.



    ----------------------------------------------------------------
    Sidebar:

    It's been a constant struggle to reverse engineer FM chip/API details as they change from chip to chip, phone to phone, OEM-OEM, Android version, API version, custom ROM, and more.

    Google isn't helping the cause any, nor are many of the phone OEMs, chip OEMs and carriers. Nobody else has been "crazy enough" to try what I'm doing with FM.

    Gee, even the top FM apps from Sony and Samsung don't do most of the digital audio features that Spirit can, even on an ancient GT-I9000 Galaxy S.

    But despite the work and crazy hours I put in, there are still some nasty & effectively unsolvable problems, like audio on Desire HD, a UI that needs serious improvement,
    and annoying things like 87.5 on startup with stock Broadcom API.

    The code for Spirit is a horrible mess, and deserves to be replaced with a (properly) designed Spirit2 or whatever.

    ----------------------------------------------------------------

    I'm not going to be monitoring my usual email address [email protected] as much, and not at all during any Internet "detox" week.

    This email will auto-respond that:

    - Purchase cancel requests (Only !) be sent to [email protected], or perhaps to the normal email with "CANCEL"
    spelled out in capitals in the subject. And be patient please, even Google can be glacially slow handling these.

    I may or may not respond to any emails or posts. Sorry, I kinda hate to become "that kind of dev", but this is essential for me, and for Spirit, at this time.

    I appreciate all the appreciation for Spirit, and feel satisfied with the 4.7 out of 5 rating that Spirit Unlocked has on Play, from thousands of people.

    I hate to see that rating drop because I can't provide the same level of support, but I guess that would be fair and should be expected. I'd be more likely to drop a rating if I was the
    customer and there was little or no support for some problem.


    ----------------------------------------------------------------

    So, in the next few months, there is the potential for Spirit to re-continue, as it has for 2.7 years now. Or it may take a new form; remains to be seen.

    It's important for me to be honest and say that, instead of pretending I absolutely will return to Spirit if you can just wait. I refuse to be that kind of sales / business man.

    Business-wise, for Spirit as it exists now, some might see this as "burning a bridge". I see it more as a bridge in urgent need of repair/replacement to prevent loss of life. Need to replace the old wooden bridge with a modern steel structure...


    Thank you everyone for all your support, and see you on "the other side" ! :)
