[ROM] LineageOS 15.1 UNOFFICIAL - BETA8 (2018-10-22)

[DerSteppo]

Thanks for all your and your fellow developers' efforts, it is much appreciated by a lot of us! I very much look forward to LOS 16.

How is the idle battery drain on people's XZ1C with these releases? I noticed that on Beta8 it was 0.5% / h which is oddly high considering my 5 year old Galaxy S4 Mini (1900 mAh) only had about 0.3% / h on LineageOS Nougat. With idling I mean 3G data on + sync on, with screen off and no foreground apps running, all other radios are off. Almost always battery stats show Google Play Services as no. 1 app using battery. I tried everything I knew to reduce battery life including shutting down some services and broadcast receivers from "Google Play Services" with MyAndroidTools. No help, it was still draining 0.5% / h on average when deep sleeping mostly. I even uninstalled all 3rd party apps from my phone and still I had 0.5% / h drain.

Then I wanted to see battery details, but as Oreo for some reason omits this information that Nougat had (when the phone is active, dozing, screen on etc.) I had to download GSam Battery Monitor and I noticed my phone stays highly active even when Dozing. Then I downloaded Greenify, with default settings it didn't help at all, but then I set it as rooted (my phone is rooted with Magisk) and used Aggressive Doze and this was key. The phone is no more active during Dozing and my drain is on average 0.25% / h when in deep sleep. I've tested this for a week now and it's consistent. Also when my S4 Mini Nougat was dozing it wasn't active, so now the dozing between the two phones seems to be working the same.

Downside to using Greenify's Aggressive Doze is your phone has maintenance window of once per hour or less in Doze compared to once every few(?) minutes in stock Doze, so while you get calls, text messages, Whatsapp messages and other messages straight up as they use GCM, but Gmail doesn't use it so I get Gmail emails only once, or less, per hour. Same with Youtube notifications but they're not important. I learned that Aquamail uses GCM and it works with Gmail and it looked great but it doesn't support Gmail labels so I couldn't really use it.

Maybe this is only in Beta releases? I haven't tried derf elot's newer releases. If I remember right while I used the stock Pie for two weeks the idle drain on it was also about 0.5% / h. Beta8 and stock Pie are the only two releases I've tried so far. Also noteworthy is that the reception at my home is great 3G is -57 dBm and 2G is -51 dBm, I got two cell towers within 800 meters of my house as often bad reception drains battery when one cannot find culprit for battery drain.

The first picture where I mention stock Doze I mean Beta8 stock Doze.

update: phone again seems to be mostly "active" during aggressive doze according to GSam Battery Stats especially after I restarted my phone but the drain is still only 0.25% / h.

Regards: audiofocus
When I call or get a call I simply enable and disable loudspeaker to get it working again.
A workaround until los16 or other fix

 

[DerSteppo]

I have reported the issue with the loss of audio focus to the sipgate developer team. They will check if they can get hold of a Linage OS phone to check. Fingers crossed.

BTW: Does the bug exist in LOS 16?

 

[nononomen]

Still planning on going official with 16?

Did the GPS Time-To-First-Fix performance regress for anyone else with the April build? I'm coming from the 2018-09-17 release where it was fixed ( <5 seconds) and now it's back up to 30-40.

flashing the build you were using before should work. you cannot dirty flash these builds over the betas, nor can you restore a twrp backup of /data as these ones require a format of /data. that's due to the different keys. you can only migrate by backing up apps/data from within the beta ROM (on sdcard), then format /data, flash new ROM and restore from within new build.

edit: reminder to myself: I should probably mention this again with every new build I post. it has been mentioned several times already now, but always a few pages back.

Should we wipe system in addition to data, cache and Dalvik cache ? If so, do we have to re-flash the firmware ?
Thanks in advance =)

EDIT: Interestingly, the bootloop caused by this dirty flash is avoided if I wipe the Dalvik cache.

EDIT2: I just realised you wrote "format /data". So, a wipe is not enough?

When this is going to be an official LineageOS supported device?

Hey guys, my lower speaker ended it's service for some reason and I want to send it back to an repair shop, which is why I want to flash my XZ1C with LOS 15.1 back to a stock ROM.
Can somebody please help me with a step by step guide?
I already browsed through several ones, used TFX Xperia Flashtool, got a stock ROM via XPeriFirm but I don't get the flashing working correctly.

Thanks a lot guys!

Why don't you use newsflasher with your latest firmware, which is what? .62.,80? Depending on whether you want to keep data, remove userdata.sin or use it to wipe it clean. ALSO... by unlocking your bootloader you may have voided your warranty.

 

[RootKidMitch]

Hey guys,
I'm using this Rom for almost one year and I'm totally in love with it, no issues at all.
Recently I wanted to pair the phone via miracast to a Microsoft Wireless Display Adapter but I can't get it working. Neither do I find the adapters wi-fi network, nor does it list any devices in the "Streaming"-menu...

Can somebody help please?

Thanks a lot!

Permissions in /sdcard/Android broken

Hi,
I have been using this ROM here for a long time and am super happy with it. But I am now running into a strange issue.
- A new app I have installed can't run properly and complains about not being able to read and write data.
- The app does not require read/write access to external storage, as it is only using the /sdcard/Android/data/<app> directory
- When I look at the permissions in /sdcard/Android/data, I see they are all

drwxrwx--x 3 root sdcard_rw 131072 2020-02-24 16:19 <app>

By comparison, when I look in /data/data/, I see entries like

drwx------ 7 u0_a237 u0_a237 4096 2020-02-25 11:29 <app>

which is more as it should be.

So it looks like the permissions/owner/group in my /sdcard/Android/ directory are broken. I have done some research and have learned that they are somehow governed by SELinux contexts. So I did "Fix Contexts" in TWRP, but this did not change anything.

Can anyone help?

Hey there! For LOS 16 there is a fix for broken sdcard permissions. I don't know about LOS 15.1, but maybe this hint will help you as well:

with all my respect, can anyone get back on Lineage15.1 and release a stable no bug version? cuz to consider the battery performance for this phone android 9 or 10 are no better than 8.1. so if some developers can look back, and get on the most suitable android version rom for this phone i believe lots of ppl will be happy abt it. with all my respect from China!

This makes no sense, what you are writing about.
The best battery duration I got with LineageOS 17.1!

That makes perfect sense, since Android updates gradually improve the battery performance of the system (usually).

A question: if i install this lineage os on my device can i use my sony apps like xperia xome,nusic,album etc? Thanks

No, These won't work any more with the exception of the camera app.

However, I would not recommend to moving to LOS 15.1 any more. There is also 16.0, and 17.1 available by now.

Hey! There is a magisk module called 'Sony device dummy' on the magisk repo that once activated, will allow you to see, download and install all Sony apps on play store.
Another way might be to use 'MagiskHide Props Config' magisk module to change your device fingerprint to that of your Sony device though I can't remember trying this myself due to the handy nature of the former module. I suspect it works just fine though.
