Sure, but you loose nothing trying.

BTW:
Recording works like AK-47.
Was very useful the second day after I succeed get it acting.

I found this:
Didn't read.
Myself I seek a word about Daily Job Scheduler.
At least working command line which would give me pattern to compose my own one.

Hence we keep nearly all A41 related information here I can tell that while ago I upgraded Android to version 11 which appeared 1-2 days ago on sammobile.com.
No problems at all.
I modified AP_* by the book, downloaded it to phone and voila!
Not even lost apps, personal settings, call history, contacts etc.
I feared I will have coming night sleepless but bit of luck is worth more than tons of hard work sometimes.
One thing:
Magisk fails when I want it to hide it but it hides itself from applications and while my bank apk works IDGAS.

Anything what you will bring to the table will be appreciated.
Myself I am not on level which allows me to work on things like you mentioned, but I'd enjoy seeing TWRP, yes.

I would need someone to test the TWRP I build. We can chat on telegram with group chat or personal chat. here's my telegram @cha0scl0wn.

@F308

I think I read Android 11 breaks video recording with screen off?
(Like with this app.)

And while Samsung's OneUI 3 may have some improvements, it seems there are also downgrades. Has the full QuickSettings screen become 3 lines instead of 4, or app drawer folders 3 icons in a line instead of 4?

Well.
Bit of weird to record video with screen off.
Anyway I am not much interested in recordings.
I don't know exactly what you mean with QuickSettings.
If I've seen image would be helpful.
Concerning icons on screen I don't know, I had 6x5 icons on screen and it remained this way after upgrade then I don't know how initial setup looks like.

There is native call recording but having Magisk module which you provided to me I don't know how it works.
Will check one day after disabling module.
Right now I am checking what is different comparing to Android 10.
It would be good to have list of Samsung Android 11 bloatware to freeze.

For the records:
I finally passed through SafetyNet check.
Switching off debugging was final change which helped.
I missed this point earlier.

/optics/configs/carriers/<3-letter-csc>/conf/cscfeature.xml

Decode the XML with OmcTextDecoder. No need to reencode before using it back on the phone.
Hello again.
Do you remember this discussion?

I wanted help a friend and activate recording on his Galaxy S9+.
First - there was no such path like above.
I found cscfeature.xml file under /odm/etc/omc/XEO/conf, modified it following former method which was working on my phone, but it does not work.
I attach this directory zipped and final stuff, if you would do me a favor and have a look I would be grateful.
Maybe you will discover something what I missed?
Maybe variable allowing recording differs from A41?
This is the point.
I checked presence of modified cscfeature.xml in place where it should be, that means mounting module directory by Magisk worked.

Thank you in advance.
Have a nice day.

I think it's somewhere else. Maybe like this one:

The CSC setting name is probably the same.

Best continue under the S9/+ forum... :)

Thank you.
I was there however have still lot to read.
Looks like despite the same Android version behavior differs, necessary actions follow.
Surely I will try.

Sorry for late reply.
I came to the idea that I could try while I am not busy what recently was the case.
I don't use telegram but for a while we can communicate here via private messages if not in posts.

/optics/configs/carriers/<3-letter-csc>/conf/cscfeature.xml

Decode the XML with OmcTextDecoder. No need to reencode before using it back on the phone.

I copied all the files from that directory, modified the XML, and overridden the original directory with a basic Magisk module.
Again after certain delay, new related question.
Is there a way to override only one file, not directory?
One cannot "mount --bind filename" and duplicate big directory where only one file differs from original may be troublesome.

Hi, can someone confirm that there's no CSC with call recorder enabled out of the box yet? AFAIK with an official CSC it should be possible to flash with Odin keeping knot & so on... I'll root it sooner than later but this phone is not for me and I'd like to keep it stock for a while if possibile (OTA stopping is the deal breaker here).

TIA

BTW, still no A41 subforum on XDA. The admins must have something against this model. :)

Not sure. Try asking under the big unwieldy Magisk thread:

But why not copy and override the whole directory? Unless you mean it's many MBs.

I haven't looked in recent months, but AFAIK the model wasn't officially released in countries where Samsung enables call recording.

It's a 2020 model, so probably no more variants since then, but check the firmware sites to see if you spot any suitable countries. There's a list of candidates, I don't know if complete, here:

Yes, this was always a solution however mounting /system/etc would interfere with hosts module which is there thanks to Magisk.
I could overwrite one action by another.

I wanted change /system/etc/gps_psds.conf.
There is line: NTP_SERVER= ...
which points to North America, guess for all worldwide ROM-s.
I preferred to point it nearer, to my country NTP server.

In the meantime I kinda cheated.
I loaded modified gps_psds.conf to Magisk hosts module directory, /data/adb/modules/hosts/system/etc/ and it worked using "coleague's" functionality.

Not sure how hosts file is mounted under /system/etc, though.
This module is likely embedded since some time and doesn't work alone.
I loaded there my own hosts file, too.

    What's the deal with the Samsung Galaxy A41?

    For reference:
    https://en.wikipedia.org/wiki/Samsung_Galaxy_A41
    https://www.samsung.com/A41

    👉 There is no XDA-Forum for this smartphone
    👉 There also seems to be no community for this phone.
    👉 Searching the internet for A41 compatible Custom ROMs ends in less than nothingness even in the darkest corners.

    What's going on? The phone is on the market since March 2020. The phone is pretty good in specs (middle-class).
    AND it is the ONLY phone under 200 bucks today that is NOT larger than 150mm in length and therefor usable in pockets.

    I don't get it why it doesn't get the same attention as the other competitors in the same price class.

    Can anybody enlighten me what's happening?
    Please XDA mods and admins, if this is just a mistake, please open a samsung forum for the A41!

    I bought a new Galaxy A41 for 180€ and I'm just setting it up.
    I want to share my thoughts so far about:
    the hardware, the software, things like rooting.

    The Installation and Software:
    The phone starts and already wants to trick you into signing data collection agreements (Terms of Service (not optional), marketing, analytics, 3rd party shares (3 optional)).
    If you select by common sense and only check ToS you'll get fooled when you check the last radio button which says "I've read all of the above and agree (..)" which enabled all optional radio buttons again right before you click next. What a dirty play.
    Also it is not possible to skip the WiFi selection screen ("skip" is greyed out) making it impossible to setup the phone without internet access. This has nothing to do with FRP, this is before anything google related is setup. Samsung clearly states it requires internet to setup the phone and install necessary provider software. Once it gets internet it gets activated and the "skip" option becomes clickable after the next factory reset. This practice makes me really angry. It's obviously the price you pay when you buy a low- to mid-range class phone - you'll pay the rest with your personal data.
    I setup the phone without creating google and samsung accounts (I never got one of these anyways) and got to the home screen. If you havent enabled WiFi yet, there aren't many apps at all pre-installed, just a few useful and a few bloatware apps (like Facebook, MS Office, etc).
    If you give it WiFi however, it kinda explodes with leeching, loading and updating Apps you never asked for. Only some of these can be "disabled" and only some of them can be "uninstalled" the normal way. Some of the unwanted you can't uninstall nor disable. (This is where you wish you had root access)
    The phone had Security Patch Level installed from August 2020. Making OTA firmware updates 3x (about 1-3gb) will get you to Sec.Patch Level November 2020 which is the latest available OTA (we have February 2021 now). That's not a good sign IMO.. so it's already a few month behind the patch cycle..
    So, software wise there aren't many useful apps for me installed, really just the utter basics and much more 3rd party bloatware and Samsung nonsense apps. It's not as much as with the Poco X3, but still much...

    The Hardware:
    The super amoled display is the biggest feature of the phone. and it's really great, the colors, the viewing angle, the brightness.. all top notch.
    Battery is with only 3500mA/h not that big, but it's astonishing strong and it holds up the uptime it promises so far. I can only hope it stays like that even after a few years.
    The size of the phone is what actually made me buy this phone. its the only phone under 6.5" under 200€ and not older than a year. all newer phones are bigger. The size is great, it's slim, but long. (6,1" ~15cm long)
    I didn't expect it to be that heavy, though. well, the weight is not really heavy, but compared to older phones it is a good bit heavier.
    The Camera is just Mediocre, I already knew this from reviews before but playing around with it and seeing the results underscores it. The final pics alltogether look always a bit washen out if you zoom in. There aren't enough professional advanced settings in the camera settings compared to open camera or mx camera. you have to stick with what you get. The Sensor of the camera is despite 48mpixels only mediocre. the widescreen lens is a nice feature but quality wise not that good either. Selfie cam is subjectively good enough though.
    HDR setting and results are a joke compared to mx camera.

    Rooting:
    I actually planned to root the phone with magisk and installing TWRP. However, I ended up not rooting or installing TWRP at all. The reasons are various.
    First, It's possible to unlock the bootloader in developer settings (after the phone called home..). You'll get a nagscreen every time you boot the phone up after it's unlocked. From this point on you might be able to root the phone with Magisk (following the advices a few posts above), but it'll probably trigger and brick KNOX status.
    I decided to NOT do that and relocked the bootloader, because there seems to be no lively community for this phone, there are no Custom ROMs available nor any custom bootloaders. And I might want to sell the phone again if it doesn't fit my likings and that'll be more difficult with broken KNOX status. Also that way I can get OTA stock updates as long as the phone is supported.
    There is also no supported version of TWRP for the A41. And TWRP on phones like this is tricky as you can read at the A40 TWRP page: TWRP A40 read chapter "This device uses system-as-root in an A-only partition configuration." Also the device is using File Based Encryption and not Full Disc Encryption. I don't know if TWRP works with that environment at all yet.
    So currently the only benefits of getting root would be to be able to completely uninstall some bloatware. The rest (firewall, adblocker, backups, etc) is pretty much possible without root access.
    I really hope this phone is able to get custom ROMs and community in the future, though.


    Hi all!

    I have one of these since a couple of days and I have to say it is a really nice phone with a really bad issue: the jpg compression is super aggressive
    and photos that should look great given the lens and sensor look bland and smudgy. As far as I understand, there is no camera api2 exposed at all by default. All camera apps that I have tried produce worse images and gcam does not work (I have tried about 20 different ones, for Mediatek and otherwise). If Samsung could just let me bump up JPEG quality to 95% I would be completely satisfied with this phone, but I guess that would never happen.

    I therefore wonder, is there any chance that your success rooting the phone could lead to bumping up the JPEG quality of the stock camera app, eventually expose camera api2 or somehow allow us to install a version of gcam down the line?

    Cheers!

    I exactly know what you mean as I watch the pics I just made with the same phone. I don't know if you could change anything in this regard after rooting but it actually looks to me like it's rather the built in camera sensor that makes the quality not that good and not so much the jpeg compression. It doesn't really look like jpeg artifacts, it's more like a washen out painting. I doubt you'll get anything better by rooting the phone, but thats just guessing. Also: did you check out the Image format options? "4:3" vs "4:3 48mpixels"?

    Got the phone yesterday (about 120$) and got it rooted with Odin and Magisk took a little back and forward.. been a while sines I have been on Samsung phone.

    I like this small cheap compact phone, tired of the big bricks.
    Was installing from a new phone with latest update from Samsung.

    So wrote a small guide to help out..

    Everything on phone will get wiped/factory reset , so take backup , you have been warned.
    Take no responsibility of brick etc. (or typos!)
    !PLEASE CHECK WHAT VERSION PHONE YOU HAVE MINE IS SM-A415F AND THE GUIDE WAS WRITTEN FOR THAT PHONE!


    Quick guide:
    1* On PC or phone download you stock firmware for you region: https://samfw.com/firmware/SM-A415F
    My was NEE witch is Nordic Europe.
    Unpack or Transfer the AP_* file to you phone, i used microsd so didn't unpack on phone.
    (sd card need to be exFAT , you can format to that in Windows, so it cant handle big files over ~4GB)

    2* Install lates Magisk manager from https://github.com/topjohnwu/Magisk/releases/latest (Used v22.0) on phone.
    Install Magisk patch the AP_* file from before
    Transfer it back to PC, we will use this later!

    3* Start phone, (if new phone don't bother sign in google/samsung etc.. it will all be wiped/factory reset!)
    Enable Developer mode:
    Setting, about device tag 7 times on Build..
    (If its not shown connect to the internet and wait ~5min..)
    Check "OEM unlocking" , "USB debugging".

    4* Turn off the phone, press volume +/- while you connect PC to Phone with USB-C.
    When screen "WARNING...Custom OS can cause problems.." press and hold Volume +, and press Volume + to confirm what you are doing!
    Let it reboot.

    5* Enable Developer mode:
    Setting, about device tag 7 times on Build..
    (If its not shown connect to the internet and wait ~5min..)
    Check to see if "OEM unlocking" is greyed out enabled , check enable"USB debugging".

    6* Turn off the phone, press volume +/- while you connect PC to Phone with USB-C.
    Press Volume +(don't hold like last time.)

    7* On PC open latest Odin (used v3.14.4) from https://odindownloader.com/ (no sure it that the official site but what i used, please let me know if there is a better one.)
    Unpack the folder to your PC hard drive and start Odin3*.exe, uncheck "Auto reboot" make sure "F.Reset Time" is checked.
    Use the original firmware files from (1*) "BL, CP, CSC" BUT the AP_* that you transferred from Phone.

    Press start and hopefully you will get a "<OSM> All threads completed. (succeed 1 / failed 0)" when it's done!
    Restart phone.

    I had to download magisk and install it again but everything seems to be working..

    Cheers

    yepp - I have such an 'outbreak of hell' product - still struggling to root this beast. 90% of the references in the i-net are fake/copied from other Axx or just bla-bla.
    Up to now odin (different versions) seems only to be able to flash Samsung CRAPROM (needed it several times after ended bricked)
    - magisk patched boot img not working/ending up in boot-loop,
    - magisk patching AP dies before finishing (img is 3.5GB instead 4GB)

    Samsung - not a success story
    1
    2* Install lates Magisk manager from https://github.com/topjohnwu/Magisk/releases/latest (Used v22.0) on phone.
    Concerning the above.
    Would you kindly tell what stub-release.apk visible there is for?
    Is it needed?

    I've recently bought A41 and root access is what I miss a lot in it.
    I rooted phones in the past then I have some experience which caused that related questions came to my mind.
    If anyone can answer them it would be for use for me and others.
    Those are, maybe obsolete but better to be on the safe side.

    Question Zero:
    Is the rooting possible to revert?
    This probably affects warranty AFAIK then it would be good to have way back to original state.

    1. What about certificates?
    Past in time there was TA partition which had to be preserved before unlocking bootloader.

    2. How it is with updates after rooting, eventually how to stay safe when Android 11 comes what is expected in the middle of the year?

    Thank you in advance.

    #----------------------
    Added 2 days later.

    With a bit of fear I succeeded to root my phone.
    Software version was A415FXXU1BUA1.
    (https://samfw.com/firmware/SM-A415F/PLS)
    I
    have problem with SafetyNet status, though, see picture.
    Should I worry?

    Concerning point 2 I found sort of answer.
    AP_* should be patched again before flashing.

    #------------------
    As long as it will be possible to edit this post I will inform you about my adventure with rooting by using Magisk.

    Today I installed Xposed and NFC active over locked screen modules for Magisk and went into bootloop. Not sure which of them was guilty.
    I flashed patched software once more and observed that I am short of space, system screams.
    Unfortunately I don't know how it was first time, because bootloop came all of the sudden.
    What is funny is fact that one of file manages show 4Gb of internal memory while other 8Gb but both full to 95%.
    Where is rest of space?
    It should be mounted or mentioned anywhere.

    There's no TWRP recovery for Galaxy A41. Bad luck, too.
    SafetyNet fix is not available for Samsung at this moment, either.

    I've read that Magisk manages many things then it should be possible to manage space, but how?
    I didn't find anything related.

    Any observations and comments will be appreciated.

    #------ Final action -------------------
    Factory reset fixed problem.
    Good thing that root access still remained.
    I have enough for now.

    BTW:
    Looks like bootloader returned to locked state, see picture.
    SafetyNet is still red, though.

    Worth to know:
    Factory reset didn't revoke my changes made under /system, probably because programmers didn't consider that anyone will be messing there.

    Could someone make me a favor and provide fingerprints from original A415FXXU1BUA1 ROM?
    I am trying to get build props from it but due to lack of experience it takes time to unpack and seek through whole this stuff.
