LineageOS 19.1 (Android 12L) [Signature Spoofing][OTA updates] for S7 Exynos

[GrgMdmn]

My system is unstable... Do you think it might be due to the gapps that I installed ? Mine is nikgapps NikGapps-core-arm64-12.1-20220908-signed.zip

Edit: I tried with BitGapps and that was better. However, still crashes. I have nextly gone back to the stock samsung rom, and I encountered crashes too. My conclusion is that my phone has hardware problem, so I will replace it and try later. Sorry for bothering

Unfortunately I confirm I have phone echo issues with this Rom since I installed it (fews months ago), and with every following update.

The echo is not on my side, my caller can hear it's own echo on his side. Seems like my mic is recording sound from my speaker (at low level but still)

Is there mixer_path tweaks to try, or something else to flash ?
Or is it possible to check another Rom mixer path file ?

Have the same problem with my girlfriend's Galaxy S7 with lineage OS onboard. SInce installation, I hear (on my Xiaomi 9T) terrible echo and hissing distortion of her voice. Can anybody help me?

I'm having this same issue. It seems that apps that don't rely on some form of phone call service/voIP (like the Google Recorder app) work just fine with the microphone. I can't hear anything that seems out of the blue, only the fact that the microphone (at least from what it seems) records audio a lot quieter than it use too.

The quiet microphone sensitivity seems to also carry over to the VoIP / Regular Calling apps as well. The Interlocutor can hear their voice briefly for a small amount of time shortly after they speak.

I think the reason why this happens is because the S7 has 2 microphones on the top and bottom. I noticed that the top microphone (at least from my findings with settings pages, and different apps) cannot be configured for use. The default microphone the phone uses is the one at the bottom, located close to the speaker.

I tried looking around many places (including XDA) in different places from Magisk Modules to Lineage updates, but it appears that this is a known issue with very minimal knowledge as to what is causing it for some people.

I hope this gives insight to anyone actively investigating the issue, though I do admit it's pretty surface level observations.

Thanks to everyone for making this possible, especially Ivan Meler.

(I'm using the Canadian G930W8 variant of the S7 in case anyone was wondering)



Edit: I forgot to mention that I tried installing different Microphone mixer_path patches, alongside having AML (Audio Modification Library) installed, but it seemed to not resolve anything. I will likely continue my own digging with this as I'm not too accustomed to what it fully does yet.

Hi Forum,

first of all a Happy New Year to all of you!

Many thanks to @Ivan_Meler for your tireless good work and efforts!!!

May I ask, whether the usage of SD-Cards works now in LOS 20? (Sorry, have asked that in the wrong forum!)

I'm having problems with front camera.
It works fine with camera app installed from twrp. But front camera crashes with any other app from app store.
Does anybody know how to fix this problem?

Hmm just applied the latest lineage-19.1-20230105-UNOFFICIAL-herolte and my trusty S7 is now bootlooping - downgrading it back to lineage-19.1-20221206-UNOFFICIAL-herolte has surprisingly not fixed it either and the phone still bootloops.

I'm on the fixed version of twrp-3.7.0_9-0 and to upgrade I did the usual reboot to recovery, wipe caches, sideload lineageos + Magisk 25.2, reboot so exactly what I always do. Anyone else seeing this or have any ideas?

Disregard that, I belatedly realised I forgot to reflash NikGapps with the ROM update... which I have a funny feeling I did last time as well. Whoops . I had to rebuild the phone last time as well which I'm definitely going to have to do again now.

This does seem to bring up a weird issue though - if like me you use NikGapps and forget to reflash it during a normal ROM update you're out of luck. Reflashing properly with NikGapps again will resurrect the phone ok but the Google Play Services are then permanently kneecapped: the playstore app is forced into "you're offline" mode and Signal etc immediately die as their playstore integration is cut off. There doesn't seem to be anyway to recover from that without rebuilding which is... unfortunate.

Don't get me wrong, this is entirely my fault for forgetting to flash NikGapps but this seems a little odd. Anyone else run into this or am I literally the only person who's ever forget to reflash the Gapps package during an upgrade? I know I've accidentally forgotten to flash OpenGapps during a S7 lineageos upgrade before without this happening.

Normally nikgapps should Backup your gapps and restore it after every Update. Dont know what did go wrong in your case

Thank you for providing this ROM!

In case someone wants to use it in combination with Family Link, I did get that working only with MindTheGapps almost out of the box, whereas several other GApps distributions got stuck.

The only problem with the MindTheGapps version I used was this one: https://forum.xda-developers.com/t/missing-options-in-recovery.4256195/page-2, where there is also info on how to fix it (you need to make a small change to a file inside the MindTheGapps zip before loading it).

Am I correct in assuming that this OS does not support exFAT on SD cards? I just installed it on my S7 as a test and the inserted SD card with lots of files is recognized, but it isn't readable.

Well, easiest would be to solve that, that you copy all that files from the SD card onto your PCs (or Notebooks) harddisk, then format the SD card inside the Samsung Galaxy S7 as removable, and when this works, then you copy back the files from your PC/Notebook back onto the SD card.

 

[fipsy]

Okay, it's clear that it will work this way. So Lineage 19.1 no longer supports exFAT? Because Lineage 17.1 still supported it. As well as NTFS. Although there were also some problems and bugs with exFAT.

With which file system does lineage format the SD card? ext4? Then it would no longer be readable on the PC. It would be important to take a file system that is readable and writable with lineage as well as with the PC!

Well... when I format an SDcard inside the S7 as removable (NOT as internal), then this SDcard is also readable on my PC too.

But: I am a Linux user, and honestly never worried about, what file system does that SDcard have. Linux reads and writes nearly everything.

I have a second PC running Windows 10, so I will test that on it and give you a reply.

Maybe someone here in the forum knows more about that, but normally an SDcard formatted in the S7 as removable should also be readable/writetable in Windows.

Addendum:
Just have testet that issue with a freshly mobile (removable) formatted SDcard, I had formatted inside the S7. The OS on that S7 is LineageOS 19.1.

Windows 10 reads and writes it properly. The S7 with LOS 19.1 formats the SDcard as exfat.

Hope this helps you.

Thank you very much for the test! But it leaves me a bit perplexed. The sd-card that lineage 19.1 cannot read is read in TWRP with no problems and was also read with no problems on lineage 17.1 and on Windows. And it is formatted exFAT. So obviously there are technical differences between exFAT formatted with lineage 19.1 and exFAT formatted with other systems.
