You can just use the file explorer in twrp to remove whatever you want, just find the appropriate apk files. (see at app&notifications, click see all apps, click app, advanced and at the bottom you find the name of what you are looking for, as an example gmail becomes com.google.android.gm)

I personally do it in a script that I flash after the rom and gapps.

Some of you do warn about troubles if you remove the wrong files but in my opinion this is not a big deal, just reflash everything if you've gone to far, (script comes in handy there lol).

Is it really necessary because there are other options? No of course not but I like my phone "Lean and Mean" :laugh:

I did this too with my older S2 because storage did matter back than.

I also do other things in this script like change the bootanimation with a shorter (and of course cooler) one. -> my phone boots up really fast because it does not have to wait for the animation to complete.

I also put my custom ringtones, alarmsounds and stuff on the system partition because one time I missed my flight because the phone had troubles finding the sd card after flashing a new rom and the alarm went of silently... :eek:.

And of course some tweaks like increasing volume steps of bluetooth and stuff.

I also have the same problem with receiver not hearing me. This works on the 11th August version but unfortunately not on the latest version (11th September). My phone model is standard UK S7 (SM-G930F).

No Luck Installing

It seems very strange but I have one S7 (G930W8) that will not boot the last 2 versions of Ivan's ROM. It works fine on the 20200805 version but will not boot on the newer ones. It just boots for a while and then goes back to TWRP. I have tried many times clean install and also a dirty update from the 20200805 version but the result is the same. I have other similar phones and they all will boot from the latest version. I have attached the logs from the install if anyone can decipher the problem.

This phone is one that is in good condition and it would be nice to be able to update it.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Jcth1:
I too have had bootloop or crashing issues on my 930w8 with latest 17.1 and I was on build 30 of 16 for a good while.

First random crashes started with me using Google pay and adding fingerprint security.

Phone eventually barely booted without crashing or reverting to twrp so I managed to salvage my WhatsApp chats in twrp then reflashed 17.1

It fires up but as soon as I try to do something on the phone it crashes back to twrp or tries to reboot.

I asked how to find logs so maybe I can upload but my question went unanswered in Q and A

Rolled back to 0811 build, low audio recording issue was fixed. Problem with google play film crashing if pushing volume button is still present tough; since this doesnt happen with YouTube or VLC (as example) narrows the scope of the problem to something application-related.

You can solve the issue where others cannot here you when calling via wifi by using the mixer_paths file from previous build.

Or flash the InCallEchoFix I've dropped here, it copies that file for you and has some small modifications that do really improve echo stuff for me.

Does anyone understands all values in the mixer_paths?If only we could clean/refactor the complete file we could make this rom even better.

[MENTION=4610599]Ivan_Meler[/MENTION]

Do you know where we can find more information on values in this mixer_paths_0 file (if it exists)?

Maybe we can help in figuring out all correct paths and values in it.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Hemuli:
AFAIK, the file is related to TinyALSA, and is commonly used by Qualcomm equipped devices. That's a starting point to what's happening under the hood. It's a highly configurable system. I don't know how easy it is to see how it's configured for our device, which would be important to know what each value actually means and does.

Hi,

I have the same problem as Syrtakimann. On mobile connection some connections do not work. Like WhatsApp will work but Signal reports no internet. Opening Google in Firefox works, but duckduckgo does not work. Directly pinging the Google IP address also fails (pinging any remote address fails). Maybe the failures are protocol-based and not connection-based.

I installed the most recent modem files (BL and CP). On Wifi everything works perfectly and my Bluetooth range is excellent.

Does anybody have a solution for this?

Thanks.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Kernle 32DLL:
Now that you mention it - I did have weird connection problems. Turns out for me (Germany, T-Mobile provider) the APN settings were wrong, and I had to edit them by hand to match what my provider provides. Sorry for not remembering that earlier. Maybe you could give that a try.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] ndevln:
Thank you so much. I have congstar (Germany) and it worked.

The problem was not the APN Configuration itself, but the APN-Protocoll. I had to switch from IPv4/IPv6 to IPv4 only.

This is reproducible and explains why the failures were so selective. Every time any app tried to use IPv6 it just failed and IPv4 Apps just worked.

Thank you, kind stranger :)

No I tried to disable the top microphone when in call (so only using the bottom microphone of our phone)

I posted the exact changes in:https://xdaforums.com/showpost.php?p=83372251&postcount=1174

This echo fix really works right after you changed/flashed it but it seems that after a while the echo comes back.

I think it depends on what paths are followed in the mixer_path file so that after a while the top microphone gets enabled again or something.

Hi

I have been using LineageOS since it was a Cianogen and everything always works well in my phones.

But yesterday, a bank app stops to work (after update) and says that it is not supported in my S.O.

Is there any bypass to this kind of block/verification? I have tried magisk manager and magisk hide with no look and I wouldn't like to abandon LineageOS because of it.

Thanks and best regards
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] rdelmont:
Usually if the app blocked BEFORE installing magisk, you should try to delete the app cache before trying to use magisk hide and open the app again. But it really depends on which kind of checks the app implements, I have some not working anyway.

Persistent call dropping

Despite all the effort that has gone in to developing this version of LineageOS, I couldn’t live with it.

Just a few small mishaps. Overall it works beautifully, but my phone suffered from severe battery drain which I couldn’t pinpoint, recording volume was very very low and the echo during phone calls returned.

I went back to the latest 16 build and my phone is much more usable now. A shame really, I upgraded to 17 mostly because of the security updates. Guess that will have to wait.

There’s just one big issue that got introduced after my upgrade to 17, and that’s call dropping.

Whether I receive or make a call, it will drop somewhere between right away and 10 minutes.

I thought I fixed it by flashing an official Samsung modem image, but it turned out to be random luck that I managed to have a call the lasted for over 8 minutes.

Since then it’s been all over the place. Some calls drop right away, some last for a few minutes, but never longer than around 8.

I thought it was an issue with LineageOS 17, but it has persisted after going back to the latest 16 build and I’m not sure where to look for answers. Doesn’t seem to be a common issue if I look at this thread.

I checked the APN settings and as far as I can tell they’re fine.

For now I resorted to using Whatsapp for calls but obviously that only works when I initiate a call to someone that uses Whatsapp, not when I receive a normal call.

I guess the next step will be to finally get ADB working on my computer and grab some logs. Or just get a new phone, although that seems rather silly considering my s7 still works OK except for this one nagging issue.

- enable magisk hide, installed and selected only my bank app

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] rho-bot:
No need to worry, this is normal, you can disable the warnings in Trust settings.

LOS decided to make selinux enforced mandatory, as a prerequisite to get official status (and to be build & signed with official LOS servers).

As Ivan could not spend this effort, this LOS is selinux permissive, and therefore has to be signed by his own keys. => Unofficial LOS
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Wattsensi:
Indeed, this device tree is capable of enforcing SELinux and is used by default, but CONFIG_SECURITY_SELINUX_DEVELOP=y is present in the enforcing kernel's defconfig so it can be put in permissive mode, which disqualifies it. Look
