- BPF specific functions like fancy new GPU monitoring in Android 13


Keep in mind that some LineageOS features have not been completed yet this is not a device bug and please do not report those
Also do not post bug reports for known issues or bug reports without proper

c) data/tombstones
d) dmesg



Install gapps right after installing the rom itself don't try to boot to system before that if you want to use gapps (Or wipe data before installing them)

NikGapps have been updated to 13, you might need to clean flash if you used other gapps in past including nikgapps 12.1 version

Make sure you are using latest official TWRP before installing rom older versions do not have proper android 12/13 support

Thank you Ivan for your work. But I think the ROM isn't ready for daily use. Standby battery livetime 6 hours only instead of more than 20 with LineageOS 19. And a lot of crashes in apps like K9-Mail, Filemanager+, Google search,... I go back to LineageOS19 and wait for a stable release of LineageOS20.

Keep in mind that some apps need to be updated to be compatible with android 13. This is mainly not a rom issue. The app developers need to update their apps as usually on every major android update

From me a big thanks to Ivan too, but I have exactly the same issues.
The battery drain is very huge. While watching YouTube it is like 0.5% per minute.

The App crashes are really weird, sometimes they crash permanent sometimes they dont and after a few restart is working again.

Contacts importing wont work because of missing rights, somebody knows how to fix that?

And sadly while making a phone call the called person is hearing a hugh echo.


Keep in mind, to go back to Lineagos 19.1 you have to wipe all data or you will enter a boot loop.

    Hello,
    as far as I know, Ivan's (@Ivan_Meler) sources are also used by Exodusnick for his microG version of LOS. I am still looking for a solution to the echo problem that exists from LOS 17 onwards at least for a part of the S7 devices, so I did a file comparison (all files with "audio" or "mixer" in the name) between LOS 16 and LOS 20.

    Unfortunately, I know far too little about Android. But maybe a developer can see a possible cause for the echo problem from the differences in the files, which we can then work on further. For example, I am surprised that the file audio.primary.universal8890.so is missing under .../hw/lib64/, although the S7 has a 64-bit OS (at least I think so).

    I would be happy if someone takes the time to have a quick look at the comparison. Maybe we have overlooked something quite obvious so far.

    I think it's such a pity that because of the echo you can't use all the new ROMs in everyday life and have to stay with LOS16.

    Thank you
    kjoe
    sorry to say but that comparison of files you did is completely pointless and useless, trust me if it was as easy as comparing files somebody wouldve done it

    To everyone who is facing the issue of apps not opening, I isolated the cause to be formatting SD card as internal storage. Right now you can only use SD card as portable storage.
