all app permissions were set to no permission,
what are the default permissions for system apps?

System apps usually get their permission set from default-permissions folder, but you can try to reset app preferences found in settings:

After setting up the google authenticator instead of sms i could log in and set up my fingerprint. However on the following login attempts it takes my fingerprint, is busy for a bit and then throws me back to the fingerprint input.

Not Working
- HWcomposer (HWC) (temporarily disable due to crash it caused)
- System is running some debug in bacground and that combined with no hwc might make it seem a bit slower
that will be resolved soon treat this as preview build

still true? :)

Yes, they're still present, you can override the slowness, at a price, or you can have faith in Ivan and wait for him to stabilize the ROM.

Hi,

No issues so far, also battery last longer as 17.1, but w/ my company phone, I can't use TWRP w/ encryption, since can't mount data. Is it working for anyone?
Thanks

Sorry, encryption/decryption is not supported officially, if you need root, you can simply flash it using an external sdcard, Magisk can detect your encrypted partition.

It has some workaround for gaining root with keeping encryption, maybe by putting everything on /cache then copy to /data, IDK exactly how.

You can try your luck with command <twrp decrypt PASSWORD>.

Been using this for a week or so. No issues. Very smooth and great battery life.

For those who mention the in-call echo problem, is it happening on your S7 handset or is the echo a problem for whoever is at the other end of the call? I have not noticed it at all from my end but one or two people I have been speaking to have mentioned an echo on the line. Thanks.

I have had the same problem in the previous build, wasn't able to test this one. Apparently nobody wants to speak with me. What worked for me sort was turning down the volume, it almost got completely rid of it. It isn't a glamorous solution but it works (sort off).

I have had the echo problem for a while and I call my landline and leave a message to check. It was so bad that i could hardly understand myself so i investigated a bit and read that reducing the call volume below 50% would help. I tried it at around 30% and almost all of the echo is gone. I have not changed my speaking level to compensate.

Hey guys, where can I find the previous build of LOS (from around 13/1)? Unfortunately, after applying the latest build today, phone is caught in a boot loop :-( Hoping this could be resolved by flashing the previous working build, but cannot find link to download it here... Thanks!

Did you
Before installing January 2021 build remove fingerprints and delete /data/system/locksettings.db this is needed due to mobicore version change which helped fix fingerprint with 3rd party secure apps
before flashing the latest build?
I have no idea where to find previous builds.

sure, did that remove&delete, though did not work out... reverting to previous working build could help I guess

    Here we go, March security update is here.
    LineageOS 21 builds wont get update this time around as new qpr is still being merged and fixed up
    There were a lot of changes from google in their quarterly platform update soboth LineageOS codebase
    and some device changes are needed for it to be on par with previous builds.

    There will be april builds for it soon so it made no sense to push half baked update today.

    As always huge thanks to everyone who donated to help cover the build server cost.
    This project wouldnt be possible without you.

    Enjoy new builds and stay safe

    - Synced with LOS source
    Not too many changes in this one as you can see as i spent most of the time focusing on LOS 19 build (Android 12)
    which is coming along great (Just some gralloc work left to do and sensor hal needs some attention before first public builds)
    Big thanks to everyone who supported this project as always as its thanks to them that this project is still up and running, Enjoy new build and stay safe
