Translated by Google.

Tried several launchers, including brand new ones.
Notification access cannot be set for any launcher.

I think it is due to Lineageos 19.1 + Lineageos 20.0

Hallo Ivan, fantastic that you develop S7 for android 20. I tested the last image and all was fine, but the battery drain is awfull. In onely 1 day it drops from 100% to 38%. So you had to load the akku nearly every day. That is too much.
Can you give us tips in the configuration for battery performance?
 
@carli_nero:
Maybe if Lineage OS 20 Support Batterysaver Mode?

First impressions of the Rom is great for me.

All working except (maybe only because Android 13 too new?):
- Paypal App, Sparkassen Banking Apps, Intune App (require device encryption)
- Clock - Alarm Labels to small if edited label names

Whishlist:
- Root access
- Device Encryption
- Working Banking Apps, Paypal and Intune Apps
- Change display resolution (can't find into settings and I I mean, I have only HD ready resolution 720x1280 active)
- DPI Settings
- Hardware keys lights (isn't a device tree bug or this dev)
- Device very hot if loading
- Batterysaver option
- Screensaver functionality (is there but not working)

Banking apps work for me, why not just flash magisk for root? 25.2 working flawless for me.

Just did a clean installation, no GApps. I encounterd 2 issues. First when I swipe up there is no app drawer, just an option to search for apps which also doesn't work and second, I can select gesture navigation but only the swipe up function works. When I swipe to go back nothing happens.

Did another install and again same issues. The md5sum checked out fine. Any ideas?

Go to settings>Wallpaper & Style

Scroll down to App Grid and change size to 5x5 or lower, That should fix it.

Great, everything's working so far, its just when unlocking the device it crashes and goes back to the lockscreen on first attempt and screen recording is broken while recording a video longer than 10 secs, the system ui crashes. everything else is working perfectly well.

Android 13/LOS 20.0 looks and feels great on Galaxy S7!

However, it worked well for 2 days for me, but now I'm stuck with most apps constantly crashing after a couple of seconds (seems to be related to apps using the network connection, system apps like camera, gallery etc. work fine). I don't get any crash reports or error messages. Whenever I open an app it crashes back to 'desktop' (what's that thing called in Android? :D)

I'm running latest TWRP (3.6.2.), did a clean flash and use NikGapps Basic with latest Magisk (25.2).

Any idea on how to solve this issue? In this state the phone is almost useless (except for calls and sms - but who still uses those). Help very much appreciated.

Webview related apps started crashing for me sometime after installing the initial build,.

What I did is, Wipe system, Install latest build , NikGapps-Core, And Magisk.

I suggest you give it a try and see if that fixes the problem, Not sure if that's what fixed it for me though.

Alright thanks! A quick wipe of system+dalvik-cache and reflash of LOS+NikGapps-Core+Magisk did the thing. Although it makes me wonder how long It'll work this time and what caused the crashs to begin with.

    Hi, first thanks for your work on keeping this device alive.

    I'm still on 19.1 currently, which works alright for me. I've recently found out that it does not support wireguard from the kernel (Installed the app from https://f-droid.org/en/packages/com.wireguard.android/ to check, should say "kernel" instead of "userspace"):
    View attachment 5797043

    So my question is: Does this new release' kernel have wireguard enabled? If not, is it a planned feature? This would greatly benefit performance & battery life as far as I read.

    Thanks :)
    Kernelspace for wireguard is supported on LineageOS 20

    Users of this ROM, could you please tell if the ROM still has phone call issues like the last LineageOS ROM's?

    Went back to stock ROM after previous version of LineageOS gave call issues which i cannot daily this phone with main feature i can't compromise

    If so i'll need to find a custom ROM without call issue that's all i ask

    No points of updates if one of the main features of a mobile phone is broken
    Echoes only seem to occur on some devices (possibly depending on factors such as hardware or provider, but no one seems to have been able to narrow this down yet). I think you can only find out by trying the current rom yourself. In my case, unfortunately, there were echos that were not acceptable for my phone call partners, which is why I continue to use LOS 16. Fortunately, Exodusnick still includes occasional security updates in his builds based on LineageOS 16.0 with microG, so at least the security risk is addressed.

    Maybe the target sdk of your app? LOS20 is SDK33.. sometimes compatibility for older apps is depends on rom support.
    How can i check the sdk of the app? The app has no problem on android 13 on different phones and on different roms, like pixel experience.

    * Your warranty is now void.
    *
    * I am not responsible for bricked devices, dead SD cards,
    * thermonuclear war, or you getting fired because the alarm app failed. Please
    * do some research if you have any concerns about features included in this ROM
    * before flashing it! YOU are choosing to make these modifications, and if
    * you point the finger at me for messing up your device, I will laugh at you.
    */

    Working:
    - Wifi
    - Sound
    - mali drivers

    - Charging with device powered off
    - Stuff I didn't test yet
    - Camera
    - GPS
    - Fingerprint Sensor
    - Mobicore
    - SW codecs

    Not Working
    - Storage Encryption (WIP switching to FBE from FDE since FDE was removed in 13)
    - Network trafic monitoring (WIP, same reason as bellow, uses BPF)
    - 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
    a) Logcat
    b) proc/last_kmsg (or proc/kmsg)
    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
