Also, very very important! Encryption does not work... please add it to "what's not working". Will you fix it please as it poses a security threat especially in recovery where data are unencrypted?

screen brightness is fully increased to scan fingerprint. Can't the brightness increase locally as in stock?

Samsung Galaxy A51
Hello! I flashed this on my A51 phone not too long ago, but today I came across a bizzare issue. After leaving the phone on for a while, I found the screen dimmed with the LineageOs working logo on screen. Pressing any button didn’t seem to do anything and the only way to get the device out of this “state” was to fully restart it. Is there any way to fix this?

Awesome stuff, really !!
Can someone who already installed the March build check whether the phone encryption is working? This is the only criterion for me really :)

    LineageOS is a free, community built, aftermarket firmware distribution of Android 13, which is designed to increase performance and reliability over stock Android for your device.

    LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

    All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review. You can also view the changelog for a full list of changes & features.

    What's working:
    • RIL (Calls, SMS, Data)
    • Bluetooth
    • Wi-Fi
    • Camera
    • Video Recording
    • Video Playback
    • Audio (Record and Playback)
    • Sensors
    • Flashlight

    What's not working:
    • VoLTE (Blame Samsung for that)
    • FOD working only on highest brightness Now it's functional
    • Camera HAL3 and 48MP back camera, this is due to Samsung's extension to camera HAL is not recognizable by AOSP (Again blame Samsung)
    • Feel free to report any issues you may encounter with relevant logs

    • To use MTP as default, enable developer options and choose file transfer as default mode for usb configuration
    • Only for A51 4G variant, 5G has different SoC therefore not supported

    Hello, is there any possibility that this rom will be ported to the official lineage operating system in the future? I am grateful for your support for our device.

    Screen flickers when you put it to your ear during a call. There is no such problem on GSI firmware. sensors are OK

    UPD:
    Hover proximity value near the ear

    I've been looking for a few days now how to set up this sensor

    Does anyone know what config file is responsible for this?
