After Android 11 update.

[sainathkishore12]

After android 11 update in my phone I'm facing weird problems like unable to answer calls, unable to hear voice, and fingerprint sensor moved up to the screen. I don't expect this from Samsung, my question is do you now how to make the os for Samsung from Android core? If you peoples don't know please learn that and sell products.
