Hello, can I use the Rom for the Samsung Galaxy Tab A T-590 (2018)? If so, which version should I take.
Thank you very much.


Apr 27, 2022
Flashed the 3.0 version last night on my Samsung note 10 Snapdragon. Everything seems to work fine.
However the icon shape is a bit buggy. It won't apply a white border to unsupported apps like before, it'll just give up modify it so now many icons are in different shape......

I did a clean installation of v3.0, and the problem mentioned above appeared. However, after rolling back to v2.1 then update to v3.0 again, the problem no longer exists.

Edit 2:
After I change the size of ui (in v3.0), the problem appears again. So I think there's really a problem with v3.0

Many thanks for your work, it works like a charm, with Bluetooth and so on. I had to install F-Droid for the others stuff, like a cam app'.
Very smooth and pretty cool.

    I run this GSI on Xiaomi Pad 5, I found it doesn't play audio properly, how to fix it?
    And, when plugging in the headphones, it does not respond.
    Go to Settings -> Phh Treble Settings and:
    Fix distorted audio: Qualcomm features -> tick Use alternative audio policy and Disable soundvolume effect
    Fix headphone jack: Misc features -> tick Uss alternative way to detect headsets
