@Verevka Thank you very much for porting Ubuntu touch, for sagit, which makes my old phone have a new idea, there are some problems in my current use, simcard has been showing that I am searching for operators, resulting in my inability to use cellular network, I used Android 9, Android 8 is the same situation, and the bottom of the phone button can not return, multitasking and other operations, I hope you can take the time to fix it, thank you!
