@flohack Hello, Last year I had to reinstall Android for some months and I used LineageOS. This Android version allows you to run the selinux commands without the need of Magisk. It allows you to run adb shell commands as root with a simple checkbox in the developper settings. I was happy to discover this possibility with LineageOS as I had already restored my data on the phone

ignore my last reply, i got it to install. i tested it for a bit with at&t in the usa, and i found that 4g data works, sms messages do send to the person on the other end at first but on your end its just stuck loading and you cant send anything else nor receive anything else, volte calling doesnt work, it immediately fails on your end and when someone tries to call you they go straight to voicemail. location services seem to be faster than the halium 9 port, and cameraservice crashes whenever you try to record a video.

@sixwheeledbeast said: To me this seems like something that should be included into a toggle on the Battery pull-down menu itself, much like most modern devices have a "low power mode". How feasible would a toggle option to disable all these power hungry features and set the radio to the most energy efficient available in your location. Then toggling back would restore what you had previous. It seems like something the OS should provide and not additional apps. Something like this is already implemented in the OS. It is called "Flight mode" Humour aside, I don't know if it is really worth implementing switch for turning off all but 2G when it can be done in two or three clicks. But if you want to contribute to Ubuntu Touch this way, you can take a look at how it is implemented in lomiri-system-settings repository.
