the build instructions from the wiki are very simple. it's just one command. meanwhile, the phone i actually use is a free government phone, and i'd like to see what the barrier is around using it with an open source OS. the factory OS has more advertisement apps than normal apps, and it takes a few minutes to respond to a touch. additionally it has some issue going on where when i touch it it may register the touch in a different spot than where i touched, making typing and swiping very hard, and i'm not sure how i would diagnose this on a closed phone. this free government phone has a unisoc chipset. it looks like there's a factory flash tool at https://spdflashtool.com/download/spd-flash-tool-r26-21-2801 . i downloaded the 'treble info' app on it, and it is treble-based, so an open source OS would run. i've heard these phones are locked, and that trying this fruitless. i'd like to learn the detail myself.
