hello guys, i'm having two serious problems with my mi9t / k20, the problems are phantom touch and i can no longer use the original rom, after trying to fix the touch ghost with the device rom change through twrp, only I had a surprise when trying to put the original rom back, because it doesn’t read any more sensors on the device if I put others like the pixel pixel or something like that it runs smoothly but miui doesn’t read anything from the proximity sensors or the like can someone help please, about the touch ghost i came to the conclusion that the factory is the problem is in the components and i already settled on nn having money to fix it, i just really wanted to be able to use the miui again and sorry if something got inconsistent and i don't know english and google translator are doing this translation for me, thanks to everyone for your attention.
