Hey guys, I have been having a problem with my Xiaomi Mi2S lately. First of all, I broke the screen (cracked) so I ordered a new one on Ebay. My friend then changed it and it worked perfectly. After about 2 or 3 weeks, screen started doing this weird thing that it doesn't respond. To clarify, when I turned my phone on in the morning, it was responding without any problem, like it should. But once I locked it (using the power button) or let it go to the sleep without pressing the button then when I wanted to use my phone again, I pressed the power button, screen turns on and says I should swipe it up, it doesn't respond to any touching. Not even those 3 buttons at the bottom. The only solution was to force restart the phone (holding power button for some time) then it worked again, but only until the moment when I locked it (sleep mode). I reinstalled MIUI with my friend and updated it to the latest version, it still didn't work. I then left the phone at my friend place cause he told me he would try to make it work somehow...he let the battery drain and after few days, tried to turn it on and it worked great again. I got the phone back and it worked for few days, then the problem came back. It usually worked, but sometimes I had to restart it...then it was getting worse and worse and started happening more often, so I had to restart it pretty much everytime I wanted to use it. Now it got to a point when sometimes it doesn't even respond after restarting. Before this problem started happening, I had a problem with the proximity sensor. When i called somebody, screen turned off immediately when I pressed the name in the contact list and when I finished the call, it wouldn't turn back on until the person I was calling ended the call. But I have no idea if it might have anything to do with the main problem. Does anybody have any idea what I could do in order to make it work? I will appreciate any thoughts or advice, thank you!
