I bought a cheap iphone 5s with a big spot on its screen so i replaced the screen but apparently it keeps restarting after using it for few minutes, if i just leave it then it dosent restarts but as soon as i use it or lets say i open hotspot or on a call its restarts. So far i have changed everything i bought a locked iPhone 5s and put my motherboard in it but it still has the same issue. I also gave it to a guy he worked on it but it still has the same issue . Can someone help me i just dont know whats the problem. When i bought the phone it was fine back then this problem happened after screen replacement. My new lcd also has touch problem it works randomly but its a faulty screen. Thanks
Sometimes if you put the wrong size screw in the wrong place when replacing the Lcd it damages the track that causes this issue. Before it was worth spending time and money repairing the track but Iphone 5 which is now being discontinued and cheap to purchase does not make any sense. Hope this help
It sounds like your battery is overheating witch may have caused the faulty screen and the phone to restart. Did you ever try replacing the battery? If not that sounds like it would be the cause. By the way on the first screen where was it not working?
