My boyfriend cracked the screen on his Stylo 6. The phone wouldn't respond correctly to his touch and the notification bar would slide down on its own. He threw the phone, it hit the wall so hard it left marks on the wall. I changed the front lcd screen, back panel and the frame. The phone is still not responding correctly. Would changing the motherboard fix it? I don't know what else I could change. Could he have damaged the motherboard and would that cause it to glitch? I love the Stylo line and don't want to throw it plus I don't have the money to buy a new phone. What else could cause the glitching? Could I have bought a bad screen? I know I did the repairs correctly. The phone turns on and I can use it but the bad touch response has me wanting to throw it at the wall too. What else can I do? Help please!!
