Faulty touch function after replace.
A used and smashed iPhone 4s has come to my hand. I have tried to repair it but i have met a couple of difficulties.
1. I got my replacement screen and tried to plug it in before i installed it completely. When i did that i worked perfectly. Then i moved on and installed it completely, but now the touch function doesn't work at all. What can be wrong now?
2. How does the vibrator connect to the motherboard? I am not sure it is working even though i just replaced it. When i turn sound on/off (by flicking the side button) no vibration occur. Is that something i have to turn on?
3. How does the loudspeaker connect to the motherboard? I am not sure it is working even though I just replaced it. When i make the iPhone read the screen out loud (3 clicks on home button) there is no sound, what to do?
Hope to hear your answers :-)
Is this a good question?
