iphone 5 is compatible with only a few 4g frequences. Depending on your service provider, it will be compatible or not with 4g. For instance in France, only Bouygues telecom can provide 4g for iphone 5
Hello, On iPhone 4 this problem occurs often when the screen quality is not good and the sensor filter on the screen lets too much light arrive on it. Did you try with the broken screen again to see if it doesn't come from the quality of the new screen ?
Try to plug the old lighting connector (no need to redisassemble everything) and see if the microphone works. If yes, the microphone of the new dock is faulty. Use another new lightning connector and it will be fine
Hello. Just a small question : Why don't you just buy a new screen assembly, and sell the glass and broken screen to someone who is used to change the glass only ? It won't be much more expensive but sooo simpler.
This topic is from march and we are in September... First, I really doubt this connector has anything to with the problem, if you know how to read. Second, I'm in France and I was looking for a bit of help, not someone to do it for me. And third, I gave back the phone to the client 6 months ago.
