iPhone 4 loudspeaker not working after screen replacement
i recently changed my iphone 4 lcd screen and everything is working fine except for the loudspeaker and also when i try to watch youtube clips or play music there is no noise at all, i dont know what ive done wrong ive connected all the connecters and such i cannot figure out the problem. i can make calls and hear people talk and they can hear me but, so the microphone is fine. but when i get a call there is no ringtone or anything. any help will be greatly appreciated, thanks
Is this a good question?
