iPhone 4 logic board loud speaker is distorted
The loudspeaker (as in the bottom speaker) becomes distorted when the volume is raised further than half way, I put the logic board into a fully working iPhone 4 and the same thing happened so the problem is definitely in the logic board (btw I have been in and out of my iPhone about a 100 times as I like to change the screen colours) I'm not really sure how to fix this but hopefully you guys can help as I'm planning on selling my phone as I've ordered the 5s! Thanks for your help, Nick
