I did a thorough surgery of mine today. Ppl couldn't hear me at all, so I had to get to the logic board.it was not challenging at all. One has to be careful with the antenna area so as not to apply to much force thereby damaging it. However,if u couldn't clip it back,just use a paper tape to hold it down b4 placing the battery plate on it. I recoupled the phone and everything work excellently. Ppl can hear me clearly now
