Chosen Solution
I am looking to purchase this iPhone for 110 dollars, because I believe, per the description, all that should need to be fixed is replace the screen and the front proximity sensor, correct? Please see the device description below. The device has a cracked front glass, but there is no LCD damage to the screen underneath.
During a phone call, the device’s user is unable to hear the other party when holding the phone against their ear.
The front camera (commonly referred to as the selfie camera) is not operational.
It could be just the front facing camera flex also known as proximity flex. There is also a common issue with the 7 series phone that causes no audio due to having a fracture under the audio ic. I would be careful with this purchase
