iPhone 7 Earpiece not working after screen replacement
Hi, I am fixing an iPhone 7 Plus for a family member and after the screen replacement the speaker does not work. After some troubleshooting I found that in a press a little below the display it works. Well here’s the strange thing. If I record with the front facing camera I get a sound almost like interference or something similar but the audio is still recorded from the mic. Attempting to play anything from the earpiece you don’t hear anything unless you press just below it. I have already replaced the ear piece to no avail and want to try and find the source of the problem. I do know that the display my aunt bought was for the iPhone 7 Plus but as missing all the little pieces at the top of the display were missing. I am wonder if there’s one piece that puts a little but of pressure on the connection pins that makes it contact. Can someone please tell me what I should look for? I don’t want to send this phone back only partly working. While it can be used the person wants to use it as their main phone again.
