Internal ear speaker not working after screen replacement

My repair shop has encountered a few issues regarding the front camera and proximity cable. There is the possibility that the original flex cable was stressed during removal or installation. There seems to be hardware compatibility issues, specifically with the iPhone 7 models, with some of the flex cables produced by third-party manufacturers, as we tried a flex cable from another supplier (it cost almost twice as much as our normal cables) but it solved the issue. I'm not 100% certain this is the same issue for you, but this has solved the problem we had with Cam&Proximity cables.

I know this is frustrating I have this problem now and I've had this problem before with the Home Button basically I replace the screen in the Home Button function would not work at all it would only let me go to the home screen or pop it up halfway on the homepage no matter what Home Button and I replaced it with screen it did not matter the home button function was not working again and I heard that has to be reprogrammed through Apple in order for it to work

I came across this same problem after replacing a screen on 7+

I tried and checked everything! screen, button, speaker and plugin earphones worked ok

only the phone ear piece didn't.

as crazy as it sounds this is how I finally got it to work...

• 1. go to settings, General, accessibility
• 2. Under "Hearing" turn "Phone noise cancellation OFF and "Hearing aid compatibility" ON
• 3. played a memo message and ear speaker WORKED!!!
• 4. switched the setting on step 3, back to default. phone still works!

I don't know why this worked but it did.

this was driving me insane! I've done lots of repairs

never had a problem like this.

hope this helps someone

Hey John

Sounds to me like your problem is related to the hardware not communicating with each other. When doing repairs you should always disconnect the battery and then drain the remaining charge by holding the power button for 8-10 seconds. After you do this you can change your parts without the Logic Board storing previous hardware information.

The Logic Board needs to reset on hardware changes, especially the new iPhone models since they have new chips and circuits. Your problem may be as simple as the Logic Board not recognizing your replaced parts correctly.

mine does the same. i replaces my screen and switched everything over to the new screen. when i powered my phone up the ear speaker the speaker phone speaker, the front camera and the home button doesn’t work. i used the original home button also. a few months later i cracked the screen and this time ordered a pre assembled screen with everything ready to snap back in besides the home button. i switched the original button to the new screw screen and i still have the same problem??! what did i do wrong!
