Hello guys, I just replace an iPhone 11 screen. Transfered the original Earpiece Speaker and Front Sensor Assembly to the new screen. Now the Earspeaker volume is much lower than it used to be. I have the problem during calls and when I try to play music with the speaker. Do you have any ideas what I could have done wrong during the repair? The front camera is still working so the flew cable is connected, could it be badly connected ? Thank you in advance for your help !
It is resolved. A thin plastic protection was still in place between the lcd and the earpiece, I noticed it once the phone was open again.
