Chosen Solution

The phone needed a screen replacement. After putting a new screen I realized there was a tear in the camera ribbon cable in which I put a new Camera Strip inside the phone. The plate over the speaker and Camera Strip gets very hot and neither the speaker nor the front camera is working. Any ideas?

If the earpiece speaker bracket is getting hot, this may be the case of a defective Front Camera and Sensor (FCS) cable or Earpiece Speaker since the speaker and the camera are not working. I suggest testing to see if this is the case by transferring these parts over from the old screen assembly. iPhone 7 Plus Front Camera and Sensor Cable Replacement iPhone 7 Plus Earpiece Speaker Replacement
