Chosen Solution

The screen of my phone broke because it fell down. After replacing the screen now the iPhone has the following problems:

  1. proximity sensor does not work
  2. front camera does not work
  3. earphone does not work (I can only use speakerphone)
  4. Touch ID does not work.
  5. I notice the upper part of the phone heating I opened again the phone and repeated the procedure but the same problems persist.

Torn front camera flex. Home button cable and or metal plate cable may be torn as well. I would start off with replacing the front camera ribbon cable then the home button metal plate.
