iPhone 5 problem with screen sensitivity during calls

 

In this post we will go over iPhone 5 problem with screen sensitivity during calls as well as other issues.  I will show you how to remove the speaker, camera/proximity sensor and microphone for the iPhone 5.

I had a client that was having big problems with her screen activating features when making calls,  here are the problems she suffered from listed below:

  • Speaker phone turning on
  • Hang-ups during calls
  • Touchpad visible during calls
  • Dialing numbers during calls
  • Muting calls

The phone is an iPhone 5 running iOS 7 up to date as of Jan 15th.
First of all, the screen was recently replaced, however, everything wasin perfect working order.

After troubleshooting the device I inspected the screen for anything that would obstruct the proximity or light sensor.

I thoroughly cleaned the screen cloth with a lens cloth and neutral cleaner.

After fully testing the device I could find no cause for the super sensitive proximity sensor and related issues.

I removed the camera proximity and microphone assembly and replaced it by following the steps below

I then open the screen assembly from the bottom using a thin pry tool and slide your thumbs around edge to unlock screen.

Slide it upward but be very careful not to allow pressure on the flex cables by opening too far. Next, remove the 3 screw securing the shield protecting the flex cables. The 2 lower screws are magnetic, however, the screw in the top right is not, therefore be careful not to lose it.

Next remove the flex cables with gentle upward pressure using a plastic spudger

You should then inspect the camera / proximity /microphone assembly and flex cable flat pry tool with a twisting not pulling upward motion.

 Now your screen can be safely removed.

Next, remove the shield securing the speaker down to the screen assembly with two screws.

Now you can safely remove speaker exposing the camera assembly

Now you can safely remove the assembly and microphone to inspect the sensor areas and looking for damage to the unit or the glass underneath it

Replace the component and fully assemble the phone to properly test
