Now after you accidentally drop your iPhone you should check the following to see if there’s any significant damage. See that if:

• The Display lights up
• The Touches works and gives back the proper response
• Has no colored lines or off-color spots anywhere in the display
• Has no dead pixel (no black dots in the display)

You should look forward to replacing your iPhone 6s display if...

• The phone has visible cracks but the touch still works
• The fall which damaged the front glass of the iPhone 6s doesn’t damage any other functions such as camera, speaker, or proximity sensor.
