Front and Back camera not working after drop

Thank you for checking my post

A few weeks ago, I dropped my phone to a ceramic floor, back side first. After checking the phone, I noticed that the front and back camera wasn't working along with the flash LED.

A check with the Diagnostic menu reports:

1. Rear camera not connected

2. Front camera is blank (No picture but detected by system)

Can this be a camera module problem? What I'm worried about is that some people said it's a hardware problem in the phone's board, however I haven't checked it yet...
