I thought I'd add few pictures of a recent iPhone 5 Screen Repair.
A customer brought in his Sons iPhone 5, it had dropped out of his pocket while running up their drive way and fallen onto the tarmac. The phone was still useable but small pieces of glass had started to come away when in use.
The impact to the screen was very close to the front camera and proximity sensor. Luckily both were still working fine.
After swapping out the screen module the customer picked up his sons phone looking as good as new. The customer was charged £120 and the repair was turned around with an hour.
