Went exactly as I expected.
Sent to Tesco Mobile for their engineers to examine. Their stance is that as Sony hasn’t notified them of a fault then it must be accidental damage. Not really sure why they asked me to send it in, unless maybe they thought they’d find a massive dent in the frame and could say told you so.
Sony said I can send it to them for one of their engineers who will go through the same process and tell me the same thing then charge £21 to return the phone. As you said bigphil they deny any fault with the product even with numerous instances.
Tesco Mobile wanted £124 to replace the screen. A local shop wants £60 but their reputation is not very good.
Does anyone know a good repair shop near Halifax?
