Grey Screen - Xperia S

[lister]

I'd locked my phone and came back to it later on and as I clicked the power button a grey screen come up, I know the phone is on its just the screen won't display.

It has been 20 plus hours or so and I'm starting to lose my rag, how do I fix it?!

Also I have done the power and volume button thing so please don't mention it...

Hi and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.

If you have tried to force a shutdown by holding the ON/OFF button + volume up(+), I suggest that you perform a software repair via PC Companion to exclude software related problems:

In PC Companion you press start on Support Zone > Start on Update the phone/tablet software > Repair phone/tablet (the blue clickable link in the message) > Follow these steps without having your device connected to the PC.

Follow the instruction that appears in the program and do not connect your device until this guide tells you how to connect it.
