Xperia SP Display Problem!

[Saddamjit]

When i press power key the diaplay turns grey and no home screen is displayed .

again i repeat pressing power button to get wallpaper screen.

Sometimes when i recieve call nothing is displayed on screen except grey colour. No name of caller or number is displayed.

I went to service center but they failed to find solution.

That's odd, what if you reinstall the latest update?

Update Service (SUS)

PC Companion (PCC)

Bridge (for Mac)

its a software glitch hopefully would be sorted in the upcoming 4.3 update 

[Tejinder]

Yeah, I hope that too. No repair can sort this out but an update might be able to.
