iphone 4 - phone is on but screen is blank

Rotor

Hi, as the title says, daughters iphone 4 screen is unresponsive, but phone still rings when called.

It hasn't had a bang (that she knows of) but she accidently deleted an app, she locked her phone and screen wouldnt turn back on again. It can receive calls but she cant answer them or reply , because the screen wont turn on.

Any ideas? Or is it a repair job - if so , where should she go for repair?

Thanks

Press and hold the home+sleep/wake buttons for about ten seconds (keeping hold of them for longer doesn't do any harm) until the phone reboots.

It might be hard to tell if the phone has rebooted if the screen is broken, but if it's not the screen and just a software problem, you should see the Apple logo come up when the phone restarts.

My 4S did this too this week, a reboot solved it.

No probs

That's the way to do a 'hard reboot' which bypasses the software, so if the software is acting up this is the best way to restart.
