8900 keeps going into standby

[jakesorge]

Hi,

I Recently had my T-Mobile blackberry unlocked for my wife to use. It is now on Virgin. I have upgraded the software and everything is working well with the exception that the phone keeps going into some kind of stand by. It isn't the normal keypad lock, the unlock button wont unlock it, you have to press the red power button for a few seconds to wake it up.

It appears to be on a timer as it locks after about 2 minutes and goes to a black screen. It will happen in the middle of typing a text or whatever you are doing and when you press the power button to unlock it, it then takes you back to the home screen.. Very annoying!

If the phone rings you cant answer it as you need to press the end call button to unlock it before you can answer!

I have gone through all the options and cant find anything to stop it. The auto on/off if off. Password is disabled with security time out set to 30 mins.

Any help would be appreciated

Thanks

UPDATE...

After trying allsorts of stuff it seems that it wakes up after pressing any button for 2-3 secconds, not just the power button..

Managed to sort the problem by roling back the software to version 4.6.1

Thanks for all your help

My phone does exactly the same - the phone has been replaced twice for this problem ! How do you roll back the software.
