Waking from sleep, sleeps again

[Grolubao]

Hi all,
After updating to ios 5 I'm having this issue that when I wake the iPhone sometimes it goes to sleep immediately afterwards so I need to press again.

Is anyone having the same problem?

Using the power button on top? Yes, I've noticed this several times, not with the Home button though.

I do remember experiencing it a few times on my iPhone 4 but haven't yet on my 4S.

Yes, only with the power button. It happens to me a lot...
