Have looked through the forums and also on the net and haven't found anyone with a similar problem yet but basically every now and then my screen stops automatically turning off and locking the phone and it basically then stays turned on in a dim state. I also can't press the power button to turn it off myself but can do a soft reset and everything is fine again. I've only had the phone 3 days and I've only seen it do it twice today funnily enough after I changed the lock screen timeout from 1 minute to 30 seconds. I have since changed timeout back to 1 minute and it's still working and I'm waiting to see if it happens a 3rd time or more. Also phone was fairly flat at the beginning of the day and so it's been on charge connected to a PC most of the day (because the PC charge is so damn slow) so not sure if having it on charge connected to the PC has been a cause. Anyone else seen anything similar? If it keeps happening hopefully a firmware update will fix otherwise it will be back for repairs.
