I use a widget called No-Lock to do this. Works brilliantly: No Lock - Android app on AppBrain
Settings -> Sound and Display -> Screen timeout
just change the time to like 30 minutes. Should be long enough.
I have it sitting on my desk all day - 30 minutes is not the issue, I don't need to change the screen timeout, I just don't want it to lock when it does I installed NoLock and yes it does not lock when the screen times out so great, but unfortunately when I press the lock/power button is does not lock either - still Nolock is a great improvement bkkguy
Logically speaking, you dun need a lock screen at all for capacitive screen. Cause nothing is going to be able to trigger the screen other than your finger
, as it is really really annoying
