HTC Desire HD Android 2.2 disable screen shut off when timer is running I tried to use the timer for a countdown of 3 minutes. 1 minute in, the screen shut off and the phone locked, disabling the countdown. 

After 4 minutes, I realised what had happened. Is there a way to disable the screen shut off just when the timer is running?
You may try to install KeepScreen application from Android market and configure it to disable screen timeout when your timer application is running.
