Recently my HTC One V has developed the annoying habit of having the screen dim within about 10 seconds of the time I wake it. A few more seconds and then it's off completely. I have adjusted the settings for SLEEP to be 1 minute and have tried 2 minutes. Doesn't matter, still get a dimming very quickly. Have tried autobrightness on and off. The widget KeepAwake has helped but I don't understand why I need a special widget to do something that the phone should be doing on its own which is staying lit. Any easy fixes for this frustrating problem?
