DescriptionPower On Indicator simply flashes the device LED slowly, letting you see at a glance if your device is powered up.
This application was written to overcome a hardware design fault in the HTC Desire. When the Desire screen is off, there is no way of telling if it is powered on or not. The only way to switch on the screen is to press the power button, which boots the phone if it was off. This frustrating sequence led to a lot of accidental boot ups, and popping the battery out of the back of the device.
By blinking the LED, this app allows you to be sure your phone is on or off.
Control of hardware is always problematic. The following issues have been found.
1) Not all phones support the settings provided. For example, the HTC Desire will always flash green once a second when activated. This is due to an HTC firmware bug.
2) On some devices, pulling down the notification bar may stop the LED flashing temporarily (about 3 minutes).
3) Some notification customisation apps (eg Light Flow) take aggressive control of the LED, which Power On Indicator cannot overcome. Try disabling that app or switching off any "Direct Mode" controls they have.
I have decided to start compiling efficacy reports. More always welcome. Please let me know rather than giving 1 star. It's a very hardware dependent app!

*** Task Killers
If you use a Task Killer, you should exempt this app. It doesn't run in the background, but it sets timing triggers which Task Killers kill off.
