Power On Indicator simply flashes the device LED slowly, letting you see at a glance if your device is powered up. Note - most Android phones will not let any LEDs flash while the screen is on, so turn your screen off to see it work.

--

This application was written to overcome a hardware design flaw 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 to stop the load sequence.

I wrote this app to blink the LED allowing you to be sure your phone is on or off.

***

Thanks for using Power On Indicator! I hope you find it useful. I must point out though, controlling phone LEDs is very difficult for software developers. Often there are reasons why the LED won\'t blink in ways I cannot fix. For example:

1 - You must exempt this from task killers or it won't work for very long.
2 - On most Android phones, all LEDs disable when the screen comes on.
3 - Not all phones support all settings. For example, a hardware limitation means the HTC Desire will only flash green once a second.
4 - Dragging your application's notification bar down disables all LED flashes for a minute.
5 - Enabling Direct Mode in other LED controlling apps will interfere with it.

Thank you everyone for your positive feedback!

I have decided to start compiling efficacy reports. More always welcome. Please let me know rather than giving 1 star.

    Apapun Rom nya, aplikasi ini akan selalu saya install di Xperia Mini Pro (XMP) saya. Dengan aplikasi ini, led di XMP saya bisa di setting untuk menyala berkedip terus seperti led pada hp Blackberry.. Terima kasih Developer, ini aplikasi yang sempurna

    Works for a little then always stops working if at all on my Samsung S3 & S4. Such a shame because thr is only a couple of apps like this and all are dumb or faulty. Also needs to be dimmed slightly because it might fry the light. WORTH FIXING THIS APP AND COULD MAKE GOOD MONEY IF WORKED SO PLEEEEASE FIX!

    I downloaded it about two months ago. And i was really impressed with it as it did what it promised to. But before a month it stopped working.

    Just needs an ability to select a custom color. Then it'd be brilliant.
