Please try out the lite version at first to see if your hardware LED works (on screen LED is always working!).

Please check device specific hints at the end!

Fast support is very important for me! (Look at the ratings, thanks to all people!)
If you have problems please do a full re-install and/or reboot your phone.
Otherwise contact me at Facebook or Email to get help.

Warning: If your phone speaks after install (Samsung S4, SIII, S3 Mini, S2, Note1, Note2, Note3, LG Nexus 4) you have to disable Samsung TTS (text-to-speech) under settings -> apps manager -> all (on the right) and Google TTS (text-to-speech).
Only needed when you use the accessiblity service!

Another solution to fix talkback issue:
You can change the launcher by using another one from the Google Play Store. For example, Solo Launcher - Swift & Smart, Nova Launcher, Go Launcher and Holo Launcher. These launchers will not exhibit this bug.

For Samsung S4 users: If your phone speaks when opening your browser you have to use another browser like Chrome or Firefox.

Hint HTC users: Your phone is NOT supported, you have to use the on screen led!

Sony Phones: Please disable stamina mode in your device settings.

Let your led indicator glow with different colors!
