BrightTooth

This app is made for fixing a little issue for users that saves battery life by setting brightness mode to manual with a low value.

I do it too (I have a Nexus 5), the problem is that when i get a call when i'm in my car and it is daylight i can't see anything on the screen and then i have to start messing with the phone while driving....NOT GOOD !!!

This is why i developed this App.
This App detects when your device is connected to your car bluetooth and then switch brightness mode to AUTOMATIC, when disconnecting from the car's bluetooth it switch it back to MANUAL with the previous value.

All you need to do is selecting a bluetooth device to look for and hit the "Start" button.
i'm using it for a few months now and had no problems at all.

This App will NOT effect the battery life at all !
