Wave over the device while it's asleep air preview uses the proximity sensor

What's Under There/

So recently I was getting a close look at my vibrant. If you look about 1/4th of an inch to the left of the edge of the ear piece you will see two dots of what look like a front facing camera and an IR diode. So what are they?

Peep holes for your landlord.
They are proximity sensors, so the screen can turn off when your phone is next to your face while on a call.

What are these other sensors for?

By the front facing camera there are two other holes/sensors what are these for? Sometimes at night I can see a faint red light from the far left sensor.

Screen on app

I use my tablet a lot for taking notes in class and currently I just have the screen stay on. Does anyone know of an app that well turn the screen on using the camera similar to the one that uses the proximity sensor so I can save some battery?

Click to expand...
Click to collapse
And how can i do this? Thanks
The 3rd party apps are not very effective in darkness since they rely on the proximity sensor rather than magnetics. Not to mention battery life will be affected with the proximity sensor working all the time.
Yeah that's true. But Gravity doesn't affect battery too much. You can switch off all the other sensors and only keep the proximity one on for the book cover.

It's quite easy. The instructions are rather clear. I'm sure you can do it yourself
