I pick up my phone, and the display wakes up by itself. I put it down, and the display sleeps. While the phone is there on the desk, a hear a notification. I just need to have a glimpse of what it is about, so I wave my hand over the phone, and the display lights up so I can do that without picking the phone up. This is not witchcraft. This is not a scene from Star Trek either. This is present-day technology.
Gravity Screen is an Android pp that uses the gravity sensor and other sensors on your phone to trigger off display actions. It is particularly useful if you have to pick up your phone often in the course of a busy day, or if you are using one of those monster phones and your power/lock button is difficult to reach. Running Gravity Screen on your Android smartphone liberates you from the usage of the power button.
The developer says that the app uses only 6% extra battery power, which sounds great. To keep the battery usage low the program turns on the proximity sensor only when it’s really necessary. Moreover, when it turns your screen off and the proximity sensor is covered it puts your phone into deep sleep state to save as much energy as possible. In my usage, I am yet to notice any significant battery drain.
The app lets you customize the sensitivity of the various sensors to tailor them to your needs. There is a free version which works well (that is the version that I am using), but also a paid version that unlocks more benefits to you (and I intend to upgrade to this soon). The app is available for smartphones running Android 2.2 Froyo and up.
