Double tap to wake (no root required)

[bryanhayn]

I finally found an app that allows double tap to wake without root! Now you can keep your power and home buttons from getting all gunked up. See the attachment for the APK. According to the website below, this used to be available in the Play Store. I guess it was removed because Google doesn't like to allow apps to wake the screen?

Edit: Warning - app seems to use a lot of battery when screen is off

Thanks, but curious if this will be a battery drainer with wakelocks ?

I'm not sure how much it affects battery since I just found the app today. I noticed in the battery stats that the screen on time continues to increase even though the screen is off.

The app keeps the screen on so that will increase battery drainage.

Why don't you give Gravity Screen a try ?
It's one of the reasons to own an Android....

This WILL drain your battery. Guaranteed.

Why does it drain the battery? The screen appears to be completely off. I looked at the screen with a flashlight and couldn't see any pixels on. Is it preventing the phone from entering a low CPU use sleep state?

If it's keeping the screen on, but only displaying "total blackness", then any AMOLED display (such as on our Note 5 devices) will APPEAR to be completely off (as none of the pixels are illuminated) even if the display is still "alive." If the screen is alive, then the device isn't going into suspend (sleep), so it would destroy idle battery life. Instead of only dropping 1% (or less) of battery charge an hour, you'd start dropping 7-10% an hour.

The reason it uses a lot of battery is because it uses the proximity sensor
and it keeps it enabled all the time.

Same holds true for any of the double tap screen-on apps at the playstore.


Good luck,
Have a great day!

Unfortunate that you can't set a duration for it to remain active after the screen has gone off (e.g. 10 seconds, to use when the screen unintentionally turns off) so that it doesn't continue to drain battery. Anyone know of a non-root way to disable it after a given duration or another app that can perform this function?

Knockon Jawomo is great , why not LCD though?.. I want a double tap to wake simple one no adds! Must be a decent tap to wake out there for LCD
