ScreenWakeUp

ScreenWakeUp uses the proximity sensor to lock and wake up the screen. It run as a service and it will restart automatically on boot.
WARNING: BEFORE UNINSTALL YOU MUST RELEASE THE LOCK ADMIN! (run ScreenWakeUp and select on RELEASE LOCK ADMIN)

You can lock the screen with ScreenLock application (it's not a widget), a long press on search key, covering the proximity sensor on the top of the phone for a few seconds (settable) or simply you can put the phone in your pocket (I've noticed it can fail if the tissue of pocket is opaque black, I think due of how the proximity sensor works).

The screen automatically wakes up (or unlocks if enabled) when you take the phone out from the pocket or you move a hand over it.

The program is event driven (don't uses CPU cycles to check sensors), but the phone needs to stay in PARTIAL_WAKE_LOCK mode to permit the wake up. The CPU doesn't go into sleep mode, so after a few minutes (settable) the lock will be released to prevent battery drain. You can read more about PARTIAL_WAKE_LOCK here: http://developer.android.com/reference/android/os/PowerManager.html

Don't be afraid about consumption of proximity sensor, it's really low (0.045mA on my atrix).

Permissions required:
- WAKE_LOCK for turn on the screen
- DISABLE_KEYGUARD for unlock the phone automatically
- MODIFY_AUDIO_SETTINGS for check if a headset is connected
- RECEIVE_BOOT_COMPLETED for restart automatically at boot
- VIBRATE for vibrate on screen lock

No internet connection needed, no ads, no privacy risk.

Known bugs:
- Sometime the auto unlock option don't works
- Sometime the proximity sensor stops to work when the phone is connected to PC (you must restart the phone)

I use a Samsung S5 and A7. I bought a dot-view cover for the A7 from Amazon and it was bundled offer where I got a stylus along with it. Actually was not aware that these devices had a stylus that could be bought. Then I got accustomed to using the stylus and using the hard keys required the use of fingers, so I started looking for apps which could substitute hard keys. First was the home, back and recent. Then came the need for screen lock and wake. Tried apps, all failed, only this succeeded 👍

I'd like to see in a future an option where I could choose for how long I want to suspend the service by tapping the notification in the status bar (when that option is selected). Right now it can only time out for 5 min and I think it'd be a good idea if the user could choose between those 5, 10, 15 min and maybe an "undefined", where you'd have to tap the notification again to activate the service back.

Marshmallow Samsung Note 4 with Samsung ROM here: To avoid on/off loop until screen unlock don't deactivate auto lock screen. Also I've detected another small bug in the settings, if you set up the notification tap to lock screen, you'll lost the ability to access to the app settings, even on the drawer icon (it will lock your screen) so you have to unlock the admin lock manually from phone settings to be able to uninstall and install again to regain access to the settings. It used to work fine on Kitkat so I guess that has to be a compatibility issue.

Great app. Saved my phone cause the power button soon stopped working and they (phone company) want to take the phone for four days to fix it. Like I don't have to make calls during that time. Thanks for making this app

my first I thought this Apple is good however I uninstalled it because it kept waking itself up. It is way too sensitive. HTC DROID DNA W/ built-in battery. One of the first to have a built in battery phone is very good. still working after over two 2 years.

Great application.. As am using a flip cover over my phone, i dont have to press the power button again which was about to die by my presses.. Thanks a lot devs.. But i had seen a slight battery drain.. Hoping that devs can fix that soon.. Then will give 5 stars.. <3

Thank you very much for this FREE app! It works very well on my MI3 device. Very well written with great fine-tuning options and settings. I believe every modern smartphone should have (at least) a way to wake up without using a physical button. Mechanical parts get broken easily. Having said that, a solution should not consume unnecessarily big amounts of battery power. I think this app excels in that area as well. This is for those who are looking for a good way to have that 'double tap to wake' feature on their devices but don't want to strictly 'double tap' away, for folks like me who simply just want not to use that physical button every time. 5 stars for iiizio, good work!

I've tried autowakeup on 2 devices now and both have never turned on the screen. No other apps are running to interfere with it. I even set the timer to 1 second and suspened the delay but nothing.

I needed a way to turn on/off my phone after the power button broke, and this app is perfect. I use the default proximity sensor to double-tap my phone off. The screen automatically turns on briefly when I take it out of my pocket, which is so convenient. My user experience is now better then before the power button broke. I recommend this app even for phones with functioning power buttons. Thank you!

1. Screen automatically starts after lock. 2. App consumes so much battery, my phablet has 3500mah which works for two days without app but after installing it works just for 7 to 8 hours. Fix this issues.

With only the most required options and no other fuss, no big bug found as of yet, doing exactly what it is created to do, it is by far the BEST Lock Screen app as compared to even the hyped paid apps! Recommended to all like me who hate to press the power button and then also swipe to unlock. After a recent update on my Note 3 the 'None' option disappeared from my lock screen options. This was the last app I tried and it actually turned out to be the best! Dont go for any other paid apps. Thank U Dev!!

excellent app though takes a toll on the battery if proximity is set to always on,thanks guys keep up the great work.

Pra. D. Jul 16, 2015     

I use my phone with flip cover. I enabled this app. When i open cover phone wake up automatically. This make my phone more practical and professional thanks developer for developing amazing app.

Alcatel Idol X+. Some time the app worked fine. Later I noticed it started waking up every 7-20 seconds, no matter during a day or night. It's annoying. I'd like to keep using it. Is there any setting that may fix it? I'll set 5 stars if fixed.

Roh. S. Sep 23, 2015     

I have tried so many similar apps before this..I can tell, this is by far the most accurate,light and simple app.I am impressed.

daa. z. Mar 9, 2015     

Great for me, but i guess it took up a bit memory (ram). Perhaps low ram phone should think twice to use it.

Aus. S. Dec 16, 2015     

Some issues with the screen turning off accidentally. Would be great to incorporate the accelerometer in addition to the proximity sensor(s).

Ela. M. Jul 31, 2014     

Tried many apps to wake up screen..none worked.. This is the only working app got my requirement fulfilled.

A. G. u. Mar 1, 2014     

Worked great for a while, then after an update just hovering a finger an inch away from the proximity sensor shut off the screen. Had to uninstall.

Jil. M. May 5, 2015     

With the on/off button in a stupid place in my phone it was driving me nuts not being able to tap to see the time. This is perfect - flip the cover (or briefly cover the sensor) and it wakes up enough to check the time and notifications but doesn't unlock the phone which is exactly what I wanted! The only downside is it doesn't work in a darkened room to check the time during the night, but that would be the nature of the proximity sensor, no fault of the app. Five stars and thanks so much! :-D

Only just started to use but the timer doesn't work. No matter what I set to up 30 secs, still goes off after only 9! Just dropped to one star cost now the phone just stays awake. uninstalling!

Very functional. It works even on my gingerbread phone (Motorola Defy Pro). I like it so much that I installed it on my Huawei Ascend G6. I'll observe how it behaves on my phone. Hopefully it will do well.

Did not do what I thought it would do but I actually found it to be better than what I first wanted. I thought this app claimed to turn the screen on when I tap the screen while it was off but it actually makes it on when I pick my phone up from being upside down or take it out of my pocket the screen turns on automatically. Absolutely brilliant.

Not of use. Just rubbish. Instead of touching the app to lock screen, we can activate autolock or use the lock shortcut. Not useful to unlock screen.

Bru. S. Mar 7, 2017     

Great app. Exactly what I was looking for to allow me to easily and quickly check my notifications when the phone is flat on the desk. So far so good. Thanks.

Kri. Z. Jan 28, 2016     

Using this app on lollipop is fine. But when smartphone (infinix x510) upgrade to 6.0 the screen always wake up soon when display not active

Iva. F. Sep 18, 2016     

Well...its ok but needs to be tweaked. Why dont you copy funcionality from phones like oneplus that already has this feature. And its bad that it locks phone while watching video on youtube.
