KnockOn - Tap to wake or lock

Great idea maybe needs updated for LCD TOO !

This app is probably great for tap-to-sleep, but with tap-to-wake the screen stays powered on and black until you tap. App notifications appear on screen when it's in this state. So, this thing will eat your battery up. Looks like the real solution is to root the phone and install a custom Android kernel.

Locks fine and does the purpose but not effective enough. Once you tap the screen to switch off, the screen simply turns on n shows the lockscreen every now and again without the mildest touch on the screen n as a result drains the battery. Need to improve on the wake up option to make this a good app.

I know my phone model is not popular but I still want to point out that the app works very well, makes my phone feels like my old LG G3. This feature is almost a must for those have ever used it. Your app is very efficient, thanks.

To the developer, I noticed after a few times the app will stop working. I will have to manually press the power button on my Note 5 to wake and press it again to sleep, then the app will work again. So some bug fix is required here

People,beg u not to install its pathetic app.its some kind of a trap..it almost destroyed my brand new phone. it kind of hacked my phone for a moment.i wasnt able to do nething. even the touch didnt work..i cldnt even uninstall d app directly.. later i manage to kick out dis app from my phone. Beware guyz,ur phone is valuable

It works like a charm on my Lenovo Vibe K5+. Installed it and after proper accessibility permissions in settings it creates a simple off shortcut and also enables double tap to wake up on lock screen. A must have feature for all those who wish to save the power button of their devices. Before this I was using wireless Usb mouse to awake the screen !

Annoying... I downloaded bc it advertised triple tap... actually doesn't (have to pay to unlock it). All it had to do was specify which settings are pro like other apps do in Description to save ppl like me the time and effort)

those people complaining about battery drain please read through the sentence again. it is meant for amoled display for double tap to wake because anoled doesnt consume power when the display is black..other than that it is a great apps but sometimes scrolling too fast might cause double tap to sleep

I'm a bit disappointed that I can tap on lock screen to turn on. Also when I'm on Facebook and I double tap it turns off my phone

whenever i used to chat on messenger it automatically locks down while typing..this doesn't work for bubble up apps..

So I was trying to set up this app and on tapping 'start the app' I got this dialogue that says "Please allow KnockOn to access apps data in android security settings" and its not going away so I am locked out of my device and don't know what to do. Care to explain?

This has pretty much ruined my phone. Everytime i attempt to Uninstall, android force closes. Have to format my phone just to remove it

Needs support for AOD. Turns it off on my GS7 Edge. Maybe there is a pro setting for that, but I'm not sure.

Installed the app on Pixel and it works with the fingerprint scanner.. My question is When I double tap to turn the screen off the screen goes black but the three buttons at the bottom of the screen stay on for 10 seconds then goes off. So it appears that the screen is going black then off after 10 seconds. If this is the case, and can it be fixed to truly turn the screen off without just going black and the bottom button delay?

It is a bit troublesome for Galaxy S6 and later version of phones, especially because of the latest update. Those who have fingerprint unlock enabled cannot use it anymore because of a new security policy feature that happens when you lock the phone using a third party app like this. It would be great to bypass this security policy so that we can use our fingerprint to unlock after locking using this app.

Your app didn't work after update my ph samsung s6 edge. Plz check your app and reply me.

Stops responding as soon as I activate this app as a device administrator. Can't uninstall. Useless. Asks permission for drawing over apps and an OK button appears and from this time, the phone stops responding. Useless.

Unfortunately, this doesn't work well with the keyboard. It works well otherwise, but isn't active on the lock screen (where you'd type in your password or enter in your secret pattern or whatever).

Before this app was good. But after update app is no work. When I do install and go to the give permition page then my phone is tightly hang.. I sad,cause it is not work my phone..

App is ok. On a galaxy s8 the top and bottom part of the screen don't go off that fast. Mabey cause the display is taller than usual. Please fix

Worst app ever. Don't download this it messed up my phone

Wow. I was just setting up the app and my whole screen became unresponsive. What a mess!

Even though my screen isn't OLED type.Other apps use too much power.My phone is HTC One M7.

Great app. Works okay with note 5. I notice that i have to knock 4 times just to wake it up. Maybe if it could fix that then it would have more rating.

My mobile's lock button has damaged then i installed this app. Very very very good app. U must use it. I trust this app

Doesn't sleep on double tap, or to wake. I had to slide upwards and make samsung pay wake the screen. Galaxy s7 edge unroot. Fingerprint works. I noticed device admin keeps turning off for this app. That's probably why it doesn't work

Love it ,it works .running Miui rom all the sensor types dont work very well ,good work & your ads are subtle .
