About Screen Lock

Just one touch to lock and turn off screen.
The hardware power button of some devices is not well designed. The frequent use to power on/off screen may damage it. We provide the software shortcuts to replace it and extend its lifespan.

★ Different kinds of shortcuts (buttons):
- Display on home screen
- Display in the notification
- Float over other apps (floating shortcut)

★ Features:
- Adjust the size of floating shortcut
- Adjust the opacity of floating shortcut
- Built-in icon library
- Select icon from the pictures in your device
- Vibrate when locking
- Play sounds when locking
- Display weather information
- Floating shortcut can auto hide in the fullscreen mode
- Set floating shortcut to the desired position on the screen
- Floating shortcut can auto return to lock position
(In this mode, when shortcut is moved, it will automatically move back to lock position in seconds.
To change lock position, just move it to new position & hold in seconds)
- Long-press floating shortcut to reveal more shortcuts (memory boost/app shortcuts/system settings)

★ Notice:
- If you need to uninstall our application, please must uninstall it from “Screen Lock Settings”.

It deserves 5 star!!! Fixing the fingerprint problem on my Huawei mate 9! I was looking for the screen lock app for months! Thank you! Update: Have to use PIN to unlock after APP lock. I guess that is due to the system security reason.

Would have given 5 star but screen locks 5 sec even if setting is changed to immediate. But still worth it for emui 5 devices. No other screen lock works without bypass device manager pin on emui

5* for great work and up to date. I'd change the setting to 'immediately' but my devices will lock in about 6 seconds.then the fingerprint will be functioning. hope you can fix this issue.thank you. P9 Plus(VIE-L29)/Nougat

This app still not fully support the fingerprint. If I use the experimental, it only dim my screen not lock it. If I use the one that not experimental, it needs put pin again after fingerprint. I will give 5 stars if it fixed.

This is a great app offering a lock icon instead of wearing down your lock button. It also provides quick and easy personalization settings.

Perfectto, now I can save my power buttons. Work on my sgs7 with experimental fingerprint option enabled. All I have todo is touch the lock shortcut and wait for 2 secs. Then it will lock completely! Thanks dude..

Best app for fingerprint included mobiles. Other most apps are not respondind to fingerprint unlock

EDIT: works! :D Fingerprint unlock doesn't work. Alcatel Shine phone. "Fix fingerprint unlock not work" doesn't help. Once I touch fingerprint sensor, I am still asked for password or pattern. But if I put phone to sleep with the hardware power button, all I have to do is to touch fingerprint sensor alone. I tested about 20 apps today no one works that way (namely like hardware power button press).

Overall works great. Flexible to setup and in usage. I use the floating icon that can be scaled to my needs and the opacity setting is also great - I use this along with "Floating Shortcuts PRO" (by GeeksEmpire) and a daydream launcher, which together provide a complete and quick to access, persistent onscreen UI. The only problem I have sometimes is that the icon does not want to be placed on the right side of my tablet's screen - it "feels" the right side limit in the middle of the screen. But I noticed that when opening up the setup screen (and then the icon goes back to the middle), sometimes the icons will let itself be placed where I want. I've turned on the option to "auto return to lock position" which helps a lot. Sometimes the icon disappears and it takes a bit for it to get back, and sometimes it returns to the center of the screen.

Does it really take about 3 seconds to lock the device after the screen shuts off? I just noticed now that whenever I press the capacitive keys (I have a Samsung device) within the 3-second time, the screen would still activate. I'm not sure if this is just on my phone if this is really the case for everyone else. Immediate lock would definitely be preferable. Thanks. (Updated)
