Excellent app 👍 I got this just for the lock animation, not even to save the hardware, and the Arrow Box animation is SUPER COOL! However, using the power button still locks the phone normally. It would be nice if the animation could be added to this as well, but I'm not sure if this is possible without rooting. Still there are plenty of other ways to activate it. The animations are very smooth, with plenty of set-up help, tunable adjustments and features, this application is very well made.

Works flawlessly on my Galaxy S10+, even with Smart Lock. I tried several other apps, but this one is the best. Not only does it work without any issues, it has a great-looking UI, too. (Some of the other apps looked like they were just slapped together.) I happily paid the $1.99 to get rid of the ads and to support the developer. Great job! --Ron

Very non intrusive app, I think I saw only 1-2 adds when first setting it up. There were some functionality problems at the beginning but some pop-ups (or something similar gave detailed explanations about solving the issue that was automatically detected). Extraordonary well done, useful and friendly app. I'm using it at every occasion when I lock the phone protecting the fingerprint sensor (is stupid to have to push a button to close the phone when none needed to unlock it).

Amazing! After 2 years of trying several soft lock apps for phone with fingerprint sensor, I thought there's no workable one. The one that I was using (most about the same), will have to wait 10 seconds for it to totally lock the screen, a touch on the screen within 10 seconds will pops out the navigation button and fingerprint sensor can't wake the screen... This app really enhance my experience of using a phone with fingerprint sensor! Thank you very much for this app!🙏

The app is lite. It works well with fingerprint sensor. However, some fucntions should be improved: - it takes too long to fully turn off screen (3-10 secs as advertised). During this process, I CAN'T do anything, even press power button. It should be about 1-3secs. - I think it hasn't been supported for 19:9 ratio screen so far, at least on my Nokia 6.1 plus. Hopefully it will be improved in next updates.

Met my immediate goal of changing my lock/unlock sounds on a device that can't be rooted yet. This app is fantastic. If you really like unique customization, or have a damaged lock button it's a must have. There's a ton of cool features, like flip lock if you use a folio or dual screen case (like me). I ended up getting the pro version, I liled it so much. Great app!

This is a great app. Turning the screen off when charging or closing the cover is great. Smart lock integration is very nice... So I'm modifying my review after a few more weeks of testing. Turns out my proximity sensor in my S7 Edge is just very sensitive. The app is working fine, it's just my phone. I've saved so much battery time because of this app. Serious thumbs up.

This is the first flip cover lock I've found which will unlock with fingerprint. At first the app was disabling frequently and I had to go back into settings to re-enable it (see below). The app config is comprehensive, but a little confusing. UPDATE: Thanks to author for prompt support. The reason the app was disabling is that the system kills idle apps for battery saving. This is overcome by changing a system Setting. The app now works perfectly.

Just downloaded this app for a faulty power button on Samsung Galaxy J3. Took about 30 seconds to complete. So far it seems brilliant almost too good to be true, works perfectly. I'm a bit confused and concerned about the other 2 buttons which were downloaded with it, one was a screen off button which I guess is self explanatory but the other an admin button I'm not sure about. Maybe someone could enlighten me as I don't want to play with it in case it locks me out completely.

Very convenient and helps to prolong the life of your lock screen button. Has an option where you can drag your screen down and lock it from there so that you can lock your screen while using any app. You can also create a shortcut on your home screen and simply click on it to lock your screen immediately. Been using this app for more than 5 years on 3 different phones and honestly have never had a problem with it. Can't imagine not using it

A. S. Dec 14, 2019     

Not a bad app. Took me a while to get used to where it can be a little confusing. I still am not positive what difference is between two lock systems. Like that I don't have to use power button, but Reason I'll probably uninstall is that is is cutting my battery life down it's new phone and went from lasting 2 days to one. Without using. No I have not installed anything else since. Wish i could find an app with tap to unlock and wave.

It's so cool! I just can't stop turning off my screen now! Very nice, handy and stable! Since I have a flexible back shell that has a slightly thick opening for the power button, the button is a bit difficult to press. So a button widget icon on each screen (or you can even use the shortcut icon placed in the bottom with the fixed icons) plus several other features, makes for a perfectly thought-out app! Congrats on this!

It's a go to app for them who want complete security of their device. Some key points are.. 1. Easy UI..even a novice can use it freely within minutes, they just have to know English! 2. Unpaid features are more than enough to secure your device..but if you want a completely beautiful experience...just go for the paid version 3. Many functions and more than enough tweaks I would recommend it for everyone !

Shu. S. Mar 22, 2022     

This App is the best with all its Pros it is amazing.👍🏻 Only 1 con & its that i cannot get screen lock sound as i click my button. the sound appears after my phone is locked, too much delay it works perfectly for screen unlock sound with no delay. if you can add 1 more option like screen lock & animation start, then it will play lock sound for both whenever you press lock button & for perform animation

Tif. L. Nov 9, 2019     

Keeps messing up lately.... It's been a very useful app but late lately I have to keep resetting my personal setting. I have the sound turned on for when I lock and unlock my screen and it's been working great up until about a month ago. Now I have to keep going into the app the reset it.

Bre. R. Nov 21, 2019     

Grateful this exists! Super reliable and easy to use. Button is right there to lock screen whenever you need to. Especially since my phone's side button fell off. It saves me time because now I dont have to wait for the screen to automatically switch off, and I love seeing the locking animation!

Mat. W. Mar 20, 2022     

My only problem with the app is there is no "keep screen alive" feature for the smartlock. Since most Android devices no longer have the ability to disable the sleep timer, this renders the feature useless. Because after the set sleeper time, the phone fully locks anyways.

Min. T. Aug 28, 2019     

Great! The only app that does the locking right on my phone :) There's only one sad bug: it doesn't lock properly when the app that has enabled "keep screen on" is in foreground, instead it only turns screen black and i need to press power twice to unlock. That is using smart lock. A fix would be very appreciated <3

Rob. Nov 13, 2019     

Works A1; only issue is the fact it doesn't turn off external apps 100% of the time, so things like Audible & Youtube play until your phone's genuine screen lock kicks in after 30sec+. Also kinda pointless (for my devide model at least,) to modify the appearance of the Lock Button. Spent 20mins making my button cute, but it's still 50 Shades of Gray nonetheless.

Viv. A. Jul 4, 2020     

Sometimes the floating button gets disappeared. Another improvement could be on response time to lock the screen. I liked the options to customise the look and size of button. Also option of floating button is good. Overall I liked the app but may need some minor improvements.

Soc. Feb 8, 2019     

Very easy and fun to use. It's fun to change the lock screen sound. Works good. However this app doesn't really stay on at times. I'm not sure if I'm just not doing something right or the app just shutdowns at random. Otherwise just what you would expect! Good app

Jef. A. Feb 11, 2022     

I almost couldnt get rid of this app I clicked uninstall on play store nothing happened I tried from apps menu to uninstall Nothing happened I clicked the icon all it did was put my screen in low power mode making it look locked . Nothing would get rid of this app i even restarted nope still there. I checked the notification area and viola Got rid of it. Very frusterating app Wouldnt reccomend anyone to install this!!!!!

Mic. B. Nov 13, 2019     

I have a broken power button that works on and off so with this and my finger scanner i dont have to worry about not being able to get into my cell, sadly though not thst it is super important but all the other features dont work so well.. the hovering back and fourth motions to turn off or wake the phone only work about 1/3rd the time as well with the pivot option to where when you put it in your pocket upsidedown the power turns off.. like i said though not NEEDED functions

Rup. M. Aug 24, 2019     

Works great on turning the phone off, but wont turn the phone on, which is more important because you can wait for your phone to turn off on itself but you cant wait for it to turn on, some features are not free and can only be accessed on the Pro version, by the way I was using the shake feature

Ron. W. Jun 28, 2020     

FINALLY one that does it RIGHT...I have a Note 8 with biometrics, and downloaded about 15 screen of apps before finding this one. It not only blacks out fast, it allows fingerprint unlock AND doesn't lock straight away (the screen lock time out in phone settings is kept). AND there are plenty of little options and adjustments for individualty...BRILLIANT 💥💥💥

Nad. S. Jan 31, 2020     

Have power button issues on Oneplus. Very good app and quite functional. Easy and instant phone display off and phone lock. But issue is the phone is not waking up most times when the system lock kicks in. Takes time. Shaking or fingerprint or sensor waking up doesn't work. Have to keep pressing the power button to wake up device.

Ric. P. Nov 21, 2019     

Nice app that does what it's supposed to - unlike the first one I tried. My only issue is that some of the user settings could be a little more straightforward, and 5 or 6 of the 'animation' options just don't work. All in all, very useful.

Joe. M. Jul 15, 2020     

Using on Samsung A20s, took a little time figuring out, i put the icons on home screen for ease of use and it works perfectly, activates the screen when you flip the phones cover, theres loads of other config options though, no ads. You might have to fiddle with your phones own internal locking config, its the best screen lock i have tried and the only one fit for putpose, well done dev A++.

Mil. C. Oct 15, 2018     

It worked awesomely in shake screen to lovk mode and was a great app...until latest update. Now shake screen lock does not work at all. Uninstalling/reinstalling did no good. Not working regardless if settings. A good example of updating destroying a perfectly good app. Cannot recommend.

Par. M. Nov 10, 2018     

Great app, solves my issue of Lock phone without use of Lock button. Because Pixel 3 don't have double tap to sleep feature. After locking phone with the help of this app you can easily unlock phone with Fingerprint scanner.(Smart Lock) but there is one thing is missing, after this Double tap to wake for glance screen don't work. That's the reason I gave this app 4 Star.
