Screen Lock Customer Insights

1. I switched to a touch lock that just uses a silent notification to activate.LOVE this app!!! Actually had to install it on ALL my devices now, because once you use it, you can never go back! I literally can not work at all on phones without it anymore! And it's not just for screen lock either, I can't live without their screenshot function! It makes it sooo much easier to use! My only wish is that they can soon add a way to be able to block touch on just 1 side/app, when using a split screen function... (Please, Simi??? 😘)Works exactly like I had hoped.

2. A single ad when you first launch it that never interferes with actual use seems like a completely fair trade off for the app being free.My power button is broken, and sure the screen will naturally turn itself off after a few seconds, but having the option to shut it off on the fly was just what I needed and just what this app offers.

3. My button fell off of my phone and I accidentally flushed it down the toilet (yeah ik 🤦🤦) and I couldn't get a replacement so I looked for an app that would give me a on screen button similar to iphone and this does just that and you can customize the button to look like whatever you want lol, I'm honestly so glad I found this app, it's an actual life saver.

4. I like the ability to swipe down to close my screen and this app linked to a launcher gesture is perfect.The app is great but the accessibility feature keeps malfunctioning.. That makes the accessibility setting faulty and I frequently have to turn it off and turn it back on.

5. I can't quite figure out how to use certain aspects of it, but just slapping a custom button on the screen works fine so there is no need to go deeper.This app is honestly amazing.

6. Using on S22 Ultra after Oneui5 update when the launcher gesture for closing screen stopped working.

7. My phone screen buggs out from time to time and spam clicks the screen even if nothing is touching it, this can be annoying because I listen to music a lot and it will skip the songs.

8. I am only using it to power the phone down instead of using the power button which is hard to push when you have a phone cover.

9. I needed a home screen icon to lock my phone.

10. Been using for a while now and I gotta say, while it was confusing and weird at first its super customizable and usefull.

11. Not sure if it's a coincidence or not, but now the app requires accessibility and other permissions I didn't want to grant, and even when I did, it still didn't work.
