Biometric Solution (Free)
This is a security application that locks your other apps with a pattern or PIN. The developers also claim to have a fingerprint option, but it doesn’t seem so. It has a poorly designed interface cluttered with ads.
The fingerprint lock doesn’t work even if your phone has a scanner. You can see the icon, but nothing happens when you press it. The PIN and pattern options do function, but not well. Sometimes when you open an app, it doesn’t prompt for a password. You’d have to restart the app to use it.
Poorly designed programme
Corrupts apps in the background
This piece of software has a habit of shutting down background apps. There are so many ads on the UI. Only one tab contains the single feature that you need. The rest are links and promos.
Drains your device’s memory
Since it runs in the background, resource consumption is a problem. You need to give special usage access to other apps on your phone. That means a lot of memory goes down the drain. You may also experience a significant increase in loading time the more you use it.
Causes other apps to crash
The only reason to use this app would be if you’re sharing your device with someone else. That is not a good idea, to begin with, and neither is downloading this lag generator. Save yourself the hassle and stick with the standard protection your Android already has.
