This app used to work perfectly on my phone. After the August 2022 update it is not working properly. After 8-10 attempts I might get one picture of an intruder (set for 2 failed attempts) and sometimes no pictures at all. Defeats the whole purpose of the app. I have noticed that many negative reviews are after the update date. I wish I never updated or had kept an apk file for the older version. Some apk files won't install or work but it's not working now anyways. I have to uninstall.

Its quick capturing of incorrects patterns and passwords is unarguably fast and accurate. I have no fear whenever I'm charging my phone in a public place with the loud alarm when unsuspecting individuals tries to unplug the charger. I urge that you continuously maintain that level of security on users of your app to keep the minds and trusts of the app intact and make us feel our phones are safe at the mercy of your app.

Your app is very useful and important for me 😊😊 Please Add a new feature in the app that allows a user to lock their phone remotely by sending a message from another device, even if the phone is currently unlocked. Also include a feature like a fake airplane mode and a fake power-off screen so that a thief thinks the phone has been switched off and becomes less cautious, while the user can continue tracking the device in the background.ā€
