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.

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.”
