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.

I'd like to suggest a feature. When taking the picture of an intruder after he tried unlocking the device. There should be a trigger for camera flash and shutter sound. This strange action might as well scare away the thief from going away with the phone.
