All procedure was followed as usual before installing the fix version. I uninstalled the previous version, restarded the phone, enabled Google play store back on, Google play protect was disabled, notifications as well, like the old times. 4.0.5 worked perfectly for about six days. Suddenly, yesterday morning at around 9-10, it stopped. It said the target phone wasn't connected, while I could see in Messenger and Viber that it was connected. When I had a quick look at the phone, I went to settings-- security, taped the play protect and there was a message saying that there is a malicious application trying to steal information from the phone and all that, and prompted to uninstall it. I checked all the app in the phone and it was still there but I play protect must have frozen it. There wasn't any message shown on screen so that the target could see it thank God.
