Reboot! Then try the device. Clear cache before reboot if you want to be sure.

I found my HTC One M7 became laggy at some point around the 2 month mark. I had stopped with the million apps then, and I always had about 400-500 MB RAM still free when most active and processor was maxed out (but not like all cores were fired up the whole time.)

Mine does the long pause when I try to turn the screen on too sometimes, even though I have a task manager kill everything when I lock it/screen off.

i tried to deactivate the app from device administrator but this time it worked fine , and i uninstalled the "Prey" app and the phone works fine now .
