I have the same problem Mr Diddy. And your solution is that I uninstall, one by one, every app I have installed - all through Play Store and all bearing the imprint of Google itself - to find out which of them has picked up adware? This means I have to leave my tablet on and wait for one of the remaining apps to wake me in the middle of the night, so I will then know that it wasn't the app I uninstalled that was causing the trouble. I then reinstall the one I uninstalled, uninstall another and wait to see if my sleep is disturbed again. This could take weeks, possibly months, of insomnia. And you are seriously putting this forward as a solution to a high-tech problem in the year 2018. Have you slipped through a time warp from 1918?
If this is what your product does then it is simply junk.
