"There are trespassing signs. Check it in Observer Settings screen." This is the above message that I am getting whenever I open a new app on my Android 4.1.2 Samsung Galaxy Grand DUOS. This has started suddenly when my child was just playing a simple ABC kind of rhymes.
Following things have been tried by me, in the given order, but without success: [a] Check out which was the last 3-apps installed and the uninstalled them [b] Cleared App-cache [c] Did a restart
Any pointers or solution is welcome. Thanks in advance for your help.
