Random Apps open

Oct 30, 2013

I'm using the Mi3 with 64 GB WCDMA with the up-to-date Multilanguage Rom.
It happens quite frequently that when ever I unlock the phone some random apps showing up running.
I.e the Stopwatch , musikplayer etc etc . It seems that the screen reacts to touch even so the screen is locked.
And of course if I touch the screen when locked on purpose nothing happens.

So, anybody with an idea whats going on here ?
