No, there is a magnet in her pocket. It triggered the plip flap smart cover feature.yesterday i gave my phone my wife. she put it in her pocket - i did'nt know, how to place it on my bike. when she gave it back to me, i had the same screen and i reset it by removing the battery. i guess that in her pocket the home button was constantly pressed.
Thanks to haggertk for his perfect 18.1 version. i'll spend some money to our local food bank as haggertk supposed to do.
