i have been using my xperia z2 for 6 months now.i sent a message to someone yesterday and the next minute my phone didnt respond to touch at all.it's been about 24 hours now.every other thing is working:i charged it,restarted it by removing the sim card ,can see all my notifications,the time is changing ....but i can't use it because the home screen is locked.all other buttons(camera and power button) on the side are working perfectly. any help,anyone?
