So I've taken apart my z5 premium, made the rear glass clear, after turning my phone off I decided (out of curiosity) to unplug the rear camera module to look at it, plugged it back together and turned it on and it gets stuck on the Android screen, plugged it into pc companion to rebuild the software and it still didn't work, so I unplugged the camera module again and for some reason the phone boots OK without it on...... It's not the end of the world I'm due and upgrade but of definitely like to keep this as as spare (preferably with a working camera, any ideas why it won't boot with it plugged in?
