So, out of nowhere, my Lumia 1520's Search button (Which activates Cortana) is being ghost pressed and Cortana pops up. This happens every 2-5 seconds when I'm holding the phone. I've noticed that if I hold it in certain ways it doesn't happen. This is a new issue as I've had this phone for about 7 months now. It is an RM-937. Is there a way where I can completely disable the search capacitive touch so that this stops happening? I've tried resetting the phone, I've tried Lumia Recovery Tool, I've tried everything. Has this happened to everyone? This phone has become unuseable because of this, so I'm using my back up BLU Win HD until I can get this fixed.
