Weird lockscreen issue
I've had my Xperia SP for more than a month and I've had any problems with it up until yesterday(December 31st). I was coming home from the gym and I turned on my phone and notice something weird on the lockscreen - see attacthed image.
I have no idea where that came from or whats causing it. I tried rebooting my phone and disabling/re-enable the lock screen, but it still won't go away. Has anyone had an issue like this before? It's really weird.
