I decided to give Tetra Lockscreen a try again after the latest update. It seemed to be working great but when I started my camera (via the hardware key) the screen went black and remained black (except for the status info: clock, signal, etc.) until I did a soft reset. Same thing happened when I tried again but after uninstalling Tetra the problem went away. Has anyone else experienced this? I am using an Icon on DP so I'm curious if it's a firmware issue.
