My X150 Camera Has Frozen And I'm Unable To Switch It Off. Reset the camera by holding 'Shoot' button for 15 secs. Please make sure you use a class 6 SD card with the camera. You may have this problem if you use a SD card of class 10 or above. Class 10 SD cards require minimum 10Mbps data transfer rate. Have more questions?
