My hardware version is S720C.01 and the firmware version is 2.3.6. SD total space is 1.85 GB, available space is 1.69 GB. System storage available space is 742 MB. My problem is if I get near 100 photos, the photo gallery locks up and I have to remove battery and reinstall to get gallery back. I have deleted photos to 80. So, will a larger SD card fix this?
