Since the battery of my GT31 was drained the user interface of my GT31 is damn slow. Meaning: Key lock or unlock message will be displayed for more 30 sec. and it beeps as long. Same for new file (more than 60 sec.) message, etc. Logging still works - it is only the UI that sucks.
I have updated the firmware but without any success. I have my GT31 for a while now so I guess it is not the SD. It definitively started after the battery drained.
Btw.: any news on a successor of the GT31 on the way? Or a better alternative?
