Hi DJI FPV drone users. Today I noticed that the OSD data stops refreshing from the moment that the SD card runs full. Everything just freezes at the last value before the card was full. I only noticed it because I was trying to fly very close to the ground and was surprised the height data did not go red as usual. What scares me most is that the battery percentage was not refreshing either. I would call it a BUG ...

"I would call it a BUG"

YES! A big one.
Thanks for the info.
