DJI still didn’t totally fix "Take Knowledge Quiz" problem, and some people still experience the trouble. I found there are two more bugs that need to pay attention.
1. Yesterday I helped my friend to update the 0400 firmware, I failed for more than 10 time after it installed 98%, then stuck over there. Finally I noticed that the firmware installation needs at least 2Gb free space, so I deleted over 800M cache video and images, deleted all fly–log. I finally updated the firmware within 10min. As I know that the only way to avoid this situation is saving the cache file to external microSD card. I put a 128Gb microSD, however, when I set up “save cache to SD card” from control interface, it just automatically save once, then all go to the SC again, I need to manual clear then or manual transfering. 2. Many people experienced even worse situation as I saw from other forums: when they turn on the power of Smart Controller, it frozen on the first DJI log page. There is no way to go though “Setting” to clean the cache file and release the internal space. Please tell me how to deal with this issue.
DJI should add a warning information on new firmware update: The memory of Your Smart Controller is almost full, please delete some cache video or cache file to release more space.
It is not a problem for me, because I usually clean the cache file after two or three flights.
