- A139, M1S
My pre-release A139 has normally been very reliable. However I checked the files from a drive yesterday and saw there were some missing files.
- The A139 correctly recorded 1-minute files on all 3 channels up to 2022_0920_125643_F
- The next file 2022_0920_125743_F is only 3 seconds long, with matching I and R files.
- Then there is a gap of 6 seconds
- The next file 2022_0920_125753_F is only 2 seconds long, with only a matching Rear file. The Interior file is missing.
- The A139 did not record the final 10 minutes of my journey.
- It did switch correctly to parking mode when I stopped at 13:08, and recorded all the time while parked.
- It did switch back to normal mode again at 13:31 and appears to have recorded OK everything after that.
- I have startup sounds enabled, and the camera did not make any shutdown or startup sound while driving.
- The A139 is hard-wired to a LiFePO4 battery with HK3
- The microSD card is a 256GB WD Purple U3
- The missing files are not in the RO folder.
- All GPS time stamps appear to be correct.
- FW is version V1.6-0602

I suspect it may be a memory card issue. I will run some checks on it.
It is a pre-release A139 received for testing, so it owes me nothing. I do want a reliable camera though, so it might be time to buy something new.
