I have noticed lately the A229 some times ( rare at most like 1 time a week ) will not start recording, but if i pull the power and then insert it again, it will record.
I am not sure if its due to some of the new cards i have been testing are marginal in compatibility, but TBH i dont think so as its so rare.
But ! after i have filled up the 256 GB Trancend card thats in the camera right now, i will throw in one of the cards above i have tested and which did not have this strange occasional failure to record issue.
But the issue was there with the previous card too ( SP ) and now the Trancend ultra performance.
