I have a similar problem my Osmo action takes a long time to initialise the card on stratup. Then if I start recording it will not stop recoding or access the menus unless I switch the unit off or remove battery and restart the device. Sometimes it just freezes and you cannot access any functions or turn it off. Then I need to remove the battery to restart the device. I am using a Sandisk extreme pro U3 170MB/s card 256GB and a Scandisk Extreme U3 16GB card both have the same problem. The unit can also not format the memory cards return a message format failed. The firmware is 01.10.00.40(7251) which seems to be latest from DJI download site. Also cannot reset factory settings it just starts and never finishes reset process before it runs out of battery. I have hardly used this device since purchasing it it is such an annoying situation so as previously put I have an expensive paper weight.

I have tried the downgrade unfortunately no change I suspect the unit is defective but I doubt it will be cost effective for me to return it and have it fixed as I reside in South Africa.  Maybe I should have purchased the gopro would have been better supported here.

sorry to hear that, DJI should be accepting the return to their nearest facality. if hte camera is out of warranty then it is best go get another camera and Auction off

Really sorry to hear that you have problem with your OA.

Open a ticket with DJI about the problem and ask if they have a solution that would not cost you anything or not much to get a replacement.

About gopro or other brands, they have all their issues, especially gopro. But I can recommend buying gopro 9 or 10.

And people genereally complain about gopro support in rest of world it seems like, but idk about that.

So you more or less  did not buy from DJI and DJI is not  taking the warranty?
