card has been formatted befor plug in, tried different cards
the cam says “micro SD not avaialbe”: however, when i unplug the card and mount it to my computer, i can see it has created a folder for today (i.e. the date when i first plug in the card) which means actually the cam is accessing the card
tried different firmware: 4.9.4.169, the latest one 4.9.5.36 (and one another version in between, i forgot the code), problem persist
I had the same problem. I had to format in laptop to get the sd to work. After that the camera is able to format it. You can slip in to a phone and format it.
You didn’t give any details about the card size or format? Having said that, the only problem I’ve had with any card was a 128GB formatted with Fat32. Once I just did the standard Exfat in a Win 7 PC, it worked fine. Same goes for a 64GB done in Exfat. The rest of the 32GB (SanDisk) I just popped in the cams without ever looking to see how they were formatted, and they too worked fine.
Although many people use them Wyze only currently supports 32gb cards. The camera will only do a quick format on a card, which will not overwrite bad sectors, etc. The best bet is to format the card in a PC using af full or deep format. The industry standard program for this is Provided Here.
If that doesn’t work you could try a factory reset followed by reflashing your firmware.
Last but not least if you are still under warranty you can Open a Support Ticket and request a replacement.
