Problem
You suspect you have a bad microSD port; your Wyze Cam v3 doesn't detect the microSD card, or doesn't back up correctly.
Troubleshooting
If you think your Wyze Cam v3's microSD port is bad, check the contents of the microSD card on a computer to make sure that the card itself isn’t corrupted. If it is, try reformatting the microSD card and testing it in your camera again. Related article: How to Format your microSD card.
