Micro SD cards not recognized



I have three of the Wyze Cam2 model, and so far I love them! Only one major issue, which involves micro SD cards.

I bought three 32 GB Kingston micro SD SDCS cards-at separate times-and all three appear to have failed after approximately one month of use.

To further troubleshoot the issue, I used an Adata 64 GB micro SD card in one of the cameras…it worked well but also stopped recording when it became full. Multiple attempts to format the card using the Wyze app failed. On the fourth reformat attempt, it worked. Strange, and worrisome!

The issue appears to be when the SD card becomes full. The camera stops recording and the micro SD card fails to reformat, using the Wyze app. After that, the micro SD card appears to completely fail (at least with the Kingston 32 GB micro SD cards).

I assumed it was the cards failing, but it seems strange that 3 cards, plus one from a different manufacturer, have not worked consistently, and have suffered similar issues.

Here’s what I’ve tried:

  1. Power-cycling the cameras and removing/re-adding the devices in the Wyze app

  2. Reformatting the micro SD cards with the Wyze app

  3. Moving the micro SD cards to different Wyze cameras

  4. Reformatting the micro SD cards using a Windows 7 laptop, Windows 10 desktop (cards not recognized, no way to reformat them in Windows)

  5. Reformatting the micro SD cards using a digital camera (error message: SD card is locked)

As for method 4, neither Windows 7 nor 10 will even recognize the micro SD cards…I tested both computers with a micro SD card that had never been used in a Wyze camera, and it was recognized instantly and easily.

Method 5 didn’t work; the camera says the micro SD card is locked. I made sure the lockable switch on the card was in the unlocked position. Still no luck.

Anyone else suffering from this issue?




Same issue. Did your first two steps.


I have the same issue. When the SD card is full, it stops recording rather than overwriting from the beginning. I have my cameras set up to only record motion.


I read in another post that reformatting the card with a GoPro works. I tried it with my Hero 4 Silver and just like that, issue resolved. It has not filled up yet so I don’t know much about the above overwriting issue, but this got the card to finally work in the cam. Hopefully this will be fixed in future firmware updates.


I had this happen once and reformatting the card from within the app fixed it.


Same problem here, tried all of your five ideas, no joy. Wyze Cam Pan was reading the card, but no longer recording, so I did a reformat in the camera app. Now the card isn’t being seen at all.


Here is what worked for me to get my SD card recognized in the camera. I watched a Wyze cam tech video and they advised that we should use a computer to reformat the SD card before installing it in the Wyze cam. I reformatted my new SanDisk 32gb card in my laptop ensuring it was Fat32. I then installed it in my brand new Wyze cam and it was not recognized, I tried numerous steps as others have posted but still could not get it working. I noted that the SD card could not be reformatted in the camera as the format button was greyed out.
Thus, I reformatted the card in my laptop not in FAT 32 but rather in exFAT, I did this in hope that when I put the card in the Wyze camera the format button would not be greyed out…I put the SD back in the camera and indeed the format button functioned. After reformatting the card it immediatley was recognized and started to record events. I hope this works for others.


I am collecting some info on similar issues. If you still have this issue not solved, can you check something for me? When you format the card in camera, check the “SD card memory available” before and after formatting. Before formatting, do you have a low number (eg. 1.x GB) available out of 29.x GB? The camera may report “formatting complete” but afterwards, it still says 1.x GB available. If the formatting was really successful, it should show 29.x/29.x available (IOW, the card is empty).

If you are seeing the same low available space number after formatting, then I believe your card is damaged and will not be able to be formatted even on a computer. If you want, you can remove the card and try to format it using the tool here:

SD Assoiciation

SD Memory Card Formatter 5.0 for SD/SDHC/SDXC

The SD Memory Card Formatter formats SD Memory Card, SDHCMemory Card and SDXC Memory Card (respectively SD/SDHC/SDXC Cards) complying with the SD File System Specification created by the SD Association (SDA).

I think you will find it report errors and fail to format. In this state, you can copy off what’s still on the card, but cannot format the card or write new data to it.

Let me know if this is what you’re seeing. This is what I’m trying to track down.


Hello, and sorry to all for the radio silence!

I finally realized after some testing that 3 of 4 of the Kingston microSD cards were bricked. I thought it was the cameras that were the issue, but it turns out the microSD cards never worked, brand-new out of the box!

The 4th Kingston microSD card I bought worked for a few days, and then failed.

After this experience, I will never buy any Kingston products again.

I purchased microSD cards from a different manufacturer for my Wyze cams and they have worked for months with no issues.

Good luck to everyone having trouble, wish I could have helped more!
