Review on Oxbird50X-2000X HD USB Microscope for Adults - Digital Microscope for Android Phones (non-iOS iPhone), Mac & Windows 7/8/10 Compatible by Franz Esquivel

I had to try 4 Android devices to find one that worked. Doesn't work with Pixel 4A (probably phone issue), doesn't work with FireHD10, doesn't work with Moto G6. It finally worked with the Moto G7. It also managed to get it to work on Windows 10. However, the "Snap" button does not work on any of these devices. Because of this, you must hold the microscope steady (unless you can use the stand) and try to take a picture with the software. The maximum image resolution is 640x480.
