Been using USB Endoscope Camera for a couple months now. It’s basically an app that lets you use an external camera, like a borescope or microscope, with your Android phone. Pretty solid app if you’re into that kind of thing.
Here’s what you do: you just plug in the camera via the USB port and the app lets you view the live video feed, take photos, and even record videos. There’s also a bunch of settings to adjust the image quality and other stuff. And it worked pretty well with the different cameras I tried – took me a while to figure out the controls but it’s not too complicated.
Look, if you’re into inspecting small spaces, checking out damaged stuff, or just playing around with microscopes, you’ll probably like this. It’s not perfect – the video quality can be a bit iffy sometimes and the app crashes on me every now and then – but overall it does the job. Worth checking out if you need an inspection camera on the go.
