USB Camera Viewer

Great for a free app. Pleasantly surprised. Occasional refresh glitches. Ads do pop up when changing settings as others have mentioned. Settings default back to a lower resolution upon exit and restarted or reconnected. The biggest caveat for me is having to disconnect in order to review the video recorded on the camera. Won't play on connected phone, and camera display is always blacked out while connected. But, what do you want for nothing? None of it is a deal breaker for a free app.

It actually works. After trying a half dozen of that looked like the same app with different names this one started up without featuring a set of ads. It went straight to the screen where it should be and it worked, The others were Chinese knock off apps that had lines all over the screen, This one was clear as can be. Using the more detailed setting of 1280x720 uses the majority of the screen. The 640x480 uses about half the screen. Only problem is it pops us an ad when the setting is changed.

Downloaded it, plugged in the endoscope and it worked. Not really a high bar but it is in stark contrast with the last two apps that I downloaded that didn't work. Also like the fact that it doesn't share info with third parties; the other ones I looked at do ☹️.
