Ratings and reviews

Not bad, ran into a little problem when I had the scope plugged in first and the app not picking it up. All I did was unplug it, then plug it back into the phone with the app already open. Connected right up and was good to go! There may be a manual that originally came with it that probably tells you that, we bought it at a garage sale for like $20. But it's not needed, just download the app and plug it in, and your good to go. Minimal knowledge or experience to use.

No Longer Works! I am using a fully updated Samsung Galaxy S23+. The app has been updated, un-installed, re-installed, and all permissions have been given. This app and borescope worked about a year ago when I used it last, but not anymore. When I try to click the record button, an error message appears saying "No ET16 Connected". When I try to modify the USB connection settings, the control will not switch control modes. Still waiting for support to get back to me.

Doesn't actually do anything. Says it connects; doesn't display. Managed to get it to display with "USB Camera App" generic app, but focal range is too small. Can't make out anything within an inch of the lens, which is mostly what I need it for...you know, small cam for small places... Also can't make out anything over a foot away, so if you get through a small space into a larger one, good luck figuring out where you need to go from there.

What’s new

After the user declines camera access, the app shows a prompt that it is required and will lock the user out of the app.
If the user closes or reopens the app, it prompts the user again to accept access, if it is declined, the same warning is shown.
The user then will need to go to settings > apps > ET16 and allow camera access
