I don't understand the poor reviews. I followed the instructions and it works great. Used it to check out the ducts in the house, to find things in my crawl space I can't get to, used it to look around in a lot of places I can't get to. And worked like a charm on a couple of different androids and android OS versions. Easy to use. Press n hold the on button, connect to it via wifi, THEN run this app. Can't get any simpler

Everything is in Chinese.... what's the point if there is no US-language-friendly version? It used to be fine (and in English) b/c I've used the app for years... then suddenly it updates and is no longer practical. I'm not just pressing buttons b/c who knows what I'm agreeing to or allowing to happen on my phone. Seems more like a scam now and it doesn't let you skip the update or revert back to the working version. >:(

This worked like a charm for me. Set the switch on the side to wifi, plugged it into my Samsung S9+, connected the phone wifi to the listing for the endoscope and was up instantly. Went into the app to change resolution to 1080P and stuck it down a drain to test it. The light switch on the endoscope brightened it up at least 2x over the OEM setting, and I could see individual rust spots and hairs. Then, just for kicks, I changed the adapter on the end of the endoscope to USB A instead of USB C which fits my phone and plugged it in to a portable USB charger I use on trips. I left the switch on the endoscope on wifi, NOT switching to USB, and opened the app. Worked perfectly. The only thing I haven't done is go through each resolution setting in the app itself. All I can think of is people getting confused as far as the negative reviews. You HAVE to set your phone or tablet wifi to the listing that shows up for this unit when it's plugged in. Otherwise you'll just get an error. If you plug into a battery pack as I did, the same thing applies, you just don't use as much phone battery that way and it's a lot easier to maneuver without dropping your phone or dragging it around. Also, once you see the picture right side up, I'd put a mark on the top of the camera - it helps with initial alignment!
