I've been searching for an app that I can do wired tethered shooting on an Android phone or tablet with my Canon camera.
I was told (even by Canon support) that Canon didn't work with anything but EOS Utility running on either Windows or Apple.
Well, I found an app called Camera Connect and Control that works on both my Android phone and Android tablet, and works with my Canon T8i (850D).
It's a free 3-day trial, and costs $9.99 to purchase. The developer says, “The purchase is linked to your Google account. If you use the same account on your other device you can use all purchases.”
It supports both a Wifi connection, as well as a USB connection. I didn't try the Wifi, since I already have Canon's Camera Connect.
Photos are stored on your camera's memory card, that you can then download. It will do both still photos and video.
I got the app from Google’s Play Store.
