Krita. I got a low end table and it works fine for my needs. Just be aware that you can't intall plugging on android yet, and while you can animate, you can't render the animation.
You can make kirta work on a phone by increasing the dp inside the developer options in your phone.
I downloaded it years ago from apkmirror and update it via the app itself. It has never made those connections before until last week. I think that maybe the connection it made to Google fonts was because days ago (maybe a month ago) I changed the language and it needs to connect to the Internet to do so. But I can't find a reason to why it connected to telegram, which I don't use.
I've been using Mixplorer for years because is simply the best file manager on android, but I try just using open source.
But the reasons I'm finally moving is that it doesn't update regularly and a couple days ago I find it making connections to google and telegram.
Yes, I use App Manager. On APKs chose open as, app manager, scan. If the app is already installed you can also use the scanner option
