I used Glasswire before on my rooted phone. I loved the program but alas that phone died and I had to get a new one. The new one is a Samsung A51, and it is not rooted.
The question I have is, “Is it possible to get the full functionality of Glasswire on a non-rooted Android?”
I am guessing I would have to install Glasswire with ADB or the like. Or a side install with Windows. The #1 function I need is to block all but a couple apps on my phone from using the cellular data.
