I’ve had two different unihertz models, and neither of them could stay on any wifi, and both of them dropped calls like crazy. I contacted customer support, and they ‘offered’ to swap for another exact same phone, if I paid to ship both ways, and I didn’t mind having no phone for a month. Jelly 2, and Atom XL. The Atom was especially bad as it has a giant bloody antenna sticking out the top of it, and still no WiFi!
Avoid Unihertz.
Steam and Lutris work well! I can game on XFCE Mint just fine. I actually have an easier time of it than on a number of distros, thanks to the combination of flatpaks and the Ubuntu base. But, I am not “the kids”.
