Unihertz specializes in small phones. They aren't flagship spec but they are midrange at sensible prices. They also have keyboard phones and even a phone with a built in DMR radio for Amateur and GMRS use.
Not a plug, I don't even own one I just love that they are daring to be different.
This has been my experience as well. Fedora KDE is easier and more intuitive than Fedora GNOME on my Surface Go 2.
There’s a company called Unihertz that sells a line of keyboard Android phones similar to the last batch of Blackberry models. I know it’s not slider phones but they are inexpensive.
There is also Planet Computers which makes sliding Qwerty phones but they are expensive.
Same here, 6'4" and size 12 or 13 US depending on how they are made. I have a hard time finding shoes that fit well, I seriously feel for OP.
My cousin is 6'8" with size 15, he also has a hard time finding good shoes as well as other clothes.
