I have a problem with the current width of phones. It's not enough. The aspect ratio too high for use as a phablet.

Actually, it was enough back when I had a Huawei Mediapad X1, with its 7" inch 1920x1200 display. When it came time to replace that aging phone, I couldn't find anything similarly wide.

I ended up with a 7.2" Huawei Mate 20X, which despite its longer diagonal, is significantly less wide.
