The Xiaomi 14 is part of Xiaomi's new generation of premium smartphones and, at 6.36 inches, just as compact as its predecessor. The elegant metal and glass casing houses the Snapdragon 8 Gen 3, which provides plenty of speed. The Xiaomi 14 also scores points with its 3000 nits bright AMOLED display, very long battery life and its Leica-branded cameras.
So not a phone from 10 years ago, one from earlier.
Similar in size to a Nokia 3310 from 2000? H: 113, W: 48 therefore diagonal size is 123mm or 4.8/4.9 inches.
To me it seems like there’d be a severe usability penalty there, but if that’s what you want.
