This could be interesting – a Sony Xperia Compact with a tall aspect ratio screen. This is just conjecture based on dimensions from an FCC certification, but the numbers are lining up beautifully.
The Xperia in question has a 5″ screen (126mm) and measures 135.43 x 64.63 mm. For comparison, an Xperia XZ1 Compact is 129 x 64mm – same width, but shorter.
The FCC only gave the display diagonal, not its aspect ratio or sides. However, check out what happens when we compare a 4.6″ 16:9 screen (like that of the XZ1 Compact) and a 5″ 18:9 screen:
Would it be too optimistic to think…
