Sony was one of the last few smartphone manufacturers to still have compact-sized Versions in its lineup.
The business used to launch small-sized variant s of its flagship using the Compact branding appended to it. Looks like things are about to change as none of the newly established smartphones had a Compact version. We were expecting Sony to establish a Compact model since nearly all of its smartphones have a 21:9 aspect ratio display making them taller and more difficult to interact with when using with one hand.
Fresh rumours hint that the Compact models will no longer have flagship hardware but will probably be mid-range devices, one such example is the Xperia 4. Based on the rumours on Esato Forums and an image that contrasts the newest Xperia 4 to elderly Xperia Compact models like the Xperia Z5 Compact and the Xperia XZ2 Compact. The alleged Xperia 4 is said to be 65mm wide but is taller in 149mm since it’s a 21:9 aspect ratio.
Most Compact smartphones were launched with the elderly 16:9 aspect ratio using the Sony Xperia XZ2 Compact being the exception with a taller 18:9 ratio display.
The alleged Xperia 4 is thought to be 8.3mm lean but will lose out on a 3.5mm headphone jack. Rumours also point the Xperia 4 will be exclusive to NTT DoCoMo in Japan. If these are accessible in different areas of the world remains to be seen.
