As others focus on phablets, Sony showed the 5" market a lot of love with the new Xperia X series. The Xperia X Performance is essentially a Z-phone in disguise. Better yet, not even the Z5 has a brushed metal back.
This one has it all - waterproofing, stereo speakers, a Snapdragon 820 chipset, 23MP worth of still images, the works. If money is no object, this would be our pick.
The Sony Xperia X is the middle sibling. The same metal exterior (without the brushed finish) and 5" 1080p screen, the same still resolution and stereo speakers. It's just not waterproof, though, and the chipset is a Snapdragon 650.
The Sony Xperia XA is for the price-conscious. It still has a 5" screen, but of 720p resolution. No metal finish, no stereo speakers either. The camera obviously took the biggest slash, a 1/3" Exmor RS sensor of 13MP resolution.

Sony xperia x F5122 model 2016 is at my hand. Camera back 23mp and selfi 13mp. Ram 3gb and internal memory 64 GB. Software 6.1 what I've upgraded 7.0 naught. All features are very good but battery is 2620map what is not sufficient for the device.
