SONY XPERIA Z5 PREMIUM DUAL
The Sony Xperia Z5 Premium Dual’s camera UI is sparse. If you shoot in ‘Superior Auto’ mode, you can tap to focus, but you can’t change brightness settings. There’s a ‘Manual’ mode, but this only lets you change white balance and exposure.
On the other camera apps, you can set the video resolution to 4K as default, but you can’t do that on the Z5. Instead, you’ll need to go into its ‘Modes’ screen, and tap ‘4K’ video every time you want to take 4K video, which is an inexplicable hassle.
