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