Google Nexus 5X and Nexus 6P support full manual camera controls19
What some may not like about the cameras on the Nexus 5X and Nexus 6P is that the interface (Google Camera) is a simple one, without many of the advanced controls that other smartphones have. However, in case you were wondering, both new Nexus devices support full manual controls: focus, white balance, ISO, shutter speed, and even RAW support (this doesn't come as a surprise at all, since they're using Google's Camera2 API). What this means is that, although the pre-installed camera app on the 6P and 5X doesn't take advantage of these manual controls, you can always download a third-party app that can.
