While it is nice getting Camera2 API, but the implementation of the Pro mode is meh at best. Sure you have access to more settings, but you have no preview of the exposure when you adjust ISO and shutter speed. My ancient S6 has this with its Camera2 based camera (not to mention my newer Samsungs). The default adjustment UI is just in the way. Secondary way of accessing is better. I must say I still prefer the Samsung UI to this, where it has live exposure preview and shows live EV setting. I didn't buy this for the camera, but even then the camera has been a continual disappointment.
PS, I love almost everything else about the phone. NFC and camera, the achilles heel of this phone.
Can someone post images to compare? Thanks
