Which is all well and good. However, the two main things I was looking for (both showstoppers for me) were:
- Working 'Super Res Zoom' on the main lens. As it stands, the (slightly) smaller Pixel 6 has this working, but it's MIA on the Pixel 6 Pro - which makes little sense. Without this enhanced software zoom system, zoom is essentially unusable from about 2x up to 3.9x, the very range which is used a lot in day to day snaps of people and situations. Note that I do still think this is a software issue and can be fixed - if Google can be bothered. Come on, Mountain View, take a bit more care over your imaging here.
- Proper Stereo speakers. On the Pixel 6 series, even with this update, the left/right channels are mixed to what I'm calling 'Mono+'. There is a slight stereo effect, it's true, but I still hear lots of right channel in the left earpiece speaker, and vice versa. I understand that Google do this to disguise the fact that they screwed up the earpiece speaker, which isn't anywhere near as loud and clear as it should be. In short, it's a bit of a mess. At least to stereo purists like myself - if you're going to advertise 'stereo' then don't heavily cross-mix the channels!
These were categorically not fixed. Somehow I don't expect Google to fix the latter, but I do expect them to add Super Res Zoom back in. If only to shut me up!
I've now passed the PR review loan device to my podcast co-host Ted Salmon - we'll see if he finds the device more satisfying than me!
