Interestingly, I have the OnePlus 7 Pro with the latest Android 10 Open Beta, the phone is amazing apart from the camera which is so so, also tried gcam but the colours were always off.
Sometimes I could get good pics but on the whole I was never happy, this was especially true when trying to take photos of my 2 & 4 year olds, in good lighting conditions the camera could work well. When the light wasn't optimal (not dark) picture quality was not great.
I took a punt on a Note+ Plus having owned the Note 9 and Pixel 3 XL, I personally find the camera quality much better and I also get far less blurred shots.
I still have my 7 Pro and will keep as a backup, interested tos how they improve the quality as this is the only thing I didn't really like about it. Battery life and screen are amazing.
Pixel 3 is still the picture king, was going to wait for the Pixel 4 but the leaks put me off, I also prefer OneUI gestures to Android 10.
Overall very happy with the 10+, the OnePlus 7 Pro is very close and a few hundred quid cheaper.
