Pixel 2 was a mess (lousy screen), Pixel 3 is a joke.
But in all honesty, I really doubt OP6T will be the camera phone. OP6 has very good camera, one of the best. But that camera can't compete with iPhone/Pixel/Samsung. Great camera indeed, but not one of the best.
Anyone expecting they can change that in 6 months is being really optimistic. Will it be better? Probably. But the funny part is, OP usually doesn't have great camera at launch. OP5 had worse camera then OP3T, after 2-3 updates it was better. Same thing with OP5T and OP6. I'm expecting the same thing to happen with 6T.
It's funny that OP makes the same mistake year after year. Yeah, they fix that camera, and they really put a lot of effort into that fixing. But reviews are already out, and the camera has already been judged. No fixing can help that.
But anyone can install port of gcam on OP phones, and get almost Pixel like camera without a fuss.
