Haven't the early problems with the Pixel 6 models been largely remedied? By the time I bought mine in April, it seemed that the most frequently cited issues had been addressed and resolved. Based on my own experience and the reports I've seen from others here, the Pixel 6 devices generally appear to be providing excellent, reliable service, at least since the middle of the model year. One could fairly complain that the phone should have been less problematic when released; but at this point, I don't see why Google would discount the value of the Pixel 6 line beyond normal measure as a trade-in.
I would say everything but the subpar connectivity is fixed on my P6. Still lose data connection in many places my work iPhone has full service. It is a little better, but I guess they have pushed the software as far as they can. It is simply a not good modem.
