As a fold user myself since the Z Fold 5, I for one welcome the camera upgrades in the upcoming Z Fold 7. Its long overdue. I also agree that there is no reason for their NOT to be a formidable camera upgrade in the upcoming S27.
What I sincerely wish these companies would do is the LISTEN, truly listen to their consumers. You obviously cant make everyone happy and their in the business of making money; granted. However, nobody I know of has been asking for thinner phones. The latest focus to make their flagships thinner just to compete with what apple is doing... (which BTW, have behind the curve of innovation arguably ever since Steve Jobs departed us) is simply holding back on innovation. Thinner means less space for meaningful upgrades, less cooling capacity, etc, etc...
I think, I hope, I speak for the majority of the community when I say "we want" larger battery capacity, better camera sensors, better screens and or more efficient processing power... not thinner phone just to slap a case on them anyways to protect your investment.
