My S23U (6.8" screen) is easier to manage one handed than the iPhone 13 Pro (6.1" screen) which preceded it, and the sole reason is the universal back gesture.

I’d rate Apple’s customer service as near the top (if not the very top) of every business I’ve ever dealt with. Samsung’s customer service, on the other hand, is truly appalling and quite possibly the worst of any company I’ve ever dealt with.

Samsung really need to improve, but I can’t imagine it happening.
