I’d be interested, too. I have a nearly 2-year old S8+, which has been a very good phone. Samsung really got battery religion after their Note disaster. I was concerned that the sealed-in battery would doom this phone, but so far I have not noticed a significant loss of battery life.
S10 will wirelessly charge earpods and watches.
I wasn’t crazy about the S8 because the fingerprint detector is on the back instead of the more convenient front as with the S7.
I’ve had my S7-Edge for 2.5 years and still works & looks great with it’s screen resolution.
As as a phone, it has superb sound quality - esp using my pro-like IEM with Silver wiring.
Throw in the cheap factory fast-chargers for a quick boost and I never worry about a dead phone (S8).
