Am using an S8 atm, and have access to an S10 sometimes. Experience is better, but not vastly. This is not something that IMO would be worth X2 the money.
Is that S8 upgraded to latest OS?
Because I really don't see how the experience "is better".
It's like switching from a 4790K to a 7700K. It's newer, it's faster, but the difference is so tiny that you can't really notice it.
And to be honest, I feel that S10 is a step back somehow. S8/S9 had that Iris sensor, and also a color illumination sensor on front on that top bar.
Both are gone in all variants of S10. What is gained is a depth sensor on S10+, but both S10 normal and "e" are inferior in terms of sensors.
Even worse, Unbox Therapy and others have proven that S10 can be unlocked with a simple photograph on another phone. That's BAD, really bad.
The Iris sensor on the other hand is very hard to trick, needs special equipment to simulate the reflectivity of human irises in infrared light.
And if someone doesn't care about fingerprint sensors (for whatever reason), the back placed fingerprint thing on S8/S9 are simply not relevant. I for one never used it.
I feel that too many sacrifices have been made for the sake of the larger screen to body ratio.
/pass this gen, sorry but waiting for something different.
