The S10 series looks way better and the camera module looks better as well. I don't know why they got rid of the heart rate sensor, I know not that many people used it, but like it's always good to have it. I have a Gear S3 by the way. Maybe cause people would just buy the watches to use the heart rate sensor.
I think the best update Samsung could make is to guarantee an extra year or two of software support. honestly at this point their hardware is so good it doesn't make sense to only have two years of software support (user interface). As much as I enjoyed the launch yesterday I wasn't really impressed by anything because I already have a great device. I'm sure the display rate and camera will be amazing to play with but I personally can't justify the additional expense.
"Samsung broke tradition. Instead of phasing out last year's flagships, it's cutting the prices for the S10s, so they now start at $599 instead of $899.99. That means you can continue to buy the S10e, S10 and S10+, which are still great phones. In fact, the company's Senior Manager of Smartphone Product Strategy, Caleb Slavin, told Engadget, "The S10 is going to be our new entry point into the flagship lineup." He added, "It's a great way for a consumer to get a premium device at an accessible price point." -From Engadget
