That seems odd, you reset it after encountering that? I still have an S8 in my drawer but upgraded to the S10 when it came out last year and I honestly can barely tell the difference in their performance (I don't really mobile game so no idea there). I was actually really disappointed that it didn't feel like I'd just upgraded to a new model Corvette but felt like I got a car wash, which is how I'm sure all my phone upgrades will feel after the S7 now.

I had a big performance problem on my s7 way after putting in a high speed SDcard that apparently was corrupted or damaged. I was only, as far as I know, who knows what Android was storing on it, putting podcasts/images on it and it still brought my entire OS to its knees until I removed it. That was a huge trial in my Android loyalty because I went months with this incredibly slow phone until I finally was packing it up to sell, remembered "oh I don't want the buyer to have my SDcard!" pulled it out and it felt like a new phone again, I got another 2-3 years out of it. Eventually tossed it at the ground on accident thus the s8..
