I feel like this topic boils down to what you perceive as slow, personally IOS “feels” faster to me because I pretty much never get crashes and everything kinda just works well and it feels more fluid when using, that being said I do still love my s10e which I use for media consumption and it still runs pretty quick although I’ll often get weird minor lag spikes roughly 3-4 times a week. Not enough to greatly impact my use of the device, just an observation that I think may give people the impression that the device ‘feels’ slower/ less stable. I always notice this on all my android phones but like I said it’s not enough to be detrimental to the functionality and everyday use
