I think that Apple's 'Mini' sales are a little misleading in the sense that the iphone se is nearly as small, and just as good inside, and has the novel (for Apple) feature of a fingerprint reader when those became prized during COVID. Also, they sell multiple phones at the same price - Iphone 11 with more storage, or iphone 11 pro, or iphone SE with more storage, or iphone 12 mini, etc.
I think Samsung will do ok with a smaller 'base' model, particularly if they can finally return the price to its more natural pre-5G fiasco setting.
I also believe they should make fewer phones over all, and make sure they're all durable reliable as they used to be. I see too many red flags in reviews, touchscreen issues, glass failure, etc. I owned an s8 forever, but Samsung's current lineup is a mess. FE? 21? 20? None of them seem to line up on price vs features any longer.
