However, I think the era of small phones as we know it is over for now. The smallest we have is the Mini, and even that isn’t small.
In fact, I think the next version of the small phone will be flip phones. We already see this with the Samsung fold. I tried one and was pretty impressed, and I feel like this is the likely direction the industry may take.
However, I’m using my current phone for the next five or six years. I’m sure by then, the folding screen tech will improve a lot, and apple may even have their own version out by then.
