I know there used to be such a huge range of Android phone sizes, that there was likely to be a phone in the size you wanted, and you acknowledged that the phones you were listing were not the same size as the 12/13 mini...
But the Sony suggested is slightly bigger than the iPhone 16 in 2/3 of the dimensions and this comment thread is lamenting how big the iPhone 16 is! I think people who see the iPhone 16 as so large it is not an option are unlikely to consider switching to Android for an even larger phone.
It's a shame, because Sony used to make smaller phones with only slightly lower specs than their flagship phones. I also still associate them with making sensibly-sized alternatives, even though they don't anymore.
