Most smartphones these days are pretty much alike, with a few exceptions at the top of the range.
The foldable phone seems a breath of fresh air. See the Samsung Galaxy Fold. It looks good, but seems a little chunky, but when opened, could provide the user with a much bigger interface. At the moment, it doesn't seem big enough, but an alternative to a phablet.
Is it just going to a niche with small volume sales, or will it develop to become much lighter and more of a practical alternative to tablet computers?
I understand Google is going to support foldable phones in Android, so there's another screen style for developers to deal with?
