I know this is a non-issue for many, but those emojis look really dated. Every update they get harder and harder to read in small form. One of the things I observe, mainly on Instagram Stories is only people with iOS post with emojis attached, I never see Android ones. Too bad there is no way to install custom emojis in any system (without rooting/registry tweaking), like we do with fonts.
Personally, I find it kind of ridiculous that new emojis are considered flagship features of mobile OS updates. I'd think that it would be possible to decouple emoji updates from kernel/security updates, so I imagine that Android/iOS tie them to the OS updates solely as a way to motivate non-technical users to update.
"All current iOS emoji will now work on my phone" was genuinely a highlight of the Nougat update for my Galaxy S7 .
