It shows the option with larger files, see screenshot below where I have an image that is +2MB.
If anyone wants to try the Samsung Email app here is the Playstore link:

Agreed. I barely use my iPad for productivity, use it just for Netflix and Amazon Prime in bed or when travelling, iOS still has a lot missing for me to ever solely depend on it for actual work when mobile. Something that I cannot believe iOS still doesn't have is a Multi Item Clipboard e.g. if I am copying different things from different apps (e.g. an article from a website in the browser, a piece of a previous mail and maybe something from my notes app), on my Galaxy Note I can just go to each app, copy what I want and then go to the email app and open the Clipboard paste everything accordingly, much like I would on a PC. I've learnt to see iOS as more of a platform that is good at handling my entertainment, while Android can do both my entertainment and productivity.
