What do you mean by "have better support for cross-OS applications"?
What other file functionality do you need on a mobile phone?
I want spywares/adwares to be allowed without any restriction so I can install a adblock pro to block them.
It's the same gripe I have with iOS keyboards, unless something has changed there. The feel and layout of every third party keyboard is the same as the default keyboard. During my short period with an iPhone I gave Gboard for iOS a try, tweaking it as much as I could to get a similar experience to what I was used to on Android. In the end it still felt like the system keyboard more than anything.
And the "long-press top row for numbers" option wasn't available so had to switch back and forth between keyboard and "numpad" when typing something like passwords or strings with a lot of numbers.
And the default SMS app being fine? Such an annoyance every time I had to use it. Don't remember specifics (as I was just trying to get away from it ASAP) but there was at least some kind of cringy emoji bar always visible.
Horrible experience all in all and I'm so glad to be back on Android.
For a lot of people, it comes down to being to run uBlock Origin/cosmetic and dynamic ad and content blocking (e.g. not a simple blacklist) and running other extensions and customizations.
It lets any third party messaging system become a viable SMS replacement (like Hangouts and Signal does on Android), by making it seamless to send all messages from one app.
Like iMessage and only iMessage does seamlessly on iOS, because Apple has given it a monopoly on handling SMSes.
It’s anti-competitive as fuck.
Choosing Signal over iMessage. Signal can serve as your primary messaging app, prioritizing the Signal protocol but falling back to SMS as necessary per contact.
Except that it can’t, because iOS won’t route SMS to it.
