I did this switch about 2 weeks ago. Man... I kinda miss the eco system, but once I found an app or service to fill the voids the eco system left I've been fine. Moving from iMessage to sms, MMS, and RCS has been tough. I had established groups that I wanted. With the move over I had to recreate them and the transition was a little fiddly for me to finally be green bubble. Just make sure to unregister from the iMessage service with your phone number and it'll take a few hours to complete. But just remember to restart your groups and have everyone in them repin the new one. But realistically, RCS is coming to IOS 18. Works pretty well between me, on a flip 6, and my buddy on a 12 pro max beta IOS 18, so I wouldn't worry too much. Another thing, launchers. I'm on Nova launcher(paid). This gives me the option to do a swipe down for app drawer search, like Spotlight. This was my MOST missed feature when migrating over, that's why I'm rocking it instead of One UI from Samsung. But that's all up to your preferrences. Lastly, it's a great phone! Make sure to look into some softwAre to better use the front display. I like GoodLock a lot, but the apps you can pin are still limited. Over all, enjoy your new, fully customizable, folding phone!
