What’s the use case for microSD slots on phones these days anyway?
If it’s (just) to avoid paying Google or Apple storage fees, you can work around that by buying one or several HDDs to keep at home and sync stuff over the local network, possibly even build a server and access your stuff remotely.
I really don’t understand the need for that much space on the go, though. Are you watching entire series on your phone?
I understand all of that and I agree with you. Not wanting to pay monthly storage fees is perfectly reasonable too. I know I did everything to avoid giving Google any money for storage.
But microSD slots on phones aren’t coming back, and manufacturers are giving you 512GB of internal storage at most, so we need to move on with the times.
I don’t have a home server (yet) either, but I do have 2 TB disks I use to store all the important stuff I want to save forever. Nothing lives on my phone so I’m fine with 128GB.
Local syncing can be done just by installing Syncthing or Omnisend, and everything gets transferred through your home Wi-Fi. No need for complicated setups. I mentioned home servers as an example but you certainly don’t need one.
MicroSD cards also die so I don’t know why you used that as a slight against internal phone storage. You should always have backups.
Storage is dirt cheap these days, it makes no sense to hinder yourself buying niche phones, often at inflated prices, just for a feature that is easily worked around. In my opinion.
