Welcome to the world of Samsung. Several patch came out shortly after I got my S10+ and while it could search for them, tell you they were there, none of them could be downloaded via Data. It seemed, no it still seems odd to me, that this would be the case. Sure most people have WiFi or access to it somewhere but surely not everyone. I keep picturing people stopping into their local McDonalds to get the latest version of Android. I honestly don't believe it has anything to do with data limits or even data connections but it just doesn't make sense to me. I don't believe it's the carriers either because I was always able to get updates via data until I got a Samsung.
Oh by the way if you want a good laugh Google this and pick one of the Samsung "forum" threads. They are hilarious, they really aren't but it's fun to see even the users get upset at how stupid the "Samsung Moderators" are. I can't believe they allow them to have the that title, It's the equivalent of calling your pocket terrier general snuff snuff. An undeserved title. Anyway you can enjoy them telling people to turn on download over data and set WiFi to turn off when connection has no internet. That place is a complete waste and I just want their servers to crash every time I get directed there.
It cannot be done. WiFi only. Visit your local McDonalds, Starbucks or where ever you get your unsecured WiFi. Oh and it won't download through a VPN either...
Crash their servers like sparks flying, chips burning up, unrecoverable, can't even be restarted code lost forever crash. I'm now sick to my stomach.
