From what I understand, 28th will be the launch dates for network/carrier mobiles, then as the roll out continues, unlocked phones will be in line for an early April update.
This, of course, could change. But the good news is we're literally a day from a new update.
Just watched this myself @macsafe73, and I have to say that I am pleasantly surprised by how many AI goodies will be coming to the S23 Ultra within the next few days. In many ways it will be like getting a whole new device!. Something to get excited about for sure. Any S23 Ultra owner getting this update would really benefit from watching this video and any other tutorial video out there, such is the importance and magnitude of this update. Hope we all enjoy our new S23.5 Ultra's when the update drops..😛👍
