I plan on getting the S22 Ultra as long as there aren't nasty surprises in the unpacked event on 9 Feb. I will not trade my ZF3 though - I will keep that and see what the ZF4 will be like. If they increase the width of the cover screen of the ZF4, then I will likely upgrade and trade in then, but if they do not and it's the same size, I probably will not. I use the cover screen too much and that is really the only issue I have with the ZF4. Unfortunately, a wider cover screen will mean more weight and bulk, but it's something that I think I can deal with just to lessen the struggle of the cover screen with my fat fingers.
I think over the next year or two I will be figuring out what works better for me - the SXX Ultra or the ZFx.... or Samsung's scrollable phone.
I have a feeling next year Samsung will unveil their scrollable phone since they finally showed their prototype earlier this year. I've always had my eye on scrollable phones before fold phones. The disadvantage is the electrical moving part and also exposed bendable screen that I bet they are trying to figure out.
I really am not a fan of upgrading phones every 6-7 months. I did that with the Note and S series for a few years before stopping with the S8+ and sticking with the Note. I don't really like the S series round corners, so I'm glad they retained the squarish Note look for the S22U. But we'll see what they unveil next week. While the specs seem to be an upgrade in just about all aspects over the Note 20 Ultra - we don't know the whole picture. I would not be surprised, for example, if the S-Pen is not bluetooth and doesn't have the extra functions like camera shutter control, etc. The screen is already a little smaller than the Note 20U. They gimp it enough and then I'll just keep my Note 20U and ZF3.
