The S21U looks nice. I wasn't a big fan of the early renders but I like it. Like the matte options. I imagine the 2nd gen 108 camera system is going to be better, like the idea of the 2nd FPS. REALLY love the flatter screen. But not interested enough for me to move away from the N20U.
I don't mind the chunky look but I'm still loving the thinner more squared profile. Especially the thinness. Most people probably won't notice the difference because they rock thicker cases but love my LaterCase being able to keep the thin profile and given me enough protection for me.
I don't have any issues with the FPS so 2nd gen is nice but probably won't be a major reason.
The S20U had a 5000mah battery so nothing new there and I just spent the week flying and traveling for work texting all day, using GMaps daily to get me around an unfamiliar state and gets me back at the hotel at night with battery left... and I'm usually a 80-90% to 30-20% charge kinda guy (90 to 20 when I'm traveling to make sure even though I keep a battery pack).
Our N20U has the same 12gn RAM the "base" S21U has so not missing anything and I wouldn't go 512. I think I'm running the same 128GB SD that I had on my N8 but if I want more memory I could easily have more than 512GB with a sim swap that the S21U can't.
Don't run my phone at 120hz at WQHD+ anyways so not a big deal. I went back for weeks 120 on and off and WQHD+ and lower and honestly I don't notice enough difference so I keep the lower settings to save battery. Now it our N20Us CAN run 120 @ WQHD+ (on the SDragons) if Samsung wanted to and gave us an update. They didn't because the Exynos can't so didn't to keep things "even." I'd like them to give us an update so we have the option... but Idon't think Samsung works that way and rather try to push you to the newer phone.
Anyways, I think those are a few reasons, for me, I am not interested in to moving away from the N20U. I'm committed to stay with this phone the next few years but if I were to move, I'd wait to see if there was a N21U or S22U.
One more reason... for those that really use the S-Pen on the N20U (I haven't really), the S-Pen on the N20U is still on another level better than the S21U... and fits nicely in a silo. AND has that addictive clicky thing at the end.
So the specs are out... But first i want to thank Samsung for the almost identical design xD so if i do change my wife wouldnt know... But the problem is that in Indonesia it costs USD$285 less than the iPhone 12 Pro Max 512GB... For me it isnt a big difference and its just crazy. Trying to be like Apple...
Few things i like about the S21 Ultra is the 2nd gen 108MP camera module, 10X Optical Zoom, the 5000mAh battery, the 16GB RAM variant 512GB ROM varian and the ability to use 120Hz even with WQHD+...
But my N20U is only 3 months old... And i dont seem to have an issue with it other than the very slow updates. Im still on A10... Should i get the S21U or wait for the N21U? As im never an S Series fan... Never had an S series last longer than 2 months... The shape really isnt my liking... XD
