Wait. It was 649 few days ago. How 799 is a deal? Cold. It.costs 799 anywhere.
To be honest, if you can keep it, keep it. The Note 10/20 and S20 aren't as good on battery and performance nor camera compared to Snapdragon and the design of the S21 is better too. Wider fingerprint sensor, better camera etc
Cold not an Apple phone
I just received the said S20 ultra from the £649 Amazon deal a couple of days ago. I'm coming from an S10+ and I must say I'm not that impressed... don't think it's been a worthwhile upgrade. The 100x zoom is overrated, the 120hz screen I can hardly notice the difference - certainly not the "once you go 120 you won't go back to 60" bo**ocks that's been banded about by youtube reviewers.
I watch a lot of YouTube and battery drains and this is right up there with the Snapdragon and outlasts the other flagships on the market. Let's not forget though we are real world users and not be running benchmark after benchmark like they do on reviews. I still got my S9+ and the high refresh rate is like night and day. Camera also top class. The next phone am interested to see is the OnePlus 9 Pro, I think that will be very interesting.
