S21U was/is an awesome device
I have used it daily for over five years. Sure, it's nowhere near as fast as some of the later S-phones but it's smooth and the screen is crystal-clear and bright. But the battery is beginning show its age and it's no longer receiving updates, so I'll reluctantly have to retire it in a few months when the S27U comes out. Hoping Samsung addresses the PWM issues that seem to have caused the screen issues in the S26U but, if they have I'll be a customer. Truth be told, however, if they put out a version of the S27U without a privacy display at all but with all the other planned improvements, I'd be all over that in a heartbeat. Anyway, I just wanted to give some much-deserved praise to the S21U - it's been a real flawless workhorse for 5+ years.
