Customers are saying

Customers are satisfied with the Galaxy S21 5G 128GB's camera quality and battery life, with many praising the excellent picture and video capabilities and long-lasting power. The screen size is also generally well-received, although some prefer a more compact device. However, the lack of a headphone jack and the high initial price point are common criticisms.

    Touch feel is buttery smooth and fast responsive. Screen space is big but still fits right in your palm. Easy to move your thumb across the screen. Only downside is OS is full of applications you dont need, I tried to get rid of lot of apps but you can't.

    Beautifully designed and top of the line specs even a year after launch! Samsung still loads it with bloatware but at least the OneUI interface is much nicer and you can configure the phone settings to your liking. Best of all, this is more compact than the other flagship phones.

    I upgraded from pixel. The picture quality in my opinion was better than what I’m use to. The display is beautiful. Watching shows it way different than what I am use to.

    Best Android for the price, if on sale

    If you can get this on sale, this is probably the best android phone for the price. $500 is reasonable for the amount of flagship tech you get in this. However, I would definitely not get this at full msrp.

    Finally took an effort to upgrade to something more modern... the Galaxy S21. The bezel is thin, and the battery seems to be a major upgrade coming from my old iPhone.

    This phone has a great display, decent camera and video capabilities. Battery also lasts easily for about a day and half with light usage. Just wait and get it for the right deal.
