    The camera on this phone is amazing! My only complaint with this phone is that I don't have a flashing indicator that there is a text waiting. I often leave my phone laying around the house and there is no immediate way to know if I got a text while I was away. The battery life is great and it does what a phone should do.

    I really like the larger size of this phone as it is easier to see written text. There are many great features and I seem to discover more every day. The camera is a plus as it takes amazing pics. The battery life is long even when playing games or using it continually.

    The Samsung Galaxy S21 Ultra is the very best of what Samsung can pack into a smartphone. It wowed us with a huge screen, five cameras and the best zoom on any readily available Android phone. Caution: while it's cheaper than last year’s ‘Ultra’ phone, it remains pricey for average consumers, and it doesn’t come with a microSD card slot nor does it include a charger.

    Galaxy S21 Ultra is the phone to fit all your needs. I always take my time and research all phone options. From the high quality of the phone in every way to the price and value you'll be beyond pleased. Easy to use, lots of great things about this phone but my favorite is the awesome camera and video playback

    This phone is awesome. The pictures it takes are as good as a pro camera would take. The features of the phone are numerous and I haven't even started to try them all. When my wide use to send text massages and pictures with her old S20 5G it would take forever even with WiFi turned on. This one once you hit the send if you blink it is gone.

    I haven't bought a new phone in years since my Galaxy S7. I enjoy this phone because it really does hold charge even into the 2nd day if I'm not constantly on my phone the first day. The camera is stupendous and the speed is very fast. The one flaw for me is the size, I'm a woman and it doesn't fit that great into my pockets. I would have preferred the size of the S21 with the features of this Ultra. But I don't regret it regardless!

    I bought this Samsung Galaxy S21 Ultra to replace my S8+. What a difference. Pictures look great. Optical zoom is awesome. Apps run fast. Love the big screen. Battery last all day. I looked into getting the new Pixel 6 which my friend recently bought, But I think this phone is still better.

    Excellent camera and beautiful silver case color. I have small hands, so this feels much bigger and weightier than my previous Samsung S20 making it harder to use one-handed. However, would recommend to others who wouldn't find the size a problem. Delivered from Best Buy to my front step quickly.

    I bought this phone mostly for the camera features as I take alot of pictures with my phone. I didn't say out to buy this expensive of a phone but I'll say it's worth the money. The pictures and videos it takes are stunning quality. So if you're looking for a phone with great cameras, then consider this one!

    Samsung has being proven that their phones are the best every single year. You are getting quality and the best technology. Always try to get them on sale to save some money, or whenever they're launched to get the best bonus deals and discounts.

    I went from a Samsung Galaxy S6 to the 21 ultra and glad I did. It takes much better pictures, the colors are clearer and brighter. It is heavier than my S6 is the only drawback I have found so far. It is easy to maneuver around just like the S6.
