    A totally brilliant phone..

    I have had Samsung since the S3, usually miss one generation. This time leave behind my brilliant S10+, still working brilliantly.. The S21 Ultra is a step up, the battery life is amazing at nearly 2 days with gaming and video and everything set at max. The screen is beautiful, as is usual with Samsung (best of any).. Sound is also fabulous, the speakers are really clear and atmos is amazing.. The cameras are also top notch, with high class video too.. NO SD card slot, now that is really annoying and would been an easy thing for them to fit in.. I think this a fantastic phone with a lot to than I have written here.. Buy one you wont regret it..

    Excellent phone but.....

    I had taken the iphone 12 Pro Max as an upgrade deal and almost immediately regretted it. It was just a poor phone in comparison to my previous Note 10 plus. So I sold it and used the money to get this handsome gadget.of a phone. Display is clear and sharp whilst it is super fast responsive to commands. My only only gripe is the rather poor battery life. The Note 10 used to last a lifetime on a single charge. The S21 Ultra however needs charging by the end of a day's use. But even with this small niggle I am still a lot lot happier owning it than I was the clunky iphone 12 Pro Max.

    Great camera and display. Quite large.

    As with most phones of this generation, it is quite large with a large clear display. Apart from its size, the main difference from my previous Samsung J5 is the camera which is excellent for both stills and video. The GPS works well with my OS Maps app, showing me exactly where I am on the map. I do miss the FM radio on the previous phone. Listening to radio over the internet is not as good because of drop-outs while walking the dog.

    A great phone so far.

    I haven't had the phone long enough to try out all of the features, but up to know it is all I hoped and wanted it to be. The battery life is excellent at 2 days (I don't play games), it looks and feels feels great. The camera features I have tried so far have given excellent results and the fingerprint reader is lightening fast . Still learning.

    Camera is awesome, just need a while to learn how to use it...

    This phone is awesome, fast and has some great features. Online it has had mixed reviews for its camera. From what I can see (day one of having it) you are given a lot more control to get the perfect photo but you will need to train yourself I how to use all the settings in the best way. Overall very happy with it!

    SAMSUNG S21 ULTRA, GREAT PHONE!

    Probably the best mobile phone I have ever purchased! I bought this to replace TWO phones; the first being my Samsung A12. The second, my Nokia Lumia 1020, with its 41mb camera. The S21 Ultra, is remarkable - it has everything you need from making calls, taking notes and of course, the camera. Best to read a professional review to see all the details!

    Great Camera.

    A great phone, superb camera but don't rely on the 8k recording feature. This setting is very limited as you cannot use 8k settings with all the lenses, but only works with one of the Lenses and limited settings. The best setting is 4k on uhd at 60fps 16x9 picture format, then all the lenses can be used with a good resolution.

    One of the best but not the bestest.

    Battery is good but not the best. Fast processing but not as good as snapdragon varient as i used that too. Camera quality is good too but again not as good as snapdragon. Play store updates goes fine but when installing the update most of the time takes very long if i compare with huawei, oppo etc.

    very impressed

    Like a brick. Its a very powerful phone, literally a computer. Cameras are outstanding as well, so many of them, one 108 mega pixel. Was in great condition for price. I don't buy latest models, but this was a heck of an upgrade, and hard to imagine needing anything more from a phone.

    Samsung they know what they are doing.

    Had my doubts upgrading to S21 Ultra from my S20 5G but glad I did. The screen and build quality is why Samsung are thenleaders in Android phones. Handtec are a great company to but refurbished items from a d with the eBay code I saved £45 off the price.
