The Galaxy S21 Ultra is the best Android phone yet with dual zoom lenses, a stellar display and excellent battery life. The S Pen is just a bonus Samsung has nearly perfected the big-screen phone with the Galaxy S21 Ultra.

Dynamic 6.8-inch AMOLED display, Dual telephoto lenses, S Pen support, Great battery life

Pricey, No charger or microSD card, A bit bulky

The redesign, though relatively minor, has a major impact by making the Galaxy S21 Ultra stand out again. The gorgeous adaptive 120Hz WQHD+ display and useful extras like S Pen support make the Galaxy S21 Ultra a joy to use.

The Samsung Galaxy S21 Ultra 5G offers not only a 3x telephoto lens, but also a 10x telephoto lens. As long as you don't use the additional digital zoom, then results can be very good.

New 10x telephoto camera, Consistant results from all cameras, Excellent colour, Excellent range of cameras, Speedy performance and snappy responses

No MicroSD memory card slot, Night mode images can have issues, High price

Well that’s it really. A month into using the Samsung Galaxy S21 Ultra 5G, and most of my opinions about it haven’t changed. It’s still a fantastic flagship phone and despite the few annoyances, this is still one of the best phones I’ve ever used.

I did not get to review the other S21 series, but based on the S20 experience, I think the S21 Ultra 5G would be a choice to go. My reason: the 100x space zoom is the killer feature that are not found in any other phones. Top that with S Pen support.

So all in all, yes, we do feel that the Enhanced Game Booster did bring some improvements to the Samsung Galaxy S21 Ultra 5G. As mentioned, the RAM allocation and processing speed directed to some mobile games proved useful.
