According to our mobile phone expert
Thanks to the unique camera setup, the Samsung Galaxy S21 Ultra 128GB Black 5G is the top device from the Galaxy S21 series. With the dual telephoto lens, you can zoom in up to 10 times without your photos becoming less sharp. With the 108-megapixel standard camera, you can take razor-sharp photos both during the day and at night. You can store all those photos and 8K videos as well as all your apps on the 128GB storage. The large 6.8-inch Quad HD screen is more difficult to operate with one hand. This screen isn't only sharp, but also smart. The S21 Ultra automatically adjusts the refresh rate from 120 times per second when you're gaming to 10 times per second to save battery. In addition, the device can be operated with precising when you use the S Pen stylus, which you can purchase separately or in the Samsung Ultra Clear View Book Case with S Pen bundle. Thanks to the Exynos 2100 processor and 12GB RAM, the S21 Ultra is one of the most powerful smartphones of the moment. The large 5000mAh battery can easily last a day.
Note: Samsung doesn't include a charger. Purchase a separate Samsung 25-watt charger to charge your smartphone at lightning speed.

The Samsung S21 Ultra is lightning fast and takes very nice photos and videos. The device is quite large and heavy, so I don't always use the smartphone easily.
Nice design, but very big The design immediately catches the eye. Samsung allows the camera island to merge into the side of the device. As a result, it is not so noticeable that there is a considerable block on the back of the smartphone. Because of the cameras, the device wobbles when I lay it on its back on the table. Fortunately, I no longer have this problem with a case. The back of the S21 Ultra has a matte finish, giving the device a sleek look. However, the smartphone is very large and heavy. It barely fits in my pocket and it's difficult for me to operate the S21 Ultra with one hand.
Impressive cameras The cameras perform very well both during the day and in low light. I take really sharp photos with this smartphone. Especially the double telephoto lens really adds something to me. I zoom in 10 times without my photo or video becoming less sharp. So now I, for example, portray a bird without getting close. Handy, because now he doesn't fly away from the fright. Videos are also razor sharp. With the new Director's View mode, I can switch between the standard, wide-angle and telephoto lens while filming. At the same time, I also record with the selfie camera. So I don't have to edit as much afterwards.
Razor-sharp screen The S21 Ultra is equipped with a quad hd screen. By default, the resolution is set to Full HD. After I set this to quad hd I saw all the details of my movies, series and games. Thanks to the high refresh rate, movements in games look very smooth.
Lightning fast So far I have not seen the Samsung S21 Ultra falter once. I switch quickly and smoothly between different apps. This powerhouse also has no problems with heavier apps and games. I play 3D games like PUBG and edit photos in a heavy app like Photoshop without giving the device a hard time.
No charger included, good battery life Striking: for the first time, Samsung does not supply a charger with a smartphone. I didn't have a Power Delivery charger at home with a USB-C connection, so I had to buy it separately to charge quickly. With the 25W Power Delivery charger from Samsung, I fully charge the S21 Ultra in about an hour. If I use the smartphone for a day on average, it easily lasts a day. So I scroll through my social media, whatsapp with friends and watch a movie now and then without worrying about the battery.

It costs something, but then you also have something! The device feels nice in the hand, not TOO big for the name ultra. Battery lasts more than a day. The camera is unbelievably good.
