Description

The Samsung Galaxy S21 128GB Gray 5G is one of the few smartphones that combines a lot of computing power with a handy size. The device has a 6.2-inch Full HD screen that you can easily operate with one hand. The screen refreshes 120 times per second. This makes animations look smooth during games, for example. Thanks to the powerful Exynos 2100 processor and 8GB RAM, you can use the most demanding apps and 3D games without any problems. The 128GB storage has enough space for your apps and files. With the 12-megapixel standard camera, you can take sharp photos and 8K videos both during the day and in low light. Use the 64-megapixel telephoto lens to zoom in up to 3 times without your photo losing sharpness. The 4000mAh battery lasts a little less than a day with average use. Do you use the device more often? You'll sometimes have to charge it during the day.

Note: Samsung doesn't include a charger. Purchase a separate Samsung 25-watt charger to charge your smartphone at lightning speed.

I've had the Galaxy S21 5G for about a week now. The switch to Samsung is very nice again, after having had a different brand for 2 years. All functions are incorporated in a menu so that you can quickly use the phone. Because you can set many functions, you can customize the phone to your liking. Think of the night function of your screen, which offers extra comfort for your eyes (the blue tones are limited in the evening). There are so many more functions. I am most pleased with the camera. The "single take" function allows you to get beautiful photos or videos. You film for 10 seconds and the phone then selects the best photos and videos. Within a week I have already had great results with this. The phone works quickly and is easy to operate and is also easy to use for my work. A small disadvantage: due to the powerful fast processor and the beautiful fast screen, the battery runs out quickly. I sometimes find it difficult to get through the day if I also use my phone a lot for work, but just briefly on the charger and you can go again for a while. I am also very pleased with the design of the phone. You have a phone that everyone recognizes with the camera that is processed to the edge. This gives you a phone with a new look that other people are talking about (nice to brag about having the latest Samsung!)
I recommend this phone to everyone, but would you like a bigger battery? Then you might want to go for the Galaxy S21+ 5G.
