Our Samsung Galaxy S21 Ultra 5G Review
✅ Reasons to buy
- Design: Sleek design and matte finish (which helps prevent smeary fingerprints).
- Camera: There is a huge camera unit on the back of the phone, which means the phone has five lenses. Of the S21 series, the Ultra has the best image quality in low-light. It can shoot 4K video at 60 fps. * Director view shows a live feed from the cameras and allows you to switch between them while recording video, single take mode automatically turns 15 second videos into photos, shorter videos, and gifs you can share with others.
- Supports the S Pen: Among the first Samsung smartphones compatible with the Galaxy S Pens (sold separately). Using the pen can help you better navigate the features of this smartphone.
- Intelligent Battery: Maximizes battery life by learning how you interact with the phone and adjusting how much battery is used.
❌ Reasons not to buy
- Price: Even with special offers, this phone is expensive.
- Camera Setup: Navigating the many camera features can be confusing
⚖️ The Verdict
It’s difficult to find something wrong with the G21 Ultra 5G. From its sleek design and improved security to camera performance and increased function, you will love Samsung’s 2021 flagship phone.
