The Samsung Galaxy S21 and S23 are two such innovative smartphones that have captured the attention of many consumers. In this article, I will be comparing the Samsung Galaxy S21 vs S23.

The Samsung Galaxy S21 was released in January 2021, while the Samsung Galaxy S23 is still in development. However, there are already rumors and speculations about its potential features and improvements over the S21. One of the most notable rumors is that the S23 will come equipped with a foldable screen, which would be a significant jump in technology from the S21’s traditional screen.

When it comes to the S21, it boasts a 6.2-inch screen, 8 GB of RAM, and a 4,000mAh battery, which provides ample power to last throughout the day. It also comes with a 64-megapixel camera, capable of capturing stunning photos and videos.

Design and Display Comparison between Samsung Galaxy S21 and S23

The design and display of a smartphone plays a crucial role in determining its usability and appeal. In this section, I’ll examine and compare the design and display of Samsung’s latest flagship phones, the Galaxy S21 and S23.


The Galaxy S21 and S23 are both visually stunning devices, with a sleek and modern design that’s guaranteed to turn heads. However, there are a few subtle differences between the two phones.

The Galaxy S21 has a glass front and back, with a metal frame in-between. It’s available in Phantom Gray, Phantom White, and Phantom Violet color options. The camera module is integrated into the housing of the phone and sits relatively flush with the back panel.

On the other hand, the Galaxy S23 has a slightly different design. It still has a glass front and back, but instead of a metal frame, it has a titanium frame that gives it a more premium feel. It will reportedly come in Phantom Black, Phantom Silver, and Phantom Pink color options. The camera module is more prominent and has a unique design that sets it apart from S21.


The display is an area where both the Galaxy S21 and S23 shine. The S21 features a stunning 6.2-inch Dynamic AMOLED 2X display with a resolution of 1080 x 2400 pixels. The S23 is rumored to have a slightly larger display, possibly up to 6.5 inches, and will likely use the same AMOLED technology as the S21.

Both phones have a refresh rate of 120Hz, which is ideal for smooth scrolling and fast-paced gaming. In fact, the display is so good on both phones that it’s difficult to say which one is better.


In summary, the design and display of the Samsung Galaxy S21 and S23 are both impressive. While the S23 has a few notable design differences, both phones are visually stunning and feature some of the best displays on the market. If you’re in the market for a new phone and can afford it, either the S21 or the S23 would be an excellent choice.
