by 3 Comments

Top 6 disappointments of Galaxy S21 UltraGalaxy S21 Ultra is Samsung’s only hope to reverse the declining sales of Galaxy S phones since Galaxy S10. But it seems Samsung lost the opportunity due to the numerous disappointments of Galaxy S21 Ultra.

This post summarizes the top 6 disappointments of Galaxy S21 Ultra: curved screen, no micro SD card support, lack of essential accessories, no 45W superfast charging,  with S Pen support but without an S Pen, inferior under-display fingerprint sensor.

Curved screen

Since Galaxy S6 Edge (or even Galaxy Note Edge), Samsung tried hard to sell the curved screen.  It is unique.

Unfortunately, Samsung is too stubborn and try luck on the most important flagship phones.

On the three Galaxy S21 models, Galaxy S21 Ultra is the only one with a … Read the rest
