The Samsung Galaxy A21s offers a great rear camera setup, one of the best software experiences in the industry, and an excellent battery life. While the phone doesn t come with an AMOLED panel, its IPS LCD does the job. The only major complaint with the device is that it has a serious performance issue due to the weak Exynos 850 SoC. If you are a heavy multitasker, you should steer away from this device. However, if you are a light user then the Galaxy A21s will offer you great user experience.
Pros
Rear camera offers 48MP main sensor, 8MP ultrawide sensor
Feature-packed, organized, and neat-looking UI
Up-to-date connectivity options
Massive, 5000mAh battery
Cons
Weak processor
No AMOLED panel
