Verdict

The Samsung Galaxy Tab A 8.4 2020 4G is a compact, budget-friendly tablet featuring an 8.4-inch TFT LCD display with a sharp 1920 x 1200 resolution and a 16:10 aspect ratio. Powered by an Exynos 7904 octa-core processor paired with 3GB of RAM and 32GB of internal storage (expandable up to 512GB via microSD), it offers reliable 4G LTE connectivity for browsing and streaming on the go. Key pros include its highly portable, lightweight design, a crisp high-definition screen that outperforms many competitors in its class, and a respectable 5,000 mAh battery providing roughly 10 hours of usage. However, the device has been noted for sometimes sluggish UI performance during heavy multitasking, poor 2.4GHz Wi-Fi reception, and tinny audio from its bottom-firing dual speakers.
