Frequently Asked Questions
Description
Overview & Display
The Samsung Galaxy M21s presents a familiar design with a glass front protected by Gorilla Glass 3, a plastic back, and a plastic frame. Weighing in at 191 grams, it feels substantial in hand. The 6.4-inch Super AMOLED display is the star of the show, boasting a resolution of 1080 x 2340 pixels and a smooth 19.5:9 aspect ratio. With a peak brightness of 420 nits, the screen promises vibrant colors and good visibility, even in brighter environments. The screen-to-body ratio of 84.1% suggests an immersive multimedia experience, ideal for watching videos and browsing the web.
Powering the Samsung Galaxy M21s is an Exynos 9611 chipset, paired with either 4GB or 6GB of RAM. This combination, coupled with internal storage options of 64GB or 128GB (expandable via a dedicated microSDXC slot using eMMC 5.1 technology), should handle everyday tasks and moderate gaming with ease. Running Android 10 with One UI 2.5, users can expect a familiar and intuitive software experience. The octa-core CPU, featuring a mix of Cortex-A73 and Cortex-A53 cores, provides a balanced approach to performance for smooth daily multitasking and application usage.
Camera & Battery
The rear camera array on the Samsung Galaxy M21s offers versatility. The primary 64MP sensor, featuring PDAF, promises detailed photos in good lighting conditions. An 8MP ultrawide lens expands the field of view, allowing you to capture more of the scene. Video recording capabilities extend to 4K@30fps and 1080p@30fps, with gyro-EIS for stabilization. The auxiliary lens adds further photographic options, though its specifics aren't detailed. The inclusion of HDR and panorama modes expands creative possibilities.
For selfies, the Galaxy M21s features a 32MP front-facing camera with HDR support. This should deliver detailed and well-exposed self-portraits. Video recording on the front camera is limited to 1080p@30fps. The large 6000 mAh battery is a significant highlight, promising extended battery life for typical usage. While it supports 15W wired charging, it's not the fastest available, but the large battery capacity should compensate for that. Expect a full day of use, and potentially longer, depending on your usage patterns.
Who Should Buy This
The Samsung Galaxy M21s is an excellent choice for users prioritizing a large battery and a vibrant display without breaking the bank. It’s well-suited for those who frequently consume media, browse the web, and engage in moderate multitasking. Individuals seeking a reliable and feature-rich smartphone for everyday use will find a lot to appreciate. However, users who demand the absolute latest processor, fastest charging speeds, or NFC capabilities might want to consider alternative options. The Galaxy M21s targets budget-conscious consumers seeking a balanced and capable device.
