Samsung Galaxy M21s Price and Accessibility Review
The Samsung Galaxy M21s is priced at around $250, which makes it an affordable phone that is accessible to many people. It is available in many countries around the world, including India, Brazil, and several countries in Europe. The phone comes in two color options: black and blue.
Samsung Galaxy M21s Design Review
The Samsung Galaxy M21s has a plastic body, which is pretty standard for phones in this price range. However, the phone looks and feels premium, thanks to its glossy finish and smooth curves. The phone’s dimensions are 159.2 x 75.1 x 8.9 mm, and it weighs 191 g, which makes it a bit bulky. It has a rear-mounted fingerprint scanner that is easy to reach and fast to unlock the phone. The phone also has a USB Type-C port, a 3.5 mm headphone jack, and a dedicated microSD card slot.
The Samsung Galaxy M21s features a 6.4-inch Super AMOLED display with a resolution of 1080 x 2340 pixels. The display is bright and vibrant, and it has excellent viewing angles. The phone also has a small waterdrop notch that houses the front-facing camera. The bezels around the display are relatively thin, which gives the phone a modern and sleek look.
Samsung Galaxy M21s Camera Review
The Samsung Galaxy M21s has a triple-camera setup that consists of a 64-megapixel primary sensor, an 8-megapixel ultra-wide-angle lens, and a 5-megapixel depth sensor. The camera takes great photos in daylight conditions, with plenty of detail and accurate colors. The ultra-wide-angle lens is handy for capturing landscapes and group photos. However, the camera struggles in low-light conditions, producing photos that are grainy and lack detail. The phone’s front-facing camera is a 32-megapixel sensor that takes sharp and detailed selfies.
Samsung Galaxy M21s Performance Review
The Samsung Galaxy M21s is powered by an Exynos 9611 chipset, which is a mid-range processor that is capable of handling day-to-day tasks with ease. The phone also has 4GB of RAM and 64GB of internal storage, which can be expanded up to 512GB via a microSD card. The phone runs on Android 10 with Samsung’s One UI 2.5 on top, which is a user-friendly interface that is easy to navigate.
Samsung Galaxy M21s Software Review
As mentioned earlier, the Samsung Galaxy M21s runs on Android 10 with Samsung’s One UI 2.5 on top. The software is intuitive and easy to use, and it comes with many useful features such as Dark mode, Game Booster, and Digital Wellbeing. However, the phone does not receive regular software updates, which can be a concern for some users.
Samsung Galaxy M21s Battery Life and Charging Review
The Samsung Galaxy M21s has a massive 6,000mAh battery, which is one of the largest batteries in any smartphone. The battery easily lasts for a day and a half with moderate usage, and it can even last up to two days with light usage. The phone also supports 15W fast charging, which is not the fastest charging technology out there, but it is still decent enough to charge the phone from 0 to 100% in around 2 hours.
In general, in day-to-day use, the Galaxy M21 is all right, and it brings to the table everything that a smartphone in this price range should.
