Samsung Galaxy A21s features a 6.5-inch (720×1600 pixels) resolution with an in-display fingerprint sensor. It is powered by an  Octa-core processor, which is powered by Exynos 850. There is up to 4GB of RAM and 64GB of ROM  of inbuilt storage, and a microSD card dedicated slot as well.

Samsung’s Galaxy Note series started out as business-focused devices, promising tools for productivity including the instantly familiar S Pen stylus. The series has been recognized, and often derided, for pushing screen sizes though what seemed impractical a few years ago is now quite mainstream. Of late though, Samsung has turned the Galaxy Note series into a premium flagship lineup, with a roughly six-month gap between Galaxy Note and Galaxy S series launches.

This year’s Galaxy Note 20 series is being billed as “the best of the best”, with all the latest features and specifications, plus of course the S Pen. There are two different models like last year.

This is, first of all, a very large phone. It has a 6.9-inch screen, and narrow borders don’t help a lot when it comes to reducing bulk. At 208g, the Galaxy Note 20 Ultra is a bit heavier than average but it’s the bulk and overall shape that make this phone difficult to use. The top and bottom are completely flat, while the sides are rounded. I found the lower corners digging into my palms when holding this phone.

Samsung Galaxy A71 has finally released with Samsung Galaxy A51 in the month of December 2019. The Galaxy A71 comes with a bigger screen 6.7 inches Super AMOLED capacitive touchscreen with Corning Gorilla Glass 3.
The Galaxy A71  has 6 GB RAM with 128 GB internal storage. Although, the internal storage can be increased with the help of a microSD card up to 1 TB.
The smartphone feature a quad camera on the rear side 64 MP (wide) + 12 MP (ultrawide) + 5 MP (wide) dedicated macro camera + 5 MP depth sensor.
The front camera there is a 32 MP (wide) for clicking super selfies that feature HDR. There is an active noise cancellation with a dedicated mic along with a 3.5mm jack.
It also features GPS, NFC (market dependent), Bluetooth 5.0, FM Radio, and Type C USB. It is fueled with a non-removable Li-Po 4500 mAh battery that provides Fast battery charging 25W.
The Samsung Galaxy A71 runs on the Android 10.0 operating system with One UI 2. There are various colors available such as Prism, Crush Black, Silver, Blue, and Pink.
