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 announced its latest Samsung Galaxy A3 Core smartphone. Which comes with a 3000 mAh battery, as well as an aggressive price tag for its budget specs and features. It is in three colors – Black, Blue, and Red. 

Camera and Display

Galaxy A3 Core has two cameras on the back. The one you will probably be using the most is the main 8 MP, f/2.2, AF camera lens. AF denotes Auto Focus. Interesting to see that it shoots 1080p@30fps videos and has an LED flash for enhanced photo lighting. The second camera is the selfie camera which is an 8 MP, f/2.4 shooter.
It is a compact smartphone which measures 141.7 x 67.5 x 8.6 mm in dimension and its has 5.3 inches display to cements this fact. At 150 grams it surely is one of the lightest smartphones you can buy. The display of Samsung Galaxy A3 core has 720 x 1480 pixels resolution and it is a PLS TFT capacitive touchscreen.

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.
