This is an affordable Android Go device, so don’t expect anything cutting edge. The Galaxy A2 Core is tiny by today’s standards with a 5” screen with 540 x 960px resolution (that’s 16:9). The whole thing measures 141.7 x 71.0 x 9.1mm and weighs 142g. The battery capacity is 2,600mAh.

 The phone sports a 5MP camera on the back (1.12µm pixels, f/1.9 aperture) as well as an unspecified selfie camera. The Samsung Galaxy A2 Core will run Android 8.1 Oreo Go edition on an Exynos 7870 chipset with 1GB of RAM.

The dual SIM models will have a dedicated slot for the microSD card. On the connectivity side, there's microUSB, a 3.5mm audio jack (with FM radio support), Wi-Fi at 2.4GHz, Bluetooth 4.2. What’s missing is HD Voice and NFC. There will be an A-series event on April 10, but the Galaxy A2 Core is pretty low profile and may be unveiled quietly without much fuss.
