[How To] Root Samsung Galaxy A70s & Unlock Bootloader

The latest entrant to the Galaxy A Series of smartphones is the Samsung Galaxy A70s that was released in September, 2019. Featuring a  6.7 inches Super AMOLED capacitance touch screen and a resolution of 1080 x 2400 pixels, the smartphone runs on Android Pie 9.0 deriving a beast of a power from Octa-Core Qualcomm Snapdragon 675 processor. The Galaxy A70s comes in two variants; 128 GB – 6 GB RAM & 128 GB – 8 GB RAM with a dedicated micro-SD card slot expandable up to 1 TB. We guess 1 TB will be more than enough for storing all your photos, music, and videos.
