    Verdict

    The LG K40S (2GB RAM + 32GB storage variant) is an entry-level smartphone featuring a 6.1-inch HD+ FullVision display, powered by an unspecified octa-core processor (often listed as 2.0 GHz) and runs Android 9.0 Pie (upgradable to Android 10). A key advantage is its dual rear camera setup, comprising a 13MP main sensor and a 5MP Super Wide Angle lens for versatile shots, along with a decent 13MP front camera. It includes a 3,500mAh battery, DTS:X 3D Surround Sound support, and a dedicated Google Assistant button. On the downside, typical cons include limited internal storage (quickly consumed by the OS and apps), basic display resolution, modest performance due to only 2GB of RAM, and the use of a micro-USB charging port instead of the more modern USB-C.
