Running on Android 8.1 Oreo, the device pairs 2GB of RAM with a 3000 mAh battery to balance everyday performance and endurance. Measuring 71.9 x 153 x 8.3 mm and weighing 144 grams, the K40 2019 maintains a slim and lightweight profile, while its single SIM configuration keeps connectivity straightforward.
