Coool pad e Mega 3 sports a 5.5-inch IPS HD ( 1280 x 720pixel) display which is quite common for devices in this range.The device is driven by its custom user interface ( UI) on top of Android 6.0 Marshmellow and is powered by quad-coreMediaTek MT6737processor - a good combination for a phone at this price range. The device has 2GB RAM and 16GB on-board memory which can be extended up to 32GB.The phone runs smoothly unless you shuffle between multiple applications, especially during a game.With a 3, 050mAh battery, the Mega 3 can run up to 10-15 hours under moderate use which is fair considering the large screen size.The 8MP front camera takes good selfies even inlow light without using a flash. The8MP primary cameraworks fine in outdoor conditions, but in low-light conditions, the quality of photos is not great.
