Last but not least, if you want a top gaming smartphone costing no more than Rs. 50K, you may want to take Samsung Galaxy Note 5 into consideration. It boasts a 5.7-inch Quad HD Super AMOLED screen, Android 5.1.1 Lollipop (upgradable to Android 6.0.1 Marshmallow), an Exynos 7420 chip set, 32/64/128GB of non-expandable ROM, 4GB of RAM, and a 3,000mAh battery. Therefore, its gaming performance is very good. You definitely can play Mortal Kombat X, Dead Trigger 2 and N.O.V.A 3 with no problem.
