Recently just to use my Jio sim I gone to buy phone within 10000/- price range. Two phone short listed one coolpad note 3 & other Vivo 51L Coolpad note 3 has 13 mp camera & other one has 8mp but on comparing found that Coolpad is selling items with wrong advertisement in actual its camera is worth only 5mp. I bought Vivo but my friend Coolpad now he is complaining sometimes about battery backup & sometimes speed issue. Inspite of Jio sim Coolpad is slower, they are claiming 3gb Ram but still . In vivo with 2gb ram I never have such problem.
At last I suggest dont go on advertisement blindly for online shopping, first visit showroom see the product in actual.
