Hello Friends, Dont do Following mistakes while buying Smartphone.
First decide the smartphone you want to buy according to your needs like Processor, RAM, GPU, Battery, Camera, Sensors, Schreen resulations and your Customization neads i.e. UI ( User Interface) .
There are two way to buy that mobile phone
1) Purchase on Online Store.
2) Purchase by Retailers.
But while purchasing by retailers use your proper mind. They try to sell you such phones who gives more commison on them like O* , V* and more. Such brands gives 14 to 15 % commision on purchasing such phones. So try to avoid it and purchase such phone which is value for money.
If you dont have proper sense to use phones then make insurence of your phone while buying it.
If you have less money then dont buy such phone lying in between 3000 rs add 2000 rs more and purchase any midrange phone sudgested my grate persons like Technical Guruji Mr. Gaurav Chaudhary.
While paying via Cards on swip machine try to pay via RuPay Debit or Credit card for less transaction fees. And try to hiden your password while typing in swipe machine from people who can try to see your processes.And never ever share your mobile boxs back side with any one because they can missuse it by using your IMEI number.
