When you are going to buy a smartphone just dont only look at its specs sheet.Try to buy an android or iphone.Xiaomi redmi note 4 is one of the best mid range phone in india and surely oneplus 5 is the beast of smartphones.Sony handsets are overly priced and asus smartphones doesnt have enough battery capacity.
Just keep in mind that not only buy smartphones seeing their specifications, just see the user reviews and their after sale services before buying an smartphone.
