One plus is the new brand in Indian market they make very good phines in very affordable price but after sale their product they will make you fool. I have one plus 3t and phone falls down from my hand when I contact to coustmer care they tell me that screen price of the phone is 12000 and body of the phone is 6000. I get shocked that how they can take 20000 when the price of the phone is 29999. Delivery time product is good it take 7 days to deliver their product but when you give them phone for servicing they will take 1 month to send the product. App and website is good interface is average.
You can trust on phone but do not trust on oneplus. In service centres. They only make you fool.
