I'm satisfied with oneplus 6t. Kindly take your device back and refund my money. My money is wasted here. Lots of issues with the mobile. I got cheated here. I need a proper solution. I paid 42000 for this device i need a proper solution for that i'll not let it go as it.. Money is very hard earned but you people fooling us in the name of smartphone. Take your mobile back and refund my money. Problem will be solved.
