Dear team
I was purchase note 5 pro (6-64) via mi store on 4-4-2019. Problem in the phone lines show in screen. Same problem discussed with mi service center jabalpur, but executive are send back me, he asked your phone is liquid damage so warranty is not covered. My best knowledge my phone is not contact in water or any liquid. Please help me for this problem.
