Yea I had the same issue exept my phone had a lot of lines so it's best to go to the Samsung showroom in a mall and ask them to get it fixed they will do it for you and before going call the showroom and ask them if they have the material to fix it if not then thell tell you the date when it will be there
Kindly complaint to Samsung customer support through Samsung Members App as error report also send log files Along with this error report for this issue. Then go to service center for replace/repair it's. If you like please accept as a solution it's help to others users also, click on 3dots in my reply section and click on accept solution. Thanks.
