A71 screen problem

[Jazielle]

My phone has suddenly appeared white vertical line in the middle with no reason at all. It happened 1 month after I updated its system to OS 12. Anyone here who experienced the same? What did you do to solve the problem? Thank you for those who could give me an answer.
