For about 2-3 months ago, my M3S's screen started to have vertical-red lines and horizontally bluish colour deformations. The phone was kept in average conditions. The current system version is: 220.127.116.11. The flickering comes up whenever I start to search in Youtube and watch videos, also it stays for a long period.
Is it by the system or by the hardware?
I hope someone can help me.
