Screen scratch / 'rainbow' line [help]

[Larazord]

Hi everyone! I have the xperia m4 aqua and so far it's been a great phone, no complains with almost nothing... But I recently noticed something in my screen, when the screen is like white (like while I'm writing this), I see a little vertical "rainbow' colour line that seems to be a scratch, not a big deal but I wanna know if I should be worried, or if there's a fix or simply I should buy a case or something...

Well, that's all, humm... Thanks and sorry for my bad English lol

Hi,

That do sound like a scratch. In some cases a scratch can reflect white backgrounds into rainbow colors, perhaps a screen protector can make it less visible but I can't say for sure. I would say that a permanent fix for this would be to change the display which can be done by our authorized service center. You can contact your Local support for information about nearest service center and how to proceed.
