Mine is the same only on the right side of my switch.... oh well ... only good thing about this is I can tell my switch from my son's switch just by looking at it. I did his switch second, and I did a perfect job with his.
i had 2 big on in the middle of the screen and tried pushing them together in the middle and then down towars the charging port and left it alone and it went away. the heat from the charging made it go away
This only happens if you fucked up the screen protector application.
Bought one from eb games for $15 and yes I did stuff it up big time note to self once dust gets stuck behind on sticky side don't wipe it off that'll make it worst.
Plus if your going to apply it you need to do it correctly on the first go meaning putting it on to find out it isn't straight so you end up peeling it off to realignment it to find out now it has lots of air bubbles that won't stick down on screen lol.
