Hello to all! Yesterday I saw that dots or bubbles covered the right corner of my navi display. Is it issue from the firmware, or the display will failure? 
BTW: The display working properly for now!
Thanks in advance for the information! 

Looks like water marks to me.  Has it got wet?  Am I right in thinking its one you got and fitted yourself?  I'd be contacting the seller.

No, I haven’t moistened.

Looks like surface marks to me rather than the actual display. Use a very clean micro fibre cloth, with just a smidge of autoglym fast glass (spray it onto the cloth NOT the screen)

Use only light pressure as you wipe the screen. 

 

You may have sneezed at some point.

If you mean phlegm, No it is not! In that surface the white inscriptions looks like the colour of it is orange ?

Do someone have an idea what the problem is ?

As a non Freedom member only has 1 hour IIRC to edit their posts then I'd edited it accordingly.
