Hello about 5 months ago I bough a mi4c was really happy with it, now 2 days ago a discovered a yellow tint on my display. So I contacted ******* about this issue, and ask maybe for a screen replacement. I got a response that the warranty doesnt cover the occurrence yellow tint on the display. "The last feedback was We know the screen is covered in hardware,but yellow spots is from lots of reasons,for example the external pressure and high temperature and soon on,in generally,it is not possible to appear the yellow spots if you use it normal." I would like to ask for some tips, still I will not invest buying a new LCD panel for a phone is is 5 months old and is under 1 year warranty.
