Hi All, I purchased an iPad Mini R yesterday as a gift for my girlfriend. Obviously this won't be opened until xmas and I have concerns after reading these forums. Now, she is not a techy and won't be that observant towards screen tinge pending its severity (To be fair, not even sure how much I'd notice it). So I have these questions: 1) Is it a common or rare issue? 2) How severe is it? 3) How likely is a non-geek to figuring this out? Her iPad is being shipped from China right now so it may be in a different batch than those that already received it and have found these issues. Thanks for reading!
