A day after Christmas I bought an iPad mini 2 I turned it on I found that there was a black speck of something under the glass I returned it (I bought it from Walmart and had a 15 day return policy.) I exchanged it and got a new one, the second one had the worst battery ever it wouldn't stay on for more the 4 hours and the other lasted at least ten hours. So..... I exchanged another got the third opened it up had a nice big scratch,UNDER THE SCREEN. Returned it got another had a distorted speaker that sounded fuzzy, I exchanged it got another,I have been using it for a few days now and I am seeing that the left side of the screen is yellowish I heard about this problem but is it just me looking for things wrong with it now, is it really worth it to return and get an even worse problem. Please help I need suggestions.
