Hello, I just purchased an iPad mini 4 wifi+cellular 128GB and I am puzzled to see the screen has a yellowish tint compared to my iPhone 6s plus, my iMac, my wife's macbook pro and her iPad mini 2. I am comparing the same apps or same photos, etc. Should I go back to apple or it's normal on this model? Also, I actually had the iPad mini 4 wifi only for the last few days and exchanged it to the wifi+cellular model and it didn't seem to have that yellowish screen problem.. Anyone? Thank you Edit: I am wondering if it could be just a brightness issue were it doesn't go as bright as the other apple product I own and being a bit ''darker'' creates this slight yellowish tint?
