i just bought an iPad mini 4 last night, and the screen seems very dim to me, but the only thing I have to reference it against is my iPhone 5c. Can anyone give me any insight? Is this how they are?
I use my mini 4 at about 60% brightness and it is plenty bright enough. The devices vary and if you have to use 100%, it may or may not be defective, but I think you should return it.
We just took delivery of 35 of this same model at work last week. 7 of them were very dim. It's a defect Apples aware of. Don't worry just return yours Apples very good about replacing defective units. It's mass produced, they can't all be fine.
