This might be a bit confusing because the new iPad mini looks a lot like its predecessor. At a glance it looks identical even, but according to the specs, the new iPad mini is actually taller and also thicker compared to the iPad mini 3. This means that existing iPad mini 3 cases will not fit the tablet.
But what about the iPad mini 4? The dimensions are identical, but even then there might be some compromises you’ll have to make depending on the case you’re using. This is because the new iPad mini has longer volume rockers, meaning that if the case you’re using has made-to-fit volume rockers then this could pose a problem. Apple has also opted to reposition the microphone where it is placed towards the middle top portion of the tablet, versus next to the camera.
This could result in the microphone being muffled if you’re trying to record. These are some of the things you have to consider if you plan on reusing any old cases.
