I bought a gel case from Amazon for my iPhone6. But after i put the case, on the back side i can see the oil rings (kind of bubbles). Anyone have an idea how to avoid those?
Could you provide some pictures of your case with the bubbles. Maybe take a pic in front of a mirror. I have a gel tpu case which is transparent too. But I have no oil rings. There are a lot of really tiny dots on the case, so that the case does not stuck together with the phone.
