Got my JB 7+ 256GB last week. I originally ordered the Spigen air cushion case on Amazon with a clear back. I was concerned about getting debris under the case and scratching the phone, so I ordered a glossy skin to go on the back from best skins ever. It was easy to apply, but once I put the case on, it started sticking to the glossy skin on the back. I ordered the matte skin from best skins ever last week and it came in Saturday. I took the glossy one off and put the matte skin on the back of the phone and now the clear part of the case doesn't stick to it. The matte and glossy are totally different textures.
