I just got a new Galaxy Tab s5e and the Verizon Folio case for it. I accidentally put it in the case before installing the SIM card and now I can't get it out of the case. The instructions say once you get two corners off the tablet will slide right out which seems obvious but I can't get two corners off! I can get one off but the others feel like they're cemented on. I've applied quite a bit of force and I'm actually afraid I'm going to damage the tablet before it comes out of this case. So how do I get it out?
