If you have any very thin plastic cards in your wallet, that did the trick for me. (My insurance card, which in my case is about 1/2 as thick as a credit card). I slide it under one edge, then worked it underneath all the way across. Once I had created a gap that way, I wedged it into the gap and used it to push down.Be careful of where you hold it as well (not to press into the glass or the volume buttons too hard)
