Verizon Carrier Device/Model Number - SCH-I545 Android 4.2.2 When i purchased my phone a few weeks ago and had no case and just the thin plast cover on the screen that comes from the store the air gesture's were all working fine. I do not remember seeing an icon however. Now for some reason they do not work at all. i am 100% sure they are turned on. i've restarted the phone many time. Also there is no icon at all at the top, should be a hand in a diamond shape. Is anyone having this issue? I have the phone in a Spigen - Neo Hybrid case on it now, with a screen protector. Phone has never been dropped. Just can't figure out why any hand gestures are not working. Any help and/or suggestions would be great. Thanks All, John G.
