No I didn't have it in a case. I bought one once but only had it on a few hours as it felt far too bulky. Maybe that didn't help but I've never had a case on a phone, besides the G3 Flip cover which added no bulk with it replacing the rear cover.Hell, do you use it naked? I mean without any case? Have not happen to me and I do have a rude use with it. Hope warranty makes it for you, cheers.
