iPad iPad 4 bluetooth issues, anyone?

Anyone else get frequent drop out with their bluetooth connections on their iPad4's? I'll be in the middle of using my keyboard, and it will just disconnect, multiple resets, restores and still the issue exists. I've tried 3 different keyboards as well, all fully charged and worked fine with our Mini, so it has to be my iPad....anyone else have this issue and fix before I take it to the apple store?

Thanks in advance
