My LG G4 tabker constantly pops up a white dialog with just MIP :67. This tablet was at first on the Sprint network. I dropped the Sprint subscription on the tablet and just use wifi. If I turn the wifi off (and sometimes even with wifi on) i get that dialog with MIP : 67 every few seconds. I think its looki2nf for the LTE network, but thats not going to be there. Does anyone kmow how to turn this message off?
