Read entirely before proceeding! I called ZTE directly. I told them of problem. Screen shot your home screens before you do this! They had me go into settings. Apps. Stock Android. Clear Data. I told them that will rearrange and put home screen to factory settings. She said no it won't. I screenshot all home screens BEFORE. Thank heavens. It did rearrange. I added 2 pictures. The one was before clear Data and the one after. She said stock Android is probably caused by 3rd party app. Even from play store. I don't know. Right now it's not popping up. I rebooted. Let's see what the days bring. I'm also having visual voicemail not working issue.
