I am running updated Google photo apps and originally was syncing but on August 23 it stopped uploading pics. All settings are OK (plenty of space), but it doesn't recognize that the wifi is on to upload pics. When you try to manually it gives me the option to do it over the Cellular data which I don't want to do. Anyone else having that problem? Is this a phone issue? Another forum suggested a phone issue and to factory reset, but I wanted to see if others with a z had this problem. Thanks
