Come to think of it, it isn't just the facebook app. Using the FB app as an example, every day i am asked about my location settings etc. I just hit ok or close or whatever the button is. Just found a photo on my phone i took... "Location Accuracy Turning on Wi Fi will improve location accuracy. Ok / Settings". I click ok & all is good ... until the next day. Never used to happen before i upgraded to iOs7 (was on iOS5). How do i stop this? It's irritating.
