I have a Galaxy s5 and I recently used an app I've used several times before. I like to keep my location settings on Power Saving mode to help save battery life. The app uses location settings so the typical message came up that says something like "the app needs to access location settings, would you like to change location settings?" I accidentally pressed "do not ask again" and did High Accuracy mode. Since then, I'm unable to slide my location to "Off" and unable to select Power Saving mode since it's grayed out. I've done a reset of my settings and tried clearing the cache on my settings as well. I even uninstalled the app even though I know it wasn't the app because I've used it before without this issue, but I was worried since the location has been on non-stop since. I can't turn it off for anything now. Please help. Thank you.
