The pop-up that says "Uber has been using your location in the background recently"? I don't think this is true. I think the pop-up is telling me it was using my GPS, especially since the GPS icon on the Settings page where you can retract the permissions was lit up to indicate "Recently used". I don't want to jump to conspiracy theories but the experience scared me a bit because it was around the exact same time of day I had grabbed an Uber to go to work the last time I had used it. Perhaps it was an errant random notification meant to scare me, perhaps it was a late delivered push notification opening Uber in the background, perhaps it was Uber seeing if I was home and wanted to commute to work again.
