UBER App can’t find my location?
Your phone’s GPS may not always be able to pinpoint your exact location. If you’re indoors, your phone may have trouble establishing a good connection to the satellite(s) responsible for letting it find your location.
The pin displayed in your Uber app tells your driver where to pick you up. By moving the map on the Uber app you can recenter the pin so that it accurately reflects your location. On the latest version of the app, you can also click ‘Pickup Location’ and manually enter and search for your address.
Refer to this article from Uber Support.
NOTE: Sometimes the actual tagging of the map is incorrect making search results unreliable at times. We recommend you add your frequent pick up points in your profile under “Home” or “Work”. Sometimes we also just tag the nearest landmark in our destination and wait for the Uber ride there.
