2. Tap Applications > Manage Applications (this will be labeled as Application Manager on some newer versions of the Android OS) > Grindr > Force Stop > Clear Cache
Then check your current location.

2. Tap Location
3. Uncheck and re-check the on/off option making sure to leave it 'on'

Be sure to also check your data connection. When you're using a Wi-Fi network, location is determined by the network's IP address. Disable the Wi-Fi settings on your device and try using Grindr with only a mobile (4G, EDGE) network connection.
