Android phones use varying Bluetooth protocols. With some phones, you have to clear your "Bluetooth memory" before connecting to your BAGTAG. Doing this generally involves the following steps: go to Settings > Apps, reveal System Apps, and search for Bluetooth share (this can be named differently depending on model and brand). Tap storage in the Bluetooth share information, select the 'clear data' option and reboot your phone. Please note that this will disconnect your phone from other devices. If following the above steps did not work, please contact us through the contact button above.
