In the video below, I run through a secret technique that usually resolves issues you maybe having to pair the DJI OSMO Mobile 2 with your android phones. Sometimes the app is not able to connect to the OSMO Mobile 2. Usually it's because the USB developer options are disabled on your phone. If this doesn't work, you should try moving the OSMO Mobile 2 to a field where there is no other bluetooth devices and try to connect your phone to it - sometimes rogue bluetooth devices tries to pair with the OSMO Mobile 2 and this basically stops your phone from bluetooth connecting to the OSMO Mobile 2. Hope this helps - check out the video below!
