Recently, I had a problem - Jabra bluetooth stopped connecting. Although before that half a year it worked fine. Tech support dumps everything on my phone, they say, the firmware could fly. At the same time, the bluetooth did not want to communicate even with other phones. In general, having searched the English-speaking forums, I found a solution to the problem. True, it looks more like dancing with a tambourine, but the main thing is that it works. So.
Instructions for connecting Jabra to the phone
Wipe the bluetooth “JABRA” device from the phone.
Turn off the phone, remove the battery.
Connect the headset to the network charging, turn on the charging to the network for 10 seconds (soft reset).
Disable charging.
Press the pairing button on the headset, the blue LED should light up (and light up continuously).
Put off the headset and start the process of connecting the headset on the phone (search for devices, pairing, etc.)
