  1. I am extremely disappointed with my HTC! FIRST – it fails to sync using Bluetooth with my hearing aid app (the app works fine paired with other phones). Now I find it doesn’t sync with a new Smartwatch (which also works with other phones.) I’ve spent literally hours in HTC “Help” chat. The little helpers seem keen to help but will not admit that their product is RENOWNED for sync problems. They do their best – or rather – did! Now They do not even respond!
    In other words – HTC has a VERY MAJOR problem, refuses to acknowledge that fact, and closes its ears to its frustrated customers.
    You have been warned!

  2. My issue with Bluetooth was that my HTC phone and my bluetooth capable uniden landline handset were no longer able to connect. After trying the steps listed in your blog, up to and including step 6, the only thing that worked was to unpair my phone from the Uniden handset (via the Uniden bluetooth menu) and suddenly they could “see” each other again. As I turn off bluetooth when not at home or in my car, to prevent my phone battery draining too quickly, I think the issue mentioned by Nishad is occurring and will try using the “flightmode on/off before turning HTC bluetooth back on” idea to see if this helps.

  3. After trying different suggestions I have figured out the real cause at least with my phone. ( i hope these info helpful to other models also)

    My phone htc-x9 has an issue with bluetooth car kit with phone audio but phone contacts was working without any issue.

    My findings

    Clearing Bluetooth cache worked only once but again the same issue after you switch on & off bluetooth on phone. I have found that there is no relation with this issue & cache files.
    when you clear cache files actually what happening is your bluetooth device resetting physically that really worked (that’s what I understand with my limited knowledge). noramally this is not happening when you enable and disable bluetooth switch on phone.

    easiest way instead of clearing cache is…just enable & disable “flight mode” on your phone then turn the Bluetooth ON that will do the same effect and your Bluetooth will start working.

    To avoid Bluetooth issue again:
    actually Bluetooth issue starts when you switch off Bluetooth on your phone your Bluetooth device can be switched off/on any number of times. if your phone Bluetooth is ON always you won’t have any problem. incase if it is switched off just enable “flight mode” and disable it then turn the Bluetooth ON.

  4. holding down the volume down button then power button until the vibratesonly turns on cell phone .red and blue lines donot appera at all .it just restarts phone .

  5. I don’t see “Advanced Options” after Bluetooth is selected from Settings. I see “Scan”, “Rename this Device”, and Show received files. No “Advanced Options”.
