X4 Project Fi version - Bluetooth randomly creates loud jarring static noise

2018-01-02, 23:08 PM

Hi,

 

I purchased the X4 through google using Project Fi service.

When I'm using my bluetooth headphones or bluetooth through my car stereo, I will randomly get a sudden loud hiss/static sound that will last for about 1 second.

i'm currently on 7.1.1 android with the November 1 2017 security patch level.

Has anyone else experienced this with this type of phone and is there a fix for it, or has Lenovo acknowledged it as a known issue?

 

Thank you

Hi wookietv

 

This is the first time we have heard of this so it's definitely not a known issue but thanks for sharing it here with us. I would just like to ask when did this issue start? Have you tried connecting it to different Bluetooth devices to see if the issue persists? Have you tried booting it to safe mode to see if it will be the same? 

 

Would you also update your profile with the serial/IMEI/MEID number of your phone? This will help us investigate. Make sure that your Motorola Privacy is enabled. Please check the link and update your profile here.

 

Regards,
Ella

Hi,

The problem has been going on for about a month or so, just getting around to finally researching it.

I have tried it on two devices, my bluetooth headphones and through the bluetooth in my car stereo and it occurs in both devices.

Sometimes it's more often and will happen every few minutes and then sometimes it will go a few days where it doesn't happen. I can try booting in safe mode and test it then, but it may not happen for a few days.

Thank you

No worries,  we will help check on it. I may need to ask for the make/model of the Bluetooth accessory or the vehicle. Can you also send us the bug report and let me send it over to our Bluetooth Engineers: 

  1. Go to Settings -> About Phone -> Tap on Build number 7 times on the build number to go into the developer options mode]
  2. After the above steps, Developer options will be enabled.
  3. Go to Settings ->Developer options -> Enable USB debugging > Toggle On
  4. Enable Settings -> Developer options -> Enable Bug Report shortcut > Toggle On
  5. Enable Settings -> Developer options -> Enable Enable Bluetooth HCI snoop log > Toggle On
  6. Once the issue is reproduced, Go to Settings -> Developer options -> Click on take bug report or Press Power button and then choose Bug Report from the Power down menu.
  7. Wait for some time until the bug report is collected. It takes around 3 to 4 minutes to collect the Bug Report.
  8. Then upload the BugReport to your personal Google Drive and then share the link to the BugReport on the forums in a reply or via a private message.
  9. Provide observations of what you saw happen right before the bug report was taken. Please indicate the time that you observed the behaviour in local time.

Thanks!

Thank you, I've made all of the settings as you requested.

One thing to note, since my last reply, the phone has now updated to 8.0 Oreo, version OPW27.1

 

The devices I am using are Jabra Move OTE21 headphones and the Nissan Versa Note stock audio system.

 

If it happens again, I'll get the bug report and reply back here.

 

Thank you

Hi wookietv

 

Sorry for the delay. It seems that this issue is caused by a very noisy environment with a lot of cross-interference. You would need some better logs to be able to pinpoint a method to avoid the interference. This is not a device issue.
