I updated my Moto Z4 to QDFS30.130-42-1-2 tonight when prompted for a system update, prior to this I've had no issues with Bluetooth connectivity including earlier today. Following the update my Bluetooth head set cuts out while playing audio. I've verified that it's not related to the headphones (tried multiple pairs w/phone and verified those pairs work without issue on other devices), I've tried restarting my phone and resetting the Wi-Fi/moblie/Bluetooth with no improvement.
As an update, I went through Verizons troubleshooting for my phone, the issue appears to resolve with safe mode enabled, but no apps have recently been installed or updated aside from the system update. Using Simple System Monitor I can see CPU spikes that appear to often coincide with the disruption of the Bluetooth audio.
2nd update.
Appears safe mode only resolved issue because airplane mode turns on by default. Issue appears to be related to Wi-Fi being turned on while using Bluetooth (didn't check to turn on Wi-Fi when originally testing safe mode). Turning off Wi-Fi resolves issue regardless of mobile connection, when turning Wi-Fi back on issue immediately returns.

After my Moto z4 update, June 2nd, my Plantronics PLT-M70 bluetooth stopped having clean calls over WiFi. I have to turn WiFi off and revert to cell signal for clean calls without broken, unacceptable conversations.
I never have my WiFi on and only utilize cell data so that shouldn't be an issue in my case at least. And it's not a signal issue. My music will play fine until connected to a Bluetooth device then it skips like crazy. And when I use the power button to dim the screen then push it to turn the screen back on, audio completely stops for a good 1-2 seconds.
3rd update.
Turning off after some additional time/testing, turning off Wi-Fi does not fully resolve issue, just less frequent/noticeable. When attempting to re-pair my phone with my cars' built in Bluetooth system, it had trouble connecting and when it did connect you could see in the Bluetooth menu that it was frequently reconnecting.
Having the exact same issue. Plus my phone is getting super hot when doing anything. I can't find a way to fix these issues. It's ridiculous.
Hello, Xanakira. It's important that your phone functions properly, so we're here to help. Do you have trouble connecting to other devices? I'd like to investigate further. Please check your private messages for details.

This issue is affecting numerous customers and hopefully anything discovered via Private Messaging will be shared publicly.
From a previous post, 'Spoke with Verizon support. They say it's a manufacturer issue and are working with them to resolve it'. @tracyb_vzw can you follow up on that and get an update?
Xanakira,we're truly sorry to hear that you did not receive an update. You can rest assured that we're currently working with Motorola to find a solution to this Bluetooth audio issue.
Meanwhile, we have identified a few workarounds to resolve this behavior. If you have a 2.4 GHz and 5 GHz frequency capable Wi-Fi router, please connect to the 5 GHz frequency. Also, please make sure to turn off Bluetooth and WI-Fi scanning for location services on the device via Settings>>Location>>Wi-Fi and Bluetooth Scanning>>Off.
Please let us know if this yields any results on your end.

Same here, turning off wifi marginally improves the stuttering but does not come close to eliminating it. NOT A FIX.
Factory reset did not fix the problem either so don't waste your time. Not a fix either.
Thanks for biting that bullet, I was dreading having to get everything set up again on my phone to test that.
Spoke with Verizon support. They say it's a manufacturer issue and are working with them to resolve it. So it's nothing we can fix. They put me on a list for when they have a fix. I'll update when I have one.
We appreciate all the testing for the issue with the Bluetooth connection. We'll be looking into this further from a more software focus route. Please be sure to check for any new update or patches.

I am having the same Bluetooth issue with my Moto Z4 after the latest update. My phone is completely useless now regarding any Bluetooth connectivity... music, phone calls, etc. I'm ready to trade it in for something else. I have tried all of the suggestions, but the phone is still skipping continuously. I'm so frustrated that I want to trade this phone in on something else. If a patch is ever released, I'm sure that it will be months before it happens.
That definitely seems like a major connectivity issue, eolsonwatson. The device shouldn't confuse the Bluetooth signal with Wifi and cellular signal, but that is what it sounds like. Beyond resetting network settings, I would recommend resetting the device settings. This should not cause any loss of content like photos or contacts.

From the troubleshooter
"Restoring your device to default settings helps when the device crashes and resets itself or when apps freeze/hang or reset the device.
There is no option to reset only settings on this device. However, network settings can be reset. To remove all data and settings, perform a Factory Data Reset."
Here is a post from a different forum -
Talked to Motorola. They are definitely aware of this problem and are working on it as we speak. New update will be released when fixed. They gave me temp fix which seems to be working. Go into locations and turn off Bluetooth and Wifi scanning. Just means that has to be done manually for the time being, but definitely worth it to have Bluetooth back.

Well, it sounded promising. I disabled Location->Bluetooth and WiFi scanning and it had NO effect on the broken/distorted bluetooth audio when making a phone call over WiFi. I restarted my moto z4 phone to see if that was needed, with no help. I 'forgot' my PLT-M70 bluetooth device and re-paired with no positive result. Still broken/distorted bluetooth audio. Not sure if there is another trigger to make that solution work for me.
