My 2 Moto Z4 (wife has one too) updated to QDFS30.130-42-1-2 Android 10. Prior to this I've had no issues with Bluetooth connectivity. After the update my Bluetooth started to shutter / skip. I've verified that it's not related to the speekers/headphones with different phones and computer. This looks like it is the Motor Z4 and the update. Other online information says Motorola knows about the issue. There are some recommendations for a workaround... This includes turning off GPS location, turning off WiFi and Bluetooth scanning and turning off WiFi. I found that doing all of this does make Bluetooth not shutter. But,. Why would anyone want to turn off WiFi?? Think Verizon wants more $$ for us using more cell data... Hopefully, sometime, there will be an update to the update. But doubt Verizon will ever do that. Be surprised.
