When connected to any earphones or car bluetooth, if I'm listening to music and I attend a call and disconnect it, bluetooth connection starts having problems. There will be gaps in sound output and suddenly voice becomes very high and then works fine if I disconnect the device and connect it again most of the times. Sometimes even after that it starts acting up and frustrated me will stop bluetooth completely for a few minutes 😑 Happening from the Beta update version 1, don't know if its there in ONEUI7 .
