Answer 1

Recently, I was facing the same issue for Vivo and MI phones. I have tried everything described in this thread. I tried connecting as MTP, PTP; But nothing worked.

After many retries I found a solution for my case and may be it can help others too.

1. Open terminal window in Android Studio
2. Kill ADB server using following command: adb kill-server
3. Restart ADB server using following command: adb start-server

It solved my issue.
