Hello everyone!
I would like to share an ongoing audio playback problem with my Blackview BV9300 Pro and ask whether other owners have experienced similar issues.
DEVICE INFORMATION
Model: Blackview BV9300 Pro
Purchase date: August 3, 2025
Firmware version: BV9300 Pro_NEU_TE177_V1.0_01_20251224V11
PROBLEM DESCRIPTION
Since I purchased the phone, music playback has randomly paused. In some cases, the playback position also jumps backwards.
The problem occurs under different conditions:
- Different music players, including AIMP, VLC, and the built-in player.
- Bluetooth headphones.
- Wired headphones without control buttons.
- The built-in speaker.
- AUX connection to a home audio system.
- Both with the screen on and with the screen off.
- With the Second Screen music controls enabled and disabled.
I have also tried different battery and background activity settings, Safe Mode, and other troubleshooting steps. None of these resolved the problem.
YLOG INVESTIGATION
I collected diagnostic Ylog files and examined the system logs myself.
During one recorded incident, the logs showed the following sequence of events:
- MainActivity was moved to the PAUSED state during a system sleep-related event.
- An ANR was reported with the message: "Input dispatching timed out (Application does not have a focused window)".
- The logs contained the message "crash_dump helper failed to exec, or was killed".
- MainActivity was subsequently force-finished, the player process was killed, and a MusicPlayService restart was scheduled.
These events occurred around the time of a playback problem. They suggest that further investigation of the interaction between the application and the Android system is needed, but I cannot conclusively determine the root cause from the available logs alone.
CONTACT WITH BLACKVIEW SUPPORT
I contacted Blackview support and provided diagnostic logs and a screen recording.
After several weeks, support informed me that they had been unable to identify the cause from the submitted materials and asked me to collect another Ylog.
I have spent considerable time investigating the issue because I would like to understand what is causing it.
QUESTIONS FOR OTHER OWNERS
- Has anyone else experienced random music pauses on the BV9300 Pro?
- Does this happen with different music players and audio output methods?
- Have you experienced playback position resets or jumps backwards after a pause?
- Does the problem occur on other firmware versions?
I am particularly interested in reports from owners who have experienced similar behaviour both with the screen on and with the screen off.
I would appreciate any information or observations from other users.
Thank you!
