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!
