Please tell us some basic information before asking for help: Model Name: ASUS_X00TDE, Zenfone Max Pro M1 Firmware Version: PKQ1.WW_Phone-16.2017.2009.087-20200826 Rooted or not: Don't know Frequency of Occurrence: 2 days ago, everything went well. Normal volume to the bluetooth headset. All of the sudden, the volume drops perhaps only 10% even turned to max. APP Name & APP Version (If your issue relates to the app): Youtube, VLC, XPlayer, any APPS. In addition to information above, please also provide as much details as you can, e.g., using scenario, what troubleshooting you've already done, screenshot, etc. ======================================== Have isolated the problem with bluetooth only as a wired headset gets the normal volume. The bluetooth headset also works well with another non-ASUS phone. Soft reboot doesn't solve the problem. Seen similar posts but not quite applicable. Appreciate your help!
Hi Christine_ASUS, Please ignore my post at 9:59 p.m. I re-tested. Here are the answers: 1. Can the device work with other bluetooth headsets properly? Answer: The device volume is normal for my JBL BT headset, but not Airpods (which were used all along and reported with problem in my first post). 2. Does the issue remain the same after reconnected the bluetooth? Settings>Connected devices>Preferred device>Forget>Pair new device>Connect again Answer: Unfortunately, remains the same. 3. Please try to enter "Safe Mode". If the function works well in Safe Mode yet the issue remains out of Safe Mode, please check on any disturbance from the installed 3rd party apps. Does the remain the same in Safe Mode? Answer: Unfortunately, low volume in Safe Mode. I have a family member (my family is ASUS fan). Her (Zenfone 5 + Airpods) encounters exactly the same problem. Look forward to your further suggestion.
