If you installed the chinese firmware on your meizu 16th, you probably noticed a low volume and distorted audio in general when using bluetooth.
Even when enabling the standard equalizer the problem persist. Audio remains low, bass and trebles are not reproduced well.
So, here's how I managed to fix it and bring it to the best quality:
Even when enabling the standard equalizer the problem persist. Audio remains low, bass and trebles are not reproduced well.
So, here's how I managed to fix it and bring it to the best quality:
- Download an mp3, connect your bluetooth headset(I used my airpods) and check the quality
- Root your meizu if you haven't done yet, following this tutorial: Root Guide Link.
- Install from playstore Busybox Busybox Playstore Link, open the app, click install, don't reboot yet.
- Download this zip: Bluetooth Libs Download, extract and place them in a folder in your internal storage
- Using a Root explorer(I use XPlore: XPlore Playstore Link) copy and replace those libs in system/lib and system/lib64 folder.
- Open the file /vendor/build.prop and edit this parameter: persist.vendor.bt.a2dp_offload_cap and add -aac at the end. In this way you will change it to: persist.vendor.bt.a2dp_offload_cap=sbc-aptx-aptxtws-aptxhd-aac. Save the changes.
- Go to the path /vendor/etc and rename the file audio_effects.conf to audio_effects.conf.bak
- Reboot now. This is very important.
- Install ViperFX from this link ViperFX_2.5.0.5 and execute it. It will ask to install drivers, click yes and wait, it will freeze for a while, just wait. when it's done, press ok.
- Reboot again.
- Now you can open ViperFX, enable it and test the sound quality(volume should be louder and better quality)
