Its a message about performing audio wizard bug by your self.
1. First connect your earphone with device.(make sure it has high quality bass)(and i dont know with Bluetooth operated, because i dont have one).
2. Than open audio wizard.
This is my headphone profile. I didn't set any listening profile.
3. Than open custom preset.
Make sure that it set to normal as shown in screenshot.
4. Now increase first 3 and last 3 frequency column to 10(full) (31hz, 62hz, 125hz, 4khz, 8khz, 16khz to full).
And save this custom preset.
5. Now what you have to do is play some music.(it should be playable in background).
6. Increase bass to 20.
And listen music in 20 level bass.
U will clearly listen difference between 0 bass level and 20 bass level.
Save this.
7. Now listen that music in normal preset.
So, now you have 3 Equalizer set.
1. In normal.
2. In custom when bass level is 0.
3. In custom whan bass level is 20.
Make sure that u are able to clearly listen difference between all 3 of them.
>>>Now lets begin with bug.<<<
1. Set custom with 20 level Bass. And save it.
2. Play music.
3. Remove audio wizard from recent.
4. open full notification panel.
5. Try to do this 10 time, you should feel change in Equalizer. While doing this. If doesn't than lock ur device and unlock it, again do that for 10 times or more until u feel the difference. As shown in video.
6. If you feel any difference (that time you had actually set 20 level bass, but you will start to listen 0 level bass when you feel the difference)(means you feel that bass has reduced). than open audio wizard and open custom preset, now you will listen that bass has increased.(make sure that you open custom preset, means you are inside the custom preset).
7. Now again remove audio wizard from recent.
8. Again do that notification panel thing.
9. As you feel difference, open audio wizard.
10. Set it to normal. You will again feel change it audio.
It proves that only bass reduced while doing notification panel thing.
