| The stereo sound effect isn't working when my phone is playing music in landscape mode and is locked |
Problem:
The stereo sound effect produced in landscape mode disappears when the phone is locked.
Cause:
When your phone is locked, the system automatically switches to portrait mode, where the left and right audio channels are mixed for best results. Therefore, you will not get stereo sound effects.
