Sound quality decreases when the screen turnes off
It happens because your phone turns on special settings when the screen goes off. There are two reasons for that:
- your PSP or WiFi cards;
- SPU settings decrease its speed after the screen goes off.
To solve this problem, change the screen settings:
- First, switch to «Expert» mode on a page of common settings;
- Then, activate «Don't shut off the screen» option in the «Interface» section.
