when I choose non system notification sound in whatsapp and a message arrives the device only vibrates and doesn't sound the notification sound I chose. when I choose system sound it make the sound . please solve it for non rooted device .
doing something the wrong way for a long time doesnt make it right. if you always drive too fast for 10 years and never get caught you cant tell the police it never was a problem beforeBut, nevertheless, it was your ROMs that worked before updating 7.7.13 successfully on the locked bootloader. And I use your ROM from the very first version on Android 7. xD
This is how it worked:Did you install Magisk/SuperSU right after rom or booted MIUI and again in recover and install? Try other way also.
