I have searched the net about my bug and found nothing so decided to post it here.
i have stock rooted 20D rom on my D802 phone.
LTE wasnt working, so i decided to fix it.
i switched the LTEconfigs.apk, and have to fix the line "ro.telephony.default_network" from 9 to 11 for the LTE option to show.
LTE works fine, but something else came up:
Now i dont have lock/unlock sounds, not touch and keypad sounds.
i did it couple of times just to make sure it really is the trigger and it is the build.prop change i did.
what should i do?
