My phone no longer makes sounds when I get a new message (Messenger, Hangouts, Facebook, Messages), nor the LED blinks.
I tried reflashing my ROM, twice. (DN3 v5+ Full)
Both times with wipes.
EDIT: It makes a sound when I get an email in GMAIL.
I checked the settings but couldnt find LED anywhere.
When I dial *#0*#, LED doesnt even appear in the tests.
Sidenote: LED when booting up and charging, shows on.
