Yes, when I receive a text message, nothing happens, no notification by sound, no vibration, even though both are switched on, the melody is chosen (I tried to choose others, nothing happens), notification by vibration is on as well. No result though.

The phone is Sony Xperia Z2, Android version 4.4.2. Vibration and sound tested and function well in all other apps and situations.

Must be peculiar to the phone, because I don't have the problem on a Note 3 running 4.4.2. Make sure that sounds aren't only enabled in the phone's settings but in the SMS app's settings as well.
