I have a S40pro over 1 month.
Problem: no sound (not in speaker, not in earphone).
Further information:
I don't use it as a phone, I only use it for navigation and for internet by WLAN.
Navigation: Magic Earth or OsmAnd when driving a car (voice is very important),
OsmAnd for outdoor (without voice).
I can use both offline.
Videos by WLAN (e.g. YouTube) have no voice, are deadly silent.
What I did: I activated all sound options, but this did not help.
What I did: I uninstalled some newer apps, but this did not help.
From Google Play I installed "Phone Doctor Plus", this tool shows a red "X" what means that the speakers cannot be tested.
What must I do?
Thx in advance for your hints,
Josef
