No sound for incoming messages

[Erika4]

Quand on m'appelle ça fonctionne mais quand c'est un message ou une notification ça ne sonne pas

When someone calls me it works but when it's a message or a notification it does not ring - GT

Hi @Erika4, let me see if I can help out here. 

I have translated your question to English as this is an International forum, please post any replies in English and it will be easier for me and other users to assist you.

It sounds a bit like the messages app is set to make no sound for incoming messages. To change this, find and tap Settings > Apps & notifications > Show all XX apps > Messages > Notifications > Other notifications > Behaviour > Set the behaviour to either "Make sound and pop up on screen" or "Make sound".

Try this and let me know how it goes!
