Hi @Gerry5, let me see if I can help out here!
Your post has been translated 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.
The behaviour you are describing with the screen turning green when you watch videos, does this occur in all apps or does it only happen in a specific app?
As for the "voice message", If it is a voice mail you are referring to, I would suggest that you get in contact with your service provider. This due to the fact that there is no Xperia answering machine in the settings.
