Problem with wlan & message ringtone

[MrPasseur]

Hi,

since I have connected my mobile to the PC, it started to react in a strange way. When I'm receiving a message, I hear the content of the message I received (what's more, it's in German). In addition, every 2 minutes the mobile switch on the wlan connection and after 10 seconds it turns off. What can I do to fix my mobile?

I would recommend that you repair the software in your phone via PC Companion:

If the problems still persist after the repair, please get back to me.
