OK well after seeing your posts in other threads and seeing what problems you've had I've come to these conclusions:

It seems like you're:

1. Pressing "end call" during calls
2. Sliding the lock key when you hit "enter"
3. Talking into the charger unit instead of the microphone (the microphone is conveniently located at the bottom of the phone)
4. Putting the phone in a freezer
5. Putting your headphones into the charger socket. The headphone socket is the same shape as the end of your headphones. If you are using that socket, look inside to see if it's full of beans. If it is, please remove the beans.
6. Trolling

If you address these issues the problems should disappear.
