Stupid phone!

I have never had an Ericsson phone before and this will be the first and last one I have. Has anyone else had problems with Ericsson K800i? Or is it just my phone?

First time some characters and ALL numbers disappeared from the monitor. I send it to repair and I got it back not even a month ago. On Saturday I had to turn it off and after that it was impossible to turn it on again. The monitor shifted between black and white.

So if I don't answer or return your calls it will probably be because of this stupid phone.
