Samsung U600 : user friendly or not?

Nowadays, with the advances in technology, incredible electronic devices are available in the market. Sometime, some people including me find it difficult to cope with those stuffs. A couple of days ago, I bought Samsung U600 from Car Phoneware house. It is stunning in look. Very thin and light. Black and Gold colour. 3.2 mega px camera phone with many advanced features. Moreover, it is not locked to any line, so working with any SIM cards.

My problem started on Day 1. It has 4 touch buttons in addition to normal press buttons. These are quite sensitive even though there are 3 levels of sensitivity you can choose. So whenever I opened this slide phone, part of my finger was on one touch button. As a result, recent call list came up. With a further subtle movement, my phone had already been ringing the last contact I made a call. It happened several times in my 48 hours use. When I tried to stop it, I had to unlock first by pressing the middle circular button. So just after 48 hours of use, you may check below. I broke it into pieces simply. I have no time to go back to shop to return or to exchange. Anyway, now I am in piece of mind. :)
