I just want to make calls!

In our family, there are many mobile phones. From I-pod to the Samsung C270. The functions of these phones can, partly out of ignorance, not be used in full.
I prefer to just make calls. For the Samsung C270 is the right place. The folding mechanism protects the small mobile phone, resulting in the unfolded state well usable keys and serve as inputs or off for calls. The battery lasts loose a week usually in standby.
Whenever there is a repair has required the service department denied this, as it should allegedly be a moisture damage.
This practice is to get over considering the low price.
