About the features of this device has been much written. My personal experience with the B2100, that I have been in operation for six months, are not only positive. Yes, it is the certification according to waterproof. One can take in the shower, without forming visible moisture in the device. Falls make the B2100 from nothing. Although the display glass is resistant to scratches, but the battery cover is me has never fallen out, let alone that the unit would shut down. Only the side rubber cushion shown after a few months on a little game. However, this is not the resistance of the device in question, because the housing of the B2100 is made of one piece. Columns can be found around only by the battery cover. Despite all the positive characteristics, have pointed to the other reviewers, my B2100 is now for the second time at the Samsung Service. The first reason for return concerned the notorious speaker problem interlocutors complained often, only dimly and quietly listening to me at times. Thanks to a new motherboard (and thus a new housing) and the latest firmware could this deficiency be remedied. After a few days, however, showed that the battery indicator did not reflect the actual charge. After the phone had switched off with an empty battery, the screen showed after only ten minutes of charging time already back to a full charge.
Samsung is doing here well to improve quality. Such a large proportion of problem devices within a product line is annoying for consumers and continuing its product loyalty in jeopardy.
