I have the XCover 3 bought because I have to handle a lot of the open air to the device.
First the positive: it makes a robust impression, the handling is OK. It runs smoothly when it is not overloaded with apps. The images and movies are sufficient. The integrated memory is available with 5GB, but expandable with an SD card.
Negatives: and therefore only 3 stars. I lots of telephone calls with the phone on construction sites it happens from support and to which the display is moist. This can not be used in the moist state. I do not know what Samsung intended thereby produce a display for an outdoor mobile phone which does not function in the wet state. So who needs to use the phone outside, should always have a cloth case.
When dry, the device is working properly. Display legible and bright and it is just big enough to let it disappear in your pocket.
