After the first falling on the back surface formed severe scratches. Self healing in this case turned out to be almost useless – as shown by reference check after 2.5 hours, disappeared only minor scratches, and large remained in place (and it is highly unlikely that they will disappear in a few days).
Curved display helped smartphone firmly survive falling on end, and on the screen. Despite the fact that the screen itself is flexible (with plastic backing), it provides protection for the glass, and that did not survive the next two downs. Despite the fact that the central part is not affected after falls, upper and lower edges were covered with mesh cracks. In this case, the curvature reduced contact area and increased the chance of breakage at the edges.
However, to honor LG, smartphone continued to work even after a nasty fall. However, it is unlikely that anyone would use the device after such damage, as there is a serious chance of broken glass scratched.
