I recently upgraded my contract, and picked this phone for its protection features (im awful with breaking phones).
so immediately when i received the phone i decided to test a few things out, such as how waterproof it is supposed to be, i submerged it in a glass of water for a little while, pulled it out, dried it off, and it worked!!
ive dropped it a few times, and because of the brilliant locking feature the phone doesnt explode into a million pieces like most phones.
the screen is also supposed to be scratch proof, made from tougher glass than most, so of course i tried to scratch it, and not a mark at all! (if u need proof of this there are videos on youtube of people taking a knife to the screen without damaging it!)
i think this phone is brilliant just for these features, but it has many more too, it is incredibly easy to use as well, with mulitple home screens to put all your apps, games, widgets and shortcuts and theres is plenty enough room for everything. even if u find there isnt, there are different 'profiles' which u can switch between which give u completely new and blank home screen!
i have had the phone a while now and filled it with many programs etc and still have not had problems with freezing or lagging like a few smart phones i have used.
it may not be the smoothest and beautiful looking phone, but that is because of its water-tight features and locking system, which i think is much more practicle in everyday life than looking pretty!
all in all pretty fantastic smart phone!
