I bought a protective cover like this for my Galaxy S2 and was first very satisfied. The shell takes the phone to perfect and so it seems to be perfectly protected. But when I wanted to use the compass showed the vulnerability has any pocket with magnetic closure. The magnet disturbs the mobile system, which is used for many functions, is installed. example shows the compass needle always point upwards, Wasserwage apps do not work and what probably can interfere rather Navisoftware gets no movement messages and would in long tunnel can not determine current location (navigation position stops). Would mainly be a problem if the tunnel or shortly after the turn lane is that you must take. If you can do without these functions are added to these bags but white is the ideal choice to Magent shortcoming (which will be hingewisen in Samsung Instructions) I will give here only one star.
