The wireless problem: The 4s often does not connect to my Fritz box although I am close and have full reception. It's annoying in the long run, always wait up to 5 minutes until the 4s connects.
I am often on the Internet dependent (School o. Ä.) And since it is not acceptable for a smartphone in this price range that a wireless problem.
But otherwise this is 4s a top product with just one Macke.
