Folks all mobile phones use RF. RF is blocked by all materials at varying degrees. Unless you want an old school telescoping antenna deal with it.
I'm not saying that this will affect me in my day to day use. If Wi-Fi signal goes down just because I pick the phone up, you bet I'll be returning this phone and going back to a 4S.
I'm not posting this thread to start a sh*tstorm or anything like that. I think the iPhone 5 is beautiful and it's the best phone I've ever used. However, I've come to expect perfection from everything Apple does, and you have to agree that they overlooked this area. I've never seen another phone lose Wi-Fi signal because of the way you hold it. Apple demoed some losing cellular signal during the iPhone 4 fiasco, but no one managed to reproduce them...
...I am posting this video because this is a genuine issue that is present with the iPhone 5 hardware.
...The iPhone 5 actually has a similar problem as I have discovered, although it is related to Wi-Fi. If you actually cover the top part of the iPhone's back (the part made of glass) in a specific way, you will actually lose Wi-Fi signal strength....
...This is very real....This problem exists regardless if you use 2.4GHz or 5GHz.
Now, this problem isn't nearly as big as the iPhone 4, because only a retard who is deliberately trying to reproduce this problem (cough) would ever hold the phone that way. The reason why I haven't discovered this bug up till now is because if you hold the phone normally, there's no way you'll completely cover the top glass area with your hands. I did it accidentally and suddenly my Wi-Fi signal vanished. That's how I discovered this bug.
...However, this Wi-Fi problem is very real, and I would just like to bring this to the attention of everyone....
