Stay Away from Metal back cover and bumper frame
For ppl wondering if this affects your wifi, I can confirm it does. Here is my story. I bought this metal case (Green
and then this metal frame
I used both together and I had no wifi issues untill after 3wks of use. My wifi started to disconnect almost all the time and then to reconnect takes like ages. I tried everything, I thought it was Lima and Wifi auto on that am using that was causing it, I unistalled them, factory reset and even flashed a fresh stock ROM, still my wifi won't connect. Reluctantly, I removed the case and it connected but the signal was so poor that I cannot open a page.
To cut the long story short, it got to a point that my S3 will not connect to a wifi from a distance greater that 1-2m away from the router. But as soon as I place my phone on top of my router it connects.
Again I said maybe its my router, I decided to tether with the phone to see how good the signal would be, to and behold, the signal was so weak that nothing was able to connect to it, that was when I knew my wifi antenna is fried.
However, since I used the both together, I can't really say for sure that either one of them caused it independently, so the only way to stay safe is to not use any of them ever again.
I didn't notice any issues with my network connection but can't say such about GPS bcos I hardly use it.
Well all thanks to warranty, I returned it to Handtec and got a replacement though am still furious about the DHL freight cost that I paid for the return.
Pls don't use metal back cover if you love your wifi.
