Does anyone else get wifi issues sometimes? Like i will turn wifi on and i will be home and sometimes it wont auto connect to my router, I have to turn it off and turn it back on for it to connect. Also i feel like i have less connectivity with this phone as compared to my 4S, i only get like 2 bars of celluar service around my house while on my old 4S id get 3-4 bars of service, and i also feel like wifi connectivity isnt as strong... anyone else? Other then that the phone works great and very fast
