I been having some network connection issues for example I loose the signal in my house and it shows the not signal symbol. Also my phone kind of lags by just surfing through facebook and that. Until a a few days back, device was functioning normally. Now, WiFi is greyed out, and tapping it results in a hang for second or so, then stays greyed out. Bluetooth slider is set to off, when trying to engage, it turns dark blue for a moment and then resets to grey. Have reset, wiped cache, etc. Up to date install.
