hey was wondering if any one can help me? my WiFi on my Samsung galaxy s3 will not turn on at all, it wont even search for any WiFi connections. it was working perfectly fine until this morning, i haven't done anything different or downloaded any new apps. i have tried taking out the battery and sim and restarted it multiple times but nothing has mad a difference. i have also reset it back to factory settings and still no change. i phoned Vodafone and they told me to take it into the store but would be without a phone for up to 5 days, so im hoping i can get some help and fix it myself.
