When I turn on my Wi-Fi it just says "Searching for avaible Wi-Fi networks" and stays that way, also when I try to turn on my bluetooh it just says "Turning bluetooth on...". I also can not install my MMS & Internet settings. This happened when I turned off my mobile device and than turned it back on. Also when I turned it on I had to wait 30-60 minutes to get to the home screen becouse it just stays displaying SONY on my screen for a longer time(30-60 min).
