I have uppdated my phone. after 2 week i have some problems with my wi-fi. i can not disscunet it! even when i turn on the air-plane mode, wi-fi still works. some time when want to turn it on, it does not turn on! I repaired it and it fixed, but after 2 week i have a same proble!
If the problem is continuing after having run a repair/update I could only advise that you return the handset so that it can be assessed by an authorised repair agent.
