Hi Everyone, A friend of mine has an A5 and it hangs too often. She says that the screen goes blank specially when she uses skype. The keyboard is giving a lot of trouble. When she types a word, half the alphabets don´t get typed. Does she need a software yet? The phone is 4 old. One more question, how can she change the software update settings from “connect to wifi” to “connect to Data” in order to update her software? Thanks in advance.
