Sometimes I get a call/ text/ email come through and just get a bog standard sound, one of the stock tones. The calls can be coming through from, for example THE WIFE and it'll play a stock tone. It'll say THE WIFE on the screen, so it recognises the number. Other times it'll play the correct mp3 tone that is set for incoming calls. Same thing is happening for notifications. It may be a coinciedence but never did it before the update. Any ideas? Also, the phone seems slower now and there is a definate lag on the keyboard when typing that wasn't there before the update. Nothing extra installed.
