I have the above phone and love it to bits. However of late I'm receiving texts with no sound notification. It is set to ring with a "whistle" tone but no sound when arriving. It used to work so not sure why it isn't now? Have tried changing the tone but to no avail - still no sound notification. Have spoken to provider O2 but no help at all. I receive calls okay. When I click on the tones in text notification the sound I click on rings but just not when it is set to do so for incoming texts. Any help/advice would be much appreciated. Have switched phone on and off several times but no joy.
