I am unable to retrieve text messages. When I recieve a notification that I have a text, I click on the text msg icon and my screen goes white and I am unable to perform any functions while it is in this mode. After about 30 seconds, the phone screen restores to my 'home page.' All other apps on the phone work fine. I think what triggered this glitch was a friend sending me a text with several pictures and this may have jammed my text msg. any ideas for resolving this issue are greatly appreciated.
