When ever I use most of the applications on my phone including email and the internet, when I close out of them or hit the home screen button the screen goes white showing the green HTC logo on it then it loads like it would when turning the phone on. It will then displays the grey box that says loading with the spinning wheel thing. I figured maybe it was a memory issue so I do clean the cache regularly and that doesn't seem to help. I also us a task killer set to take care of the apps that do not need to constantly be running. As far as internal storage I have 236mb free with some apps stored of my memory card to help save space. Any information on this would be of great help. Its something that over time has become a real pain to deal with.
