Whenever I am in an app, email, text etc.. and when I press the home key to take me back to my home screen my phone goes back to the white screen with the HTC logo and then my home screen says 'loading' for about 30 secs before returning to normal. Anyone else have this problem? Is it a fault with this phone? Another issue is that my signal is always poor using this phone, its not my area as my previous phone was perfect. My Sensation is 3 weeks old.
