I'm not sure how to keyword search this, so if this has already been asked and answered I apologize.
Occasionally, my phone seems to get confused. I will unlock the screen and tap the message button and instead of opening my messages it takes me to the last app I had open. I have to either turn the phone off and then back on and/or pull the battery.
I've only had the phone for a little over a week. It a HTC Eris. Does anyone know what this is and how to fix it??
