I'm not sure if this is a unique problem to the Stratosphere, an issue with the os, or something else altogether. I've searched through the forums for a similar thread and haven't found anything. If an answer exists elsewhere on the forums, please let me know. Occasionally, when typing a text using the physical keyboard, certain letters will bring me to different apps. For example, hitting the 'e' on the physical keyboard will bring me into my email. It used to be, when this happened, I would have to go into various apps and make sure that I 'quit' them instead of just going 'home' once I was done with the app. The past two weeks, the only things that's fixed the issue is restarting the phone. I'm wondering if anyone else has a similar problem and/or any ideas on how to keep this happening in the future.
