If I open a Browser, but them want to open an APP, or another browser, etc, ...I seem to have to go back to HOME, open the new app. is this right? Aslo..if I am in an APP, then I get a notification of email, or new txt, etc, I click on it an it opens email or messaging..etc. How do I go back to first app? Sometimes back button works but then you can;t go back to second app because there is no FORWARD button. Question : How do you toggle between Appp?
