I am assuming you are referring to "Incognito" mode in Chrome. If that is the case, this is how to get out of it...
1. Exiting the "Chrome" app will take you out of that mode.
or
2. Go to "Settings" and then "Applications Manager" or "Apps".
3. Scroll left/right to locate the "All" section.
4. Find and tap "Internet" and then tap "Clear Default".
5. Restart the phone and then tap your browser icon. It will ask what browser you wish to use and just select "Chrome".
or
6. Go to "Settings" and then "Applications Manager" or "Apps".
7. Scroll left/right to locate the "All" section.
8. Find and tap "Chrome" and then tap "Clear Data" and if necessary "Clear Cache".
NOTE: The second and third options listed will clear out your browser settings and may clear your favs, history, passwords, etc. So make sure you save all that info before doing this.
