With the latest update of Reverse Lookup, I can’t seem to find out how to enter a manual number. Even if I configure it for manual entry as default, all I get is my call log. The menu button only offers an upsell to PLUS, a preferences page, and a Help/About page. How do I enter a manual number

If you are on Android 4.0 and up, you can access manual entry mode by pressing the handset icon in the Action Bar of the main screen.

As a general Android tip, you can long press icons in any app’s actionbar, and instead of activating that button, you will see the icons text label.
