First, tell us WHICH PHONE you are asking about?
Second, if people press the phone button, usually it's because they want to make a phone call, hence the keypad.
Third, on my LG Optimus M Android, if I press either the "Phone" button or the "Contacts" button the "Call Log" is also available. Very clearly labelled as an easy tab. If you have an Optimus M Android, press either the Phone button or Contacts button, then hit the big Call Log tab.
Or you can download an app to do that, like Launcher Pro. You can put a shortcut to Call Log on your home screen.
From another forum:
In case anyone's still wondering, here's an easy no-app-to-install method to get a shortcut for call logs, using LauncherPro:
Long press (on home screen) -> shortcuts -> activities -> (list takes a while to load) scroll to Phone -> Click the first "Call Log" (com.sec.android.app.dialertab.calllog.LogsListAct ivity.
That should put a shortcut on the home screen..
