some time ago the software automatically updated. Since that time I have lost the icons to the memo function and the call list. is there a setting to restore?
I guess you are using Android 2.x. The android team changed related modules in the SDK, as a result the toolbar will no longer be displayed for Android 2.x. However Android 3.x, 4.x, 5.x are not affected.
For Android 2.x users, please click the Menu key to navigate to the Call List / Memo List screen.
