OK, you may like to try this.
Press the menu button, then press the left button to highlight the icons on the left. Press the down button until the spanner (not the spanner with the C, the lone spanner) is selected. Then press the right button to move the highlight to the options on the right of the screen.
Then press the down button until RESET is highlighted, and press the Menu/OK button, when it asks reset REC settings, select yes and press the Menu/OK button.
Then go back to the RESET option, and answer NO to the reset REC question, NO to network, and YES to the one about Face Recognition and custom profile.
Takes many times longer to write it than actually do it
( the words may not be exactly the same, going from memory)
Then turn it off and back on again.
Select the iA position on the main mode dial and try a few photos.
If you feel like having a bit more control, such as exposure compensation, try the P mode.
I wouldn't worry about focus mode until you find you are getting good photos but need just that extra.
If that helps, could give a similar procedure for focus mode when you need it.
