How to change the icon/avatar/photo of the account in the Android app?

To add an account photo:

1. Open the navigator.
2. Tap on the panel above the calendar.
3. Tap on the user icon (located at the top of the window).
4. In the appeared window, tap on the user icon again.
5. In the next window, choose a photo source. Tap on ‘Camera’ or ‘Choose a file.’
6. Take a photo or select a file from your device.
7. The user icon will be replaced by the photo.
8. Tap ‘Save.’

Changing an already added account photo follows the same procedure.
