Cannot add or resize apps and widgets on the Galaxy Z TriFold

The Home screen on the Galaxy Z TriFold operates in both landscape and portrait modes. If one mode is full, you won't be able to add apps or widgets to the other mode, even if it appears to have space.

To successfully add apps and widgets to your Galaxy Z TriFold Home screen, follow the steps in this guide to ensure space availability in both landscape and portrait modes.

By default, the Galaxy Z TriFold is set to Auto rotate, allowing you to seamlessly switch between landscape and portrait modes by turning your device sideways and back upright. To ensure a smooth experience, always check that there is sufficient space on both the landscape and portrait Home screens for adding apps and widgets.

If one mode appears full, free up space by removing unused apps or widgets and rearranging items. 

• Remove apps and widgets: Touch and hold an app or widget on the Home screen until a pop-up menu appears, and then tap Remove.
  
• Rearrange items: Touch and hold an app or widget, and then drag it into another portion of the screen, or into another Home screen.
  
• Combine apps into a folder: Touch and hold an app, and then drag it on top of another app and release.
  
• Resize widgets: Widgets that can be resized will have a dot in the center of the outline. Touch and hold the dot and drag it to resize the widget.
  
• Stack widgets: Touch and hold a widget on the Home screen, then tap Create stack. Select a new widget to add to the stack, choose your desired widget option, and then tap Add.
  

Swipe up or down on the Home screen to access the Apps screen. Then, perform one of the following:

• Touch and hold an app until a menu displays, then tap Add to Home.
  
• Touch and hold an app until the Home screen is displayed, then release it in your desired location.
  
• Touch and hold an app, drag it to the top or bottom of the screen, and then release the app in your desired location.
  

1. Pinch or touch and hold a Home screen to enter Edit mode.
2. Tap Widgets, swipe to the desired widget, and tap Add.
