# Rotating Landscape and Portrait Screen

Both landscape and portrait screen orientations are supported on the PRISM mobile app. However, we have received several inquiries, such as: “Why is the broadcast locked in portrait mode even though I began streaming with my phone in landscape?” or “Why am I unable to rotate the screen orientation during a broadcast?”

If your phone is positioned horizontally but the broadcast still displays in portrait mode, this issue is likely due to the screen orientation being **locked** in your phone settings. Many users often have their phone's screen orientation locked in portrait mode. As a result, even when holding the phone horizontally, the locked orientation prevents the screen from adjusting correctly.

Additionally, if you rotate your phone in the opposite direction from the selected orientation after starting a broadcast, a notification will appear on the screen. This notification indicates that the screen orientation has changed from the preset configuration. Please note that the screen orientation cannot be adjusted once a broadcast has started.

To ensure a seamless streaming experience, make sure your phone's screen orientation is unlocked and set to the desired mode (landscape or portrait) before starting a broadcast. For further clarity, refer to the example images below, which illustrate the screen layouts for both landscape and portrait modes.

By unlocking your phone’s screen orientation, the menus will adapt to the phone’s position, allowing you to select between landscape and portrait modes before going live. Once the broadcast begins, this setting cannot be changed, so please confirm your preferred orientation beforehand.

However, in screencast mode, the screen orientation can be adjusted even after a broadcast has started. The screen will automatically rotate when you rotate your device, and viewers will see the change. Please note that the screen orientation lock on your device will still apply.
