Confirm cropping rather than empty borders
Describe the visible problem first. Are faces, captions or controls being cut off at an edge, or does the complete picture simply have unused space around it? Those are different observations. A wish to fill every part of a wide screen can conflict with preserving the complete programme image.
Keep the same programme and orientation for a before-and-after check. If possible, note a visible object near the picture edge. That gives you something concrete to compare instead of relying on the impression that one image looks larger.
Use the documented setting for the specified phones
Nine’s instructions are to open the phone’s Settings, choose Display, open Full screen apps and disable 9Now as a full-screen app. The instruction concerns how that phone presents the app; it is not a television aspect-ratio control inside a streaming subscription.
Only apply the named route where it exists and matches your device. If a newer model has different menus, check its own current documentation rather than guessing that an unrelated display option is equivalent. Keep a note of the original setting so the change remains easy to reverse.
Verify the complete frame before changing anything else
Return to the same scene and check the objects, captions or controls previously cut off. A successful result should be judged by the complete content you can now see, not solely by whether the image touches every physical edge of the display.
If the issue remains, give 9Now support the precise phone model, operating-system version, app version and the observed cropping. Mention whether the model-specific full-screen change was available and whether it altered the result. A screenshot can help when it contains no personal notifications or account details. Do not describe every unrelated Samsung screen as affected by this one documented case.
