Auto Rotate on the Xiaomi 15 Ultra makes the screen adjust automatically when you turn the phone sideways.
When it stops working, apps stay stuck in portrait mode even when you rotate the device.
This problem is usually caused by simple settings, sensor behavior, or system restrictions that can be fixed in minutes.
Why Auto Rotate Is Not Working on the Xiaomi 15 Ultra
- Auto Rotate is turned off in Quick Settings.
- Portrait Orientation Lock is enabled.
- Motion sensors are not responding properly.
- Battery or performance restrictions are limiting system features.
- A temporary software glitch is affecting screen rotation.
1. Turn On Auto Rotate in Quick Settings
Auto Rotate is controlled by a system toggle, and it can be turned off accidentally.
When this happens, the phone will stay locked in portrait mode no matter how you rotate it.
- Swipe down from the top of the screen, and then swipe down again to expand Quick Settings.
- Find Auto rotate, and then tap it to make sure it is enabled.
2. Turn Off Portrait Orientation Lock
Portrait lock forces the screen to stay upright even when Auto Rotate is enabled.
Both settings must be aligned for rotation to work correctly.
- Swipe down from the top of the screen, and then open the Quick Settings panel.
- Look for Portrait or Rotation lock, and then tap it to turn it off.
3. Check Auto Rotate in Display Settings
Sometimes the Quick Settings toggle looks correct, but the main display setting is disabled.
Verifying this ensures the system is allowed to rotate the screen.
- Open Settings, and then tap Display.
- Find Auto rotate screen, and then make sure the switch is turned on.
4. Restart the Xiaomi 15 Ultra
A restart refreshes system services and recalibrates sensors.
This often fixes Auto Rotate issues caused by temporary glitches.
- Press and hold the Power key, and then tap Restart.
- Wait for the phone to boot up, and then test screen rotation again.
5. Remove Battery and Performance Restrictions
Aggressive battery saving can limit background system functions.
This can interfere with sensors needed for Auto Rotate.
- Open Settings, and then tap Battery.
- Disable Battery saver, and then return to test Auto Rotate.
6. Test Screen Rotation Using an App
Testing with another app helps confirm whether the issue is system wide or app specific.
Some apps do not support landscape mode.
- Open the Camera app, and then rotate the phone sideways.
- Observe the screen behavior, and then test another app like YouTube.
Auto Rotate issues on the Xiaomi 15 Ultra are usually tied to settings or temporary system behavior.
Once the correct toggles are enabled and restrictions are removed, screen rotation should work normally again.
FAQs
Why does Auto Rotate work in some apps but not others on the Xiaomi 15 Ultra?
Some apps are designed to work only in portrait mode. This is normal behavior and not a phone issue.
Can a screen protector affect Auto Rotate?
No. Auto Rotate relies on motion sensors, not touch input, so screen protectors do not affect it.
Should I worry if Auto Rotate stops working after an update?
Not usually. Updates can reset system settings, and re enabling Auto Rotate or restarting the phone often resolves the issue quickly.
