Is your OnePlus Open stuck in one orientation and refusing to flip when you open or rotate it? This can be especially annoying on a foldable where you expect seamless transitions between its inner and outer displays. The auto-rotate feature relies on both software settings and hardware sensors, and a glitch in either can cause it to stop responding.
Here are the most effective ways to get your screen rotation working properly again, starting with the quickest fix.
Toggle Auto-Rotate From Quick Settings
The most common reason rotation stops is that the feature was accidentally turned off. Swipe down from the top of your screen to open the Quick Settings panel. Look for the icon that looks like a phone with arrows circling it; this is the auto-rotate toggle.
If the icon appears grayed out or says "Portrait," tap it. It should turn blue or white, indicating auto-rotate is now active. Try opening your phone to the inner display or rotating it to see if it responds.
Check the Inner and Outer Display Settings
With a foldable like the Open, sometimes a setting can get confused about which display you're using. Open the Settings app and go to Display & brightness. Scroll down and look for "Auto-rotate screen."
Make sure the switch is turned on. While you're here, it's also worth checking the individual display settings under "Screen display" to ensure nothing is forcing a specific orientation for either the cover screen or the main inner display.
Restart Your OnePlus Open
A simple restart can clear out temporary software glitches that might be affecting the sensors or rotation logic. Press and hold the power button until the power menu appears on screen, then tap "Restart."
Wait for the phone to fully reboot. This is a good first step after toggling the settings, as it refreshes the system services responsible for handling rotation.
Test Rotation in Different Apps
Before digging deeper, see if the problem is app-specific. Open a few different applications, like the Gallery app to view a photo or Chrome to browse a website. Try rotating the phone while in these apps.
If rotation works in some apps but not others, the issue is likely with the non-rotating app itself. Not all apps support landscape mode, especially on the unique aspect ratio of the inner display. Check if the problematic app has an update available in the Play Store.
Update OxygenOS
Software bugs can occasionally cause sensor and rotation issues. OnePlus frequently releases updates that fix these kinds of problems. Go to Settings > About device > OxygenOS version.
Tap on the icon at the top to check for an update. If an update is available, download and install it. I've seen updates resolve quirky sensor behavior on several OnePlus models, so this is always worth a shot.
Run a Sensor Test
Your phone uses an accelerometer and gyroscope to detect movement and orientation. You can test if these are functioning correctly. Open your Phone dialer and enter *#808#. This opens the OnePlus factory test menu.
In the list, find and select "Sensor test" or something similar. The test will show live data from your sensors. Tilt and rotate your phone; you should see the values for the accelerometer and gyroscope change rapidly. If they're stuck or not responding, it could indicate a deeper sensor issue.
Check for App Interference
Sometimes, a third-party app you've installed can interfere with system-level functions like auto-rotate. Think about if the problem started after you installed a new launcher, a custom navigation app, or any utility that modifies display behavior.
Try booting into Safe Mode. This temporarily disables all third-party apps. Press and hold the power button, then tap and hold the "Power off" option on your screen until you see a prompt to reboot to Safe Mode. If auto-rotate works perfectly in Safe Mode, a downloaded app is the culprit. You'll need to uninstall recent apps one by one to find it.
Perform a Soft Reset
If a standard restart didn't help, a soft reset (or forced restart) can clear more persistent caches. Press and hold the power button for about 10 seconds or until you feel the phone vibrate and the screen goes black.
Release the button and wait for the OnePlus logo to appear as it boots up. This is different from a factory reset and won't delete any of your personal data, but it can resolve deeper system hiccups.
If you've tried all these steps and rotation is still broken, it's possible there's a physical issue with the sensors. Given the complex hinge mechanism on the Open, it's worth ensuring nothing is physically obstructing the device's movement. Avoid getting dust or debris in the hinge, as accumulated grit over time could potentially interfere with internal components.
