Problems with auto-rotate, Wi-Fi, camera, and more

Annoyance: Device doesn’t auto-rotate

When changing the phone’s orientation from portrait (vertical) to landscape (horizontal), the display does not rotate as it should, even when the feature that allows the display to automatically change is enabled. This  problem has been talked about on the OnePlus and XDA Developers forums.

Potential solutions:

  • Some have seen the auto-rotate feature work just fine after a quick restart. Turn your phone off and on again to see if the problem fixes itself.
  • If the problem started after installing a certain app, or a series of apps, consider uninstalling them one at a time to see if that was the cause of the issue.
  • There are apps on the Google Play Store like GPS Status & Toolbox that will allow you to see if all of a devices sensors are working, and re-calibrate them if necessary. Similarly, there are apps like Rotation Control that let users control and adjust the screen orientation, as well as prevent other apps from changing it.
  • If the problem continues, reach out to OnePlus Support to get a replacement smartphone.

Issue: Can’t connect to Wi-Fi

All smartphones run into this particular issue at some point or another. Either your connection is terrible, or a connection can’t be made at all. Fortunately, the solutions remain the same and will help those on the OnePlus forums that are suffering from this particular issue.

Potential solutions:

  • The easiest thing to try is turning your phone off and on again and seeing if the connection works or improves. You should also try restarting your router, if restarting your phone didn’t change anything.
  • Go to your Wi-Fi settings and remove or forget the network you’re currently connected to, or trying to connect to. Then, enter the required details again to retry the connection.
  • OnePlus Support has two additional suggestions, following the release of OxygenOS 4.0.3:
    • If you experience frequent Wi-Fi disconnections, please go to Settings > Wi-Fi > Configure Wi-Fi. Scroll to bottom of the page and check the IP address format (IPv4 = Single line, IPv6 = Multiple lines). If the IP address is IPv6 based, then turn off the IPv6 Support toggle and see if the disconnections stop.
    • If you experience frequent Wi-Fi disconnections while switching between Wi-Fi and data, please try turning off the Smart Wi-Fi Switcher in Settings > Wi-Fi > Configure Wi-Fi and see if the disconnections stop.
  • If your device is constantly trying and failing to find a network connection, go to Settings > Mobile Networks > Network Operators and manually choose a network. This may also reduce your phone’s battery consumption.
  • Head into your settings and disable Power Saving Mode, which affects your Wi-Fi performance.
  • Go to Settings > About Phone and locate the device’s MAC address and make sure your router allows it.
  • You can also try performing a factory reset if nothing else has worked for you — some have managed to alleviate their Wi-Fi issues after doing this. Back up your data first, then go to Settings > Backup & Reset > Factory data reset > Reset phone > Erase everything.

Problem: Camera app doesn’t work or basic functions are unresponsive

The camera app that comes pre-installed on the OnePlus 3 doesn’t always work as it should. It doesn’t seem to properly take photos — or doesn’t take them at all — and the shutter button is unresponsive. Even using the volume down button to take a photo fails to work. The OnePlus 3T has also had problems with the camera app, including one where changed settings are not saved.

Official solution:

  • Previous updates to OxygenOS, such as update 3.2.1 for OnePlus 3, and update 3.5.3 for the OnePlus 3T added improvements to various aspects of the camera app. The most recent update for both smartphones, 4.0.3, contains even more improvements. Specifically, “increased stability of the Camera app,” and “optimized exposure when taking night time photos.” Consider updating to version 4.0.3 if your camera isn’t performing to the best of its ability.


  • There are tons of alternative camera apps you can download and use on your OnePlus 3/3T, such as Open Camera and Camera MX.

Potential solutions:

  • Wiping the cache partition has worked for some users. You can do this by turning the phone completely off, then turn it back on while pressing and holding the volume down button until the phone vibrates. Your phone will start in Simple Recovery mode, and you’ll need to use the volume buttons to navigate to the Wipe Cache Partition option and the power button to select it. Once the process is done, you’ll be told the cache wipe is complete.
  • Perform a factory reset, then test the camera again.
  • Reach out to OnePlus support, as it may be a hardware issue you’re ill-equipped to deal with.

Problem: Screen timeout doesn’t turn off display

Screen timeout is a feature of the OnePlus 3 that will dim the display of the device after a predetermined amount of time, or turn it off entirely. Some owners’ devices are not dimming as they should, which could lead to battery drain.

Potential solutions:

  • Restart your device.
  • Go to Settings > Display > Screen timeout and change how much time should pass before the screen is turned off.
  • Clear the cache after updating – Turning the phone off, then turn it back on while pressing and holding the volume down button until the phone vibrates. Your phone will start in Simple Recovery mode, and you’ll need to use the volume buttons to navigate to the Wipe Cache Partition option and the power button to select it. Once the process is done, you’ll be told the cache wipe is complete.
  • Try a factory reset.
