It has been almost a year since the OnePlus 9 and 9 Pro were released. As with most smartphones, there were plenty of bugs after launch that OnePlus was able to fix with software updates. Unfortunately, there are still a few OnePlus 9 issues with the series, especially after OnePlus started rolling out Oxygen OS 12 (based on Android 12) in December last year. Here are some problems with OnePlus 9 and OnePlus 9 Pro and how to fix them!

Our verdict: OnePlus 9 review | OnePlus 9 Pro Review

Problem #1: OnePlus 9 app notification issues

Some OnePlus 9 and 9 Pro owners will see delayed notifications or only receive notifications when they open the app.

Possible solutions:

If you’re noticing delayed notifications, it could be because of the phone’s battery optimizer feature. Go to Settings > Battery > Battery Optimization. Find the apps that you are experiencing this problem with. Tap ‘Don’t optimize’. If you want to make sure that an app continues to run in the background, you can ‘lock’ the app. Open the app. Then launch the Recent Apps page. Long press the app window and select “Lock” from the popup menu. Once done, you can remove it by going through the same process and tapping “Unlock”. Some users have found that disabling the “adaptive notifications” setting works. Go to Settings > Apps & notifications > Dedicated access for apps > Adaptive notifications and select None. Problems with app notifications are software related so make sure to keep the app and the phone’s operating system up to date to the latest versions.

Problem #2: Alarm not working

One of the more common OnePlus 9 and 9 Pro issues since the update to Oxygen OS 12 has to do with the alarm clock. Some users cannot disable an alarm from the lock screen. More worryingly, the alarm notification only appears on the lock screen, but doesn’t actually ring.

Possible solutions:

You can try clearing app data and cache. Go to Settings > Apps & notifications and open the app list. Select the Clock app, then go to ‘Storage & Cache’. Tap “Clear Storage” and “Clear Cache”. Some users say that performing a factory reset after installing the latest version of Oxygen OS helps to fix some common bugs. It’s not the best solution as you’ll lose all your data and have to reset the phone, but it’s worth considering if you’re experiencing a lot of issues after the update. If you see a lot of bugs after the OS update, you may want to roll back to Oxygen OS 11 until some of these issues are fixed. OnePlus has a guide on how to do this on their forums.

Problem #3: USB-C earphones or dongle not working on OnePlus 9

Some users are having a problem using their USB-C earphones or dongle after Oxygen OS 12 update.

Possible solutions:

This is not a bug but is caused by the OTG setting being disabled during the update. Go to Settings > System and enable “OTG Storage”.

Problem #4: Android Auto Problems

Problems with Android Auto are common in most smartphones. Unsurprisingly, this is also the case with the OnePlus 9 and 9 Pro.

Possible solutions:

You may experience connectivity issues with Android Auto if you used the OnePlus Switch feature to set up your new phone. If so, find the app in the Google Play Store, uninstall it and download it again. You may no longer see the Android Auto app in your app drawer. If there’s a problem with app settings, you’ll find them tucked away in phone settings. Go to Settings > Bluetooth & Device Connection > Android Auto. Everything you need should be there. Check the cable you are using and buy a new one if necessary. If you often see disconnects, it could be a hardware problem. On the other hand, if you’re using Android Auto Wireless, you may want to switch to a wired connection for more stability.

Problem #5: Unable to uninstall Google Discover

OnePlus 9 and 9 Pro owners who have upgraded their phones to Oxygen OS 12 will find that they cannot delete the Google Discover page (swipe on the home screen). This is not a bug but a feature. With Oxygen OS 12, the option to remove this feature has been removed. You can still remove any cards that appear by going through your Google settings, but you’ll still see a search bar at the top.

Problem #6: Camera issues

Some people are noticing several camera issues with the OnePlus 9 and 9 Pro after the Android 12 update. Images appear blurry and out of focus and get worse when you zoom in on a subject.

Possible solutions:

You can try clearing app data and cache. Go to Settings > Apps & notifications and open the app list. Select the Camera app, then go to ‘Storage & Cache’. Tap “Clear Storage” and “Clear Cache”. Some users say that performing a factory reset after installing the latest version of Oxygen OS helps to fix some common bugs. It’s not the best solution as you’ll lose all your data and have to reset the phone, but it’s worth considering if you’re experiencing a lot of issues after the update. If you see a lot of bugs after the OS update, it’s best to roll back to an earlier version until some of these issues are fixed. OnePlus has a guide on how to do this on their forums. This software issue will likely be resolved in an upcoming update.

Problem #7: Connection Problems

You may occasionally encounter connectivity issues with Wi-Fi and Bluetooth. In particular, owners of OnePlus 9 and 9 Pro are seeing Bluetooth connectivity issues that will only be resolved with a software update. Until then, you can try these general troubleshooting tips.

Wi-Fi issues

Turn off the device and router for at least ten seconds, then turn them back on and try to connect again. Go to Settings > Battery > Power Saver and make sure this option is turned off. Try the Wi-Fi connection again. Go to Settings > Wi-Fi & Network, long press the connection name and tap “Forget”. Now re-enter the data and try again. Make sure the firmware of the Wi-Fi router is up to date. Make sure that the applications and software on the device are up to date. Go to your Wi-Fi network settings (the gear icon next to its name and tap Advanced) and note your device’s MAC address and make sure it can access it in the router’s MAC filter.

Bluetooth issues

If you have any problems connecting to the vehicle, please refer to the device and vehicle manufacturer’s manual and reset your connections. Make sure not to miss an essential part of the connection process. Some Bluetooth devices have unique instructions. Go to Settings > Bluetooth and device connection and make sure nothing needs to be changed. Go to Settings > Bluetooth and device connection, delete all previous pairings and set them up again. Don’t forget to remove any devices in this list that you no longer connect to.

Guides: Factory Reset, Boot into Safe Mode

Factory settings

Make sure to backup all critical files and data as this step will delete everything. When the phone is on: Go to Settings > System > Reset options and at the top and “Erase all data (factory reset)”. If the phone is turned off or stuck: Press and hold the volume down key and the power button at the same time until the device vibrates and the Android recovery screen appears. First, you may need to select a language using the volume keys to navigate the menu and press the power button to select. Scroll down to ‘Clear data’ and select ‘Clear all’. Before completing the process, you will be prompted for a final confirmation.

Boot in safe mode

When the phone is on: Press and hold the power button until the power options appear. Long press the “Disable” option until you see a prompt that says “Boot in Safe Mode”. Tap “OK”. When the phone is turned off: Press and hold the power button until the phone vibrates and the OnePlus logo appears on the screen. With the logo still on the screen, press and hold the Volume Down key. Keep pressing the Volume Down button until you see “Safe Mode” appear in the lower left corner.
