The simple fix to this problem is to toggle Bluetooth a few times. This is one of the easiest troubleshooting methods you can deploy as you just have to tap on the Bluetooth button on the notification panel to kickstart it. If this method doesn’t work for you, follow the next troubleshooting method.
Airplane Mode
Yes, airplane mode can help in some cases. Although it prohibits any connection when it is engaged, it actually helps you kickstart some connectivity features which include WiFi, cellular network, and Bluetooth as well. There’s no rocket science involved here. You do exactly what’s mentioned below to complete this troubleshooting method.
- Drag down the notification pane using a downward gesture on the device.
- Tap on the “Airplane Mode” icon to engage it. This will turn off all the cellular, WiFi, and Bluetooth connection.
- Tap on it again to disengage and you should see that the cellular network is back online.
- Tap on it again a few times only to tap again to finally disengage it.
- Turn on Bluetooth and try pairing with another Bluetooth device and check if everything goes smoothly or not. If not, follow the next method.
Make sure the synchronization code is correct
Your device throws a synchronization code on your device and the other device you are connecting and it should match to confirm. If both the devices get the same pairing code, you can pair these two devices seamlessly. If not, you will have to cancel it and try again until the codes match up to allow seamless pairing. This doesn’t happen commonly but it is one of the many Oppo Reno6 and Reno6 Pro 5G Bluetooth problems that I have discovered over time. Frankly, these issues are homologous to any smartphone irrespective of the make and model.
Disconnect and Reconnect
This works if you aren’t able to connect to a said device or it keeps failing every time you try to pair, aka the Bluetooth pairing problem. Simply disconnecting and reconnecting the devices can help. Here’s how you can do it.
- Go to Settings >> Bluetooth on your device.
- Turn on the visibility and locate the Bluetooth device you are already paired with but facing issues with it.
- Long-press on it or if there are a ‘cogwheel’ or ‘three vertically stacked dots’ against the said network, tap on it.
- You should see an option called Unpair. Once you tap on it, your phone will forget if it was ever paired to that particular device ever.
- Wait for a few seconds. I would recommend clearing off all the recent apps. Follow the first and second steps.
- Tap on the Bluetooth device you want to connect to as usual.
- Check if this method works or not. If not, you don’t have a resort then continue going through the rabbit hole of troubleshooting methods I have mentioned (pun intended).
Clear data and cache
If you don’t know what’s cache (why) is, it stores some data when you open an app or website. This stored data is used to retrieve the app/website the next time which makes the process quicker. However, cache memory is always overwritten and that can introduce a number of issues such as slow performance on the device or WiFi/Bluetooth connectivity problems, and whatnot. Here’s how you can fix it up.
- Firstly, proceed to the Settings app and go towards App Management >> App List.
- Tap on the ‘2-dot icon’ on the upper-right corner of the screen and select “Show System”.
- Find Bluetooth in the list and go to its Storage Usage.
- Now, you need to tap on both “Clear Data” and “Clear Cache” to clear the same. It takes a few seconds to do it.
- Oppo smartphones running on Bluetooth 6.1 and below will have the option called “Show System Processes” instead of “Show System”.
- There is just a bit of change in the lexicon but this procedure applies to all ColorOS-powered smartphones for sure.
Restart the phone
Restarting the phone works like a charm at times as it frees up allocated resources, shuts down apps and processes back in foreground and background, and gives the hardware some time to relax. Along with that, rebooting the device clears the cache and fixes any minor or temporary glitch in the system. No doubt with those functionalities in the resume, restarting the phone is one of the most recommended troubleshooting methods no matter what issue you search for on a smartphone except those with hardware issues.
This doesn’t take rocket science to perform a reboot. Long-press on the power button, select reboot to automatically turn off the phone, and turn it on again immediately. You can also use the power button to shut down the phone, wait for a few seconds, and press the power button long enough for the Oppo logo to pop up on the screen.
Update the OS

If you are a seasoned smartphone user, you should know that outdated apps and firmware can introduce a varying degree of issues. Here, I am talking about the firmware aka Android 11-powered ColorOS 11.x on Reno6 series (other devices will have different OS versions plus custom UI).
- To check for updates for your device, go to Settings.
- Proceed to Settings >> Software Updates.
- Run the interface to check if you have received any updates or not. If yes, download it on WiFi (mobile data can also be used) and install it.
- Reboot the phone for all the changes to occur and check if updating the firmware helped or not.
Note that you are indeed using an Android smartphone and OEMs tend to support even the topnotch models for a few years only (say 2-3 years at max). This means once your device is out of support, you are unlikely to get a ColorOS update let alone Android OS updates. If you failed to get an update, in this case, proceed to the next method to try and fix the problem.
Reset System Settings
All connectivity functions on your phone run on several settings that you can find and restore to default to fix any Bluetooth, WiFi, or Mobile data issues. Here’s how you can reset phone system settings.
- First, tap on the Settings app to open it.
- Go to Additional Settings >> Backup and Reset.
- Tap on “Reset to Factory Settings >> Reset System Settings Only”.
- Check if Bluetooth is working properly or not.
Factory Reset

This is the last thing you would do before walking into a service center nearby. Perhaps what you must know here before proceeding is the fact that once you go through with it, there’s no coming back. You have certainly lost all the data not backed up unless you know how to recover lost or deleted data. Here’s how you can perform a factory reset on your device using a non-invasive method.
- First up, open the Settings application on your device.
- Next, tap on Additional Settings.
- Navigate the page to find and click on Backup and reset.
- Next, click on “Erase all data (factory reset)”.
- You will get a prompt asking you to confirm if you want to delete the data or not. Agree here.
- Enter the password/PIN as asked and proceed by tapping on “Erase all data”.
- After you are done restoring the phone to its default state, reboot the phone and set it up as a new smartphone.
- Check if the Oppo Reno6 and Reno6 Pro 5G Bluetooth Problem is gone or not.
Get official’s help
Assuming that you did whatever it takes to fix any software or network-related issue causing Bluetooth on your Reno6 series smartphones to behave abnormally, the only resort is to get the hardware diagnosed for an issue and fix it. A professional at an authorized service center will be able to help you find what’s wrong and quote a price to fix it. However, you have a choice between an authorized and a local service center where the latter is way cheaper.
Closing Words
No doubt both Oppo Reno6 and Reno6 Pro 5G smartphones are state-of-the-art pieces of excellence, however, Bluetooth issues could hit any device and these two models are no exception. I hope that using the aforementioned troubleshooting methods, you were able to fix the Bluetooth problem once and for all.
