Why Does Bluetooth Connection Error Occur?
There are several reasons why your Note9 has problems connecting to another Bluetooth device. Here are some of the most common ones:
- Incompatibility problem
- Range between devices
- Weak power
- Devices are not configured correctly for pairing
- Interference
- Software failure
The incompatibility between Bluetooth devices is real. Before trying to solve some problems with your Galaxy Note9 or another Bluetooth device, it is advisable to know if there is a risk of incompatibility. If both devices can connect before, you can skip this part. However, if you connect your Note9 for the first time to the Bluetooth of your car, for example, there is a real risk that there is a problem of incompatibility between them.
Note that there is no universal standard for Bluetooth devices. Car manufacturers tend to use a third-party Bluetooth system in their vehicles and sometimes these systems may be obsolete. Although older Bluetooth devices can still work with the latest Bluetooth systems and can be periodically updated on phones, the profiles they use may not work 100%. As a result, some cars that use older Bluetooth technology may not be able to pair or use a function that previously worked when a phone receives an update.
The new Bluetooth devices are designed to work with older versions of Bluetooth, but sometimes there may be problems. Not all manufacturers can support all Bluetooth devices. Then, it’s always possible that something is not working properly.
Phones like the Galaxy Note9 are compatible with Bluetooth Smart Ready, which means that it uses the latest Bluetooth 4.0 technology to connect to other Bluetooth Smart devices. If your Note9 is not paired with your car or Bluetooth device, the device or your car may not be compatible with Bluetooth Smart. Unfortunately, you can not do anything about it and you must update this device if you want to use your Note9 to transmit information.
Prepare the device to match: This is essential Before pairing, make sure both devices are configured to receive the pairing request from the other by enabling them. If only one device is turned on, the other will obviously not detect it. This may seem obvious, but many people who have Bluetooth pairing issues cannot check it. Depending on the device you are trying to connect to your Note9, the LEDs are the best way to tell if everything is set up or not.
Distance matters: Like any other wireless device, proximity is an important consideration when pairing Bluetooth devices with your Note9. This may not apply to Bluetooth cases in the car, but you should consider this if you are trying to handle a much larger space, such as in a building or a house. Most Bluetooth connections are only good if they are in the 30-foot range. If you are working in a house or a large building and there is a problem with Bluetooth pairing, check the distance between the devices. Obstacles such as glass, metal surfaces and thick reinforced concrete walls can also significantly affect the Bluetooth signal. When pairing, try to bring the two devices as close as possible.
If you are trying to work with a fixed Bluetooth device, such as a speaker in your home, you may need to consider other factors.
In some cases, wifi signals can also affect Bluetooth. If you have a portable wifi device, try turning it off to see if it makes a difference.
How to solve the problem of Bluetooth pairing on your Galaxy Note 9
To solve problems on your device, here’s what you can try:
A forced reboot of the system is one way to solve temporary Bluetooth errors. In this case, try to simulate the effects of a battery discharge by doing the following:
- Press and hold the Power / Volume + Volume buttons for about 10 seconds or until the unit turns off. Wait a few seconds until the maintenance start mode screen appears.
- On the Maintenance Start Mode screen, select Normal Startup. You can use the volume buttons to scroll through the available options and the lower left button (below the volume buttons) to select it. Wait 90 seconds for the restart to complete.
Restart the network: It is essential that your Note9 has all the correct network settings. You can do this by deleting the current network configuration. Here is how it is done:
- On the Home screen, drag a blank space to open the Applications panel.
- Tap Settings> General Administration> Reset> Reset Network Settings.
- Press RESET SETTINGS.
- If you have set a PIN, enter it.
- Press RESET SETTINGS. When finished, a confirmation window will appear.
Install Updates: This reduces the chance of your device receiving errors in applications and software. Some network problems, including Bluetooth mistakes, may be due to poor coding that only an update can correct. Make sure to keep Android and apps up to date.
Clear the cache partition: Some forms of network errors and caused by the corrupted system cache. Try emptying the cache partition of your device to keep the system cache in good shape. Here’s what you need to do:
- Turn off the device.
- Hold down the Volume Up and Bixby buttons, then press and hold the Power key.
- When the green Android logo appears, release all keys (“Install System Update” will appear for about 30 to 60 seconds before displaying the Android system recovery menu options).
- Press the key to lower the volume several times to highlight “Clear Cache Partition.”
- Press the power button to select.
- Press to decrease the volume until “yes” is highlighted, then press the power button.
- When the cache erase partition is complete, “Restart System Now” is highlighted.
- Press the power button to restart the device.
Format/Reset your device: This is a bit extreme for a Bluetooth problem, but if you think there is a problem with the software, you can erase the device. To avoid losing your personal information, be sure to make a quick backup. You can follow this link to learn how to create a backup with Smart Switch.

- Press the power button to select.
- Press the key to decrease the volume until “Yes: delete all user data” is highlighted.
