2.4 Remove paired devices

Sometimes, you may have a problem with the Realme 12 Pro 5G device you’re trying to connect to via Bluetooth, especially if this is a device you’ve updated. To counter and repair this, you’re going to need to remove the paired devices saved with your device and then reconnect them.

Here’s how;

From the Main Menu of your Realme 12 Pro 5G, head to Settings > Bluetooth > Connected Devices.
Turn Bluetooth on, and you’ll see all the connections your Realme 12 Pro 5G is paired with
Go through these settings and remove/delete/forget every connection on your device

2.5 Use Bluetooth in safe mode

If you’re having problems with your connection and paired devices, sometimes you may have conflicting software faults in your device that are causing the problems. If this is the case, you’ll need to boot your Realme 12 Pro 5G in Safe Mode.

The further away the Realme 12 Pro 5G devices are from each other, the less likely the connection will remain secure. As a rule of thumb, Bluetooth can work up to 100 meters, but to play it safe, always try and keep your devices under 50m apart.

2.9 Avoid interference of other Bluetooth sources

The final consideration you’ll want to think about is that Bluetooth radio waves, or wireless waves, can interfere with each other. This means they can bounce off each other or get muddled up and make things confusing from your devices.

With this in mind, you’ll want to make sure you’re limiting the amount of Bluetooth activity in the area where you’re trying to use a device. While uncommon, this could be the problem.

To fix this issue, turn off all the Bluetooth connections in the area. This includes computers, laptops, mobile phones, tablets, and any other Bluetooth devices you may have. Then, try connecting your Realme 12 Pro 5G to the Realme 12 Pro 5G device you were trying to use. If it works, you know you were experiencing Bluetooth interference.
