In this guide, we will show you the steps to fix the issue of Bluetooth pairing not working on a rooted Samsung device. Gaining administrative access by rooting your device via Magisk/KernelSU/APatch opens the floodgates to a plethora of customization tweaks. From flashing modules, including the likes of LSPosed Framework and Viper4Android to installing a custom kernel, the possibilities stand endless.
However, having a rooted device also paves the way for the entry of a few issues as well. While most of you might already be aware of the Play Integrity issue wherein Basic, Device, and String Integrity Tests fail, but that isn’t the only issue associated with a rooted device. When it comes to Samsung, this list goes on and on. Thanks to the stringent security measure in the form of Knox [which is a hardware component embedded in the motherboard], once you unlock its bootloader, there’s going back.
Even if you relock the bootloader and remove the root, you’ll still have to face some of the consequences that a rooted user faces, which by the way, is quite a lot. In this regard, one of the most common issues reported by rooted Samsung users is that their Bluetooth pairing does not work along the expected lines. Whether it’s a watch, headphone, earphone, or literally any other device, they tend to pair for a few minutes before suddenly getting disconnected from the device.
In some cases, this issue occurs when upon restarting or toggling the Airplane mode on the phone. Users have tried it across different devices and different Samsung phones, so these could not be the culprit, there’s something going underneath on the OS level that is resulting in this issue. So in this guide, we will show you what exactly is this issue and how it could be rectified. Follow along.
