Among the connectivity problems that we can find in our mobile, Bluetooth is one of the most problematic. The Samsung Galaxy S9 has a long history of problems with Bluetooth , causing many of the major functions like pairing with the vehicle or other electronic devices to fail or display erratic behavior.
There are many factors that can influence the proper functioning of the Bluetooth on the Galaxy S9. Users have shared their experiences with this problem in specialized forums. Except in specific cases where the problem is derived from a hardware failure (Bluetooth antenna)
Fix Bluetooth problems
The first logical step that we will have to take is to verify that we do not have any pending updates. The Samsung Galaxy S9 is a 2018 terminal, and has received a fair amount of patches since then. Many of them have been focused on solving known problems, including those of connectivity that affect Bluetooth. To rest easy on this aspect, we will have to go to Settings / System / System Updates.
Clear the Bluetooth cache
It is another method that works best. On many occasions the Bluetooth cache of the Galaxy S9 is saturated. For this reason it is beneficial to delete it from time to time. To do we will have to go to Settings / Applications and click on the three points above. Then we click on System Applications and finally on Bluetooth. Now we tap on storage and select clear cache.
Visibility
Another check is to verify the pairing mode and visibility. This is found within the Bluetooth options. We will have to be “visible” so that other devices can find us. Likewise, it is worth reviewing that our device allows several simultaneous connections.
Battery saving
In order to save battery, Bluetooth can be considered one of the most consuming connections. Therefore, our Galaxy S9 can activate the saving of this connectivity. This can lead to connectivity errors and interruptions, as well as pairing problems. To deactivate this option we will have to go to the Settings / Applications menu / Click on the three points / System apps and locate the Bluetooth option. We will have to disable the switch and test the connection again.
Add Bluetooth to SmartLock
This Smart Lock tool allows us to have our terminal unlocked when we connect it via Bluetooth to another device. This way, when we connect the Galaxy S9 to a music player, our car, or another device such as speakers, it can help solve connectivity problems. To start the function we must go to Settings of your Galaxy S9 and then click on Screen lock and security. Then we look for Smart Lock and click on Add trusted device , select the device and click Add.
Factory reset
The last resort that works when everything fails is to reset the phone to factory settings. This will erase all the data that we have in our terminal. But it also erases any connectivity settings, so on occasion, any corrupted files or compatibility issues that are affecting Bluetooth connectivity will be resolved. To do this we will have to go to the Settings / System / Reset menu.
