I got a samsung A13 and i run updates on it. At some point there was a update for the bluetooth and now i have a problem using my phone with hardware that have a old bluetooth in it.
Im using my phone on work where i can open house doors to old or disabled peoples houses in order to bring em food from a store that have a deal with the caretakers.
But since my bluetooth was updated, then i cant pair or connect with these door devices that automatic opens and locks the door in these houses.

Its not realy my problem since the company of these door devices wont update or upgrade ther bluetooth since they want to earn money on it from the caretaker offices.
And they need green lights from the city and so on.

But long story short..can i change my bluetooth version on my phone so i can ude it for work again or else i must buy a old used phone and i would avoid that.
 
I´m unwell. In short:
https://xdaforums.com/t/samsung-galaxy-a13-unofficial-thread.4504223/page-3 - kindly ask there
https://xdaforums.com/t/samsung-gal...es-to-root-mod-and-better-experience.4677695/ - looked interesting

My first question would be if the drivers get demoted as well if u use the "factory settings" button.

They usually have OG roms for any phone. If all fails you have to reinstall the Orignal rom-image to get the old drivers back. !And trust that the roms haven´t been moded with ill intent. I don´t think so but it has to be said.
 
The problem is that i own bluetooth devices at home that needs the newest version. so i was looking for a easy way to swap/change between old and new BT
 
I don´t see how since what you ask for is an app.

And those usually don´t get to access the System that deep.

Again, IF somebody knows they are in that developer forum.
Bite the bullet (of registering) and ask there.

Your questions nerd level is higher than i can accommodate ;-)

Good luck!
 
Have you enabled Developer Mode on you phone? You can possibly change the Bluetooth version/mode used in there.
