Bluetooth doesn't work on new phone but on old one it works

[Fabi0011]

Good Evening,
I have an app which has a list picker where it lists the bluetooth devices and connects to them. On my old Phone (Samsung Galaxy J6 Android 10) it works perfectly but on this one (Samsung Galaxy S10 Android 12) it just doesn't show the bluetooth devices.
Thanks for your help!

Dear @Fabi0011 welcome to the Community,
problems related to the BT comm's with the newest Android versions are treated almost every day on the forum.
Probably you can find a solution in one of those posts. For example this:

BLE extension - Date Built: 2023-02-23 - permissions & connecting issuses on Android 12+

Quite a few users are currently having problems with the (new) BLE extension. Here is a test app. Test it on your devices and post screenshots before and after scanning and connecting. Location permission is requested automatically (so disable it before testing). [grafik] [grafik] EDIT: See also here:

Though from your blocks it seems that you aren't using a BLE, but a classic BT, please be aware that for new Android versions it is mandatory to enable the (fine) location on your phone.
