An old grandpa here: My new Samsung Galaxy S25 is not pairing with my Klipsch Bluetooth speaker. It paired fine with my much cheaper phone. The old phone is turned off. I've followed some YouTubes on standard procedures and it still won't pair.
Both the S25 and Klipsch Gig Bluetooth speaker are charged up and 12 inches apart.
The blue pairing ready light is flashing on the speaker.
The S25 readily paired with my hearing aids, Bose headset, and my Toyota Tundra.
Just guessing here. Even though your old phone is off you speaker might be holding to the pairing address. I would suggest turning the old phone on and unpair the speaker from it. By connecting Click on details Click on gear symbol And on the bottom Click on unpair. Then try the new phone.
@azhohar1 I don't think that would be the issue, since you can pair Bluetooth devices with multiple other devices (but you can only connect to one at a time). So, unless the old phone is on, it should not interfere with pairing the speaker to another phone. If the old phone *is* on (perhaps the OP didn't really turn it off), the speaker will connect to the last connected device and won't pair with another until disconnected. So, the OP would have to check that his old phone is actually off and, if not, turn it off.
