How to replace a Samsung Bud FE and why sometimes only one shows up.

You will need to use an Android device with the Samsung Wearable App to successfully connect replacement Buds (Samsung Galaxy Buds, Buds2, Buds Pro, Buds2 Pro, Buds FE, Buds+)

When you try to couple/connect your replacement Samsung Bud with your old Bud, it might be that only one, left or right shows up in the Wearable App. The reason is that the firmware versions between the two buds differ and might not even be up-to-date. You will need to use the update function of the Wearable App to get both Buds to the same, latest firmware version. You might have to reset the Buds 2-3 times in the process.
