How to replace bands on your Samsung Galaxy Watch 4
The band replacement process on the Samsung Galaxy Watch 4 has not changed from the previous models. If you are, however, new to Samsung Galaxy Watch, read this part.
To unlock the band from the watch body via the ‘ Spring Bar.’ Slide the strap’s spring band’s knob inward and pull the band’s end out from the watch to remove it. Repeat for the other side.
To replace the original band, insert one end of the spring bar into the hole on the side of the watch. Push the spring bar’s knob inward and release it once the strap clicks and is in place.
Make sure you test it and confirm the band is locked in place. It often isn’t!
