Frequently Asked Questions

Does this buzzer solve audio issues in the upper call earpiece?
No. This component is the lower loudspeaker, dedicated to multimedia sound, ringtones and hands-free. The earpiece for private calls is located in the upper section of the Samsung Galaxy S21 Ultra 5G.

Is the loudspeaker compatible with other models in the S21 series?
No. The geometry of the loudspeaker block of the Samsung Galaxy S21 Ultra 5G is different from that present in the Galaxy S21 and Galaxy S21+, so it is not interchangeable.
