Overview
What this part is
The loudspeaker at the bottom of the Galaxy S21 FE 5G handles ringtones, alarms, notifications, speakerphone and media. A drop, liquid or long use at full volume can leave it quiet, rattling or silent.
This part replaces the loudspeaker module. Clean the speaker grille and test with another app first, as a blocked grille or a Bluetooth device still connected can seem like a speaker fault.

Professional installation
How a technician fits this part
- Power the Galaxy S21 FE 5G off and warm the edges of the back cover to soften the adhesive.
- Lift the back cover carefully and disconnect the battery before anything else.
- Remove the screws and the lower cover to reach the loudspeaker module.
- Lift out the old loudspeaker and seat the new one so its contacts line up.
- Reconnect the battery and test a ringtone, music and speakerphone before closing.
- Fit new back cover adhesive, close the phone and press evenly while it cures.
Check that the part matches the device before fitting it or removing any adhesive backing. Once a part has been fitted, it cannot be returned for a change of mind. Faulty parts are always covered.
FAQ
Frequently asked questions
Will this fit my Galaxy S21 FE 5G?
Yes, if Settings › About phone shows Galaxy S21 FE 5G and the model number is SM-G990B.
Does it fit the standard Galaxy S21?
No. The S21 FE uses a different loudspeaker. This part is listed for the S21 FE only.
Will it fix quiet calls at my ear?
No. Call audio at the ear comes from the earpiece speaker at the top of the phone. This part is the bottom loudspeaker.
Is it made by Samsung?
No. It is a brand new, OEM-quality loudspeaker module made to fit the Galaxy S21 FE 5G, and every part is tested before dispatch.
Should I fit it myself?
We recommend professional installation. The back cover is glued and the battery must be disconnected before you reach the speaker.
How quickly will it arrive?
