Overview
What this part is
The Galaxy S20 Ultra plays ringtones, alarms, speakerphone calls and media through a loudspeaker at the bottom of the phone. A drop, liquid or a blown speaker can make the sound quiet, distorted or silent.
This part replaces the bottom loudspeaker module. Before ordering, clean the speaker grille and check the sound with a different app, as a blocked grille or a software setting can cause similar problems. Call audio at the ear comes from the separate earpiece speaker.

Professional installation
How a technician fits this part
- Power the Samsung Galaxy S20 Ultra 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 on 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 play a ringtone and music at full volume 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 S20 Ultra?
Yes, if Settings › About phone shows Galaxy S20 Ultra 5G and the model number is SM-G988B.
Does it fit the Galaxy S20+?
No. The S20+ has a different loudspeaker. This part is listed for the S20 Ultra only.
Will it fix quiet call audio?
Only on speakerphone. When you hold the phone to your ear, sound comes from the earpiece speaker at the top, which is a different part.
Is it made by Samsung?
No. It is a brand new, OEM-quality loudspeaker module made to fit the Galaxy S20 Ultra 5G, and every part is tested before dispatch.
Should I fit it myself?
We recommend professional installation. The glued back cover must come off, and the battery must be disconnected safely.
How quickly will it arrive?
Orders placed before 4pm on a working day are dispatched the same day from Manchester by Royal Mail Tracked. Delivery is free on UK orders from £5.
