The Galaxy S23+ has one of the louder speakers in its family, so a speaker that has become quiet or muffled is rarely the speaker itself. It is usually the grille, the case, or an output setting. Three quick tests decide it. First, play a clip with the phone out of its case; if it improves, the case is the cause. Second, open the media output panel and check the sound is going to the phone and not to a paired TV or car. Third, run the speaker test in Samsung Members. Only if all three point at the phone is a repair worth booking.

Before you touch a setting
Record this first — changing settings destroys the evidence
- Whether the sound is quiet, one-sided or distorted when you hold the S23+ in landscape
- Which of media, ringtone and call audio is affected
- Whether a Bluetooth car or TV is still connected
- The case fitted, and whether it folds over the bottom edge

Model-specific
What is true of this model and not of its siblings
- Case design
- The S23+'s bottom grille sits close to the edge, so wallet-style and folio cases that fold over the edge muffle it.
- Loudness
- With a bigger body than the S23, the S23+ has a louder, fuller speaker, so a quiet one is a symptom worth chasing.
- What a failing speaker sounds like
- A speaker with a damaged cone crackles on bass even at low volume, while a clogged grille sounds muffled but clean; the difference tells you whether to clean or repair.
- Phone against paired devices
- A phone that is connected to a car or TV over Bluetooth plays silently on its own speaker, which is a common reason for no sound at all.
- Loudness through the years
- The S23+ speakers are tuned for volume, and a loss of more than a third of the loudness over three years is usually dust, not wear.
- Soft cleaning
- A soft brush, a dry toothbrush used lightly, and a short blast from a hand rubber bulb are safe; compressed air from a can is not.
Stop boundary
When this stops being a self-service repair
- !A failed Samsung Members speaker test with the case off is a repair on the S23+
- !After water, let the phone dry at room temperature for a day before booking
- !If only one app is silent, reinstall that app
