Understanding Speaker Issues in the Galaxy S21+

The Galaxy S21+ boasts high-quality stereo speakers, but they’re not immune to damage. Some common causes include:
- Accumulated dust and debris in the speaker grills.
- Water exposure despite IP68 water resistance.
- Software glitches from system updates.
- Physical drops causing internal damage.
Signs Your S21+ Speaker is Failing

First Steps: How to Run a Samsung Sound Test
Accessing Samsung’s Built-in Diagnostics
Before jumping to conclusions, your first move should be to run a Samsung sound test. Here’s how:
- Open the Phone app and dial
*#0*#to access the service menu. - Tap the “Speaker” or “Melody” option.
- Observe whether sound plays clearly from both speakers.
This diagnostic tool is designed to isolate whether the issue is hardware-related or software-based.
What the Samsung Sound Test Can Reveal
- No sound at all? Hardware failure is likely.
- Distorted sound? It may be debris or a blown speaker.
- One-sided audio? A potential connection issue or internal dislodgment.
Running the Samsung sound test twice—before and after attempting fixes—helps you gauge if the issue is resolved.
