Turn your volume all the way up, then press Start.
Which speaker plays?
How does each range sound?
Listen for rattling, crackling or a range that drops out. Many phones have a single loudspeaker, so left and right may both come from the same place.
Galaxy phones support vibration in the browser, which adds a little extra shake to every pulse.
Turn off Dolby Atmos and any equaliser in Settings, Sounds and vibration, Sound quality and effects, so the tone plays exactly as generated.
Take off the case and disconnect Galaxy Buds or other Bluetooth audio.
Leave Vibrate with the pulses switched on, hold the bottom edge down and press Start.
Most recent Galaxy phones are stereo, with the earpiece as the second speaker. Check both in the speaker test.
Galaxy phones block wired charging when they sense moisture in the USB-C port. Unplug the cable, shake the phone gently with the port facing down, and let it air-dry before charging. The alert clears by itself once the port is dry. Wireless charging may still work in the meantime.
The bottom speaker grille on most Galaxy phones is a row of small holes beside the USB-C port, right where pocket lint collects. If the sound is dull rather than wet, switch to Dust shake, then brush across the holes with a soft, dry toothbrush.

Yes. The tool runs in Chrome and Samsung Internet on any Galaxy phone. The steps are the same; only the grille position varies slightly by model.
It adds a small mechanical shake in time with the pulses. The sound does most of the work, but there’s no downside to leaving it on.
Don’t play cleaning tones with earbuds in your ears. Clean Buds by hand with a dry swab and a soft brush.
Some moisture can sit deep in the port. Leave it unplugged in a dry place for a while. If the alert never clears, have the port checked.
