How to Fix Xiaomi Phone Screen Flickering Issue

Xiaomi speaker not working or producing crackling audio is usually caused by blocked speaker holes, Bluetooth audio routing, HyperOS sound glitches, moisture, or hardware damage. The fastest fix is to test audio in Safe mode, clean the speaker grille, disable Bluetooth, restart the phone, and install pending system updates before assuming speaker failure.

Steps

Check basic audio settings.

Turn volume up, disable Silent mode, and disconnect Bluetooth devices. Audio often routes to earbuds, watches, or car systems instead of the Xiaomi speaker.
Clean the speaker area carefully.

Remove dust, lint, or pocket debris from the bottom speaker grille with a soft brush. Blocked openings often cause low sound, muffled output, or speaker crackling on HyperOS.
Restart and test in Safe mode.

Restart the device, then test sound with a ringtone, speakerphone call, and video. Safe mode helps confirm whether a third-party app is interfering with audio processing.
Update HyperOS and reset sound-related settings.

Install available system updates. If the problem started after an update, reset app preferences and sound settings, then retest media, notifications, and calls.
Check for moisture or hardware damage.

If crackling started after water exposure or a drop, let the phone dry fully and avoid charging immediately. Persistent distortion usually points to speaker module damage.

Common Issues and Fixes

Speaker works in calls but not for media	An app conflict or media output bug	Test in Safe mode and clear cache for affected media apps.
Problem started after HyperOS update	A temporary software bug	Install the next patch, restart, and reset app preferences if speaker crackling on HyperOS continues.
Very low sound after water or humidity	Trapped moisture	Power off the device, dry it in a ventilated area, and retest after several hours.

Quick Tips

Phone case obstruction: A phone case can partly cover the bottom speaker and make Xiaomi speaker not working seem worse than it is.
Stereo speaker design: Stereo Xiaomi models may use one main bottom speaker and one earpiece speaker. Uneven sound is normal on some apps.
App-specific crackling: Crackling in only one app often means bad source audio, not speaker damage.
Factory reset timing: Factory reset should be the last software step after backup, because hardware faults will not improve after a reset.

🤔Note:

Before assuming the speaker is broken, compare sound in ringtones, speakerphone calls, videos, and voice recordings. If only one app has crackling or low sound, the issue is more likely related to that app or its audio source than the Xiaomi speaker itself.

Why does Xiaomi speaker crackle only during calls?

Call crackling often comes from network instability, microphone feedback, or a damaged earpiece speaker. Test speakerphone, wired earbuds, and voice recordings to isolate the fault.

When is repair needed for fix speaker Xiaomi problems?

Repair is usually needed when sound stays distorted after cleaning, Safe mode testing, updates, and drying. Rattling, buzzing, or complete silence after a drop often indicates hardware failure.

💡Protip:

Before a factory reset or service visit, a device manager such as Dr.Fone can help export photos, videos, and files so data stays accessible during troubleshooting or repair.
