How does this work?
The main reason for your smartphone’s speaker volume going low is because there is a cloud of dust built up in the grill. If you clear this dust from the grill then your smartphone will sound normal and louder the way it was before. The only problem to clean that grill is that the grill holes are small and even if you try to put something in it, the dust will be pushed further inside. What Xiaomi did, is that they created a feature that plays a high pitch noise to clear the dust off the speaker grill.
Step to Clear the Speaker on Xiaomi Smartphones
Tap the smartphone
Once you are done with that, you can shake off the smartphone to clear the dust which came loose after that. You can also tap the smartphone lightly in the upright position on a wooden table so the dust will come out. Do not hit the smartphone too hard on the surface or it can damage the device. If your smartphone’s speaker is still on the low volume then try these settings 2 to 4 times including the tapping. If the situation is still the same then you should take your smartphone to the service center. https://www.tiktok.com/@gadgetstouse/video/6824597172948897026
