Today, we’re addressing a common concern among Xiaomi Redmi Note Nine users – low call volume. A customer reached out to us, frustrated with the difficulty of hearing calls clearly, even with the volume cranked up to the maximum. 

To start, let’s dial the customer’s number and see if the call quality is indeed poor despite the volume being set to its maximum level. It’s clear that there’s an issue. But what could be causing it?

Upon inspecting the phone’s speaker, we find it is clogged with dust.

We’re about to guide you through a quick fix that will have your Redmi Note Nine sounding crystal clear in no time.

The Solution: Cleaning the Speaker:

To resolve the low volume issue, turn off the phone or simply keep the screen off. Grab a brush and dip it in isopropyl alcohol. Holding the phone upside down, delicately apply the brush to the speaker holes. Now, take a lint-free cloth, tear off a small piece, and gently wipe the speaker area. Voila! The speaker holes are now free of obstruction.

Testing the Fix:

Let’s put our solution to the test. Dialling the customer care number again, we’re greeted with a clear and loud response. The volume issue is officially resolved!

We hope this step-by-step guide has been helpful in tackling the low volume problem during calls on your Redmi Note Nine smartphone.
