Hello on my huawei p 20 is on the left side of the speaker not you hear nothing… Is this on the left just something like a bum or is there a real speaker '.

I bought this device so

Ke

On the left is usually the microphone behind it and the "grill" serves the symmetry.
(Do not know 100% as it is with the P20)
Is with many devices so.
It will only become stereo when it is like the Xperia X.
The earpiece above also serves as a speaker.
