Does anyone else have a issue with left speaker is much lower than the right one?

You're welcome, TopDog16! Glad we could help!

No. The holes on the bottom left are not speakers. Sound is not supposed to come out of them. The keyboard clicks come out of the bottom right and are not meant to be that loud.

So what's it for?

Yes, me and all of my friends and family. This is strange.

i bought i phon 7 plus but both speakers not working only the right one why

Have you read any of the replies above? There is but one speaker along the bottom edge. Your phone is working exactly as designed.

So then what is the point of this false speaker? It has not purpose what so ever???

It is a microphone and barometric pressure sensor.

Me Too. The left speaker seems not to be working on my iPhone 7 plus despite all the tests done with différents songs and videos.

There is no left hand speaker it is a microphone. The point is to use it for sound input.

Phew!! Thanks a lot... so hard sometimes for people to understand things. I bought it, I just had the same question, I understand and still love my apple devices :)

Thanks a lot for the explanation. That's what I needed. I thought there was an issue and there is none! I can hear perfectly well, I love the speaker and its loudness! Have a great evening.

You have a problem with your headphone jack. Get a flashlight and check it. Clean any dust or debris you find in it. If it still doesn't work you will need to get it service.
