Dear All, 

I have Samsung S9+. Couple of days before it's speaker's sound getting very low. I have to press the phone to my ear to listen the voice during call. Can anyone help in this matter? How to repair this? Do I have to visit service center?

I had this low incall volume problem with my previous owned S9 and previous Samsung phone.  Last time I just plodded on making calls and receiving them on loud speaker.  This time I tried to rectify the problem.  Firstly I tried a "soft reset" to no avail.  Then I got a new SIM card and then volume got a little better but not perfect(My sim card was 3yrs old). 
Than I got a tiny brush and cleaned the speaker at the top and then the speaker at the bottom and VOILA....bloody perfect!! 

Try cleaning the speakers with dry brush.
