I have galaxy s9 plus..recently i noticed that when i increases the sound ,front speakers start cracking sound,looks like fault in speaker.music sound become low quality .i keep my phone carefully ,there is no damage in it.how can i solve this cracking sound.while the down spkeaers are best with high quality sound.
hardware issue, it could be water damage, but S9+ is IP68 water resistant so better option is to visit your nearest Samsung customer care in order to diagnose the issue.
