This morning I had to update my Samsung S20 to the lasted version, but I noticed that the sound system is broken once I play music youtube videos, or FB / Instagram videos,
The last version is G980FXXUGHWCG/G980FOXMGHWCG/G980FXXUGHWCG , One UI 5.1.
I take it you mean the phones speakers If you go into the support section on the Samsung Members App. Go into phone diagnostics You have a test in there for the speakers. If in the test both speakers work. It could be a software issue that Wiping the Partition Cashe can help with. While you are in the recovery menu, you can repair apps as well See if this helps
