S21 upgrade speaker issues battery life

[thappy]

Since new upgrade on my S21 there's a problem with the speakers ..they sound odd both on speaker mode and ordinary calls.

Also, since same upgrade battery life diminished greatly...what's going on?

Samsung was this and upgrade or downgrade?

Have you got Dolby Atmos turned on? From my experience, this improves the sound quality.

It was all fine before the upgrade...I'll have a look at what you suggested thank you.
