I received the Android 10 software and headphone firmware updates from Sprint this morning. All went well until I plugged in my headphones and received a firmware update. This update caused a severe decline in the sound quality!! I checked the sound on my wired and Bluetooth headphones and it vacillates up and down, at times the sound quality became muffled or distorted or gargly. Before this long overdue and highly anticipated software update, I had no problems with the sound. Not only did the sound quality decline, but the volume levels have diminished also. SAMSUNG - PLEASE PROVIDE A FIX FOR THIS SOUND BUG! I checked all my adjustments and I updated the sound profile to no avail. This intermittent up and down, in and out, muffled, distorted, gargling sound is tormenting! My music listening experience is vital. If I could revert back to Android 9, I would do so immediately! SAMSUNG, IF YOU'RE READING THIS, PLEASE PROVIDE A FIX OR SOLUTION EXPEDITIOUSLY! YOUR ASSISTANCE WILL BE HIGHLY APPRECIATED!
