I got FOTA update yesterday from Oreo to Pie. After updating, I noticed that the speaker sound quality has degraded. The output from speaker is distorted/cracked. I tried playing audio from different players, tried tweaking the audio wizard settings, nothing works. Secondly, as many users are complaining about the auto brightness issue, I too am facing the same. It is too bright than it is supposed to be. Please look into this issues. Thanks.

Hi All, Good day. Could you update the system to the latest WW-90.11.162.45 for a check? Thank you. Wish you a nice day.
