Many issues are occurring such as
-audio not working
-mic not working
-SD card not being recognized
-200/400 mhz bug
-docking issues
-reverting the update deleting SD card files from some posts I’ve seen
-some games performing worse or some not working at all
Probably recommend just holding off on this update and wait an update or two. I understand this update comes with the SMT fix and Color Saturation and better gpu performance but these bugs are pretty big negatives.
I checked everything and saw nothing. I tried it docked, undocked, turned WiFi and Bluetooth off. Then I believe I was getting the 200/400 bug. I was getting like 9-10FPS. I rolled back to previous OS and everything is working great again.
Are you ABSOLUTELY POSITIVE storage trim wasn’t running? Reverting back to the old OS would likely stop it from running temporarily
