Hello everyone. I have a galaxy s9 and yesterday the phone restarted on it's own. When it rebooted it was showing a black screen and the words "optimizing apps ___ through 422" was on the bottom....it went through from 0 to 422 and then restarted again at the end. Not sure why this happened and also why it said I have 422 apps.....but the issue at hand is ever since then...I can only turn my volume up half way. I turned off the volume limiter......moved it all the way up......checked all volume settings etc etc....and even still....I can only put my volume up halfway now. This is very annoying ...anyone ever experience this?
