Hi Friends, I’m having an issue where at times my phone’s volume control goes haywire, and either rises all the way to max volume or lowers it to zero. Also, it’ll skip a song that’s playing or go to S Voice without any buttons being pressed or words said. it usually happens when the headphones are plugged in, or Spotify is running. However, it’s also happened without those two things. Also, I wanted to know if it’s a good idea to update to Lollipop. Thanks in advance.
