I got a Droid Razr HD as a replacement and the launcher is laggy and i get multiple audio dropouts during most songs when playing music on Poweramp. I didn't have this problem with the GS3 i sent back. I tried Nova Launcher and still have lag. i turned off scheduled Backup Manager. none of that helped. I even turned off the Smart function deal. Is there anything i can do? I believe i'm on Jelly bean. i checked for updates and it says I'm up to date. The dropouts is very annoying and unacceptable. It even happens just reading a discussion forum or webpage. or doing nothing.
