All of a sudden yesterday my note 4 became randomly unresponsive. Loading apps are slow, cant get phone off screen saver, or cant get screen saver to even show so I can put in password. I received a software update on 4/18 to latest version but there were no issues until yesterday. I havent loaded any new apps or anything either. I suppose its possible that a previously installed app updated..but not sure.
How can I check if an exsting app update is causing this problem, or if its something related to the new IOS version I got on the 18th?
