Sorry to see you are still having problems. Try clearing the cache from your phone then turn the phone off and pull the battery for a few minutes then try it again to see what happens. You can usually find the option to clear the cache under Storage in your settings menu ( not 100% sure where the option is on an LG device but there are apps in the playstore that will do it too or you could manually go through every app and clear the cache from the application manager. ) As a last resort I would maybe try a Factory reset but you will lose all of your data including wifi passwords, homescreen settings , contacts , etc. If you do end up try a factory reset be sure to back up all of your data first .
