Please tell me how to uninstall a software update on galaxy note 9. This is suppose to be the newest phone but with the update I received today, 02/07/2019, it has made it look outdated! The system apps look stupid and my home buttons also look stupid and doesn't have the option of clicking twice for full view of the screen. I now have three obnoxious lines at the bottom of my screen. Send help! Officially annoyed with the phone I've only had for 3 weeks.
