I have a note 4 and since the update it's been painfully laggy. When I text it will freeze and then text everything I had texted several times. I can not type another text while one is sending (this is probably the most frustrating problem given my next issue) and it will always say a text is sending even after it has been recieved. Is there anything I can do short of a factory reset? I hate having to redo everything on my phone. I was hoping after a few weeks they would have fixed these issues since they were issues that were immediately obvious after the update rolled out. TIA!!!.
