I still have the Note 4. It is two years old and has been working fine until the latest update to N910VVRS2CPL1. I updated on January 5th and since then my battery drains super fast and my phone gets really hot. I am also having tons of lag issues on many of the apps that I use. When typing a text message the phone can't keep up and will repeat words while texting. Very frustrated. Can someone help me?
