I held off on updating because some of my friends reported issues with the new update. I reluctantly upgraded it because I liked some of the features and wanted to try them out - HUGE MISTAKE! I have a Note 3 and my phone seems like its barely operating. My WiFi connection is horrible. The battery life PLUMMETS. I used to be able to keep a charge all day, and now I have to keep it plugged in constantly because the battery dies so fast. As I'm typing this I took it off the charger maybe 30-45 minutes ago and its already in low 70% range. The phone lags up so bad! Seemingly more so with some apps than others. Like video players in YouTube, Facebook, the browser, etc. lag. Facebook itself and the messenger have huge lag issues too. Snapchat barely works. I've had some issues with PDFs and Powerpoints as well loading. This is bad because I'm on spring break and I have to keep up with my schoolwork and my internship assignments. I waited too long to get a note 4, and have decided to just patiently wait for the Note 5. But this update makes me want to throw my Note 3 in the garbage. I don't know why I'm having so many issues with my phone, but its really frustrating.
