Update: I might advise reconsidering updating. Many users have reported issues with it and regretted updating. Here are the list of problems:
As per user forums, this is what I've heard
• Image rotation option in the stock gallery app is gone
• Fast charging is gone or doesn't work
• Freezing or lagging
• Worse connectivity, lower amount of bars especially on T-Mobile
• No improvements in battery life
• Weird Bluetooth issues when you connect or disconnect from WiFi
