I just got a new Note 4 last night... two questions: 1) I keep getting a notification with a little broom icon telling me that the phone is using too much ram, is over heating, lagging, etc, and asking me to "boost" it. What is that about. Again, this is a brand new phone with very little installed on it thus far. 2) Is there any way to get rid of the Flipboard news "Briefing" on the far left home screen?? Thanks!
