Well I recently left Samsung for the iPhone 6 Plus but I'm tempted to get the Galaxy S6. I just have a few questions on if some of the things I left for have been fixed. One thing which isn't really a Samsung thing but an android thing is the YouTube app only playing in 720p. I never understood buying a phone with a quad hd screen with nothing to really experience it fully, I would even settle for 1080p viewing, I used to have the Note 4. Also does the netflix app play in quad hd or 1080p. Also how is the battery life, I currently can get through a full day? I'm really looking at the S6 because I made the mistake of buying the 16 gb IPhone 6 plus and I'm constantly having to delete stuff but instead of just buying a iPhone with more memory I rather give Android one more shot. So please guys help me out.
