So I just got the S5 on Monday and have been playing around with it. I've never been a huge Android fan until I got the S4 and fell in love. One of my favorite and most used features was the ability to use the flashlight from the lock screen using the volume buttons. Is this possible with the S5? Also, Again I don't know enough about them to figure out the OS for the phone. I know it's the 4.4 Kit-Kat but is there away to go back to the 4.3 jelly Bean which I think is on my S4 without rooting or voiding the warranty? I do like most of the Kit-Kat but I really liked Jellybean and was very comfortable with it.
