Is there a manual for the S4? If so, where can I find it?
Go to this link and scroll down a bit; there's a link to download a copy:
Samsung Galaxy S4 16GB Black Mist Support | Verizon Wireless
There's also a generic Samsung S4 manual here: http://downloadcenter.samsung.com/content/UM/201304/20130415110443294/GT-I9500_UM_EU_Jellybean_Eng_Rev.1.0_130412.pdf.
For good measure, this is a direct link to the Verizon manual: http://cache.vzw.com/multimedia/mim/sam_galaxy_s4/samsung_galaxy_s_4_um.pdf.
