Just wanted to throw this out there and thank Samsung for their awesome devices.
I recently lost my s9 ... it fell off the roof of a car when I forgot that I left it there. A friend gave me his Note 4 that had a bad battery. I spent like $15 on new battery on market place and was pretty surprised by the phones performance and features. I had a s5 and this Note 4 outperformed it by far. It may not be quite as fast as the s9 but definitely faster then any if the other cheap phones I played with. Just my $0.02
