I'm seeing threads that mention some failings of the S4 that match some of the failings of my S5. I thought the S4 would have been the way to go until stock was deleted and they only carried the S5.
I still have my S3, and it's still much faster and more responsive than my S5, and the microphone actually works. The screen goes out when I turn my wrist away like it should, While my S5 tends to keep the screen awake (not AOD, but wide awake like you're looking at it) indefinitely unless you catch it and jiggle your wrist. I have been caught at least once with a dead battery out of nowhere until I caught mine staying full awake after a couple minutes a few times.
When auto-unlock works, it's slower--much slower with my S5 vs the S3. Also, Siri is dead slow on my S5. It's like a core on the CPU is dead.
