What is this blinking picture of an eye that shows up when I read my email?
Is someone spying on me?
I guess it's something to do with the S4's eye-tracking software that is supposed to 'automatically' scroll as you read. My missus had a demo and claims this only works if you move your entire head, but she's an Apple-ite so is somewhat biased
I think you're right, I thought of that about two minutes after I posted this, and when I disabled smart scroll, it stopped.
Also, please explain to the missus that Android is the best thing out there.
We can't have misconceptions about it floating around.
No, it's the NSA.
The little icon means PRISM has been activated and they are watching your every move.
You should post that over at macrumors.com - that'll get them fired up
The eye icon appears in blue to tell you that the Smart Scroll function is enabled and the system is attempting to "track" with your face to begin smart scroll.
Once the system lines up with your face and is ready to work, the icon will turn green and the eye will have "eyelashes" to let you know its active.
Then you lower or raise your head to scroll through the email.
Too bad the eye tracking gimmick thing doesn't work w/ non-stock apps, like Dolphin and Firefox browsers, etc.
Smart Scroll is a fair bit gimmicky. I can get it to work with just my eyes only holding the phone at eye level and in good light, but who holds their phone like that? It does also track the nodding of my head - I look like I'm agreeing a lot on a video call!
Toggle it on and off from notification drawer>extra toggles (top right corner) and the Smart Scroll toggle.
Its eye scroll you can turn it off if you want in settings.
SmartScroll actually works very well... too well for me. I tend to speed read and scan pages and it would track my eye movements and flip the pages up and down. I'm sure you could train yourself and get used to it but it's still pretty cool.
I don't think it's so much the eyes that it tracks (even though it's called eye tracking) so much the face itself. I have to move my head up/down, not just my eyes, to have the screen scroll correspondingly.
