Hi guys, I just got a brand new S4 from Rogers and while playing around with the phone I noticed some of the features weren't working properly. One of them was the palm gestures settings. I tried some many times to get the Screen shot and Play/Pause features to work but it failed. And another problem that I encountered was the gyroscope sensor. As you can see in the screenshot, the ball doesn't move at all even when the phone is standing up. So do I have a defective S4?

That screen is supposed to "calibrate" the gyroscope so it make sense that it doesn't move. You are essentially teaching it where perfectly centered is. In order to do that, you have to lay it on a surface that is perfectly centered. If you lay it on a surface that is not perfectly centered and press it, it will be off. I haven't messed with mine yet, but it seems that is the way it would be.

That's weird because on my S1 the ball moves around. But what about the palm features? Do they work for you?

Screen shot does. Not sure of the others
All work for me. Just have to get used to how to use the gesture. That calibrate screen doesn't move, it's only meant for Calibrating

Hey All,
I was reading the user manual for the S4 (Link), and it said on page 8 "Do not use a screen protector. This causes sensor malfunctions".
If I didn't look online for the manual, I wouldn't have known this information, as I didn't get the manual with my phone. (Only the quick start guides).
What is everyone opinion on this?

I don't think the sensor will be affected if the screen protectors are well cut at the right areas.

Which areas?
They probably be cut around sensors at the top.

I'd assume that it's because of the floating touch. Being an owner of the Note 2 (that has floating touch with the S-Pen) I can tell you that a screen protector doesn't affect my experience.
Now if the S4 uses a different way of capturing floating touch (because it doesn't have a stylus), this may be true. I suppose only time and testing will tell.

Get a screen protector and a case if you don't want to scratch your phone, that way you can sell it in an "excellent" condition. I had my GS3 for 8 months and it's still in pristine condition.
I have had a screen protector on since day one with no malfunctions. Also, you will notice that protectors designed for the S4 don't cover the sensors at the top of the phone.
Sent from my GT-I9505 using xda app-developers app
It makes the floating touch slightly less sensitive (and accurate at longer distances), but other than that it's fine.
I have a screen protector on my s4 and have no issues
I also used screen protector from day 1, no problem.
had one no change btw after accident not ahve one now btw think may nto go to bu one what do u think? buy one:?!

I read somewhere that it was indeed the sensor at the top, mixed with the old technology too.
The apps I know it works with are stock email, stock texts and flipboard. Not sure what else. It doesn't even seem to work on lockscreen...

Samsung is using a super sensitive capacitative touchscreen that can sense your finger even when its a short distance from the screen, essentially. its the same reason that there's an option so that you can use it with gloves on
Sent from my Nexus 7 using Tapatalk 4 Beta
I'm no engineer, but this is my basic understanding gleaned from reading wikipedia and other sources. Capacitive touchscreens work by sensing changes in an electrostatic field. Your finger is an electrical conductor, which distorts the field. In normal phones the field is calibrated to extend just past the surface of the touchscreen. The S4's electrostatic field is simply overcalibrated to sense your finger from a distance, and it's also why it works with gloves on.

nothing to do with the capacitive screen or proximity sensor. if the screen was THAT sensitive it'll be firing off to even the slightest atmospheric disturbance. actual workings are related to the 2 IR sensors flanking the speaker grill which individually log IR intensities emitted by ur finger in front of the screen. an algorithm then compares these values and works out where ur finger is pointing.
AFAIK it works with help of IR Sensor and/with Proximity Sensor
If screen sensitivity does this job then ...Nokia Lumia 920 to 520 all devices all should have this feature cuz all these devices have Super Sensitive screens

The air is much more inert than your finger. The proximity/IR sensors just blast IR beams away from the phone for things like Air Gestures and have nothing to do with Air View. They certainly don't shoot beams across the surface of the screen to detect your finger. The finger hovering simply uses a more sensitive capacitive touchscreen, as Sony explains here:

This happened with me also.
The air view works in stock messaging app , gallery , flipboard and even when you dial a number if you have speed dial feeded.
For this you need to hold air view option in notification bar for about 2 seconds then a set of options will open. There you can switch on air view for messaging, gallery etc etc.

It will be the electromagnetic field that the screen is detecting from your skin/finger. The same way that on other screens, they don't work with gloves unless you have the special gloves that have conductive fingertips on them.
Nothing to do with the sensors on the top of the phone cos if you cover them up, air view still works! Plus the sensors aim out the top and at 90 degrees to the phone face, how would they sense something almost touching the screen on the bottom?

Has anyone noticed that the screen on this phone is way too sensitive? Mine goes as far as to register a touch when I hold my finger a few millimeters away. This results in accidental double presses and is very frustrating especially when typing. I even made sure the high sensitivity setting was off.
When in Camera mode, it even snaps photos by itself without my finger anywhere near the shutter button.
Any tips?

As stated in OP I had made sure that the hi sensitivity option is off as well as any other convenience features.
As for the camera, I have been in windy conditions when this was occurring, so maybe it was thinking I was giving voice commands. But I had all of that turned off as well, so I'm not sure what the deal is.
I will probably revert to factory settings again before returning the phone to make sure it's not a software issue.
I think that Samsung went a little overboard with the touchscreen on this phone. I do not like the fact that everything can be used to touch the screen. What I actually liked about my iPhone 4s was that it was picky about only recognizing fingertip touches.
Great phone overall but this issue sadly ruins it for me. I do not want to go back to iOS so I think HTC One is the only other strong competitor.

I am having the same problem as you. I can type without actually touching the screen. Now that I know it isn't normal, I guess I'll swap it for a new one...
So I have this weird issue. The very bottom of my screen does not respond well! At first I thought it was a bug with the navigation bar, tried several roms and tried PIE controls until I figured that there is something wrong. I have the navbar now set at 48 dpi and I have to press at middle of it to work, where the very bottom is dead. I activated 360 rotation so that my statusbar now is at the bottom of the screen instead of navbar and it does not respond at all! Anyone can explain ?

I have Tried like lots of different roms with clean fresh installation and the problem is still there ! I think its a hardware problem. For ezample right now if I set my navbar to 32 dpi it wont respond at all because the bottom of my screen have lost the touch sensitivity. I have droppes my phone several times, could that be it ? I cant really remember when I exactly started noticing the issue...but just few days ago...I have tried PIE and same **** :s I have to set the trigger area to max for it to respond...and yes im talking about experiments after a clean install before installing ANY third party app

Think Im gonna give no damn about it and of course buy the nexus 5, which I would have done either way..but im surprised how can a touchscreen lose a part of its sensitivity somewhere on the screen ?
Sent from my Nexus 4 using xda app-developers app
If you look closely at your screen at an angle with the screen off you will be able to see the digitizer matrix that is fused to the screen.
It is a series of squares.
Each of them squares has 3 horizontal lines and one vertical.
Behind the bezel there will be the circuitry that connects every horizontal and vertical line
If say for instance after one of your phone drops it has damaged one of the connectors at the side, you will lose the entire row of touch detection. Which is probably what has happened

Alex is right i had this happen to my moto defy. I'd say get it done under warrnty no matter if youre keeping or selling. Improve your resale value and protect you from having the entire digitizer die on you
Why?
I mean... sometimes it response on two knocks and sometimes i need four or more....
Have you seen the same ?
Yep, it's pretty normal.
I assume with it being a new feature it's not properly optimized properly if thats right word for it.
If LG get their ass into gear we may see a fix for it. And I mean IF.
No, but i have noticed a trick with it. If you put your hand over the top area of the screen, and then try to knock on. It will not work no matter what until you move your hand. I believe it is a sensor.

Thanks for the double at the top of the screen hint - works great now
What's worse is accidentally switching on the screen by simply handling the phone and it recognizing your "handling" as knock ons.
Yes, the proximity sensor will keep it from working. Since i have been more aware of this it works much better. Even if i have the phone in landscape and have my thumb on the slightest edge of the screen it will not work. U dont have to be over it. Just close will keep it from working.
