[Q] S3 Touch Sensitivity - Galaxy S III Q&A, Help & Troubleshooting

I've a problem with an s3 where the screen appears to be either too sensitive or not sensitive enough, or just not holding onto the motion of touch. If I go to the system test by dialing *#0*# and doing a touch test you will see gaps appearing in the touch line as attached in photo. I've another s3 showing a continuous line. Is there a way to adjust this motion (in root or not) to cure this?
Driving the the phone user nuts as its becomes a nightmare in web sites and dragging icons around!

The touch on the s3 is amazing, because this is the first phone with a special touch chip inside... i can post links if anyone want, but to lazy atm to search...
I think your unit is a bad prosuction or sth...
Change it...

+1 bad hardware.

Your lucky bro, if they where red dots missing, you'd bricked it

[Q] Touch input problem. Not Detecting very small movements.

Ok I noticed this little issue with the touch screen.
Maybe this is how it is meant to work but just wondering if its the same for everyone.
Basically when you first touch the screen and then move your finger in tiny movements back and forward like 2-3 pixels distance the screen just recognises your initial place you touched. It doesnt recognise the little movements. You have to make a bigger movement with your finger and then the screen starts recognising these tiny movements.
Its like its been set up with software to only track your finger if it moves a minimum distance. If this distance is not met then keep the original place where the screen was touched.
Best way to see this is get a multitouch test app from the market. Basically just one that gives you a dot under your finger when you touch the screen.
Touch the screen and move your finger in tiny movements back and forward. Like really tiny (2-3 pixels in distance)
Does the dot move or does it stay there like its stuck ?
Then you have to make a bigger movement with your finder before the dot starts moving. But after that you can do those tiny movements you did before and the dot moves.
Hope someone understands what i'm saying.
My old phone didnt do that.
Someone try this please
What about touch screen settings are their any ??

Same result for me, very small movements of the finger are not registred...
I think the touch screen driver needs work or calibration, see other posts regarding screen sensitivity, screen doesnt pickup light touches sometimes, sometimes I have to make a defined press on the screen for it to work. I have decided I dont mind this now as it is less likely to pickup accidental presses but I still think it is a little under sensitive.
The thing is if you make a big movement and then with your finger still held on the screen make little small movements it recognises them. Its only when you first touch the screen it doesnt recognise the small movements.
Its like its been set up with software to only track your finger if it moves a minimum distance. If this distance is not met then keep the original place where the screen was touched.
Maybe for typing etc so you dont accidently hit another key.
Anyone else able to confirm ? See if it detects tiny movements when you first touch the screen, and then move your finger around for a bit and then try tiny movements it should work then

Yup, definitely not a bug IMHO - just tried while playing angry birds and it nails it to the half pixel - there's nothing wrong with the hardware. I find the lack of registration of small touches a major plus, I suppose they should add a menu to disable it for those who don't like it

I know exactly what you're talking about.
Here is a test for all of you, go onto a webpage, view it at it's native resolution, which will be bigger than your screen res.
1) Drag the screen at 180 angle directly horizontally, say to the right do this slowly and move the screen a bit.
2) Now try scrolling the screen upwards or downward, slowly and carefully without taking your finger off the screen.
3) you should find that the screen is now not responding to your careful touch to scroll in a different direction you originally was scrolling.
4) given that you seem to be locked into scrolling left or right only, drag fast and long distance either upwards or downwards (or diagonally)
5) hey presto, you can now scroll in any direction again with movements as small as you like
Its weird on angry birds, it detects these really small movements.
But on Nova HD for dragging the camera it doesnt detect these really small movements.
However if you make a big movement it then will detect the really small movements as long as you don't take your finger off the screen or you have to start over again.
Another way to see this, is on the lock screen.
Touch the lock image wait a few seconds then move your finger like 2 pixels left and right (really small amount).
The lock image won't move at all. However if you then make a big movement so the lock image starts moving (and keeping your finger still on the screen) then move your finger 2 pixels left and right it moves.
Touch the image and wait a few seconds , then move your finger
Seems like its something to do with software. Not sure how angry birds manages to avoid it.
I reckon it can be patched so it doesnt act like this. I wouldnt have a clue how to do it tho. Someone might tho
Anyone tried it on the lock screen? Same thing ?

Yep thats it there ^^^ . Thanks.
Hopefully it can be modded. Looks like samsung added a minimum threshold
Yeah I hope so too... looks very annoying.

[Q] cant capture screen shot with the palm method on sgs3

hi i have selected the option to take a screen shot from my settings by swiping my palm but it wont capture a screen shot does any one know what i am doing wrong or can help me?
It takes a bit of practice and doesn't always work for me.
Put your palm perpendicular to the screen with your pinkie touching the edge of the left wide side of the screen and slowly slide your hand across. Try it a few times and it'll probably work. If not there's always home + power.

Hi,
it took me also some time to get it. But you have to slightly touch the screen and then go from one side to the other.
Here is a short description and 2 videos of both methods (palm and home/power button):

it dose not want to work for no reason bro.
If you really need to get it done and got adb on your computer you can use this command: /sbin/screenshot /sdcard/pictures/sgs3screenshot.png
Its more of a karate chop, right to left than a palm
It works well for me. Make sure it is enabled in your settings first of all.
The way it works is not by touching the edges of the screen when swiping, it's just by swiping your palm on the screen. It will detect a large mass moving across the screen and capture the image.
Make sure you swipe horizontally in accordance with the device's orientation.

odd issue with the keyboard on S2

I have a galaxy s2 running ICS (but the issue occurred) and I have a very odd issue with the keyboard that I am hoping someone could help me with. I have searched around but did not find anything already posted.
A short while ago, my screen broke and I had it replaced, good as new. Well almost. When ever I use the messaging app, or another type of app like that (Whats App for example), when you are composing a new message, and the textbox is shrunk down to one line at the bottom of the screen, there appears to be no input detected on that part of the screen, the send button (on the right hand side) works, and the other controls all work fine, just not the textbox.
So I figured that when the screen broke, it messed up that part of the screen, but other apps that have controls in that region (such as the camera app that has the photo button, or the lock screen with the emergency call button) all work 100%.
Its just textboxes at the bottom of the screen that do not seem to accept touch events. VERY odd.
Has anyone seen this before or know of a few tests/checks I can do. I am a new-ish user to Android.

This really sounds anoying but i know several issues quiet close to yours.
For instance sometimes on my sgs+ one side of the screen....in many cases the top side does not recognize any touching by me...
after loocking and afterwards aunlocking the phone everythings allright again...
i would suggest you to try to install a thirdparty keyboard from the play store.
if this doenstn work.....well maybee try another rom but i would send it to samsung to get a new phone...cus errors caused by wrong placed hardware are always comming back
fare well my friend

[Q] screen turns off when touching sensor next to front camera

hi all
i have spent almost 2 days for an answer , no luck
my problem is
my phone s3 lte . screen turns of as soon as i obstruct the front camera and the 2 sensors area . it was ok before , since few days it started doing this . now i cant take screen shot pictures by moving my palm across the screen for example , not sure what this is due to
any help please .?
You've posted in the wrong section, questions go in q&a section -those for the i9305 stand more chance of a reply that won't brick your phone in the special q&a for LTE phones.
Report your own post and ask for it to be moved.
Having said all that, you've probably got a corrupt framework or a hardware fault. Flash a fresh official stock rom after a factory reset to test. If it's still the same then send for repair.
Is this when in a call sorry to ask noob question just curious if your covering the proximity sensor

Screen Blanks out on Galaxy tab
I ran this test and your screen is only supposed to change color from white to green during the test. My screen blanks out completely during the test.
Not sure if the sensor is bad or if it is a software or and OS issue yet.
you tube.c om /watch?v=N8G6ksaciho
Need advice.
I just received a SM-T705Y, KitKat. When I am in only some applications not all, the screen shuts completely off when my finger passes over the two sensors/camera near the word "SAMSUNG" at the top of the device. I have tested the cause and done it repeatedly by putting a small piece of black electrical tape on the sensor.
With the tape on the sensor, the screen never shuts off. The screen then will come back on several seconds after I remove my finger/tape from the sensor. Also, I do not have to actually touch the sensor to get the screen to turn off. But it activates the lock screen when it does turn off. ANNOYING !!!
My SM-T705Y is not rooted. It is in developer mode.
I think its the sensor that turns the screen off when you take a phone call is still stuck on ???
I have the phone proximity sensor turned off in: Settings> When I'm the phone screen The screen stays on.
Auto adjust screen tone : ON
Auto brightness is off
I have the "Smart Stay" turned off in: Settings>Device>Display.
Screen timeout set to 10 minutes. Screen mode set to "AMOLED Cinema"
I have restarted, not rebooted the SM-T705Y

The proximity sensor is located there. That's why you have that issue. It's normal behaviour.
If you are trying to turn the screen off during calls there is an option to do so in either calls settings or display settings.
If you move the phone away from your head it will turn the screen on. It's a proximity sensor, thats its job!.
Beamed in by telepathy.
Fix
I have same problem with my samsung and I fix it!
Just close all recently used app (press button next to menu button and close all) and you will have normal screen..... Looks like some app, especially call app make problem and activating proximity sensor. So one more time close all recently used app, press button next to menu button and close all app....
Good Luck!

[Q] Touch Screen Issues Gionee P6

Hi, recently I started facing touch screen issues.
My touch sensitive buttons aren't responding and sometimes the lower part of the touch screen is unresponsive. That is fixed with a gentle squeeze and a lock and unlock. Sometimes the touch behaves as if I'm using two fingers than one (scaling when trying to fast forward video using one finger )
Sometimes the entire touch screen goes unresponsive which is fixed with a lock and unlock. The scroll becomes dead slow too sometimes. Again the fix is the same.
I'm not sure if this is a firmware issue or hardware issue. The rest of the touch works fine.
I'm using a Gionee P6
I tried to trouble shoot using the secret star codes but unfortunately the menu is in Chinese for this device.
If someone could help before I send it in for repair which will take a long time I'd appreciate it
EDIT : I Was able to use the touch screen testing from the diagnosis hardware menu and there are no dead points. Every part of the touch screen responds. Except when I actually use them in Android
