Touchscreen sensitivity

Does it seem to anyone else that the screen on this phone doesn't always register input as consistently or quickly as it should?
Is this a software or hardware issue?

I'm wondering the same thing. For instance the keyboard seems to have trouble with registering a keypress on the same key that just worked fine the press before. Granted I just got the phone yesterday and I'm in my learning curve, and it's still stock. Lovin my ns4g with no bloat either way ;-)

I just posted about this. Didn't seem as bad until I rooted the phone, but that was within about three hours of getting it. It's annoying as hell, right? My thread is in the General Forum. ugh.

The screen is definitely not as sensitive as HTC screens. And I agree, it's annoying.

My screen was to sensitive before update but saying HTC has more sensitivity touch screens I beg to differ

Mine is so sensitive that I don't even have to touch the screen, it will register a touch if I hover just above it.

what update is this you're referring to?
mine also does the hover thing. I'm getting very annoyed with this...

I know the feeling, mine seems to be solely limited to the pre-call dialer. On the dialer it works like a 15 year old palm pilot. Everything else is hyper sensitive. It works fine when in a call.

Is there a setting to change the touchscreen sensitivity on the Nexus S?

I have noticed when the screen is hot it doesn't register keys pressed, I always end up hitting the "." Its quite annoying but j do however love the phone

Is there somewhere on the phone to set the sensitivity?

Mine falls into the "So sensative that it registers a touch when I hover my finger over it".

I apologize if I'm a little cranky but no one seems to see my question. Is there ANY SETTING available for the sensitivity of the touchscreen?

No setting that i know of. I believe some kernels adjust sensitivity but its one setting built in not adjustable. I am running netatchy kernel and responsiveness is amazing.

Yep that is true, sometimes it depends of the ROM or Kernel you have.

Hello, fellow Nexus S owners. I am resurrecting the thread because I found myself in a similar situation.
But first some history and details - I own a I9023 handset and have been using stock ROM since it came out (JZO54K). Couple of days ago I noticed that the lower part of the screen (the line right above the hardware buttons) is less responsive and sometimes even unresponsive. This makes it really annoying when trying to call somebody and nothing happens when I try to launch the dialer. The same behavior is observed throughout the whole row this includes even applications button. When texting the same things happens.
At first I thought that this could be due to me installing a "Temple Run" kind of game, but I wiped it, rebooted and the problem remains.
What do you think? Could this be a hardware problem or software one?

Your digitizer might be dying.
It's also known that while charging the phone with the wrong charger the screen goes crazy, but then, unplugging the phone will usually solve the issue.

Luckily the device is still under warranty so I will take it to my vendor for repair. Maybe then I will have some info on what's happening.

I had a similar problem a while back when my battery started to die. I've never experienced any touch screen wackiness caused by third-party chargers, but this seemed to be a comparable issue albeit in the opposite direction. So in addition to my battery losing charge real quick touches wouldn't register in the bottom half of the screen.

[Q] Touch Screen Response Issue

Im running Glorious Overdose V2 but I had this issue with other roms as well for some reason my touchscreen sometimes doesnt respond. In order for it to start working again I have to lock and unlock my phone sometimes it happens frequently and other times it doesnt. Any tips on how to fix this issue?

Sorry no tips on how to fix, but I'm running stock and it happens to me too. I though it might have to do with my crappy screen protector or me somehow messing with the optical trackball, but it seems not since you're experiencing the same issue.

I have this issue, too...
...can confirm it happens on stock and custom roms.

Nope
I tried the app and it didn't help at all and sometimes my phone also starts randomly selecting as if I touched it.

Its a hardware problem. Samsung claims its a software problem but I doubt it. It happens to me all the time and I've posted threads about it as well.
What I have found is that any sweat or liquid on your fingers that gets left behind on the screen causes it to act sporadically. All you can do is constantly clean your screen when the phone is locked.

i have this problem, but i have noticed its only after iv gotten my hands wet. i kinda figured it was 1$ screen protector.

My screen would do the same thing until i bought one of the sk screen protectors. Haven't had that problem since.

Spots on black screen?

When ever my screen goes black in been opening apps or websites, I notice that there are lighter spots or smears, but they only show up on the black screen. Does anybody else have this, and or know what it is? besides on black screens, it really doesn't affect anything, but I worry it might get worse

Do a search for "blobs"
There are quite a few posts on it. Some phones are worse than others. Both of our skyrockets have small identical blobs

The lines are driving me insane as well. The blobs are noticeable in clockwork mod in the dark. I see like a bunch of black dots on my screen everywhere.... Damn.. is Samsung planning on fixing this issue for our phones?

They say they are "looking into it."

I only ever see the blobs on otherwise black screens if my eyes are very dark-adjusted. One example is if the phone is off and charging, and I wake it up (but don't turn it on) in the middle of the night.
That is: the blobs are the next best thing to a non-issue for me. The lines are a minor annoyance that I can ignore easily enough under almost all circumstance.
Both exist though, and don't let anyone tell you otherwise. A little disappointing to be sure.

I've found that the best way to evaluate your phone for blobs is to take your phone, set it to the lowest brightness setting, use the Gallery to display the color #101010 on it, put the phone in a dark room, then use a DSLR camera on the no-flash setting to take a picture of it. You need to have NO light at all coming from anywhere else, so a closet or internal room with a counter works best. It'll take about 10 seconds to capture, during which the phone and the camera need to be perfectly still.
Ignore the green tint - it's a side-effect of the overexposure.
My results:
Phone 1: My mother's Skyrocket, purchased about a year ago.
Phone 2: My Skyrocket, purchased about 6mos ago. I gave the link for this image to an AT&T Rep in the Warranty dep't, and got an RMA ready within 10 minutes.

Screen gets dead spots

Anyone had dead spots on their HOS?
On two different occasions, the screen stops working directly above the Homebutton and a reboot solves the problem..
But since it happened 2 time now, is my digitizer damaged or something?

Similar problem
I seem to have a similar problem where I get random dead spots on the screen. The problem happens more frequently with me with AOSP ROMs. Also, turning the screen on and off usually fixes it for me. I may have a bad digitizer, I'm not sure though.

I've had the same issue couple of times a while back.
edit
can't remember, but it might've been while using cm10 (only had it on for a few days).

Try downloading dead pixel fix from market it is really good fixing dead pixel
Download run the app and leave or phone for at least 6 hour with app running at maximum brightness

Sorry, I didn't mean dead pixels, I meant the touch gets dead..something with the digitizer...

Dude I had a post about this before like i have to turn my screen off a lot cause it won't register my space bars during a text or the letter t and its really annoying but turning the screen off and on fixes it

I been having a similar issue usually made the center of the screen around the t y u Button's on the keyboard.
Started roughly after running cm10 might be a coincidence though

Try wiping off the screen and turning the phone off and on.
The first might help if it's a humidity issue, the 2nd might help if it's a grounding or static issue.

I don't have these issues but is it related to this? http://forum.xda-developers.com/showthread.php?t=1679649
Touch Button Issue HTC One S

It's pretty much the opposite of that issue to the point where il be trying to get in the menu and my touch on the menu key doesn't do anything till I turn my screen off and on cause the bottom part of the screen is unresponsive... And I'm on stock no root

This!! I always have to do this once in awhile.

This only happens in aosp roms (dont know yed on aokp). It used to happen to me sometimes on cm10 but now I´ve been for a while on sense roms and didn´t happen anytime.

i agree with the above, ive only had this issue on cm10

I run into the same problem sometimes. It's most noticeable when using the keyboard but I've had it happen on another part of the screen. Like others have said turning off the screen then turning it back on always worked to fix it.

I was having this issue in CM9... Once I reverted back to Trickdroid 7.1, this issue no longer happens. So it sounds to me like it's related to the driver in CM9... I suspect that if I switch to CM10, the issue will still be there.

mad screen

hey guys soory for creating this but I really wanted to discuss I guess we all have this problem from day 2 of our pico example ya were simple. browsing opera doin nothin much suddenly ya observe that screen starts to zoom in zoom out and even clicks at certain place repeatedly again and again the place is at top right of screen generally why it happen it gets solved by locking and unlocking screen

it's not about cleaning the screen.
Something internal is causing it.

No, its because sometimes there is dirt and oil accumulated on the screen as they may be charged substances they conflict with the capacitive touch screen as the capacitive screen senses a finger wherever there is that charge so cleaning the screen fixes it !

No it's not the case you are saying about. It happens to me also and only when my net connection is on.
Removing dust particles/cleaning doesn't help.
And exactly the point of wildness is in the top right side.
