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
Sent from my Nexus S using XDA App

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.

Screen flickering issue

Hey everybody...
I just got a new note & everything is excellent except that I've been noticing some weird flickering in the screen... Its not even flickering, its more like it goes dark for milliseconds & its not that frequent. Should i be conserned or its a software issue... does anyone have such an issue?

Have you got auto brightness enabled? If so try manually setting the brightness, also check your screen timeout in setting /display set it to a 1min not 15secs

Auto brightness is off. The same issue is happenning with my galaxy s3.

After some testing I found out that the screen issue is related to some apps only such as chrome & xda's app. Most other apps work just fine such as s note, photoshop, youtube, all games & the home screen shows no flickeri g whatsoever.
Sent from my SGH-T999 using xda premium

I have seen this, I was worried but it is very difficult to return my unit as it is a grey import.
I totally didn't notice that it went away after changing screen timeout to 1 minute. Battery life is good enough to easily cope with this.
Setting back to 15 seconds to see if it re-occurs.
fyi, I leave brightness auto.

I can confirm that the problem is solved. The whole issue is that some apps are conflicting with the hover function for the s pen. Once you disable that function in settings all becomes completly normal without any issues.

I have the similar issue on my Note 10.1 - the browser is the biggest 'flasher' and it seems random. I called Samsung support - They had me reset to factory and the issue went away, but eventually came back. I don't want to have to keep resetting to factory as that is painful for me to reconfig everything and I tend to believe that if I restore to ClockWorkMod backup, the issue will still be there.

Hi.
l had the same problem earlier. Simply deactivate the hovering S - Pen icon, and voila!

Apps reopening themselves?

Ive noticed recently that my browser and youtube apps seem to minimize and then open again. I dont see the homescreen, the app kinda shrinks like it was closed, and then expands from the top. Im really not sure what has caused this. This only started happening recently and i have no idea what could be causing it. The only thing ive installed recently was the humble bundle games.
When it reopens, it remembers what i was typing in the youtube comment, but the video is stopped and i usually need to rewatch the ad before i can skip back to the video position. Really annoying on the bigger videos.
Other problems im having is i get random lines flicker across the screen, and almost looks like its an 'extra' line that shifts the image up by one pixel to make room for it.
And then i noticed on the asus keyboard there is a spot on the spacebar that doesnt work. It makes the typing sound when clicked, but no space character is typed. Its on the far right side of the spacebar. It was extremely frustrating until i discovered why half the things i typed had no space even though i was SURE i hit the spacebar.

I'm having the same issue, I posted a thread about it over in the Q&A section, but still haven't heard of any workarounds... but i will at the least confirm i have the same issues

I can also confirm I am having the same issues, all of them.
Especially prevalent is the apps minimizing then opening themselves up again. I've been trying to figure out if an app is doing it but I don't think this is the case. I have also installed Humble Bundle apps though, it could potentially be that.
The keyboard's spacebar seems to just be bad hardware design. I miss a lot of spaces as well and have slowly migrated my thumb to the center of the spacebar because of it.

It was happening to me with the old firmware before i installed .18 even. I held off on updating until yesterday. Its got to be an app...

I think I fixed this issue by enabling GPU rendering in developer settings... Now the only issue is the random black line flickering which seems to be a common issue for everyone on Android 4.1.1
Sent from my ASUS Transformer Pad TF700T using XDA Premium HD app

The apps re-opening issue has vanished for me, likely due to an app update im guessing. I didnt change anything except update some apps, though im not sure which one it could have been.
I still have the lines flickering, and the right end of the space bar on the virtual keyboard still doesnt work. Etc. Though, these problems seem more common so im guessing/hoping they will get fixed.

Yea I haven't seen it either.

Smearing is not just in pure black background

I found smearing also happens not only in pure black background.
For example in this thread:
http://forum.xda-developers.com/showthread.php?t=2327389
The first post of the thread smears if I read with xda app using "xda free" display style (dark theme) setting. The first post has dark blue text in dark grey background.
I tried to capture a video but the phenomena cannot be seen in video.

Still, there are people here who keep on repeating smearing is fixed.
It's not and won't be due to its hardware nature. /working theory /
"Congratulations" to all the reviewers who missed such an easily to notice problem. I noticed it 5 minutes after launching this phone for the first time...

Might sound silly, I have tried to replicate this issue on my s4, I honestly cannot see the problem. Am I the only one? Normally I am the first to notice things like this, making me think that the issue is either sporadic or that samsung changed something in more recent units, (mine is about 3 weeks old)

Sent from my GT-I9505 using XDA Premium HD app

Make a paint document and fill it with pure black. Then delete a white space in the middle. Open it from the phone and move the white dot around. If you get no smearing then - you have a normal phone and we have deffective units, which is not nice, but can be repared; or your brightness is very high. Lower brightness exaggerates the problem.
However, since MEA Samsung changed Settings' background to grey from black, which for me is a sign that they know about it and that's a hardware limitation. Pixels "lag", because it's the first time since Galaxy S that black actually is "turned off".

It's worse with grey on black than it is with white on black and also it gets worse the lower you have the screen brightness. grey on black at minimum brightness is an absolute mess on my phone. But i should stress you dont really see the problem in normal usage at all.

Hi, on firmware mdm so not the newest. I'll do further testing tomorrow
Sent from my GT-I9505 using XDA Premium HD app

The darker the screen is, the more noticeable the smearing becomes.Touchwiz menus were black and now are grey, thats how samsung thought of to fix this but in certain apps with real black background it all comes alive again so i think this is a hardware issue as many agree also and its a bit of a let down to Samsung Quality Standards when we pay so much for a flaship device like this. Definitely there is room for improvment with this amoled screens.

I have not noticed any screen smearing till now.

Right, I have tested using the white dot in the middle of a true black image.
I can confirm the issue does occur, but only when the screen is set to or just above minimum and not to the extent I see it as a problem, I still cannot seem to replicate the issue on settings window even at minimum brightness.
For me, this is a none issue however If the issue is more prominent on some screens I can understand how it would be annoying.

I may be one of the few to not actually give a rat's ass. I didn't care about it when the settings window was truly black and I don't care now when it's LCD-ish black (greyish-black).

with high brightness you will not notice the smearing problem. With low brightness is when you can notice it

Just try to read articles in Pocket app or in feedly using black themes.
I switched to ligtht/white themes killing battery life but avoiding smearing. Now my device lasts 3h screen time at best. F... great.
Amoled screen that's not really compatible with true black! The most advertised benefit of amoled is gone with this flawed screen.
What a shame.

Are you 100% sure about that? If that's really the case, it's probably some feature in the kernel that actually turns off pixels completely.

[Q] Nexus 5 Touch Lag 200ms?

I've been using my Galaxy Nexus for the last two years. I have never really noticed any kind of "touch lag" during this time.
I just purchased a Nexus 5, rooted, installed TWRP 2.6.3.4 and also flashed the Dec.12 2013 version of Cataclysm
I recently noticed after about 2 days of use that:
Typing in general is normal, the keyboard reacts to my touch instantaneously
Games, or any other usage of the touchscreen seems to have about a 200ms touch lag. Whereas the Galaxy Nexus never had this issue.
Asphalt 8 is not playable due to this, the calculator app lags like crazy, or even just hitting the menu button.
Note: I noticed asphalt 8 was not playable before I did any rooting or flashing - however at that time I couldn't figure out the reason.
Is anyone else having this issue? Is there anything I can do to fix this?
I found that increasing the pointer speed may have helped a little. I disabled the vibration and sound on touch as well, that may have helped, but it still feels slow in calculator...
edit: Ok maybe I'm exaggerating a bit. It may not be 200ms but more like more like 70ms

I'm just guessing roundabout, really. It's not like I timed it or anything.
I thought it was frustrating because I couldn't play even play CopyCat (the game where you copy the colors it beeps) without holding each color for a half second before continuing to the next due to the lag.
I found that increasing the pointer speed may have helped a little. I disabled the vibration and sound on touch as well, that may have helped, but it still feels slow in calculator...
do you have any tips for improving it?
edit: I guess the reason I'm complaining is because the lag is near zero when typing on the keyboard. How is it that there is no lag when using the keyboard, but then the lag is present elsewhere?

Ok, so I went ahead and did a nandroid restore. I'm still getting the same thing.
Comparing the older Galaxy Nexus and the Nexus 5 on the same Copycat app, just a quick tap on each color using the Galaxy Nexus is enough to see a color illuminate and make the sound. On the Nexus 5, a quick tap renders no illumination or sound, though the game does see it as being pressed.
Yet on both devices, the keyboard response seems to be equal.
