i9023 Touch screen lag/delay? - Nexus S Q&A, Help & Troubleshooting

Just got my SNS yesterday and i got an issue, donno if it happens on others nexus s tho.. by the way this is the i9023 sclcd version.
The touch screen is responsive, but there's a little delay everytime i touch the screen, so like when i use the keyboard, and i press a character, the popup magnifying thing doesn't come out immediately, instead its delayed to like 0.2 seconds after i pressed a character..
Overall its just like a little bit delay everytime i touch the screen such as swiping home screens, its delayed to like 0.1 to 0.2 seconds which looks like awkward, especially when typing with the keyboard it makes the keyboard very inaccurate to type, and uncomfortable.
Anyone having this problem? I've rooted and flashed cm7 and the problem still exists..

i also have a i9023 with the same problems, typing is a mess compared with my last phone (Xperia X10) ... i hope that it is no hardware problem

No responiveness issues here. Maybe you should try a few factory resets before sending it back.

I think its a hardware problem because i've flashed cm7 and miui the problem still exists.
Anyone else having i9023 and does not have this issue? If most people don't have the issue i will request for an exchange for a new i9023, but if this issue is common on i9023 i might just exchange for an i9020.

But i've wiped all date and cache and dalvik, do i still need to try a factory reset?

I would suggest you do, it seems to fix a variety of issues if you're lucky. Backup your data and try it.

How come whenever i try to do a factory reset it goes into clorkwork and gives me an exclamation mark with the android guy?

No responsiveness issues here either.

Alright, i think i will just go ahead and get a new replacement.

Anyone having the issue? Because i bought it off ebay, so i requested for a replacement, but the seller dude from Hong Kong, saying that if they received the phone, tested and everything is working fine, they will charge me for 10% restock charge and AUD$20 shipping fees, and i checked the Australia Post Calculator, it needs AUD$19 to ship the phone back for a replacement, so i think its not really worth it.. Since i received the phone yesterday and from the moment i turned on the phone i found this touch delay thing, so it's kinda defective, and i think they should pay the fees for me to ship the phone back for replacement.
Anyways, is there a rom that i can flash to go back to "out of the box" rom and settings so i can send it back? Thanks.

Thanks for that, is there anyone else having the touch delay issue? If you do please say so, because i am giving this post to the seller as a reference, thanks.

No delay on my i9023.

Thanks bro.
Just did a little test, in app drawer, swipe up/down hard til the end. When i swiped and released my finger, the delay before the whole app drawer moves is pretty obvious, it was like 0.3 seconds after i release my finger.
I think i should return and get a new one.

Nope. It shouln't be like that. I hadn't have any problems like this on my i9023. Or on i9020.

Take a look at 0:35 - 0:40, its almost identical on my nexus s.
It just feels sluggish.

ive got the same issue.. too much of a hassle to return the phone though

I'm also seeing this.
I've been using a nexus one for a year and last week I got a new nexus s (slcd, that is, i9023). I noticed the screen delay right away. Here's a video I just took, sorry for the out of focus thing, the camera I used has a fixed lens, but you can see the problem perfectly anyway. If you watch it frame by frame (i think you'd have to download it for that, youtube player is too simple) it is VERY clear.

The phones have exactly the same settings and apps (google backup rocks) and both are stock, GRJ22. I can assure you both my fingers tap at the same time.
I also noticed the N1 picks up much shorter touches, with the Nexus S I have to keep my fingers longer for the taps to register.

G1 dev phone screen does not respond amost 70% of time

i purchased g1 from ebay, right from day1 the screen does not respond properly in fact most of the times. i need to reset soft one to at least g1 working. i upgraded to jesusfrake adp1.1 but issue is same. looks like a s/w bug or problem as if it were a h/w problem it would not have worked at all. if iam lucky it works like a charm but stops responding once i get some sms/email alert or install any app from market. can someone help here!!
Have you already tried reflashing the firmware? If not, do that. Otherwise, why don't you contact the person you bought the phone from. It sounds like it may be a hardware problem which might be why that person was selling it.
i did flash everything from bootloader to firmware to rooting. but problem remains same...it works for 5 minutes and again screen stops responding but trackball is active....right now iam on latest JF formware..
is anyone facing a simillar problem??? any work arounds....
Sometimes my home screen goes completely blank on me and seems nonresponsive for about 30 seconds. Can be pretty annoying. It seems to happen when I'm switching from an app to the home screen.
Contact HTC directly and ask for an exchange or something. All G1's have been out for less than a year and so they should be covered by warranty.
I put a new screen protector on my G1. I noticed that it had a bad reaction with the touch and I took it off. After I took it off, my touch screen got much worse. It was very jumpy and unuseable. There was a practically invisible film on the screen (couldn't even really feel it. I took a little bit of soap on a lint free cloth and wiped the screen down and let it sit for just a minute (to soak any residue) and wiped away. My screen worked perfect after that.
I was ready to call in for a replacement.
could it be a bug as if it were a hardware problem it would prevent touch screen responding at all!!!
i downgraded to rc 30 and rooted the phone, now its working like a charm!! strange though.......

Blank screen

Hey,
So last night my Sensation was on charge when I received an email. When I tried to unlock the phone the screen didn't activate but the lights for the buttons at the bottom did. I tried a few times but was unsuccessful, though luckily a hard reset seemingly fixed the problem.
Has anyone else had this issue? I've already contacted Orange and they said they'll replace the handset.
I recorded a quick (and pretty poor quality ) video on my old BlackBerry that I might try and put up on youtube later.
probobly the launcher is loading or force closed. im not sure though, it happened to me too
Happened to me once so far
Hm, probably something that will be fixed in a future update then?... Still, might get a new handset anyway - I may see some improvements in battery at least.

Camera Not Starting or showing black

I was wondering if anyone else has experienced this problem. I am having an issue when I start the camera application it just shows the camera UI but the rest of the screen where the camera preview would be is totally black. On that screen hitting the buttons don't do anything.
If I open an application which uses the camera like Instagram it comes up with the error "Cannot connect to camera" or the screen goes totally black.
I am a bit of an Android noob but I can't figure out why this is happening. I have tried clearing the camera app's cache and force restarting it. It doesn't seem to help. The only way I can get the Camera to start working again is a reboot and then it might only work when I first boot it up. If I try again 15 minutes later it starting messing up again.
If you guys need any other info let me know, thanks for the help
return it, mine is just fine.
I tried to exchange it and all the AT&T stores are sold out
This is a pretty frustrating problem, compounded with the fact it seems I'm the only one having it.
Might be a dumb question but have you done a factory reset? Clearing cache normally will do the trick but if not, I'd go with a reset.
Well everyone, the camera problems turned out to be a symptom of a much larger problem that started happening. The LCD eventually started going rainbow whenever there was motion on the screen or I touched it. What this has to do with the camera I have no idea but I think there was something really wrong the hardware I got.
It's hard to explain what it looked like but it was like a seizure inducing flashing of white and other colors of the rainbow. Basically the LCD was failing or there was a loose connection in the hardware somewhere. I called AT&T and they were really awesome about it; they called all my local stores to find a One X for me so I could exchange it today. They even had the store set one aside for me, nice work AT&T.
When I got to the store all the employees gathered around to see my epically failing One X and everyone agreed the screen would kill a an epileptic person in short order. 10 minutes and I was out the door with my brand new HOX fresh out of the box. Overall this was not the experience I was hoping for my first few days with the phone but it was just my turn to get a dud I guess.
Couldn't be happier now that I have a fully functional phone, this thing is seriously amazing.
There are duds in every batch. Glad you were able to get it exchanged just fine

[Q] Should I use stock when I take this for repair?

For a few months my phone has had a problem where the screen will take control of itself or become unresponsive, it's not the phone being slow, because hardware keys respond perfectly. Scrubbing the screen with a Lysol wipe helps sometimes, but I'd rather just have the problem taken care of (it seems like it's caused by fingerprints on the screen, which isn't a problem on any of my friends' SKs and initially wasn't on mine either).
Anyway, when I take my SK to T-Mo, should I flash a ROM that at least looks stock for warranty purposes or will they not care?
If I do need to go to stock, how would I go about doing that? As far as I remember, I've never taken a backup in recovery and never ODIN'ed (stupid, I know), so I've no idea what to do. I can flash ROMs perfectly fine, but going back to stock is a mind-boggler for me (disabling Voodoo, etc).
Thanks
Mine always does this.
1. The optical trackpad detects the sunlight, strong indoor lights, etc, as movement and causes spurious scrolling.
2. Water on the screen or a finger just outside the boarder of the screen causes the touchscreen to get confused and either not respond or move on its own.
3. The touchscreen driver is prone to crashing. About half the times I want to answer a call or something, I need to toggle the screen off and on with the power button before it'll work.
None of this is because the hardware has broken. 1 is due to a bad design, 2 is inherent to touchscreens of this type, and 3 is just bad programming.
Ha! I have to do #3 all the time. Glad to know it's not just me. Ridiculous.
Also FYI, #1 never happens to me. I see people here curse that damn sensor all the time, but I have never had mine move randomly in sunlight, and it generally works pretty well for me as arrow-keys.
I also do #3 all the time, and have had problems with the optical trackpad in the past (I've since disabled it).
What the problem appeared to be was that my fingers are oily or something, explaining why wiping the screen excessively was useful. I passed on taking it to the T-Mobile store and instead ordered screen protectors from Amazon. No problems since I applied one.
Has anyone else encountered this, or is this a unique problem? I got through nearly a year without having this problem, so maybe something went wonky in the screen. Anyway, problem fixed

Touch screen problem

Hi guys,
i'm having an issue with my HTC u11, basically when i'm using the phone randomly the swipe down screen (when you swipe the screen down from top to bottom to get the notifications) comes down.
For example if while i am writing a message then drop down screen will come down when i'm typing, i then have to swipe up and continue and again.
it happens more or less all the time and is quite annoying.
any ideas?
its okay, issue resolved. NOVA Setting had gesture switched on. Swipe down for notification menu, this was the issue. lol
PLease close the thread.
Thanks

Well i had the same issue. Was driving me mad! Thanks for the info.
I don't use nova and I have been experiencing this same problem so now what?
Sent from my SM-G955U using XDA-Developers Legacy app
Yeah i though the Nova setting had solved it but it seems to be back again for me, although not as frequent.
I also experience the keyboard collapsing randomly too. Anyone get that?
Hi guys, thought nova got rid bit guess not. I still get the issue. Would this be a software issue or do I have a fault with my hardware?
Any tests I can do?
I reported my issues to HTC and they replied with the following :
To test the function of the touch screen please follow the below steps
1- Dial *#*#3424#*#* > the press accept.
2- From the options, mark Line drawing test > then press run.
3- Then start drawing on the screen to check if there are parts that do not respond
The screen does not have any dead or unresponsive spots tho and the test passes without any issues.
Does anyone experience the keyboard collapses also?
I might do a full reset soon to see if that helps any. If not i will be getting back in touch with HTC.
Did all this as well, and all the tests that I've ran pass just fine. I've also done a hard reset and it didn't make any difference. I do notice that after a soft reset that it takes a while for it to happen again. It's annoying as hell so I will be monitoring this thread. Whatever you find out from htc please update this thread so we can figure out what the hell is going on.

I also done the test and it was a pass.
I'm certain it's something to do with the software of htc. The UI has to have something wrong with it. Mind you it hasn't done it to me today yet and I'm nearly at the end of the day.
Has everyone got a case? Can't be case interference?

I turned off edge sense, I removed my screen protector and removed the case. It still does it when it's ready.

Exactly same issue here. Very very annoying. As a HTC fanboy I'm quite dissapointed. Phone less than 2 months old. I actually spoke to HTC today, they said they would have to book it in for a repair... Takes up-to 10 business days... I said this is not acceptable! Waiting for a email back.
I have emailed HTC back advising them that others are reporting the issue so unlikely that it's a single handset issue.
Awaiting their reply. No doubt it will be along the same lines that @dobknobby got and have to go through the 10 day repair process.
Will update when I get a reply.
I have had the same problem, and I have done the a lot of the same steps;
I tried several different screen protectors, thinking that was causing the issue. I have had no screen protector on for the last week, and yep it still happens.
Shut off edge sense, still happened.
Tested the touch screen, and everything passed.
Last night I noticed that it seemed to be related to the pressure I was putting on the screen, if I pressed down harder on the screen and slide my finger left or right or up the notification bar would come down. Did some more testing and for awhile I was able to reproduce it about 50% of the time. I rebooted the phone into safe mode (hold power button down and then press and hold the power off option for about 5 seconds it will ask if you want to reboot into safe mode). In Safe mode I could not reproduce it, Safe mode disables ALL third party apps.
WARNING: when I rebooted my phone to go back to "normal" all of my widgets and groupings were not on the screens, had to re add them.
After doing all this testing last night, I have not seen the notification come down, but like someone said it seems to get worse the longer the phone is running before reboot.
I was going to do a hard reset, today but that sounds like that may not help.
Not sure if this is software, but with the testing I did last night it seem to work fine in safe mode. However I have wondered if it is something with the screen, like is flexing enough for the sensors at the top to react to the pressure/flex.
Well keep testing and report back.
I'm also having some issues with the touch screen, but it mainly happens with the keyboard. I like to swipe to type, but lately I've noticed that it gets really jumpy, causing thing errors.
At first i thought it was touchpal so i installed Gboard. Problem still occurs.
I also removed my screen protector and tried did the touchscreen test.

I ran the line drawing test a bunch of times and yes, i now do see that mine fails to draw a continuous line on occasion. It only happens in the keyboard (squeezable?) area though.
I'm worried now that edge sense is damaging the touchscreen.
OK, i have ordered HTC u11 this morning from amazon, but i guess i will cancel my order. Had many problems with htc phones in the past. Saw many reviews and thought that this one is perfect with no flaws... Ahh..... Already ordered some accessories for my new device... It's really a shame to read this kind of threads. Hope you guys will find a solution and hope that this won't be a hardware issue.

Does your keyboard collapse when you are typing? That happens with me. Really frustrating when you are typing quite fast then the keyboard just disappears. Then you end up tapping a link or something that was behind the keyboard. You then need to go back to the page you were on and start typing all over again.
Are you running app killers? Stop boost+ auto. Apps updating from gplay can cause you to be kicked out of the keyboard, it can also pause/stop YouTube vids.
The edge sense system is 2 sensors stuck to the inside of the edge of the device, along the aluminium strips, they shouldn't interfere with the screen at any time.
Sweaty hands and greasy screen can cause the screen to misread your touches and gestures.
Running low on internal memory (sdcard) can cause all sorts of issues. Make sure you ALWAYS have a couple of Gb free.
Try to replicate the problem in test mode.

Personally I made sure to address all your points when trying to figure out what is going on. So none of this applies to me.

Same here, only I was told 7 to 15 business days. Offered to give c card to have a replacement shipped, but that is no longer an option with HTC.
So when I washed my M9, I was without a device for 2 days, but now that their phone is crap, it's going to be 3-4 weeks.
Unhappy....
