[Q] Multitouch lag/issues? what could be the cause? - Galaxy Ace S5830 Q&A, Help & Troubleshooting

So I started noticing lag on games with a virtual pad. As in, jump works fine if im standing in game for example, but im running and I try to jump, either it doesnt do it at all, or it does it with some lag.
So I downloaded a multitouch tester and pretty much confirmed that there's an issue there.
If I just touch with one finger at a time, it works fine. If I press with two fingers and keep them there moving them around and whatnot, it also works fine.
BUT, if I keep pressing with one finger and use the other one to do a fast light tap, half of the time it doesnt register it.
Im using the ROM posted here: http://forum.xda-developers.com/showthread.php?t=1583871
wich im finding to be great, but I thought of originally posting my issue there since I gather it is more likely to be caused by software and not hardware.. right? considering simple touch works completely fine.
Any ideas?

Ace supports only 2 fingers at a time. But i did not find any types of lags while using 2 fingers. But it wont work if u use 3 or more fingers at once.

Hey I got 100% same issue too. On original cm7 nightly.
But I found out sometimes it works and sometime it doesn't seems to work. I think it's similar to the rounding bug.
Maybe it's the kernel problem. Just don't overclock and it will work well. Or, reboot your phone and wait for a night without touching it, and the problem is gone. However, the bug will occur again after you install an app or launch an app. This multi-touch bug always occur on cm7. If you don't want this problem you can use stock roms. But if you say touch making it lags, it doesn't make our phone lags or the game you play using this phone is a bit slow. Just the second finger is responding slowly if the first finger is pressed/touched on the screen.
And I've tested this bug using the dev tools in the cm7 rom. dev tools/pointer location. All of the stock rom doesn't have this bug except cm7. CM7 will not have this problem on the first few weeks since the first boot. hope it helps

It's a Ace Hardware issue. Nothing to do about it.

You guys probably overclocked it too much damaging the touchscreen.

this makes no sense mate. The overclock affects the cpu and not the touch screen. Anyway I didn't use any extreme overclock, beside using for a while the Telus Lite with 1.1ghz oc stock. And well I barely played any game, just a lot of emails and surfing on the web, very few calls. I noticed it happens when i move too much, like dancing or when i leave it on the shelf for the night and by the morning it acts crazy

I used to have that issue with stock 2.1 roms.
CM6, Sense mod, fastest Eclare and now MIUI does not bring that night mare back to me.
Also, if you charge using a 2-pin socket [the one without the earthed pin, popular in Asia], it'll show up.
OP needs to be a little more clear, but let me say my results.
Ever since flashing 2.2.1 SBF and then applying a few Froyo Mods and even goign back to ECLAIR,
I noticed that multitouch screws up. Sometimes it things I have a finger on the screen already, so by putting a finger on, it does a pinch zoom on me even though I only have 1 finger on it. Then sometimes it doesn't let me press an icon on my screen insisting my finger is elsewhere. Other times the notification bar starts getting pulled down randomly.
Perhaps Kadalban can explain his Multitouch fix, but for me it seemed to solve a lot of issues. Granted it was only pushed out in CM6 12/4/2010, which gives me 1 day to test so far, but some of those freak-incidents have been disappearing. You'd have to give me 3-5 days to conclude anything, but for now it seems to have done the trick.
i have issue with eclair 3b and CM6....it crazy when i I get my phone out of my pants....
is it FW error or HW error? in my country, in my country there are many like me.and we do not have a solution for this problem rather than the touch screen

how did you fix your screen.my homebutton does not respond
I just changed to some mod roms and the problem disappeared for me.
Some of my friends got really big issue with the touch panel and when they came to Motorola service point, the technicians said there is a known issue with the panel they used but not all customers are affected (hence some people are OK after trying different roms).
So if one experiences it then just needs to go to Moto and they'll change to a healthy-guaranteed panel obviously, if you're still under warranty, it's free!

NeoFroyo!! Well testing

hey guys!
Well i was trawling the android forums and found this!
http://www.neopeek.com/viewtopic.php?t=7524
All thanks yo neopeek for the rom.
I decided to test it out on my kovsky. This coupled with I believe duckkly's kernels worked like a charm!! ill post the kernels up here too as I experimented with quite a few to see what worked best!
Battery life: 8 hours on full blast so i rekon around 11 on normal usage
Wifi: never ever ever dropped on me so far! thou it does seem to be weak in some places around my house where i usually should be getting more signals and strong at places where i get little signal :S.confusing
phone: well calls come in and stuff but sometimes ull see a black screen and cant see who's calling! :S
Bluetooth: paired with my mw600s just fine dont know about file transfer
market:works just fine a bit slow though..could be my internet speeds out here in pakistan.
Apart from that using whatsapp like a charm. facebook apps. gaaps everything works!! not a single sod to date been using it for around about 5 days or so.
Sorry for the spelling errors! big thanks goes out to neopeek and duckkly or whoever compiled those kernels !
PS: oh and the keys will freeze up as you hit around 20% battery. I simply reboot. Also terminal doesnt seem to be working. keeps crashing on me but i dont really ever use it in daily use so it seems to be pretty stable apart from these flaws. Also you'll need to reinstall quickpic from market
Also im on radio 1.16 i believe. 1.14 seemed to drop calls randomly.
please read all of neopeek's instructions before flashing ! happy flashing
can't confirm 20% battery being the point where keys stop working. for me 4 hours of uptime seems the be magic point...
i stopped restarting modules via script (how to has been explained many times in here) and simply restart. most of the time it happens when an app is running - now what good is it if you have a shortcut somewhere, but can't get there because back- and home-key isn't working?!
but yeah, neofroyo is a big step forwards. first time using android on x1 is fun!
for terminal to work you have to reinstall it just like quickpic.
i just hope we'll see some kernel-update soon. without it the whole thing is pointless.
lol truee..thanks for the terminal update. oh if u press the camera button it will take you back to your home screen. than i guess u could load the keyboard modules..annoying i never bother with it. try my combination of kernel it gives me decent battery lifee but yea its the kernel with all the problems. tried the new kernels but they dont seem to work properly
hm, which kernel-version is that?
might try if i know which it is. just had to step down from ygge-monster to ygge-turbo. monster made my touchscreen getting unprecise in left half.
thx for the update with cam-button - never bothered to press that, since camera doesn't work anyway.
yeah, new kernels suck for our device, especially since they're missing the specific battery-driver for x1. the only guy still working on x1-kernel has been silent for months, but i can see he's still at it (porting 2.6.35.7).
Just tried pressing cam-button.
Falls back to lockscreen, after unlock shows homescreen. But system is frozen and after some time reboots directly to android. But lots of stuff doesn't work, especially phone-stuff. So i have to reboot winmo anyway.

i think its the ducckly's keyboard not loaded as modules turbo verison. I believe it should be that because i remember the msm drivers werent really working properly on it

Screen unresponsive

Hi everyone,
I bought a Samsung galaxy s last week from an eBay auction. The phone was described as touch screen lag. I was thinking that flashing a new firmware will solve the problem. I got really cheap though
The touch screen stops suddenly in every 5/6 minutes and I have to lock the screen using power key and unlock again to make it working.
when I got the phone:
Non Samsung battery and chargers were used, I changed and using original ones.
Stock XXJVS firmware in it.
First I flashed stock 2.2.1 froyo and test the screen using *#0*# code. it got pass. But when I start using it, the problem was still there.
Then I flashed stock GB, same story, now slim ics, same thing.
Please someone help me, there is nothing I can do with it now.
I search few threads related to screen problem but couldn't find one with similar problem. So asking here.

Sounds like a hardware problem to me..but it's really hard to say if it is. But it would definitely seem like it since it isn't ROM related. Maybe a water damage or faulty digitizer?

This happens to me sometimes very rarely though, it will be weird and hard to touch but speaking to someone with the same phone they said they had this problem to all I do to resolve the problem is lock and unlock the screen, I thought this was normal?

It shouldn't be normal. I am using another galaxy s for almost two years. But never had this problem in such extent, little bit lag on touchscreen when on froyo. But never after. Now with slim ics Temple run is more smooth then iphone 4.

Thanks for reply. When I got it first time, it was really annoying, the problem was so frequent that it was almost unusable. Now in new rom, after unlocking the screen it works little longer then before. Works like a charm when it works. So not sure this is hardware problem.
Sent from my Galaxy S using xda premium
I don't think this is a hardware or problem either, I broke the screen and replaced it and I still have the same thing when though it is very rare, so if it was the screen it should of gone after I installed the new one, btw I installed a whole new pre built front so the bevil and LCD, and my phone has never hib water damaged? Maybe its something to do with the bootloader? As that doesn't change through ROM flashes

@xsenman;
I did that couple of times going through Advance slim setting. That didn't change anything. Now I'll try this as well.
I change touchscreen into chainfire sensitive option in semaphore app. Still lagging.
Tried over clocking to 1200 but it freezes and automatically reboots into recovery mode. I can use only after changing to default

Guys its really annoying now. Its behaving strangely. I played with it few hours and found out that the screen near the home button freezes first. I cant press the dock but still pull the notification bar? then stops working whole screen. I checked the show touches in developers options setting. Sometimes it works randomly actually without touching it , I just place my finger near the screen but didn't touch and on few occasion it works opposite direction, like I scrolled down but it gone up:crying:
Is this the sensor issue? Is there any way to fix? Any idea please?

Screen+digitizer panel can be changed by yourself. For it, you just need couple of tools and little nerves
Instructions can be found from YouTube, this forum and many other places..

I tried all of those apps, nothing wrong. I think I should change the screen and digitizer, I might need to go to the repair center because my hands shake (my usual problem) and hard to fix tiny things. I want to do few experiments before taking it to repair. I already put it in the freezer for two hours it was acting like crazy after.
Suggest me more...

Me too!
and i thought i'm the only one experiencing this kind of problem. it is exactly what i'm having on my sgs. seems to be temporarily fixed by turning the screen off and then on again, but after a while, the screen doesn't respond on the same spot as you're having.
i've managed a low level debug on screen touch response using adb logcat, and my touch doesn't really register any on adb logcat console.
they might be correct on the hardware problem, but when i'm on any gingerbread rom (2.3.6), the problem is gone.
guys, any idea what kind of drivers they're using on gingerbread for our touchscreen?
I have this too on ics, left half of screen stops responding, lock on/off sorts it....until the next time! Bugs the hell out of me!
Me too! on ICS
btw, i'm already on ics team nyx
change
flash CF KERNEL and put ICS CM9
middle screen not responding
- when in stock gb firmware (official from samsung), the touchscreen problem is gone.
- but i want the features of an ics rom, so i flashed one (first was slim ics); the problem appeared first; first guess was the custom rom was still in its early stages.
- flashed back to gb, no touchscreen problem.
- flashed new ics rom from cm9 (nightlies), problem appears again (ugh!).
- flashed backed to updated slim ics since this was the fastest and easiest to install, touchscreen problem still persist.
- found a temporary fix by turning the screen off then on again.
did a adb logcat full trace log of touchscreen input: what i noticed was the whole vertical middle part of the screen is not responding to touch; dragging touch from one side to middle is working just fine, but not starting from the mid vertical part.
the problem may sometimes go away after a while, and sometimes persist even after the temp fix. it's very intermittent indeed.
help please.

So your sgs touchscreen working fine on stock gb rom! It might not be a hardware problem then. We have similar problem, only difference is I have problem on GB too. I've even tried stock froyo, same story
Sent from my Nexus S using xda premium
same problem here, left part of the screen would be unresponsive at times
can fix by locking the phone through power button and unlocking it, thats why i think its a software problem.
I dont remember having this problem in GB also.
maybe something is messed up during flash?
I have the same problem with ics and jb roms from the onecosmic ics times and i had a topic http://forum.xda-developers.com/showthread.php?t=1648287
I have written here but no one seems to now what it is, i have been using ics from onecosmics first release and had the problem from that moment on, different kernels, roms etc it is still here i have flashed gb again and problem is gone, flash again with ics the middle part still acts sometimes. ?...
We should request from kernel developers and rom developers to look into it. I have tried almost everything no luck so far

[Q] CM7 Multi touch problem(slow responsive)

well hi everyone, I didn't know you guys know it or not. that the cm7 always a multi touch problem after a few weeks since the first boot. but stocks isn't. and this problem is comfirmed i guess cuz i tried many roms. but i always tried it at maximum 2 finger(our phone can only support 2 finger touch). and i used many roms for a few weeks without modding it. after a few weeks, i found out every cm7 will respond to touch screen extremely slow sometimes when 2 fingers taps on the screen quickly at the same time, 2 fingers draw or keep pressing on the screen works normally. stock doesn't has this problem. or you can try it out. this bug will not occur all the time. it's kinda rounding bug(occurs in a certain time), the multitouch will working perfectly without any kind bugs on cm7 for a few hours per day. i don't wanna flash new roms again cuz the bug will occur again if i download, install or even launch apps and i got too much of important conversations/data in my current os. im a music lover so if i flash stock roms the sound isn't that good and loud enough even with patches. it's very irritating when playing multi touch games.
have you experienced this bug before on cm7?
any solutions?
thx for your help

[Q] Touchscreen sensitivity issues in CM9/CM10 (but not webOS)... any advice?

Hello, I am having some touchscreen problems with CM9 and 10, but not with webOS. Namely, I think that the tablet is detecting double or even triple taps when none are present.
In CM9, when I execute a longpress (to move an app for example), the tablet just kind of... spazzes out, and in general nothing happens. In CM10 it also does this, and almost everytime, it starts whatever app I was pressing on.
Also, when I try to type in the CM10 keyboard, 2-4 characters are being entered at a time, unless I touch incredibly lightly, and even then, I will often get two.
There are other symptoms along these lines, like trying to pull up the notifications, etc. This does not appear to be isolated to any one portion of the screen, it is happening everywhere I could check it.
This CM9 versions I have tried are the nightly 0715, and whatever the latest nightly was about a week ago. The CM10 version I am using is jcsullins' 12/16.
As stated, I have zero issues in webOS.
Is there any way to change the touch sensitivity? Am I a moron and doing something wrong?
Thank you for your help/advice.
To clarify, I think this might be two separate issues...
I'm not as concerned with the CM9 issue, as it is only a mild annoyance and everything else is outstanding. CM10 is virtually unusable, however, so I'm hoping someone can help me out there.

I've not had this issue, but this might help. Go here : http://goo.im/devs/jcsullins/cmtouchpad/testing
Download the touch pressure utility (should be the last one) and flash it. Hope it helps.
Good luck.
As an update, after shelving the touchpad for a few months, I have revisited it, and, after doing a clean install of jcsullins' CM10.1 w/BT Fix (20130808), the same issues as above still persist. I've done the following, although I didn't really expect most of them to work:
Switching to stylus mode (no difference)
Changing the accessibility settings for touch & hold delay
Even went so far as to install another launcher (nova) to ensure it wasn't trebuchet (not that I think it was)
Same for the keyboard
This has never been an issue I've seen in webOS... additionally, I don't remember ever having any issues in CM7 either. I did play with webOS for some time today to make sure it wasn't some kind of hardware failure between now and the last time I used it frequently, but I failed to reproduce the problem there.
Is there any light someone can shed on the subject? Thanks!
Thanks for that Chicle_11... I don't know why I failed to mention it, but I did also try the patches with CM9, but it is to my understanding that they were rolled into cm9 nightlies at some point?
I wonder if I could be having a minor hardware issue that just isn't severe enough to display in webOS, because I can't seem to find anything else about this, especially the keyboard problem with CM10. Its bizaar for sure.
Started experiencing the same issues after upgrading from cm9
I recently upgraded from cm9 to cm10.2 and immediately noticed this issue. There were no such issues with cm9. When swyping on the keyboard (any - Google, Swype, etc.), the system registers that I lifted my finger, and so garbage gets typed - you can also see the effect in the trace. When typing instead, letters sometimes double-up for a single press. When playing games like PvZ2, dragging a plant results in a release of the plant before I've lifted my finger, and sometimes the plant gets planted across the screen from where my finger is pressing.
