Touchscreen goes out-of-sync on Froyo - Nexus One Q&A, Help & Troubleshooting

Tried searching first, sorry if already reported. I'm running the Modaco Froyo ROM, with pershoot's .34 kernel.
After about 1/2hour or so of playing any touchscreen intensive games (ie... Robo Defense and Super KO Boxing 2) the touch sensor goes completely out-of-sync. Anything from touching the screen causing a haptic feedback (as if pressing one of the softkeys) or pressing on one spot of the screen and it registers in a completely different region.
I've never had this issue pre-froyo (as has been reported by folks using 2.1).
Anyone else getting similar issues?

I've been getting this issue since 2.1, and had it for the brief period of using 2.2. Don't think it's been fixed yet. Annoying, but you can always just toggle the screen with the power button to get it back to normal.

Thanks for the workaround tip, heck of a lot better than having to reboot.

G1 Unresponsive - Requesting Help

My friends G1 is unresponsive whenever the screen is closed, but seems to work when sliding it open. The funny thing is, while the device doesn't perform any actions when the screen is closed, it still seems to be responding to touch. When the screen is opened again, your touched actions will "catch up" and the phone responds. This happens from recovery mode as well as in Android.
Can anyone help?
Anyone? Please?

The phone is in standby/sleep mode while screen is off, so you cant use the touch screen. You must double tap Menu to get to the home screen.While in recovery mode you cant use the touch screen cause you have to use the hardware buttons or the trackball. Im guessing you were unaware that the phone goes into sleep mode. When you slide the KB the phone wakes from sleep mode and allows you to use it.You only have to slide it when you need it not just to do it randomly.
No no, sorry if I worded it incorrectly. The screen is on and it is frozen when the slider is closed. Once you open the keyboard, everything works fine. As soon as you slide it in, the screen freezes on its current display and stops updating.

What rom are you using?
If it is a hero rom then it doesnt work while in landscape mode so you cant open the KB while on home.
Its a 2.1 ROM by Kingx
The screen behaves the same in and out of android though...such as in the recovery (JFv1.4) console. If the screen is closed, the screen "freezes", but the frozen picture is still displayed. If you slide the screen ouţand expose the keyboard, it works fine. The phone otherwise operates normally, as does the standby mode.

You need to upgrade your recovery though

Try wiping and reinstall the rom and wipe everything.Also you need a task manager cause you might have a billion apps open.
I'll try it on his phone when I get off work. Thanks for the recovery link. Do you prefer this over JF?

JF is super old and lacks many features from Amon_Ra. But it's based off of Cyan 1.4 recovery. It makes a lot of things easier like partitioning,wiping,backup,restoring roms.
Alright,
Home now with his phone. I swapped JF's recovery with RA. The issue still exists, and I'm wondering if it's hardware related...
This is frustrating. I don't know if I can fix it for him...
The problem seems to have gotten worse on its own. If the screen is closed at all, the screen will go black with a slight image shown with what seems to be an unworking backlight. However, upon sliding the keyboard open again, the backlight does not return until the device is rebooted while leaving the keyboard open.
Edit:
The backlight seems to come on sometimes when you slide the screen open...

You might wanna wipe and install another rom to see if the problem stays.There might be a hardware problem with your phone.
I've wiped and tried a couple of other ROMs but the issue persists. If it's a hardware issue, is there anything I can try to fix it?

It could be the ribbon that connects to the display.If you can find the assembly guide you could replace the broken or loose piece.But i'm not 100% on which part of the display needs to be replaced.You could ask someone at T-Mobile or at a electronics store what the problem is.HTC offers a free 2yr warranty so you might be able to get a replacement.
Bumping this to see if this was ever resolved. Having the same issue, and considering replacing it brand new, but wanted to know what exactly needs to be replaced so I can order it.

Interesting Problem with My I9000M

So the only tweaks I have installed on my phone are the Voodoo Lagfix + Colour.
I was just wondering if anyone else is experiencing this problem. Essentially the phone will turn itself off (I think, it refuses to wake so I have to hold the power button until it reboots)
It happens if I have it in my pocket, have it on my desk, pretty much anywhere at random. It occasionally freezes on the main text messaging screen.
Just wondering if anyone knew why this was happening/ how to fix it.
EDIT - Disregard all this, just read through the entire comatose thread.

[Q] Looking for Softkey Backlight Extender

So I have spent the last 3 hours scouring the site and web looking for a theme that works like the Blackmod Enhanced theme for fascinate. Have not found a single thing to mod the backlight timer so maybe can't be done yet. Anyone tried that theme on the captivate?
I am rooted and tried cog 2.bv6 but it killed my wi-fi at home which was a deal breaker for me. This time trying to just tweak the stock eclair and really would love to have the 15 second extended backlight for the soft keys, the enhanced power button with reboot, recovery etc options, a battery percentage indicator (and full flash support, I realize that is more than just theme based and gets into full blown ROM's but doesn't hurt to throw it in, getting by with Skyfire browser for now)
Anyone know of a theme or very very very stable ROM that will give me these features? Backlight is the biggie as it's the only thing I can't stand on the phone.
Rob
:edited typos
I flashed Assonance 4.3, disbled the lagfix, flashed SetiroN's 1200MHz 1.4.5 Kernal, followed by the gingerbread theme (I only got the theme to flash by renaming it to update.zip and flashing in recovery manually) and it is running very stable and has backlight notifications.
AFAIK there is nothing that currently extends the backlight to stay lit longer. I'm hoping someone figures this out soon because I'd like the keys to stay lit for as long as the screen is on. The only thing available is backlight notifications which are lit up when you have a new text, email, or missed call.
I would love to have them on while the screen is visible (Except for video watching) as well. I wonder why manufacturers don't use a technology similar to the screen like the nook for the buttons? It would just be backwards... have it be all dark with a bit of the lighter color showing through. It would be easy enough to see and not take hardly any battery power right?
So this looks to be possible right now; however, it would be exceedingly difficult to do this in a sane way. For example, how do you know when to turn the lights off? Should they just be kept on until the phone falls asleep? I'd have to dig into AOSP a lot more, but I'm thinking this isn't a cut and dry easy to implement feature by any means.
Was talking to someone about this in another thread and there was a misunderstanding. The point to extending the backlight for the soft keys, for me anyway, would be to keep them active thus eliminating the need to touch the screen to enable the back or home button (or pressing the button several times to get it to wake up). Just in case someone had the wrong impression of the goal here.

I think just giving the option of the length of time someone wants them to stay on kind of solves this. I would love them to stay on for 15 seconds or so instead of the 3 seconds it is at now.
Ya I seriously would like this implemented. DEVS someone please try to do this. I would gladly be willing to donate for it.
So I wasn't clear before. I'll try again.
There are technical issues with detecting when the user has stopped touching the screen. It isn't as simple as raising a timeout value, you'd have to create an application that was constantly monitoring all gestures, using a good bit of processing power and battery.
This appears to be controlled by hardware for the most part.
How about as a start the application can at least extend the time to 15 sec after any one of the bottom 4 buttons are pressed.

I would be happy just having the lights lit. The key activity for the 2-3 seconds is fine.
I am getting old i guess and need to see where the keys are
On Di11igafs 2.5 they stay on at least 10 seconds so there must be a way..

[Q] Captivate Temporarily Sticking in Landscape Mode

I have an odd issue that seemingly started out of nowhere. If I turn my phone to view the screen in landscape, it won't switch back to portrait when I flip it back upright. It doesn't matter what app I'm using or if I'm on my home screens.
I can turn it off and turn it back on and it will correct itself (assuming I power back on holding it upright). When I say "turn it off" I mean just turn off the screen, not a full reboot. What is odd, is that if I flip the screen 180 degrees it will reorient to the other landscape - but never go back to portrait without powering cycling. To me this seems to indicate that it isn't the accelerometer, but who knows?
I was running CM9 nightly from 04/19 at the time and updated to the 05/12 nightly to see if that would fix it (and see what was new in the ROM). I am on the stock CM9 kernel, no OC/UV. I am running LauncherPro free version.
I'm not sure if some random app may have updated that started this or what. I hadn't changed the ROM or monkeyed with anything for at least a couple of weeks prior to this.
I did a search and the only similar issues I found were all from last year and it seemed like "DeskHome" app was the problem. Most of those folks were having it permanently stuck in landscape, where mine will correct itself by power cycle.
Mostly this is just annoying but I'm hoping someone can help.
Anyone else experiencing this? Any suggestions what to check?

[Q] HP touchpad cyanogenmod touchscreen issues.

I have been having problems lately with my HP touchpad on CM9. They are as follow: the touchscreen goes crazy and does all sorts of random typing and button pressing. At one point I could not use it so I webOS doctored it up and then flashed CM10. So far it fixed the issue but now my corner "back" button only works when you press it on the side closest to the middle. Some other buttons are like this or do not work completely in apps. I don't think it could be a hardware issue as I have always been careful with all of my devices. Thanks in advance!
Can you completely rule out hardware issues by testing your screen using a drawing app?

I will try that now.
Update: Ok please try to work with this: In landscape look at the arrow, the width of the arrow, that entire section is not working from bottom to top. You have to almost tap on the very right edge of the back arrow. I still do not think it is hardware.
Bump, please help
I'm on CM w/android 4.2.2 and have similar screen issues... screen sometimes goes a static non-moving "fuzzy" blue... not sire if ther is any pattern to it or not, but reboot fixes it for a while.
lately I've noticed that ill get artafacts... fpr example todays google doodle viewed using stock android browser app will often produce black a d white horizontal artafacts. perhaps driver issues?

You don't say what Rom you are using but it certainly works on Jcsullins latest.
Evervolv but now i am thinking its an lcd digitzer screen problem cause nothing in that area works regardless of the rom. I never dropped the device so i am not sure why just a section of the lcd screen would stop responding..
