Touchscreen issue/bugtracker.

I created an issue in the bugtracker about the touchscreen-issue on P990, but the issue (#4012) was promptly marked as invalid.

I've scoured through the issues on the bugtracker, and cannot find any other reports for this bug on CM 7.1 RC1.

There used to be an identical issue on CM7.0 RC1 on the ZTE Blade (#2903) which is marked as fixed.

I'm wondering if someone who has any traction with the devs could please open a ticket.

The issue has been talked to death in various fora, but here's a short recap:

The device is unresponsive when tapping near the right edge of the touch-screen (in portrait mode), or when initiating a swipe from right to left starting near the edge.

It's also unresponsive when initiating a swipe from the bottom edge and upwards.

You can easily observe this behaviour by installing Launcher Pro (free version if you like.) and...:

o Long-press an icon, move it to the right edge to try to move it to another home-screen. The icon "drops" near the right edge.

o Long-press an icon, try to move it to the trashcan. If you move it to far down, the trashcan loses its focus, and when the icon "drops", it's actually below the trashcans focus and doesn't get deleted. The touchscreen does respond though, since you still can move the icon up and down after passing the trashcan.

o Bring up the gingerbread keyboard, type some letters, tap the right edge of the backspace key, it doesn't respond.

o Long press a widget which is as wide as the homescreen, you'll get the resize-widget-box. Resizing it requires a swipe from right-to-left from the edge and is pretty hard to get going.

o Swipe down the notification bar, then try to swipe it up again. Same thing, bottom edge of visible area is unresponsive.

If you do suffer from this issue on P990 and have previously created a ticket/issue in the CM-bugtracker, please see if you can create one for this as well.

I've seen this mentioned a lot but it has never affected me.
[LG Optimus 2x] Rusty!:
You can demo it with a drawing app easily enough, just run your finger off the side of the screen and the line will stop a few mm early.

It's much better than it used to be, so not as noticable in actual use.
[LG Optimus 2x] aremcee:
Invalid issues are usually justified. Did you try to comply with the request?

In any case, that problem was solved 2 months ago. All 4 edges are working fine.

[LG Optimus 2x] TrymHansen:
There was no further request. And it's certainly not fixed on my device. I of course based the report on the RC1-version, not a previous nightly, as it was stated pretty clearly to wait for RC before reporting bugs. The last nightly I tried was #67 (since it had a kernel-update), issue still present.

There *is* a bug here, and quite possibly one which does not show up on all devices. I still think it's a good idea for those who experience it to let the devs know through the bug-tracker, as the devs seem to think it's been eliminated.

Is anybody who turn on gtalk with video on cm7?
[LG Optimus 2x] sibbor:
I'm sorry to inform you that it's not currently possible to do video with Gtalk on Tegra 2 based devices. Google needs to fix their app ;-P...
[LG Optimus 2x] grognaz:
i tested this every nightly since 30 or so with Touch Test and i can not see any improvement at all. i think its just that we start getting used to it....

definitively not fixed on my device.
[LG Optimus 2x] Mjuksel:
Yo every time i try to download a CM7 release the download hangs on 99%...

I cant get any version to download 100% :/
[LG Optimus 2x] aremcee:
"The devs" is me. And I'm sorry to hear that, but I don't see how any further fixing can be made.

The vertical swipe symptoms were originally caused by an in-kernel protective dead buffer area between the capacitive keys and the screen (to avoid accidental swipes into a key).

That buffer has been completely eliminated, and the whole area from the bottom of the capacitives to the top of the screen is now touch-aware (and has been for a while). I have absolutely no idea of what might be causing the same symptoms for some people, but there's no way the problem is the same.

The horizontal right-to-left swipe problem was slightly different, the device had a low maximum horizontal resolution that caused around 10 pixels in the touch grid to be dead on the right-hand side. The resolution has been increased to the maximum (equivalent to 480 actual pixels on the display), and can't be raised any further, either.

I'm not doubting you have a problem, but I can't deal with something I can't reproduce or add debug to.
[LG Optimus 2x] grognaz:
just came to my mind that i tested the side problem on stock rom and it has the exact same deadzone. the difference is that they dont place any buttons near the edge and have the option to move widgets to other desktops by rotating the device... so they definitely know about that hardwar problema and we should all rreturn our devices for display repairs:) sorry for the spaces, really hard to write in horizontal mode...
[LG Optimus 2x] TrymHansen:
That's just not true... for my device at least. On stock ROM it behaves exactly like you expect it to, swipes from right to left works, swipes from bottom up works. Install the gingerbread keyboard on stock, and you see the backspace key works (all of it) as well.

::Trym
[LG Optimus 2x] pastime1971:
@TrymHansen,

you have to understand that cyanogenmod is a community driven, open project, and they try to create a better ROM (than stock). furthermore, they work on their extra time, with whatever the resource they can get. unlike manufacturers who get source codes on every (?) parts inside the phone, there are many proprietary binaries that cm devs can't get an access to, for many reasons.

you can't demand cm team to fix some issues because you are not happy with them. if you are not happy, you'd probably better off stick with stock rom.

if it bothers much, you can try to fix them. all the sources for cm rom and kernel are available from git. (except proprietary parts) if you find a fix, that would be great.
[LG Optimus 2x] TrymHansen:
Yeah, I know ;-)

Agreed to that. The problem doesn't seem to be the touch-screen, but the way "touch-zones" are scaled on the screen, they don't scale the same as the actual graphics, but just slightly less. Dropping an icon into the trash is a good example.

Launcher pro on stock: Grab an icon, move it downwards as far as you can. The trashcan lights up red when the icon is within the "touchzone" of the trashcan, which is scaled exactly the same as the drawable. When you get past the touch-screen area reserved for the screen (which is actually quite a bit past the actual display) the icon drops into the still red "trashcan-zone".

On CM7: Grab an icon, make the same motion. Now when you get to the bottom of the screeen the trashcan returns to gray, the icon obviously having moved past the "touchzone" of the trashcan. The trashcans "touchzone" has obviously been scaled to a slightly smaller area than the actual graphics.

I propose there are some other pieces of code which need the same adjustment. This would account for all of the faulty touch-behaviour.

Very understandable. I hope the above can give you some ideas for where to look.

::Trym
[LG Optimus 2x] pastime1971:
@aremcee,

i wonder if there is a way to map/scale touch input, like from inside 780x460 to 800x480.

it probably would lose some precision, but may cover the whole area ?
[LG Optimus 2x] TrymHansen:
I'm fully aware of what CM is, and I'm not demanding anything, I'm trying to help. I don't think it would be beneficial to release a version with potential problems for some users if it can be fixed before release.

I'm sorry you took this as a criticism or a demand, that was never my intention, and if you read my posts again I think you will find neither.

::Trym
[LG Optimus 2x] pastime1971:
i just tried Dev Tools > Pointer Location.

in horiontal mode, pointer well registers from 0 to 912 pixels (well beyond the screen into touch keys region)

edit: i printed out the actual key coordinate while using keyboard.

coordinate reported goes up to 797 (out of 800) and 478 (out of 480), which is pretty good, i guess.
[LG Optimus 2x] TrymHansen:
True. A few posts back I explained that it is not the touch-screen itself that is the problem, but how zones get set up to listen to touch-events.

::Trym
[LG Optimus 2x] pastime1971:
it sounds like if you touch the edge of lcd screen, the position is not valid (out of bound, 480x800), and apps don't know how to handle it, because touch region is bigger than lcd, am i correct ?

edit: my 'backspace' seems to work just fine. even 'p', i can touch about 70% of it from the left. you can't register 'p' ?
[LG Optimus 2x] TrymHansen:
I have a Norwegian layout, with an "å" to the right of the "p", and it's a tight fit. I can get it to register, barely. I don't have a capacitative stylus, so it's a bit hard to judge, but I'd venture only the left 30% of the key registers taps.

Anyway, I think we should stop polluting this thread with more of the same, as I said in my first post this issue has been talked to death.

I have a feeling aremcee already has a good idea about what's going on.

::Trym

(I did some testing of my own, didn't find enough to find out exactly what's going on, but did notice a peculiarity about the stock touch-handling. It clamps the y-values to about 790. In other words it registers touch along the bottom edge, but sends them back to the touch handler as being farther up. That explains the difference in the vertical handling, why on CM you can actually drag items past the bottom edge/trashcan. CM should propably introduce clamping of the reported y-value as well, but up to the full resolution of the display - 1.)
[LG Optimus 2x] johnnydj:
I'm using ADW Launcher EX with RC1 and while I had the problem months ago like switching home screens with dragging your finger from the right side, from outside of the screen and didn't work, it definitely works now.

I can't see why it doesn't work for only 2-3 people, but it works for others.
[LG Optimus 2x] vitaminxero:
If we assume they're using pure CM builds, we can consider physical issues. Screen protector, perhaps? =P
[LG Optimus 2x] gensplejs:
+1 touch problems at screen edge and buttom (rc1 and latest nightly) but its fine on stock. It actually seems like stock rom maps touch outside the display area to the edge of the display area.
[LG Optimus 2x] pastime1971:
i'm looking into kernel source, and it seems like FEATURE_LGE_TOUCH_EXPAND_HIDDEN_ACTIVE_AREA in arch/arm/mach-tegra/include/nvodm_touch.h is undefined, which, when defined, forces pixels 800 to 830 to register as 799. (that behavior seems to work fine at horizontal left side. you can come in from out of bound and recognized once it enters.) i suspect that having touch button (and its hanlding) seems to prevents it.

i tried to define it, compile the kernel, build a kang, and tested it, but no dice. it feels like some of forcing part is missing (when out of bound is first pressed.)

if anybody has a good idea, please take a look at it.

edit: i may be wrong, cuz it seems currently 800 - 820 is forced to be 799, so those files may not be the right ones to look at.

Is it only me that has random Freezes in Cm7?

Somtimes when screen is on, and sometimes when screen is of... And then i have to pull battery out....

Btw, CM7 FTW!!
[LG Optimus 2x] LeJay:
If I run my finger from the edge of the phone and on to the screen it doesn't recognize my touch no matter what I do... I have to release my finger and repress... I assume this is a 'feature' to avoid unintentional touches. Is there any way to allow it to always recognize my touch?

EDIT: It's only from right to left.
[LG Optimus 2x] spences10:
No I'm getting random freezes too
[LG Optimus 2x] machtwerk:
Those of you who are running the latest kang version: are there changes in the /cache partitioning? And did you do a full wipe before flashing or just flash over the previous nightly/kang?

Having some weird behaviour when locking screen. It will go black and then change to a dimmed lock screen, before going black for good. Yet no freezes or similar until now.

Does anyone have the screen off animation working (saw it on a friend's DHD and wondered if it is part of every CM7 system, as I see the settings but no effect).
[LG Optimus 2x] nattskift:
When questioned about the screen-off animation, arcee anwered that..

@AF9210 we didn't enable them. On purpose, they look like crap with the current backlight driver

[LG Optimus 2x] chong81:
When I flashed 622 baseband and RIL, my battery life suffered (4-6% drop on idle). I flashed back to 606 baseband and RIL yesterday, and so far my battery life seems to be back to normal (2% drop on idle).

BTW I'm on MCR FR19, but keeping a close look at CM7's progress :D
[LG Optimus 2x] omiblack:
You waited all this nightlies just for that?
[LG Optimus 2x] jwedda:
After abandoning CM somewhere during 3x nightlies I have just flashed 622 with 67 (68 and now 69 ).

Gamelofts Modern Combat 2 still doesn't work, but wow! CM has improved a LOT.. First of all, no more battery pulls for 24 hours :-)

Personally I had the LED backlights completely turned off. Don't like them at all, not even for notifications. I used one of the tools available on the market to do this. Sadly now the backlight is controlled by the brightness controls. I have searched the thread and I haven't found a fix or workaround yet. Does anyone know if that's being worked upon?

Modern Combat not working (yet) is something I can handle, having my lights do unwanted stuff is not something I want to deal with long term.

So it seems to me some kind of java thingy? I have no clue.. I haven't touched any system settings, am running the kernel that came with the nightlies ..

Annoying issue : s

I updated the gallery app to gallery 3d in the marketplace. big mistake.

I now have an icon where the gallery app was called com.cooliris.media with a default icon. When i pres it it takes almost a minute to load the gallery.

It wont let me uninstall from either the market or the apps section in settings, has anyone got the default gallery used in cm7 that i can either restore through cwm or by installing a fresh apk?

and both times BB 502 and RIL 502

no new apps or anything, I think it's an stuck process who stresses the cpu, but nothing to see in a taskmanager, strange...
[LG Optimus 2x] djmcnz:
That's good battery performance relative to the norm. Your previous experience is extraordinary.

Unfortunately you can only hope for, not expect, extraordinary performance. People should expect 10 hours with moderate usage (not more than 3 hours usage really). Sucks but a reality nonetheless.

@ TrymHansen, johnyd, and anyone who is bothered by 'p' key

i don't have ADW Launcher EX, so I'm not sure how to test it.

but i compiled a kernel with FEATURE_LGE_TOUCH_EXPAND_HIDDEN_ACTIVE_AREA (+ some tweak)

now 'p' key registers by pressing the right edge of it.

you can try the kernel at http://xdaforums.com/showpost.php?p=15408224&postcount=149

if you are willing, try and see if it helps.

p.s. kernel has no problem seding touch event to LatinIME.apk. but LatinIME.apk has an issue that the far right (pixel 799) doesn't register. the far left (pixel 0) does. i had to crop one pixel more (make it 798) for LatinIME.apk to register.

I've modified some GPS settings based on Modaco and it looks like there is some improvement. After few short tests with Endomondo and Sports Tracker, everything works fine. Before neither of mentioned apps worked with CM7. I hope this will be published in next CM nightly and you could try it :)

[LG Optimus 2x] pastime1971:
so that means GPS is always on as long as there is an app that uses it ?
[LG Optimus 2x] grognaz:
i just tested that kernel, first with the app "touch test" and it seems to be a bit better than usual but still jot perfect. the i tested it on the keyboard in horizontal layout where i usually have a hard time with the bottom line keys (space,comma,point) and there i really notice a improvement. as seen in the touch app its not perfect but definitely a lot better than before.
[LG Optimus 2x] Ph4nt0m_:
Yes. At least with Sports Tracker and Endomondo, which I've tried, because they didn't work for sure before changing the code. I've run each app for 5 minutes (with screen off) and GPS was still working...

i believe it is related to lejay's recent commit. http://review.cyanogenmod.com/#change,5743

in particular "params.setPreviewSize(1280, 720); " in CameraSettings.java

i had noticed that even before his commit/mod, zoom menu disappears at High setting, which is 1280x720. somehow, our camera doesn't like 1280x720. (not sure why) i had reported it to lejay at http://xdaforums.com/showpost.php?p=15262242&postcount=175

making preview 800x480 seems to solve the issue. i made a new Camera.apk that prevents it at http://xdaforums.com/showpost.php?p=15413384&postcount=210
