Disable trackpad - Desire Q&A, Help & Troubleshooting

On my HTC Desire my trackpad had a horrible habit of randomly generating inputs.
Generally it is isolated to a couple of minutes and then it settles again but for those couple of minutes it is rather infuriating. It makes me deselect text, navigates around webpages, switches my home screen and all sorts of things I don't want it to do.
It has done this since I got the phone really and seeing as it is an intermittent fault I couldn't be bothered chasing it up. So it is a hardware fault as far as I can tell being that it occurred on the stock rom, then on RCMix and F1 Ginger.
I'm currently running Oxygen, bravo hboot, s-off. And was basically wondering if there was a way to permanently disable the track pad as I could live without. Soft disabling would be just as good as I could just switch out off when it goes mental.
Any ideas, thanks!

hi
i just saw the thread. I disabled the trackpad of the desire before. the way i did it was to disable the kernel module in the kernel-conifguration. then i compiled it and it worked. but you won't have the option the enable or disable it by software.
here is a link to the tread with some kernels: http://forum.xda-developers.com/showthread.php?t=981242&highlight=trackball
if you are interested in another kernel i will try to build an update for you.

4 Hard Button Go Crazy on Android

I installed the Android OS on my phone that was found on this post:
http://forum.xda-developers.com/showpost.php?p=5480057&postcount=7353
I updated it and everything to what he has but occasionally my hard buttons at the bottom will either stay lit or not respond at all. Or it will even go crazy as if I were sitting there spinning my finger around the middle hard button thus making it highlight everything on my menu. That also causes trouble because then it thinks that when I press the home key it decides to bring up the call log screen.
Is there anyway to disable the "iPod Scroll" on the center hard key?
Dude. You should update to the newest build. And update Rootfs and zImages.
everything is in the XDAndroid thread in this forum.
I updated to the one found here:
http://forum.ppcgeeks.com/showthread.php?t=104276
And my scroll wheel and hard buttons still mess up from time to time.
What device do you have? RAPH100?
Sorry I don't know the developer names but its the HTC Fuze for AT&T so it's either the RAPH100 or just the RAPH. The start up config I'm using for Droid is the RAPH config.
Its best not to touch the capacitive DPAD and scroller during boot up. (safe time is when you can see a n d r o i d or the bootscreen.) This and having the pad clean is very crucial if you don't want it going crazy.
Try cleaning it with a wet cloth/tissue and try again.
I also had a screen protector which was massively scratched which caused problems. Ever since removing it the DPAD has been working great.
dude i totally have the same problem.
i ve tried wipe it clean but no luck.
sometimes everything work great but all of a sudden the buttons go wild and start flashing. after that, nothing will bring it back to normal. maybe after a few minutes if will stop blinking, lefting one or two LEDs on, and the button is then less responsive, though still works if you place your finger on the button you want for a few seconds before pressing.
I've seen a few people complaining about this but other says its because of our own device...
However everything works normally in WM... so i guess it might be about the sensitivity or something like that.
no matter it get fixed or not, I do want a method to disable the scrolling too, and maybe the left and right buttons, because they never work even under WM...
Yeah, mine does that too. Its random, sometimes not happening for days, then all of the sudden it starts. And this is within the same boot. Very odd. BTW, I keep up on all builds, always update asap, and my pad is spotless. I can't really figure it out.
also getting the exact same problem a lot, with everything up to date, clean, and not touching on bootup. would it be difficult to implement a code where we could just disable the middle scroll wheel? thats the thing that causes the most problems, and its not really that useful anyway.
@reverendkjr
This may be off topic but, you say you leave your phone running Droid all the time? How do you not drain your battery in like 4 hours unless you leave it charging all day?
But I'm pretty sure I'm as up to date as I can be and I still get this issue.

Its not off topic at all. I have been using Xandroid as my one and only OS for about a month now. I do charge it quite often, and I leave it on my desk at work on a charger. I also charge it at night as I sleep. I start off the day with 100% and can go 6 or so hours without issue. I continuously get 3-4 days in a row without a reboot or a failure. I find that it has become a suitable alternative to Winmo. The difficulty that I have is that there are primary functions which I miss a bit (camera mostly). But I feel that in order for me to fully understand and appreciate this, and to be able to contribute as a quasi beta tester, I must be willing to spend as much time with it as possible. I keep up with these forums on a regular basis , checking them sometimes 2-3 times a day. It is difficult to distinguish helpful info sometimes, since there are several versions floating around, and not everyone has the same setup & environment. I search as much as I can to find my own solutions, and for the most part, I'm relatively proud of myself. I usually only chime in when something is really bugging me, or I see something valuable that I can add to a conversation.
This issue was one that I had seen a few people talk about, and it had always been chalked up to being a dirty sensor type of thing, or someone touching the pad while it was booting. Having tried all of these solutions with no success, I had come to the determination that it was not constant, it could be ignored or dealt with, and eventually someone would fix it. It is most definitely not a "hot" item, so I never made a stink about it. Now that others have brought it forward, I decided to add my experiences.
I have loads of respect for the developers, and realize that they are not doing this for me. They are doing it for themselves, and fortunately, they share it with us. I am envious of their ability to make this project possible, and have no expectation or demands. I just take what they give us, and try to make it work for me.
Just my two sense, I'll step away from the pulpit now.

May I appeal to the developers to move Raph110 Navigation wheel to "Not working" so further development can occur. I do not touch the wheel during boot, but it still randomly flips out. My screen is clean. I did the clean cloth thing. The Navigation wheel not only flips out going all over the place. It actually rarely works the way it should in any application.
All I really need is to turn it off or disable the Navigation wheel if at all possible. Is it necessary to load the Nav-wheel capacitive drivers or can we disable them? Would it disrupt the function of the D-pad if disabled because all I need is the D-pad.
Chime in RAPH110 guys. Would you care if the Nav-wheel was disabled, because I actually think this is what is causing the issue.
I just want to make sure that I communicate to any developers that this is not a major issue. To me, I feel as though this is the only issue that I have at all. With the build I use, I honestly have no other issue which means that the Raph110 Android end product is 99% complete. To be direct, Thank you! I feel as though you purchased me a new phone, so this is no way a complaint. It is only the last 1% quality assurance analysis. ;-)
Edit: I just re-read this thread and the common denominator is HTC Fuze or RAPH110 users are having this minor issue. RAPH100 posting are saying "Just read the thread" or "use updated packages" or "clean the screen" which I think may all work and be valid for you RAPH100 users. I can indeed say without a doubt that this does not work for RAPH110.
In order for me to stop the random D-pad/Nav-wheel random scrolling, I have to screen lock it, let it go to sleep, then it might stop. It does stop mind you, but it is quite random how I am able to stop it.

I think mine is a RAPH100... i cant take out the battery and double check... but mine is a unbranded version fron 3 australia... which i remember is raph100. and i totally have the same issue so this is not only happening on raph110 i believe.
Hey guys,
I was having the same problem in wm6.5 using many different energyroms, i disabled the scrollwheel altogether within the registry, never used it anyway. I am now getting the same problem in Android. is there is a registry parallel in android?
btw using a RAPH100 (all above fixes did not work)
devs, is there no easy way to implement a disable scroll wheel setting?? i swear that wheel will drive me crazy at times
While this could be an issue with all Raph 110's (AT&T Fuze), I think it is just a subset due to hardware problems. For me, the problem only happens occasionally and it does not only occur in xdandroid, but also in WM. There is an HTC tool (for WM) named NavDbgTool.exe that will show you what is happening with the capacitive buttons/touch area on the Raph. For me, when I have issues it lights up all over and shows touches occurring that are not occurring. I know of at least one XDA member (Captain Throwback) who was able to get a replacement phone (a Tilt2) from the insurance carrier because of this issue.
Perhaps this is a problem that eventually happens with all Raph 110's due to a hardware flaw. If that is the case, maybe enough complaints to AT&T will cause them to replace all of the devices (similar to how Sprint is replacing all their Touch Pro's due to overheating issues). In the meantime, if you have insurance, you should be able to get a replacement phone, just use the NavDbgTool.exe to document the problem in WM.
Also, due to this issue, it would be nice to have the option to disable the capacitive touch area on the Raph 110 in xdandroid (while keeping the D-pad working). I don't use it for anything now that zooming doesn't work for recent versions of Opera in WM.
I'm starting to think that this is Winmo ROM related. I noticed that since I've used the ROM that I have installed right now, the amount of times this issue has affected me has been slim to none. I am currently running the an NRG rom from june 12 with sense 2.5.
link: http://hotfile.com/dl/47992175/ccd8b44/Energy.RAPHAEL.21905.Sense2.5.Jun.12.7z.html
I'm not guaranteeing anything, but its working for me.
Maybe it has something to do with a package that is built into certain roms. I have noticed a few times where the winmo ROM i have loaded will affect Android's performance as well. The ROM that I am currently running was also what provided me with the ability to get GPS working in Android.
I hope this helps some of you.
I don't think it has anything to do with WM. For me, it only happens in Android.
firstly i have a raph100 that has this issue too, so its not just raph110
secondly, for me, this happens in wm too but a lot less frequently and seems to repair itself. It happens in android 70% of time when i boot, the 30% else happens later...
newly released zimages seem to shutdown the capacitive panel when sleeping, and this solved my problem a little bit since every time it goes crazy I can put the device in sleep then resume it...
But when it goes asleep the two buttons on the right act as back, the two on the left act as home. I think there is only one physical button on both sides, the touch figures if you are pressing back or end.

[Q] CM6 Final - Help! Almost perfect

I know the first one is probably nitpicky. I did just finally get CM6 to the point where it's buttery smooth, faster than EVERYTHING else out there, and works 99% how I want it to. A few things that bother me yet, and I'm hoping someone can help me out. I have read through all (yes, all 700 odd pages) of the CM6 thread here, as well as checked over the cm wiki, the cm snap thread, and even delved into the source for one thing (battery related, different thread). What's left is low hanging fruit that hopefully is just something that's common knowledge that I missed.
Running CM6 final, with GAPPS from 8/17, snap 8.2-850 on a nova 002
Jittery fade on screen off:
This was always described as a "smooth fade" when the screen turned off by my friends. It's much smoother on theirs, but when I turn my screen off, it's like it's only hitting 3 brightness levels before it goes off, and it takes FOREVER to finish the process (1+ seconds) after I've hit the power button. I have disabled setcpu profiles in an attempt to fix, as I've got a screen off profile. No dice.
Settings->Sound crashes every time:
Pretty much just as described. I simply can't enter this part of the settings application. That means no ringtone changes, I've got to use a different app for volume adjustment, etc. etc. Basically, it's a pain. Attached is a logcat excerpt from when I ran logcat via ADB while trying to diagnose myself.
The first question to ask is..Does it do that without the snap kernel?
im running snap kernal and have neither of those issues.
Yes, this happens using snap or stock cm6 kernel. I did want to post that i was using snap to give a clear picture of my current phone conditions though.

[Q] Trouble with all android software

Hello all, First, I searched the forums for my answer with no such luck, that being said if Im repeating a question thats been asked I apologize. I have a problem with keeping android stable. I have flashed with different versions of windows several times all with success. I do however, prefer the android system, I find that it runs much better, faster and has better perks. Everytime I flash following the original how to, I run in to a couple similar problems.
The first is when I hit the power (not hold the power) the back light cuts off and the keyguard enables, the screen goes dark all as it should. Depending on the time ( the longer it is the worse it is) when I hit the power key to revive my phone, I often get a white screen, then it waits , then it goes dim, Sometimes If I hit the power button several times it eventually comes back to the key guard option, but others I have to remove the battery and reboot. This is the major problem, as I cant use my phone when I need it. This problem seems to get worse the farther it gets away from the flash date, e.g..,, after a brand new flash it works pretty good and then it goes downhill from there.
Second, it seems to lock up when I let it charge overnight, not always (but most of the time) I get up, click the power button to revive the phone and I have a white screen before me that is frozen solid. This like the previous problem seems to be linked to the distance from the last flash.
I hope that its something Im doing wrong, as Im currently using wmobile 6.5 and since Ive had a taste of the droid os, my wm phone is just disappointing. And as I was unsuccessful in finding a post that adequately describes my problem ,Im hoping that there is a way around this .
I have tried, Incubus Superfroyo, Wrym warm donut, and Cyanogens build. Im sure Ive tried others, they just escape me, I was re-flashing daily until I went back to windows. I truly hope someone out there has encountered what I have and has a solution. thank you all for what you do, these forums have been extremely valuable and helpful.
Sounds like you have the wrong panel type selected. Is it set to auto? if it is, try setting it to 2 instead. That cleared up the problem for me.
Tried all panels all have the same problem.
Well thanks for all the many replies. I give Ive tried everything on this site and m android is still really glitchy. Guess it will be windows until I get perhaps a phone capable of running android smoothly.
What kind of phone do you have?
Sent from my HTC Vision using XDA App
do you have an SD card you can try to boot from and share your settings?
What we need to know is which kernel you're using, or an image of the kernel you currently have. Also, we need to know which radio version you're using, as this can have detremental effects on stability as well.
Personally, I have been using radio version 1.70.19.09, which seems to be the most stable with kernel .25 IMHO.
I have also "personalized" ThoughtlessKyle's "Fat-Free Froyo", adding/removing apps that I need or don't use respectively (navigation, QQPlayer, Pandora, etc.).
Currently, I think I might be one of the only people not experiencing any issues with this phone running Android 2.2.1. I do get the occasional "hang" (I wait for it to finish what it's doing instead of force close), but that usually has something to do with network coverage or an app requesting something from an unopened port.
Old phone, new OS and runs smooth as could be expected.
Next for me will be the HTC HD2 (if I get one at the right price, the tilt was free)...
I know, I know that MANY PEOPLE THINK OF THE WAKE UP WHITE JIBBERISH SCREEN as NEVER WORKING.

Ill try that combination and post my results. The latest I tried was
Scoot CyanogenMod 6.1.2 RLS6 with 2.6.32 still no joy, white screen crashes and hang ups. and it seems progressively worse the longer the rom is on the phone. To whomever asked what phone I have, its the at&t tilt II

I can't help you regarding panel selection but, please have Radio ROM version 1.65 or higher. And do give my fresh foryo a go with 2.6.25 kernel (everything is there in the thread on how to use it with 2.6.25 kernel).
the WHITE GLITCHY SCREEN IS THE PROBLEM WITH ANDROID DRIVERS. Install with Data on SD Card often causes lockups / force closes.
I am using panel type 1 and white glitchy screen stays for like half of a second and next moment I get a nice clean keylock screen. I don't know but its like 20th time I am explaining the problem related to LCD
Change Panel Type, Get a compatible Radio version (1.65.x or HIGHER)
You say that often install with data on the sd card causes lock ups and freezes. Can you explain further what you mean ?

Ok, so I installed your version of froyo, the accompanying 2.6.25, the radio that you use. For the most part the hanging up is fixed. Now the second problem is still in place. Sometimes when Its been in hibernation(or whatever you would call when you hit the power button once ) when I attempt to refresh my phone (hitting the power button once) nothing happens, the green light is still blinking at the top but the screen stays blank, normally have to remove the battery and restart to get back to using the phone. Is this a sleep setting? or is this something Ive done wrong during the installation.

[Q] Safe Mode / Optical Trackpad Issue

hi, very new to all this, never had a "Smartphone" of any type, Anyway, I was given a dead Desire to play with, it would not charge, so I got it going by putting 9V across the battery for 30 seconds to kick start, then it charged nicely. But it kept crashing on loading the standard O2 firmware. When it did load the volume down seem to be stuck (it wasn't it seems though). So I rooted it for flashing.
Anyway, tried a few ROMs (BeanStalk 4.4.255, MildWild 8.0JG, MIUI XJ 2.3.7, OxyZM 1.2) - all load but always the Desire runs in Safe Mode. This is shown by the words "Safe Mode" in the bottom left of the screen and a failure to run any downloaded Apps.
Other ROMs (BCM-RC4.1U2 and Carbon KK Unofficial 20140430) run without Safe Mode and only minor glitches (most prominant seems to be an inability to enter 'standby').
Anyway, I'm trying to figure this all out. I now know the Optical Trackpad does not 'track' (ie does not react to swipes). Took me a while to figure as I had no idea what it is supposed to do. It does react to pushing (as some type of 'OK' button).
So, having read loads on the web it seems a failure in the Optical Trackpad makes the Desire run in Safe Mode. Likewise its failure seemed to interfere with the volume down in the original O2 firmware. The failure does not seem to be a problem newer Android versions (I think the BCM and Carbon ROMs use newer versions).
Anyway, anyone got any experience, ideas or suggestions. The phone is a great toy and I love a challenge, been good fun getting this far on a "dead phone". Really impressed with the screen, given I had never used a Smartphone before.
Anyone got an idea why earlier versions of Android cause the HTC Desire (with non-working optical trackpad) to go into safety mode, but later versions (v4 ish) do not? All for interest really, it is working pretty much 95% on 4.0.4 (Nikez Lente). Just minor issues on sleep and occasional volume changes - use "Black Screensaver" and that really helps conserve battery.

[Q] Touchscreen issues on 4.4.3, HELP! (Bounty Avalible)

I updated to GPE 4.4.3 through the RUU recently and have had some pretty bad persistent touchscreen problems recently.
I have turned show touches on in developer settings and discovered the the issue takes two forms. Sometimes the screen has trouble tracking my finger. Ill swipe my finger around, and the phone will not register my finger smoothly unless I press down hard. Then sometimes this issue will randomly fix itself and the phone will smoothly track my finger on the screen without the need to press down hard. When this happens however, a new problem arises. There will be a persistent ghost tap in the upper left hand corner. The screen thinks it's getting repeatedly pressed. Additionally, the location it thinks its being pressed sometimes moves a drop around.
When I downgrade back to 4.4.2 however the problem disappears. I've tried multiple 4.4.3 roms, and even tried running the 4.4.3 RUU, yet the issue persists. What could possibly be the problem. Could it be hardware related? In which case why does it only show on 4.4.3?
I really need to fix this, and will offer a bounty of $10 to anyone who will work with me to try to figure out what exactly the issue is, and fix it. I can send videos and logcats if need be.
Bump. I could really use help with this issue...
The second problems happens to me too
Sometimes when I open the gmail app, an email is pressed on its own without me touching the screen.
This happened a lot of times.
Has anyone else encountered this?
Weird... Are you running a custom kernel?

Good question.
I'm on HTC stock 2.22.401.4 and didn't encounter this problems with the actual or predecessor firmwares. So it could either be a problem with the GPE 4.4.3 kernel, or caused by a custom kernel installed. The - as I think - only alternative is that one of the installed apps is causing issues ..
