[FIXED 11.10.2007]Major hardware keyboard issues

Hi again,
so i recently fixed my keyboard issue and to lighten up darkness: it was not a software-issue.
after playing with the thought of returning the phone to tmobile, i flashed the "new official" tmobile-DE rom, and the tmobile service center told me, that this would void my warranty because the rom hasn't been downloaded from the offical tmobile-DE website... so i discarded the option of returning the phone in the next few month
toda i woke up and retried my hardware-keyboard on the vario 2, i recognized something which was: the reason for the vario dropping so much keypresses, was a bad contactivity... i mean: i can hear the key i press "clicking" but no char appeared on the screen... so i disassembled the vario 2 todays morning, and searched for a way to fix this, a way to give the keyboard a better fitting, or somewhat like that. the difficultest thing was to remove the "void"-label without tearing it... took me about 15 minutes to remove this damn label, but it remained intact
after that, i systematically disassembled the phone, and i did the following things to the keyboard-parts:
removed the white label which was on the "contact-side" of the keyboard-circuit
realligned this label and put it back on the circuit
then i put the keys and the circuit back into the housing, and got a piece of paper
i cut this to be as long an high as the circuit itself is, and put 3 of those paper-sheets onto the back of the keyboard-circuit, then fixed the 3 sheets a little with the flex-cable connecting the keyboard to the main-circuit.
then put the phone back together an tested it
my keyboards working like a charm right now, i'm so happy that my phones completely working again, without returning it
i thought this might help someone who has got same problems, perhaps my keyboard got this malfunction after the first drop, i do not remember when this problem occured the first time, and actually... i don't have to anymore

this is the orignal post said:
hellow to all
so i'm using my hermes (MDA Vario II) for as much as two months now.
I dropped it two times, first time 20cm onto carpet, second time 40cm onto the street -.-
but as far as i can see, not much damage, some scratches, nothing to worry about.
since i have this phone, i flashed several roms onto it. Black/Faria/Schaps/t-mobile_shipped/dopod wm6/black wm6 final/and many others... even some of my own roms got tested in there
i wasn't able to test the shipped status for very long, because i flashed the first custom rom about five days after hardware-arrival
the one thing driving me insane at the moment is the f**king hardware-keyboard. sometimes the "red dot" (for the second assignment of the keys) gets locked, without me wanting this. or i press "space" and nothing happens, or even worse, it adds some crazy special symbols to my sms wich then extends to four or more sms...
the e and w keys sometimes do not respond, and worst case ever had: keyboards gets fully locked up... had to soft-reset.
during the testing of the many custom roms, which were pre-finals, (in contrast to wm6-release versions), i thought: "yes everythings working, and the keyboard driver is producing crap". but even with the dopod rom (wm6) now active on my hermes, i have problems described above.
may it be the 1.50 radio? should i go back to 1.47?
or is it an hardware issue? should i return the phone to my loval mobilcom-store?
its driving me insane, i have to recheck every word two times... and i have to correct many things... actually i'm typing very fast, and this lowers my typing speed by, lets say 2000%
looking forward to hear your ideas,
will be grateful for every idea, which gets me some closer to a solution...
greetings
and keep up all your good work

There can be software issues that cause freezing and perhaps laggy behaviour on the keyboard. However, from what you describe, I tend to think it's primarily a hardware issue. (Possibly made worse or even more annoying by software slow downs for unrelated reasons.
If having used different ROMs, key behaviour is still largely the same (eg the same keys respond poorly or require harder presses) then I suggest you have the not uncommon hardware keyboard issue:

If changing ROMs leads to varying issues with the key board, but the behaviour of the keys changes ie different keys cause problems then it could either be software or the keyboard ribbon cable is poorly connected.

thanks for the link,
actually i thought about disassembling my hermes, but then again thought about warranty because its just 2 months of age...
i'll test the keys some more, especially the space, e, w, and "reddot" seem malfunctional... will keep an eye on the keys, and if original WM5 rom does not help, i will reflash the phone to factory default, and return the phone to my nearest store... they will have a solution and if it will be a replacement i'll be happy with it either
greetings
garfield

hi @ all...
sorry for digging this thread out
but recently i recognized my keyboard to be malfunctional again.
with "again" i mean, i thought it worked quite good for some time (lets say a month or so) but for some tome now, i assume 3weeks now, my keyboard throws the same annoying malfuntions as it had done the time i opened this thread. perhaps i ignored them for a while, so i haven't recognized the malfunction, but maybe my phone was really "cured" for some time.
Note: i've been running on the official dopod wm6 rom all the time since i opened this thread. WM% and WM5 original didn't help me, so i decided to stick to WM6. i've just tried 3 different roms, and two pandora self-cooked-roms in the last hour, and tested my keybard very much.
but it seems to be faulty... it lags some keys (in fact "reddot", e, w, space, colon (as a result of the reddot hang) and sometimes i get the "reddot" locked with only pressing it a single time. three words later i recognize that i am writing crap
so... any remainig ideas? or should i return it back to t-mobile?
i tried wm5/6 several roms
also tried various radios, at the moment running on 1.54...
if i want to return it, what do i have to look out for? should i flash it back to original t_mob_101_shipped_rom? and should i restore the original SPL?
i've simunlocked the phone... but did'nt SUPERCID it... always used the Hard-SPL 2.10. Is there any way to bring my phone into a state in which it would be possible and safe to return it?
greetings
garfield

fixed my problem (see first post)

keyboard button problem (not symbols)

I was wondering if anyone else is having problems with individual keys wearing out on the 6800. Three of my keys have become a little difficult to use. When I press them they act as if they have not been pressed. I have to press the many times before they will work.
I've tried googling but the only problem people seem to be having is the "symbol problem". My problem is different from this - it is a mechanical problem. The phone is only 6 months old and I use it regularly but not excessively.
I'm thought about taking the phone apart to see if there is anything that I can do.

I have the exact same issue, mostly with the space bar... some keys would take pushing it several before it works or sometimes I would press the key once and I get two letters, for example if I press E once I get EE.
Let me know if you find a solution for this, it's extremely annoying.

sounds like normal wear and tear to me. if you use a button alot, eventually its going to start working less efficiently than it used to. there are a bunch of good (free) full screen keyboards that you can use to give your keyboard a rest. taking apart your phone is a really bad idea. if you've only had it for 6 months, its still under 1 yr manufacturer warranty. send it in and get a new one.

thanks so much for the quick response, this might be a stupid question, but how do I exchange my phone? It's a Sprint Mogul.

probably the most direct way is to head into a Sprint store. and try your best to talk to them like you know what youre talking about, so they dont try to jerk you around. when i was using the xv6700, i got 9.. yes 9 replacement phones on my manufacturers warranty. if there is nothing to show that YOU have damaged the keys, they have to replace the phone for you.

try this, it fixed my key misses and repeats, but i have to hit the keys a bit harder.

Unfortunately, 'titan_key.cab' does not fix my problem

Thanks for the file...unfortunately, the problem persists on my Mogul.
Has anyone found a solution that makes the hardware keyboard perform as it did BEFORE the last official ROM upgrade was released into the wild. Installation of that [allegedly] tested and approved HTC/Sprint file coincided with my beginning to experience my KB problems.
HELP?!

Titan Keyboard failing

some keys i have to press super hard, other keys i tap and it types the key like 3 times
like when i press a
it types
aaa
and im like wha?
i am still under warranty, should i just put original stock rom back on and ask them to repair it or try and get it switched out for a vogue 0.o

I have a similar problem on my device. Is this a known problem?

Ditto here, the Function key has to be pressed hard, and some keys in the first row are acting up as well, but primarily the Q key.

I'm not sure that this has been officially acknowledged by HTC or any providers but it seems to be a widespread issue for end users.
While the "hard presses" for Function, Q and P seem to be a physical problem many users have reported that using the following CAB fixes the duplicate entries.

This is deff a problem. My phone does the exact same thing as OP.
I press a and it types it three times. This is the only key that this happens on.

I didn't realize how bad the keyboard was degrading until yesterday, when my Mogul was replaced. For me, the ./0, y/1 and function key were the worst offenders. The unit was swapped because the usb port broke. The port failed because it's a really cheap design, 2 pins broke off . The rep in the repair center insinuated that it was a really common issue, she didn't even look at the port when I explained the problem. On the plus side,I got rid of the dreaded white spot and my keyboard works well again, but for how long? The keyboard, screen and usb port problems are all common complaints on this board and others. What I surmise from this is that HTC makes a pretty crappy product! When this phone is retired in a year or so, I'm hopeful that I'll be able to replace it with a non HTC/non Windows Mobile (or whatever MS calls it next). Every time I use my phone, I wonder if it be wonderfully helpful tool this time, or a frustrating pain in the ass? Unfortunately, the later happens all too often!

These cabs dont necessarily fix the hardware keyboard issues. It fixes the old issues of the function button always being on in certain applications.
The issues that people are having is just wear and tear. The XV6800 has a cheap build.

hi guys,
same here, when i type "a" either doesnt do anything or it gives me a duplicate of 3 a's. and that started happening since i upgraded to dcd 3.2.0 an on.
also when i switch to landscape mode it sometimes writes an H or Y or P. don't know if it is OS related or hardware but it is a brand new phone and i never recall having this before going to dcds greatest 3.2.X.
edit: also i've been using quickmenu ever since 3.2.0 because of the x-button issue so i was thinking is any of you using quickmenu too?

fn key problem
So I guess many people have this "hard press fn key" issue. Annoys me a lot, especially with password sites where I cannot see the entry. Would this justify replacement from spring, i have full insurance?

I don't really think it's a hardware degradation issue. This is because there is no gradual degradation. If it were I would think just a few keys would start acting this way and then eventually a bunch of them would. With me I just all of a sudden noticed one day that all my keys were acting wonky. I think it was after a ROM flash but I can't recall any specific one that broke it (I change the ROM more often than I use my keyboard I think haha).
The CAB seems to help a little. I still have to take more care in typing than I used to but it's better than having so many repetitions of the same key.

I still say it's a hardware thing. Because if it was the software / ROM you would just be able to hard reset and your keyboard would be back to the state it was before.
My keyboard has issues with the E,O,H,Function Key, Space Bar, and the L.
It's something we will have to live with or just return our phones for a new one and wait for that one to wear out.
Just like the spots on the screen, loose stylus and so on. The 6800 was a bad build for HTC.

I Did Not Typs0r That! I Did Not Typs0r That!
ya well. it is definitely hardware. spoke to 4 co-workers with same company issued phone. one of them still has the stock rom on it, lol.. anyway
all now reporting this same issue.
i mean i was able to use my keyboard 2 months ago, and now i can't at all. its like i have a fat vogue minus 64 megs of ram. i mean i really got used to just using the on screen one.
i gotta figure out how to get stock rom back on so i can bring it to verizon and demand... satisfaction! only prob is nochem said something about it bricking your phone after putting radio 3.39 on it

Hmmm.... anyone go back to an older rom to see if this resolves it. if it does, i must throw away everything i know about electronics.

My gift to the WORLD!
keyboard fixed.
wow it was the software.
i built a rom without the htc diamond keyboard and it works fine now.
wtf? but im happy, keyboard is working normally

hummm... I have problems with the "Q" and the left softkey, I have to press them hard...

keyboard failing on Telus P4000
I got the same problem with my Telus P4000..
I think this is how I ran into this problem ...
I had radio 3.39 and dcd 3.1.2 at the time ...
I then decided to upgrade to radio 3.42.30 and another OS ROM (version I dont quite recall.)
That is when I ran into this issue with the keyboard.
So I went back to dcd 3.1.2 (kept 3.42.30 radio)
Same problem.
So i decided to revert back to stock ROM on TELUS (2.13) and radio 1.32
Still having this issue... I hope I do not have to bring in my phone to have it repaired. It will be the second time I bring it in

Flashed yesterday to DCD3.2.3 which uses the same keyboard driver as 2.1.4 (according to the changelog).
My keyboard was wonky as hell before this flash unless I installed the fix and even with the fix it would sometimes mess up. With the new ROM (and old driver) my keyboard works almost flawlessly without the fix installed.
Still everyone thinks it's hardware-related but it definitely showed up all of a sudden with a flash months ago and it disappeared just as quickly (for me anyway).
If you have keyboard issues maybe try the new ROM and see if you have a successful fix like I did.

definitely software, i should make a youtube vid to show it.
loaded up the stock rom to bring back to verizon to return saying keyboard was all quirky and i was standing there and everything was fine. im like what the hell?
what the hell brah?
ok so here is the instructions that fixed it for me:
restored stock rom
tested keyboard to see it working fine
flash it with the newer roms with radio 3.39
everything seems fine.
i can't explain it but it works.

my Problem possibly due to environment fluctuations: Heat-Cold-Humidity

Ok... after I went back to TELUS stock, i then proceeded to flash up to dcd's latest at the time: 3.2.3 with 3.42.30 radio. Keyboard issue was still there ... So.. where to go from here right ...
Well, I recalled that I began having this issue not long after flashing 3.42.30 RADIO i think it was initially. If i recall correctly, it was not immediate. I left to go camping for 4 days and my battery died .. So I left the phone off for most of those 4 days. When I got back from camping, that is where the keyboard issue began. Note: It did not get wet, but it obviously gets damp at night. My thought: phone off for extended amount of time in damp environment, somehow affected the keyboard. I don't know how, maybe some sort of rusting of sorts due to the hot/cold/humid fluctuations inside the tent (estimated environmental fluctuations>15-30 celsius with 60-90%RH). Reason I say this is the following:
I decided to pass my fingers accross the keyboard on every buttoms back and forth with a decent amount of force. Idea being that I could maybe create enough friction or force to disrupt whatever is causing the issue under my keyboard .. I did that for a bit. And my keyboard is working better. Not perfect, but I would say 90%. I barely notice it now ..

Thanks for bringing this thread up. I have beeen getting a few missed keys, and in particular, the Fn key has been flaky. Either not working or double pressing so the Fn light comes on and locks.
So, when I heard others having the same issue, a short while back I sprayed the keyboard with contact cleaner. All better now. Now the typing mistakes are all my fault, not the keyboard.
If you try this, use a plastic safe cleaner. I used Caig Pro Gold.

universal going crazy on me! keeps dialling and doing weird things!

Hi, recently my SPV M5000 has been really acting weird. it was fine using WM5 official rom, then i upgraded it to luca's wm6.1 rom, and it was still fine. then a month or two later it started behaving weird. in apps such as word, typing on the keyboard brings up the phone app, and when left alone it suddenly starts dialling numbers (the last number dialled)
i flashed it to tomal's 6.1 rom, and its still doing the same thing!! i'm at my wits end right now. could it be the bootloader or something? im using v2.06. i cant remember if i upgraded to it or if my device came with it.
thanks in advance

Try Doc format and reflash ROM

thanks for the reply, i just tried it but it dosent work
after checking it out some more, i realised most of the keys work fine, however its the h,n,j and u keys that are causing it to launch the phone app. Im not sure why it keeps trying to dial the last dialled number all by itself. i have to cancel it maybe 10 times before it stops trying.
the green "call" button on the spine of the phone also dosent work
could this be a hardware issue?

If if you tried the doc format and flashed other roms and the issue is still there it might be hardware problem...
and one thing just after flashing to new rom don't back up anything and see if the problem is still there.. if no then this bight be due to some applications in backup....
cheers
Rajiv...

sounds like hardware. you may have a sticky key. I'd take it to bits, give it a good clean and make sure the connectors are firmly pressed in - as concerns the spine keys and keyboard.

no, its not a sticky key. i guess its a loose/frayed connector
i'm reluctant to disassemble because of the form factor. guess i'll have to mothball it until i can get it repaired. i dont use it much anymore anyway, have since upgraded to a HD, but my girlfriend was using it as a mini laptop for word and skype when she didnt want to lug her laptop to college.
thanks anyway for the help

Is the screen intact? Is it clean around the edges? Did she spill coffee (cola?any drink?) on it? Is there any dirt around the screen where it meets the frame? Has it got a new screen protector installed recently?

Sounds like your hinge PCB got wet and is shorting.

Milestone 2 keyboard double-pressing - fix!

Has anyone encountered problems with the hardware keyboard on their Milestone 2 randomly entering two characters on a single stroke?
It happens at least once on nearly every sentence with mine, totally at random. I'm reasonably sure I don't suffer from any type of palsy. It's driving me batty.

Im quite sure the keys might need servicing. Its a problem that plagues many qwerty phones. I experienced it on my xperia x1 after 1.5 years of usage. Touch-wood no issues on my MS2 thus far.

I'm not sure what to think about the keyboard issue. On my xperia x1 the problem was obviously hardware wise but is it software wise on the Milestone 2?
Might be since I start every google search on my phone with a double letter while not having such problems in a started text...it seems like some sort of software lag causes this problem...
Can you guys confirm? What do you think?
Sent from my MotoA953 using XDA App

I do recognize this issue. I think it's a software issue, because sometimes a letter is repeated about 4 or 5 times, while I truly pressed the button once.
Other times I don't have any issues at all. But then again, I didn't hear or read anything about it, so I'll see. I'm not going to send it back to a repair center because I know how that works out.

i would dare say its nt some kind of software issue or bug. and its quite impossible for it to be a lag on a phone with a 1GHz chip and 512MB RAM. besides, i haven't really heard anybody else have the issue as you do.
i genuinely do believe its nothing more than a faulty button/buttons. i know the X1 suffered from this. so did the HTC Touch Pro, and the Touch Pro 2. it wont hurt anyway to take it back to the dealer/factory to have it checked up. you are entitled to a warranty and have every right to claim for it.

I can't believe nobody @ Motorola noticed that bug. In the first year of studying we learned how to debounce buttons.

kindly explain what 'debouncing buttons' means please?
also i hardly doubt its a bug. i think its a problem with the keyboard itself, as is the problem with many phones with a physical QWERTY

Ok, I'll try to explain. Imagine a button with a long distance from "not pressed" to "pressed", like an old Keyboard for example.
Now imagine pressing a button in slow motion. If the metal connectors of the button and the one below the button slowly approach each other, there are moments when the connectors almost "meet" and current flows. One nanosecond later the current isn't there anymore and another nanosecond later its there again. This process continues until youve fully pressed the button down.
But you don't want the letter do appear twice or more! So you've got to make sure that only one letter appears by telling the device, to only print 1 letter in the time, a normal user needs to press a key fully down.
LoL, i hope you can understand what I meant, I can't explain it that good in english

I understood your explanation, thank-you. I'm still going with soft-ware issues, though.
I encounter this problem every single time I type in the first letter of the first word in the google search. This can't be an accident.
Quote: and its quite impossible for it to be a lag on a phone with a 1GHz chip and 512MB RAM
Well, it is possible that a program (in my case the native internet explorer) lags. Also little lags in other programs may occur, when the load something for a millisecond. It may as well be both, hardware and software...

I encounter the Problem everytime i use the Keypad. My understanding of the problem as a debouncing-mistake makes me think of general software issue - on the other hand the problem is more frequent (but not exclusive) with letters on the right half of the keyboard , what seems like a hardware Problem.
I think there are variances in the keyboard assembly, so that the software debouncing works for some keyboards (and/or some regions of the keyboard) and for some it doesnt. So its basically a hardware Problem which could be solved by software tweaking.
Well, lets see what Motorola comes up with in the next update.

See if they come up with an update you mean
Sorry for spam but this company has strategies unexplainable to me...if they give us a upgrade I wont say a word bout them anymore. If they ignore us to death this was my last Moto.

well i actually kinda understood what u were on about. thanks i personally haven't experienced any such problems with my phone YET. of course...the phone is still new (4-5 months old) so i doubt there will be any problems. as i said i highly doubt its a software issue. so give it probably a year and im almost quite certain that the keyboard will start faltering

I'd have to agree with people saying it's a software issue.. it happens MORE on some keys, but it can happen on just about all of them and it's so random.
I find that if I press a key more forcefully and hold it down longer, the chances of it happening are greatly reduced. Something's definitely amiss with their timing.
Glad to see it's not just me!

No problems with keyboard. Maybe its just your finger? =P

I'm also going to throw my hat in for software. I noticed that sometimes when I entered a solitary capitalized I, it would enter the single I, but as soon as I hit space, it would add a second capital I onto the first one, then the space. No idea what could cause a bug like that though.
In addition, I did a hard reset about 2 weeks ago, and haven't had a single double-entry since.

I found that the issue is fixed in Argen2stone

I have the same problem as you with my french ms2. It doesnt have nothing to do especially with google but more with every external app on the net. I have the same problem on firefox.
And it doesnt have nothing do with the keyboard too since every keys are affected.

Even if it's a hardware problem, some software tweaking would solve that, as Rduke just explained. You just need to tell the software to only accept the 1st signal, the remaining being ignored.
And I'm sorry to say, but Argen2Stone doesn't remove the problem. Yes, it makes the phone a lot more responsive and fast, but the problem still exist. Maybe it'll get solved with 2.2.2 (Argen2Stone is 2.2.2 =D)
