u/2 button pressing itself.. wat the hell

the u/2 button stopped working and starts randomly pressing itself every time i turn it on... and it randomly presses itself during texting as well and the u/2 button doesnt work its kinda getting annoying now.... can any one help or have any suggestions on what to do.... thanks

any ideas?

u/2 ...? What is that...?

It's probably similar to what happened to my Toshiba laptop. I'd get a pattern of letters/symbols when typing on it, because the case/keyboard screws were too tight and it spontaneously would generate these signals. I'd bet something smacked your keyboard or it was pressed too hard and something broke inside.
It's probably not user repairable, at least not easily, and probably a warranty workable item. Flash back to the stock ROM and send it in, especially if this only occurs when using the slider keyboard.
Hope it helps, even if it is bad news.

the u button on the keyboard.... and i dont have warrenty on it because i bought it off ebay and i live in canada its a tmobile phone. theres no way i can fix it? like it presses itself when i turn the screen on and sometimes when im writing texts.... but the actual "u" button doesnt work when pressed

It can be fixed, but I don't think it will be easy. That is, if it is similar to what I am thinking. If you're daring, or desperate, you can try disassembling the unit to see if something is cut or pinched, causing a short.
Is anyone here familiar with the hardware side of this unit?

I think it doesnt make a good contact with the mainboard.
If you press the button, does it feel different then other buttons..?
Otherwise it could be alot of things but the best thing to do is to take it to your carrier store.
Maybe they could do something for you.

nope the button feels just like any other button when i turn off the screen and turn it on it dials 2 a few times... and when i text sometimes the u button repedetly comes on the screen.... =( its so annoying

So many hardware issues

It first started with the blue light blinking, even with the phone turned off. The only way to stop it from blinking was to remove the battery for about 10 seconds.
Then, everything I typed staarted to ddoublle letteers raandomlyy.
Now, it's acting like the down button is stuck. I can't do anything on the phone because its always scrolling down, beating out any other input.
I can live with the first two, but the third one has made the phone completely unusable. It's never been around water, never dropped, just randomly doing this crap. Any ideas on how to fix it? Hard reset does not work, new rom does not work, its a hardware issue.

Yes it is probably a hardware issue. Time for a phone swap

I'm actually out of warranty, so the only thing I can do it either switch to a different phone or try fixing this one. Have nothing to lose by opening it up, just wanted to see if anyone else has fixed it by cutting any wires or connections on the inside of the phone.

You don't have insurance

No phone insurance. Verizon completely screwed me on that phone purchase in more ways than one. By the time I figured that out it was to late.

TO bad I got mine added late. I just called the lady I bought the phone from and she added it.

Not sure about the blue-light.
I was able to fix my repeating-letters using the keyboard fix in this post:
For the constant-down input - it could either be the touchscreen digitizer or the hardware keyboard. YouTube has a series of videos on dismantling the Mogul - it may be worth some "exploratory surgery" to see what might be causing the problem (cookie crumbs, perhaps)...
Hope this helps. Good luck.

Htc mogul hardware button - issue
Dear XDA GURUS,
I am facing this very weird problem on my HTC MOGUL. All my Hardware button have stopped responding / Working. Please help me sort out this issue.
Waiting for your valued reply with solution.
Detail given on below link.
My HTC MOGUL HARDWARE Button Issue

Dear XDA GURUS,
yesterday i tried to do some RnD for this same problem. now the inputs. (Nothing technical)
* Even though my camera hardware button is not working, but, i can still enter the bootloader screen.
* Even though my both soft reset hardware button are not working, but, still i can do the hard reset.
This only means that, my buttons are working fine, but, according to my logic, they have lost there assignment.
After that i started searching web, if i can find a App / setting / hack / register setting, in which i can assign then there original key setting. So i found this on XDA forum as below.
Code:
[B]How to assign a shortcut to EndKey, SendKey, Power Button, PTT Button!![/B]
Hello
Since some of you guys asked about this , well there you go:
if you look inside the keyboard driver with a good disassembler (IDA Pro) you would see that you can create these link files :
Long_PTT.lnk (push to talk button+long press)
Long_End.lnk (the read key+long press)
Long_Send.lnk (the green key+long press)
Short_PTT.lnk (push to talk button)
Long_Power.lnk (Power button +long press)
Short_Power.lnk (Power button)
So basically all you need is to create these link files and put them in to windows folder. You can assign these keys to any shortcut you want .

ok now, certain things are clear. now anybody out there can help get this thing sorted out.
Waiting for concrete solution.

Hardware buttons

Having installed android just recently on my hd2, I started to use my hardware buttons more often. Now, whenever I push the windows-flag-button on the far left (still the button but close to its left rim), then the home-button is pushed too. Is this a general flaw of the hardware buttons or is it just my hd2. I would love to see some response, in order to see whether it makes any sense to send it in or to just live with it.
Thanks in advance!!

After I changed to the "Photon" style and use, I started using the hardware buttons extensively - that was already last summer.
Did never have any issue like you describe. Still everything working perfect for me.

I have the same issue with my HD2 (also using an Android NAND). I believe, that it is a hardware-flaw, and not a ROM-Issue. I just made myself press more on the right of that button (closer to the middle of these two buttons (Flag and Back-button)) , and now it doesn't really bother me anymore.
I hope, I could help.

BTW: I own a O2 HD2 from Germany. (Might, that this flaw is connected to a specific model)

The hardware buttons begin failing on a lot of hd2s, this is a common problem since android makes you use hardware buttons more. There are several threads about it. Luckily, a dev from this forum created button savior for android, an app that creates soft buttons on the side of your screen that can pull out when you need them. Get Button Savior from the market... a needed app for the hd2 so you don't have to use your hardware buttons so much.

Just in case you don't know: there's a software alternative for hardware buttons on Android, SW Key.

Edit: oops sorry, previous poster also pointed you towards that. Well, here's the link ;-)

try not to use your nail to click on the key,, use the middle of your fingers to push slowly down.

My HD2 is about year old. I bought it (months 4 ago) with broken digitizer. Replaced it itself. What i finded inside is interesting. Buttons bar have clued some small plastic dots (see on pic). As i understand they fits to keypad excrescent plastic dots (dont have pic). And one of these on buttons bar was gone. I ordered then new button bar and now no more problems with buttons. Before i had too problems when i pushed home button accidently popped up calling or menu (windows logo button pressed).
Hope this helped you find right direction to resolve your problem.

Sorry, maybe the question was phrased incorrectly.
my home button has failed. in ASOP builds my phone boots into safemode.
in Sense builds it doesnt, but my battery ussage in both types of builds is above 50 ma
can I turn off the buttons to sort out the short in the rom.

Thanks for your response!!
I have sent it in for repair and got a 100% cash refund.
Well, let's see what little gadget I can buy for the money ...

The Infamous Unresponsive Digitizier Screen Possibly Solved!

Okay I wasnt going to post about this cause there have been way too many posts and alot of back and forth and debates and even flaming, but I stumbled across something that I think is the cause for MAJORITY of the issues with why we keep having this happen. It Happened to me Today, and I Found the cause.
Before ANYONE Flames me for bringing this up, READ the post, Remember I solved the cause of why it happens to most of us, I dont take responsibility if you choose to take it upon yourself to fix it! And I know 90% of the users are going to tell me I'm wrong or I dont know what I am talking about, so be it.
If you have nothing to add other then flaming the post, just hit the back button and be on your merry way and pretend you never saw it. But I am 98% sure I am right about why its happening!
So if your interested read on:
I actually for the first time had this, and I know this is going to get flamed but its not the Screen thats the problem. And I think (BIG IF) that the dreaded unresponsive screen issue that we keep reading about Majority of them I think is not the screen.
I have 2 HD2s and both have worked flawlessly without any problems, but today I was playing with my test phone that doesnt get used that much and I noticed after installing a new rom that my screen after I played with it for a bit went black (sleep) and when I woke it up it wouldnt respond, first thing that crossed my mind is I just lost my digitizier, and started wondering okay why, I went as far to re-flash WinMo stock HD2 rom, same issue, so I decided its time to find out exactly whats causing this, and I found it. I wasnt going to make a post again cause I figured people would be "Not another thread about this" but I know whats causing the screen issue, at least this is my suspicision and I have temporarily fixed mine.
The problem is HARDWARE, The Culprit: THE END KEY (Red Button)! The Answer to "How or Why": The "End" key is used to turn the phone on and off or to put it in sleep mode, it is the most used key out of all 5 keys, it is used probably 7x more then all the rest, Its used for just about everything, now how does this cause the unresponsive screen? Easy, the phone lock or sleep is associated with this key, Its the only way to make the screen go off other then waiting for the time out period. Because by habit we mostly hit the end key to turn the screen off the phone automatically associates this with locking the phone, once that happens the screen becomes unresponsive because of several reasons: 1) The contact under the actual key has dirt which causes the button to stick in the down position, 2) the contact is bent which the "end" key is pressing down on the contact which is making contact with the board and causing it to be unresponsive, 3) The contact is worn. This is the reason why if you press the end key a few times (anywhere between 2-10) and then try the screen responds, this is cause your "unsticking" the key which then lets the screen respond.
Most of us when we hit the end key press to the far right to avoid hitting the back key (The button with the left arrow) which causes the end button to lean toward the right. But you can wake the phone up with the other 4 keys to the lock screen which will allow you to unlock the phone. As a temporary fix for myself, on my test phone I now make sure to press on the left side of the key to prevent this from happening, since its a test phone I'm not worried, but the real solution is to take the phone apart and clean the underside of the end button, and the actual contact with alcohol to remove the build up of dirt and whatever else. And also if the contact frame is bent to GENTLY bend the right side back up alittle to stop it from happening, or sending it to htc and letting them fix it.
We have to RE-TRAIN ourselves to start using the other keys to wake the phone up and not rely on the end key so much.
Hope this helps anyone finally why we have this problem. And if it works for you then hit the Thanks button

I completely agree with you. I've had the "dead digitizer" since December. It was pretty apparent it was a hardware key problem, as I could generally solve the issue by pressing the "Off" button to turn the screen off, and then one of the other keys (usually the back button, but occasionally one of the others) to wake the screen up, and the digitizer would be alive again.
As I am still under warranty, I sent mine off last week, and expect to hear back within a few days. But if I had the confidence to open it myself, I was sure it would be fixed with a good clean.
Anyway, thanks for crystallizing all this into a post. Thanked!

THANK YOU SO MUCH FOR THE INFO. i have had so much trouble with unresponsive screen after installing typhoon 2.6.3 and it from holding down the red button all the time for install and the past millions times for everything else.

Thanks for the heads up

U maybe be right about why this issue happens but if u rely on other key then will also wear out soon ...
What I did is I remapped my volume up n down keys to power and back button which I believe are the most used in android and then found a app to manage my volume in android that way I don't lose my sound on rhw phone
Also I went ahead and got a another app which places virtual buttons on ur screen so u can use then instead of the actual hardware buttons
For button remapping
get the BUTTONREMAPPER for android and for on screen android buttons get BUTTON SAVIOR
hope this helps

Good to know... will now wake my phone up with the green key as its hardly used in Android. Button Savior is a great app, been using it a while now. Took a bit to retrain myself to not use the back key.

i'm going to agree with your hypothesis or at least suspect that dirt is probably a bigger factor than most people think in these cases. i just bought a non-responsive phone today and while i stuck my nail (yes, i should probably clip them) around the edge, in between the screen and housing, i was surprised to see just how much dirt was in between that crack. same with the area around the buttons; there's a lot of grime there.
since i just got the phone i haven't even opened it up but the first thing i'm planning to do is give it a good interior clean around the buttons for sure as that seems to be the sensitive spot. touch screen devices are very delicate and the micro particles of dirt which build up over time probably create a hazard that people really don't really anticipate. compound that with having to mash on those buttons all the time probably crams the debris in there even tighter.
i'll attempt to clean and check the contact as you suggested and will report back if it helped in my case.

About hardware keys:
I don't use them at all, only for wake up the phone (it can be wake up with any key)
There is an app in market called "button saviour" it's just excellent app to keep your hardware keys for a long time

You just hit d nail on d head pal...My HD2's touchscreen also stopped responding and nothing i did (software-wise) worked...i flashed several WinMo ROMs and Android builds with no luck, till i read somewhere online dat some guy seemed 2 solve his touchscreen issues by installing "CleanRam", ran a level 3 clean up (use MyMobiler for this) and by pressing real hard on the red end key button..I did just dat and voila it works!!
I have a Tmobile HD2 which is no longer covered under warranty and i'm not willing 2 part with almost $200 here 2 have d whole lcd & digitizer replaced...I recollected dat in d forum i read the suggestion from, a lot of ppl came n posed their views on why it's not possible but i tell u it is cuz it worked for me..Nw i'm comfortably dual-booting WinMo & Android via sd. i use "button savior" and "extended control" to navigate and power down/reboot respectively.
Hweva i believe its not a permanent fix as it simply refuses 2 allow me run android full-time thru MAGLDR, & i think i know y..pressing down on d end button 2 launch MAGLDR/CWR options after install messes up d connection with d digitizer underneath and d touch screen thereby causing it 2 fail again when android boots up....I just might try opening it up myself n cleaning dat area up as u suggest but dat'll be when my current fix fails cuz as d saying goes "If it aint broken? then don't fix it"

Just installed Button Remapper, and not to sound like an idiot, but can someone tell me which one I would have to remap to make the volume up key or down key to put the phone to sleep and wake it up, and would that still be able to use the volume key to turn up and down the volume as well?

Hmm...i don't use d app but from wat i can gather on d dev's thread, you would have 2 remap ur volume keys to "Power"...Also checkout dis review 2 learn hw 2 mk d remapped button work even in sleep-mode.

I can agree but mine's been in twice on repairs with the same error but screen was replaced both times amongst the digitizer, backcover (Can't understand why) and 3 other things were replaced. Buttons weren't replaced.

If I'm to base how the HD2 is setup internally, they wouldnt replace the buttons, they would replace the contact or contact board under the buttons, remember the buttons are like a keyboard, they dont wear out, its what they push on that gets dirty or worn.

I was traveling and this happen t me and became desperate.
Following the instructions I come to the clear conclusion that our HD2 has this hardware problem.
If I do not use the end call button no issues with the screen, really, no issues.
Hope my feedback will be helpfull as well. Great job done here!

Yeah HTC screwed up on dat...its just as said,1 has 2 be careful n avoid using d red end key button as much as possible 2 enable d device last much longer...And if u do ave 2 use it, press on d left-most part of d key (closer 2 d back arrow button) to get d job done.

I just had this issue happen to me and thought it was my build... But I found another way, I use Cyanogen Mod 7, and in the drag down menu (from the top) I added a sleep option, because thats the only thing I use it for... and I never have a reason to press the end button now.
This is the best thing I have found to fix it without having to remap the buttons

I guess I'm lucky because I have never had a problem with the responsiveness of the touchscreen and/or end button. I got my HD2 a month before TMO release date and trust me it has been thru alot (scratches all over, even a piece of glass missing next to the call button). So my question is how much pressure and wear 'n' tear are you all putting on your end button or phone for that matter?

It all depends really Understand that not all HD2's go thru the same testing process when it comes out of the manufacturer. Also take into consideration that it also depends on how often you flash a rom, if your flashing a rom every day or every week expect that you will shorten the life of the end button, also it doesnt always mean that the button is bad, it could clearly be dirt underneath that could also be causing the issue. And I said the same thing when I saw posts about people saying that android killed their screen. I even responded to it but always maintained it was hardware, even though I didn have the problem, and I bought both my HD2's used in Dec. and the day it happened and I found out why I posted this, if I was to guess, I would say that I probably flashed both my HD2's close to 200 times with different roms, or upgrades, or testing fixes out.
So if your not a flash nut, then your probably safe. There are many factors that can play a role in the end button life cycle, And no two people use their HD2's the exact same way.

the non-responsive touchscreen problem happened to me this morning. I woke up trying to unlock my phone only to find that it would not respond to any touch gestures. I was however able to uninstall HSPL and Flash the stock WM6.5 rom since I was going to T-Mobile to get a replacement. When I took it to T-Mobile the employee resetted the phone by holding the 2 volume buttons and the power button then somehow the touchscreen started to respond to touch again. I was completely puzzled as I thought it was for sure a hardware problem. But now I'm going to flash Android and hopefully the problem will not arise again, if it does, back to T-Mobile I'll go!

What Android really needs is some sort of "X" button, or even a widget on the main screen that you can just tap and put it to sleep. The three most keys used in my opinion is the windows key (Apps that use it for a menu), the back key (Since there is no damn close button), and the end key (sleep, flashing, booting to magdlr).
Some one had a concept here of buttons that looked very similar to The desire HD, the greatest thing would be if someone could make the bottom of the htc sense (app drawer, phone, and the personalize) auto hide and have the desire HD buttons come up with a power button at the end and this way if you hit menu it would bring up the original 3 button screen.

[Q] Best way to use HD2 without buttons? (hard buttons no longer work on my phone.)

So i've been dealing with this for the last week or so and I finally decided to stop searching and scouring the internet and ask for some help from my XDA brethren.
I don't exactly know how or why, but all the hard buttons on my HD2 do not work anymore. Volume up and down, pick up, home, menu, back, and hang up buttons... all not working. They all stopped working at the same time.
I don't really care except for the fact that I cannot wake my phone up after it locks/sleeps. I tried an app called Shake and Wake with no luck. Any sugguestions? or should I just look for a new phone? I really don't want to give up on my HD2... we've been through a lot! Thanks a ton you guys, I really appreciate it.

If I were you I would head on over to the nexus one threads and ask the question.
That phone only has one button, and some folk have had that not work, so they are used to the problem, and I'm sure they will have a solution for you. Worth a try anyway........

Button Savior - free from Market

Jadrobe, I really like button saviour but that still doesn't solve my problem, how do I wake the phone up without any buttons?!!

do your volume buttons work? if so, you could use ButtonRemapper (paid app) to remap one of your volume buttons to work as your power button and do the rest with button savior.

Nope, none of the buttons work!! I'm screwed!

Then yes, you are indeed screwed. Sorry for your misfortune.

Pretty much. If you have one working button then you could use an app called "button remapper"

Have you flashed back to stock/something different yet? Seems a touch coincidental that they all go at once. The bottom 5, or the two volume yea, cos they're on two separate input busses, but for both to fail together... not saying it couldn't happen, just saying it could be something else.

If there not working how do you turn on your phone?

When I slide the battery into the phone it automatically boots up as if I pushed in the power button.. it never used to do that before.
And also right after it powers up it sends me straight to slide to shut down which kind of makes me believe I may have the power button stuck on or something? I'm going to try to flash the stock rom and see what happens. I'll keep you all posted. Thanks!

Dude!! Proximity Screen Off (look in Abdroid Themes and Apps sub-forum) could fix you up in combination with button savior !
It has an option to use the prox sensor to put your phone to sleep and to wake it. The downside is it will drain your battery faster than normal because the prox sensor is in use when the screen's off. But it could keep your phone useable til you can get your buttons fixed (probly just your power button is malfunctioning it sounds like to me)

Thanks a ton Huggs. I'll definitely look into it, as the main reason I love this phone is for Android roms!
So far i've had good luck with this Winmo 6.5 app. I had to revert to the base/stock Tmo rom and it works okay.
