hi im having a problem with my desire z keyboard. some keys such as O, P and S are not working well. like i have to press them really hard to bring the letter on the screen. the hardware touch is fine like the keys feel normal when i press them but with some 4 5 keys, the letter doesnt come up unless i press really hard. anyone else having such a problem and solutionss?
I am having the same problem, but I've kinda got used to the on-screen keyboard anyways.
Same problem here, and for another 3 people on Polish forum said about this too. I have send my DZ on warranty - waiting for answer. I have rooted ulocked and changed rom so I am curious about what they will say :> Depending on how much people have this problem it's a hidden defect for DZ not caused by user.
I have problems with my "a,s,d, and spacebar". Too bad that my Desire Z's warranty is already expired. Agree with the other poster, best way around it is to get use to the touch screen keyboard.

My DZ keyboard had been working perfect until recently.
The 'i' key and space key need to be pressed hard to register. But for the i key, sometimes if I press it hard enough, it will register twice. I think it is related to dirt/dust getting into the key or aging issue. And since my DZ is nearly two years old, I am not complaining. Anyone tried to take their phone apart and clean or replace the keyboard?
As i said before, I have send my phone to HTC Service with this problem and yesterday I got it back.
My phone was rooted and "htcdev unlocked" with Virtuous Sense ROM on board when I sended it and... there was no problem with it . They replaced "FPC Pre-Assy Qwerty" and didn't even restore orginal OS. Keyboard is working perfect.
Im having problems with my . button, no more warranty, so i guess i just have to live with it...
Have you attempted to shift to a different ROM? I had encountered certain hindrances akin to this whilst utilizing certain beta ROMs. Upgrading the ROM had solved this. Alternatively, it may be a hardware malfunction.
have the same problem as yashif,o,p,i,u need to press harder sometimes it register the key twice is it a hardware problem?

Sounds like dirty contacts in the keys. the proper way to fix this is to carefully disassemble and clean the keyboard parts with some diluted isopropyl alcohol.
The _improper_, _unsafe_ _lazy_ method that does not require disassembly but is probably a stupid thing to so (but I've done with success on another phone, not a Desire Z), is to remove the battery, spray a bunch of DILUTED rubbing alcohol onto the keyboard, saturating it so that it runs into the nooks and crannies, then repeatedly press the buttons up and down -- with the idea that some alcohol gets into the contacts and cleans them. Let the phone dry completely for 24 hours, put the battery back in and hope it turns on, then hope the keyboard works again.
Let me stress that I would only do this with a phone that is past warranty and that you wouldn't mine if it never works again...
Hey guys.
Late response but I happened across this thread when I was having this problem for a few days. I slowly realized after reinstalling my ROM with no joy, that I'd actually experienced this problem before, back when I'd taken the phone apart to replace the screen. Back then it turned out i'd left the keyboard ribbon cable loose which was causing some of the keys not to work.
Well it appears this time I may have knocked the cable out of place after dropping the phone (I do that alot) as after opening the phone, taking the cable out and then simply popping it back in, my ketyboard was back in working order!
If anyone is unsure about opening up the phone and trying, it's simply the first 3 minutes of the below video, upto removing the ribbon cable (just take it out and pop it back in, easy!)

DONT spray a bunch of DILUTED rubbing alcohol onto the keyboard
sorry for digging old threads but i had this problem and i thought someone will have it in the future

The phone is too well made it has 3 layers until u get to the contacts
and is 95% probable you hard brick your phone
Dust CANT get to the contacts, instead the problem comes from the metal part touching the contacts that is bent overtime.
these things look like a ( and when they are pressed they go like this | and in the middle of them you will see

I do not know if somebody faced this problems before or not:
1- The soft-keys, dial key, call drop key, and the scrolling keys; are always while pressing them for long time does not response until turning off the screen by pressing the power button then turning on again to keep working for awhile then same thing happen again.
2- The screen is sometimes fade to be completely white & brightness more, and everything hidden until turning off the screen by pressing the power button then turning on it again
If anybody knows how to fix this matter please provide me with the solution.
Thanks for all concerned
I had the same exact problem... I fixed it by getting a warranty exchange from AT&T!
I have the same problem! Unfortunately my phone is not covered by warranty. I think it's a hardware issue because I changed a number of ROMs and the problem persisted. I don't know what to do, it's driving me nuts!
Help anybody???
Good news!
Ok, as far as the key problem goes, using the PDF file about HTC TyTN where you can see how EXACTLY to disassemble and assemble the TyTN I took the courage to open up my TyTN and pull up the motherboard and clean everything up and close it tightly back. However I did not completely disassembled it as the manual shows because I did not want to remove any stuff that's glued like the rubber parts and the metal tape that holds the keyboard connector. So basically, I did not reach the part where the soft keys are, but somehow miraculously my keys are working nice again! I guess the problem was just loose connections and probably it was loosing contact somewhere because keys worked sometimes and then suddenly stopped.
Anyways, it's been 2 days now and the keys work perfectly and my TyTN is not so loose like it's going to fall apart as it was before!
P.S.
I haven't noticed the white screen problem also but it's been only 2 days and it wasn't happening so often before anyways.
This issue is known -there are threads in hermes section, search for white screen..
Its a harware issue with XILINX coolrunner(if I remember it right) on the front keypad below screen.. It propably has some bad solders under it -mine went so bad that it showed only white screen until I disassemled the unit and pressed directly the chip with my fingers
Then I bought a new circuit from cnn -at the moment it had those boards for sale, not anymore. That fixed my problem.
Among the threads someone got his/her phone to operate again by putting something between the cover and the chip..
I had the problem on my handset and managed to fix it by cutting up a piece of card..be it and old credit card or whatever to the size of the recess that the chip fits in...this pushes against it nicely and since then only had the problem reoccur once...then it was cured by just putting the handset into standby mode and back to normal again
Don't know if anyone else is experiencing this with their Play but as of a week or two ago the backlight started acting strange. The backlight will randomly stay off when I push the power button with the slider gamepad closed. Only way to make it come on is to pop out the slider. It seems to be random, and if I push on the slider edge slightly with my thumb with the slider closed the backlight randomly flickers, ranging from slight to severe.
The display is still working despite the backlight issues, I can open apps, and use the phone normally but the backlight flickers on and off. Makes it especially hard to use the phone in the dark.
Phone has never been dropped once.
I've replicated this problem with a variety of roms, both custom and stock. It's definitely not app related or even custom kernel related. It happens on a fresh wipe with stock rom with stock kernel. It happens on CM7 with custom kernel.
I'm curious if anybody else is experiencing this. It would tell me if it's just an isolated incident or if others are having this problem.
Sounds like a faulty connection to the backlight to me.
I had the same problem 2 days ago. Then I couldn't get my phone screen on at all!
I sent my phone back to Sony, even thought I bought it second hand. Phoned them up and talked to them. They asked what time of year I bought it so I said around August and then they gave me the address to send it to. Now I'm just waiting to see what happens next.
If your going to send your phone to Sony for repair then make sure you put the fresh firmware back on and un-root your phone as that breaks the warranty (unless they don't know about it)
Hope I helped you. If I did then click the thanks button
Sounds like a faulty ribbon cable to me. (cable that connects the screen to the rest of the phone)
You wouldn't need to drop it for that to go bad, It could just be a case of opening and closing the gamepad or lot.
Yeah good thoughts, most likely the ribbon. That really sucks because I've only had the phone for 7 months, and I've taken excellent care of it. Sounds like a major design oversight.
Mine is probably near complete failure at this point. It's taking a lot more effort to keep the screen on now. Fearing soon it won't work at all.
In hopes that this might help someone else down the line, I was able to fix my problem. Yesterday the screen pretty much quit and I had no choice but to try and solve it myself or buy a new phone.
Using this disassembly video as a visual aid I carefully pulled my phone apart: http://www.youtube.com/watch?v=-3n5ZfkqhzE
You'll need a torx T5 tool to pull out all the screws but they are cheap.
Underneath the phone and jammed into the screen ribbon was a rather thick hair just hanging out. Somehow it buried itself in there. I removed it, unplugged and replugged the screen ribbon and cleaned the dusty inside with a q-tip and reassembled it all together.
It works fine now, so hopefully this helps someone else avoid having to pony up for a new phone. For those under warranty probably best to send back but for those like me with no warranty it's worth the shot.
hey there guys and girls,
This is my first post and was just wondering about my xperia plays touchscreen. I bought it almost a year ago and since i got it the problem has been occuring. Its not major dont get me wrong but it can be really annoying when i am texting my frineds. What happens is that i will press a letter then it will just decide to press a bunch if other letters next to them. Also the keyboard will randomly go down so ill end up clicking send and completely wasting a text.
Any help would be great... Thanks xD
Large fingers? lets hope its not a digitizer problem but you did state its been happening since you got the phone. the xperia play does seem to me to be more sensitive to the amount of pressure needed or not needed; or is it just me?
Got used to using swype keyboard on my sgs and haven't used the stock keyboard on the play.
you could try to clear data for the keyboard Settings>Applications>Manage Applications>All>"keyboard"
maybe another keyboard will solve your problem entirely, there are plenty of them on the market/store.
this is just one as there are many
https://play.google.com/store/apps/...xLDEsImNvbS52bGx3cC5pbnB1dG1ldGhvZC5sYXRpbiJd
edit: forgot to mention, if you install this or any other input method you will first need to enable it in Settings>Language & keyboard>"keyboard"
just tick the box next to the keyboard and it will give you a prompt; read>OK
then say in messaging just press and hold on the text input field and select input method>select keyboard you want to use
also, when your keyboard disappears for whatever reason or doesn't show when needed you can press and hold the menu button for a few seconds to bring your keyboard up or make it go away.
I pulled off the screen protector and that seemed to fix it for me.
i've been having the exact same problem, it seems to occur mostly when my phone is charging or when it's too warm. Didn't bother sending it back though, but yes, it can be verry annoying when trying to text
Don't worry, its a standard Sony Ericsson issue. Usually occurs when the device overheats.
Reboot or look into ROM flashing and the problem will be resolved

Mine does that when there's moisture on the screen, or when plugged into the charger. I've found typing to be much less annoying in wet conditions when using Swype.
Dry off your screen often enough and it should help. Removing the anti-shatter film (which is next to useless anyway) also makes a difference.

Welcome to XDA!
Try solutions posted above.
If You ever need to test any piece of hardware on your phone, try accesing serice menu by typing this code in Dialler:
*#*#7378423#*#*
From there You can access Service tests menu and test Your Touch Screen/Earphone/Display just to mention a few.
Also screen protector isn't any good for me, standard keyboard is too small and stock firmware is to laggy to type messages. Solution is easy if You are ready to give your phone a boost by flashing it as mentioned by someone else above.
Wow, there is a great amount of different anwsers
I remember that someone on these forums said that Xplay has problems with multitouch regonizing (or something)
Basicly, the touch points wont reset unless you do something (i dont remember what)
Personaly, i just press powerbutto to "shut down" my screen, press main menu butto and open the lock, its all back to normal
EDIT: wait few seconds (like 5 or so) before you reopen the screen
i'm having a similiar problem, i charged my phone with 5v a couple times, so the last week, the touchscreen doesn't work. sometimes it does, it has been abit tricky. it like works sometimes, with an effort of constantly mashing the screen (with swipes and presses), but the last 24 hours, it's been practically dead. every other part of the phone works, like LED, pad controls, speaker, etc etc, just touchscreen is dead... any solution, methods?

Honestly, I have no idea. I just know that the digitizer is what makes the touch screen work, and that there have been xda users buying them for replacement parts before.

I have been getting this problem when coming in from outside. I can hold my finger about 1cm above the touchscreen and it will type random letters as well. Seems to be affected worse in bottom left hand corner for me. It settles back down after a while of being indoors. Its really weird though.

That's because the difference in temperature and humidity causes condensation to gather on the screen, temporarily. Capacitive touch screens work by conducting electricity, and moisture is conductive.

My Desire Z had a fall, and has developed two problems
1 - The hardware keypad has started to take hard-press and sometimes prints double characters on single press. I think the alignment is out or something... any other guess ?
2 - The touch screen sometimes stops working from an inch up from the bottom and continues to half an inch. Before and after that patch, the touch always works fine . Mostly, the whole touch screen works fine. But when the patch gets non-responsive, I have observed that by turning the screen off and on a couple of times makes it work again. I am not very sure what the problem is. Any clues ?
Thanks
I'm also experiencing a similar issue - for me it's usually an area that corresponds to the top row of the
on-screen keypad (for unlocking) or the top of the area for unlock patterns (portrait orientation).
Mine is a 2 year old DZ w. Cyanogenmod 7.1
No HW key problems & no droppage.
Liberal application of isopropyl alcohol and a microfiber cloth - especially around the edges of the screen
seem to help a little bit but not often enough to be better than random.
Switching the screen off and on occasionally helps but most often I get annoyed and use the HW keys to
unlock.
I have noticed that, after powering on the device, the SIM-lock keypad works just fine but the (different)
screen-unlock keypad fails. This leads me to believe it to be a software issue.

Thread moved to Q & A section.
So i am going for Digitizer replacement will post the result when the phone is back.
And what about the Keypad taking hardpresses ? what can be the issue there ?
so my desire z is in the shop for repairs. lets see what problem is diagnosed.
I have read in another thread in this forum that the hardware keyboard (need to press hard on some buttons) issue can happen when the phone falls.
Apparently, the flat cable that connects the keyboard to the rest of the phone gets loose and causes such trouble.
Since your phone is in for repair, I'm sure this will get sorted when U get it back.
ok so my phone got back from repairs, the guy couldnt fix the touch-screen rather made it worse. Now the touchscreen doesnt work at all. So i cant unlock the phone and cannot test the Keyboard problem. The guy said the touch problem is related to the ribbon cable and not the touchscreen itself.
Note 1: He says he tried replacing the touch panel altogether but it didnt work.
Note 2: I still think the ribbon is fine (call it intuition)
Note 3: I am giving my phone for repairs again, but this time to HTC service center which would probably cost me a lot more than third-party repairs but at least it will get fixed.
I will update when I my phone back from HTC service center.
Could you not unlock the phone by opening the keyboard ?
It does smell to be an issue with flat (ribbon) cable to me as well. As if there was some loose contact before (caused by you dropping it), and after the repair guy took the phone apart, he probably made even bigger mess by ruining the flat cable completely.
From my experience (and I've claimed warranty 3x for the broken digitizer (touch panel)), if it's broken, an area of the screen (or the whole screen) will be permanently dead. It would not come back to life every now and then.
btw, mine always started being unresponsive in the very middle of the screen, a bar of height around 1 cm (somewhat less than 1/2 inch). Each time they replaced the digitizer.
If it;s the flat cable, you shouldn't end up being charged too much - those thingies are very cheap (in China) and the labour will probably be the majority of the price. Fingers crossed.
So I got my phone back again... The HTC repair center was not located in my city so I went to another (better known) repair shop. The guy said, "your phone hasnt been opened at all from the touchscreen side, any *repair guy* who claims he has opened it and tried this and that but couldnt fix is simply lying. This said, he opened up my desire z replaced its Touch Panel and voilah! my desire z is sensing again in 15 mins
What's the status for the keypad and need to press it hard to work ?
nope... I had it cleaned using alcohol / thinner. now it works fine.
So, I updated to CM 7.2 last night but the touchscreen problems are still there.
Updated using CWM and deleted data & cache whilst doing so.
I really hate the prospect of getting a new phone as the current models available
in DK are all without physical keyboards
Its been some days, I'm experiencing this weird touch screen problem.
My DZ touch screen doesn't respond properly.
For example:
If i see an image and slide just one finger up and down then it would zoom in and out. And then the whole screen becomes unresponsive.
It seems as if, its touched by itself. Even the softkeys would go numb. Only the haptic feedback of my search button works at that moment.
But the trackpad works perfectly.
But, If i lock and unlock the screen using power buttons, it would work properly for some few moment and then again the problem repeats.
At present I'm repeating this process of locking and unlocking screen to use my phone.
One even worst weird thing is that, if the device is connected to a charger and kept on the table or floor. This problem doesn't occur.
I have done system format, restored my nandroids and even changed Roms. The problem still exists.
Please note, i don't use any Casing or covers that would press the device hard for malfunctioning of screen. I have even removed and replaced my screen guard.
I'm sure, its not a software issue.
And even i dont think its a strip issue, because i dont use my physical keyboard always.
Can anyone say what hardware issue it might be..?
Or what i need to do? I'm really out of options.
Do i have to replace my whole screen or the digitizer..?
Thanks...
Thats no fun,
As you stated it's more than likely a hardware fault, the two most likely culprits would be the digitizer or the main flex cable
Which would be this and this
both relatively easy to replace depending on your experience
in 4.x and up ROMs check the developers setting to show touch or use apps like
z device test
or
yet another multitouch test
these wont help you fix the issue but may show you where the bad points are on the screen
best of luck
I know the problematic spot. Its near Search softkey. Even Yet another multi-touch test would stuck at that spot....
As you can see in the image, that i'm not holding anywhere, still it shows that somewhere around Search softkey its touched by itself.
In second image, If i move my fingers around, it would show the other touch responds, but if i slide near search, it would go and stuck there itself.
So, i guess i would first go with the flex cable.
In actuality I'm leaning toward the digitizer in your case, but its possible to be either.
And if you have a spare phone it may be worth disassembling even without buying anything. On a G1 I once fixed a similar issue just taking out the digitizer and cleaning the contacts on the ribbon and the edges of it as well, when I put it back it worked like new. I think some dust may have gotten into the edges but it may be worth a shot before buying anything... But could make matters worse so if you don't have a spare, buy parts first
Best of luck

I guess i should try disassembling and clean it first. If it still persists then i would go for digitizer.
And thanks for giving a hope.
