I am sure someone has the answer for this.
The "touch" part of my touchscreen has become less responsive. I have to bare down in order to get the screen to accept touch inputs. Anyone know how to adjust this?
Thanks
It really seems like there should be a registry edit for this like there is on the touch pro, does anyone know what it is?
I cant seem to find the posts I was looking for, but it seems that the titan was hardware limited when it came to changing screen sensitivity. I remember it being discussed in old threads but none of the registry mods, i.e. adding reg keys or changing reg keys did anything.
I could very well be wrong as this is speculation until I find those posts I remember reading a long time ago. I will keep looking too...
I appreciate it.
I wonder what I could do then to regain the functionality. It was working just fine until about 3 weeks ago and it now requires a much firmer touch.
Align, Soft Reset, Hard Reset, Connections, Replace Screen?
I doubt this will help but just some thoughts. I don't suppose any of these may help but they are simple enough, well not so much the hard reset if you don't have a good backup solution.
Try going Start > Settings > System > Screen > Align Screen and tapping lightly to calibrate screen for lighter input.
Try a soft reset.
Backup you data and programs and try a hard reset.
Open up your case and check the connections and mounting of the screen. You just need a some small flat head screw drivers, a clean surface. A small plastic guitar pic helps for separating the case. Tweezers help if you have relative large hands. You could even just swap in a new screen. You may want to buy some of that special tape to hold a new screen in.
Here is a cab with my screen calibration just in case it helps.
Do you have anything that adds functionality to touches such as FTouchFloSL installed? Those can occasionally have unintended consequences. Try disabling or uninstalling them.

I have soft reset, hard reset, even installed a new rom. Every time I did the above I had to calibrate the screen, which is very, very, very difficult being that I have to bare down so hard.
Since I have a TP now I may try taking it apart. If I need to replace the screen, does anyone know where I could get one?

nothing special installed, but I have had them in the past.
I have had sensitivity issues with my titan ever since I have owned it. I had a spot in the screencenter of the top half that would take several seconds of holding the stylus on it to get an input.
I have tried to recalibrate several hundred times with very light touches, and it never seemed to help a bit. hard resets didn't help at all either. God forbid putting a screen protector on it, as it would render it useless.
I recently found a replacement "Touch screen digitizer" on eBay for less than $20, compared to $60+ for a replacement lcd and touch screen assembly. I was rather nervous about disassembling the touchscreen assembly, although I have taken the screen out of my phone a few times to try and find a secret gremlin causing the trouble. All in all, a razor blade to cut through the adhesive and taking the metal casing off the LCD to get at the very small connector for the touch panel was the most difficult part. It only took about a half hour and three beers of courage. Now it works better than ever before.
If you are electromechanically inept, I wouldn't suggest this fix, as it isn't just bolting in a new part. It does involve intricate work. There were a couple times I thought, "OH S%$#!" and I routinely take things like this apart. So try it at your own risk.

The touchscreen on my titan is acting very problematically, with the screen slowly getting more and more inaccurate to touchscreen inputs, it's getting to the point where i have to use align screen 3+ times per day, and it's incredibly upsetting, is there any fix for this, or is it a hardware problem?
I'm not sure what it is but I too had that problem. After I flashed to DCD's 3.0.1 ROM,, the screen seems to be more stable. I still have to align screen every now and then. Do you you use your finger instead of the stylus? Sounds weird but I do that a lot and that might contribute to the problem.
Yeah, I do use my fingers on the screen a bit, with PointUI's Home, I don't see how that could cause it though o.o.
My I760 did that on two different phones. So i just got the xv6800, no problems yet except the ****ty video drivers-Or lack there of.
Okay, at this point the screen is going nuts, I'm probably going to have to send it off to sprint for a replacement at this point, as within 20 seconds of aligning the screen it's off by a good 5mm, and that number keeps rising.
Is you screen dirty? Along with using my fingers, my screen was dirty also. I just used a dry towel and clean the screen by blowing hot breath on it. Also, I bought new screen protectors. Yes it does seem odd that using my stylus and having a clean screen helped with my problem. Maybe my new ROM fixed the problem, I don't know. But its not as bad as it was before. Good luck.
Yeah, my problem was getting exponentially worse, off by about 6mm or so every time I'd align the screen, so I just returned it on my insurance plan.
Stylus vs Finger
If you are aligning your screen using the stylus and then using your finger for gestures and such the screen response is not aligned. You have to align with your finger in order to get a more accurate response because your finger covers so much more area than that tiny stylus tip.
I would alternate back and forth between the two, but to give an example of how severe the problem was getting, I would align the screen (with stylus) launch a program, and -already- the screen would respond about 4-5 millimeters down and 2-3 millimeters to the right of the stylus, which would make various tasks nigh-impossible.
I had the same issue and notice that it was mainly due to the fact that my screen was dirty as mentioned before. Sometimes you may even notice that your screen may not be dirty but remember that oils from our fingers and especially our ears when we talk can cause the alignment issues. Perhaps you can even change the screen protector and see if this helps. This should fix all of your issues assuming it is not an actual software problem. The one time that I did find the alignment to be a software issue, all I had to do to fix it was to callibrate the screen in both standard and panoramic view. I hope this helps...
Nah, it wasn't that, I tried cleaning off the screen with a microfiber cleaning cloth and everything, even removed the screen protector to see if that was causing it, it was a hardware defect.
Well I can say this.. I used to work for Sprint, Nextell, Verison, and ATT at various points. I know that with more of them, they usually send you out another device and you send your back. The think I love about ATT is that they will do this with a No Questions Asked policy except for the standard one involving abuse, water damage ect. After 3 defective devices, they will automatically upgrade you to another device.... Please make sure that the reasons are lagitimate so that this policy does not change but if you need to go through the hoops to get a better device that works.... Have at it. Do not take it to a store unless directed by the telephone people. Many people feel like they are techs because they own a ppc of some sort but they are not the ones that make the ultimate call. Let the corperate people make the decisions. Once you receive your device, immediately stress test it with all of the things that you will be doing with your device. Load and unload software, ect to make sure it works. If ther eis an issue, it ie better to notify them within the first 72 hours. I hope this helps again.
Well, the touchscreen just doesn't respond both fingers or stylus.
Have no idea what could had caused the problem.
It seems that everything else is alright, w/hardware keyboard out image turns landscape...just doesn't respond to touches.
Should I return my phone?
Is it a warranty case?
Has anybody experienced anything similar?
Do you have a screen protector on your screen? If yes, try removing it (You can put it back afterwards). I have experienced this very problem. Another attempt is a Hardreset. If none of that helps, go for warranty.
Well, there wasn't a screen protector and I already tried hard reset - still, no response. I tried flashing a number of ROMs, they installed, but can't use 'em - since I can't finish "screen calibration"...
I guess it just shows that the problem is a hardware one.

Most definitely. It can be a problem with statics, maybe this can help you a little bit further. Also try touching in the corners of the screen (REALLY in the corners). Then go for warranty.
Well, thanks a lot!
Phone's being serviced, gonna take sometime for sure...
I've got this three times now - and it somehow worked again after a day or two. It happend always after I was cleaning the screen.
So my first thougt was, that a little bit of the window cleaner I used went into the device and short-circuit something. And when this drop of cleaning liquid dries, everything works normal. Makes sense, but that wasn't the problem.
At the third time, I discovered, that sometimes when I touched the non-reacting screen, the startmenu opens. Which made me recognize, that there must be something in the very upper left corner always "pressing" the screen. And so it was: With a brush (those which comes with an electric shaver) I was able to remove a noteworthy amount of dust/dirt. After that the screen instantly works fine.
A friend of mine brought me his Wing to look at for him. If I turn on the phone on it boots up and the screen looks just fine. When I slide the screen opened to use the keyboard the screen freezes and when I close it again it gets all jumbled up. There are lines going through it and I can not make out anything. The phone isn't locking up at this point because I can press menu buttons and other hard buttons and see the screen react, I just can't tell what is happening.
I assume that this is a hardware problem. I was thinking that the cable that connects the screen may have been jarred loose or damaged in some way. If that is the case do you think that it would be as easy as opening it up and repositioning the cable? I don't have any experience with this phone specifically so I don't know if this is a common issue.
I was also wondering if it is possible that this is just a software issue. Maybe the function that rotates the screen for use with the keyboard is messing up and jumbling the horizontal and veritcal lines when going back and forth. I was thinking about doing a hard reset and seeing if this clears up anything. Any thoughts?
I appreciate any help. This forum has always been there when I needed help in the past. I'm sure somebody out there has much more experience and knowledge that I have and can lead me in the right direction.
Thanks for any and all help!!
Update...
So I went ahead and tried the hard reset first hoping that it might be a software issue. I am now at the screen that says "Tap screen to setup your Windows Mobile based device." No screen touches are being recognized. This seems to support my thoughts that there is a loose cable or bad connection. Agree?
I just slid the screen opened to see what would happen and it faded to white.
Yep, if my experience with the Wizard tells me anything, the flex cable from the main body of the phone to the screen is either loose or damaged somehow. Even a small nick or cut into the flex cable will cause it to stop working correctly. I would hunt up the Herald service manual and take your device apart and see what you can find.
Thanks ... I downloaded the service manual and plan on taking it apart. I have to make a run to the store though and buy a small enough Tork screw driver. T5 or T6 I believe.
Thanks again, I will post with my findings when I get going on it.
now what?
So ... I have the phone completely torn apart. I do not see any loose or damaged cables. It was dirty inside the phone but other than that everything looks just fine.
Does anybody have any advice as for things to look for, that might be causing this problem, while I have this thing torn apart?
Guys I did some search job today and have a possible final solution to the back button problem.
Luckily this is also in the forum posted by user ID:insaneturbo13
his thread is here:
http://forum.xda-developers.com/showthread.php?t=833663
He is a Samsung Captivate user, right. Since I think if nexus s have met with is annoying problem, other samsung phones may either. So I did some search job in bed with my insensitive-back-button Nexus S, and found the Epic 4G, Samsung Focus, Captivate, etc. Almost all samsung phones got users annoyed by the problem.
Then I searched the Youtube to see if there is any Samsung user had ever achieved some success in solving the issue, and I found.(You won't know how terrible it is when you have to use a U.S VPN just to watch Youtube since it is blocked in here China mainland... really slow speed...together with facebook and twitter...ToT)
My understanding to the cause is: The picture of the back button is a thin line with an arrow, so the inside paint here may over-cover this thin line, which will definitely make the touch action less sensitive. And that's why there are less people got such problem with the other three keys.
And since capacitive buttons actually respond with the obvious temperature difference, so many frustrated nexus s users like me found under warmer environment the problem is less annoying...
Maybe this is only workable for insensitive problem. But hopefully this is a way.
Since I am a Chinese, it's impossible for me to have an exchange with the Bestbuy. So this is my only solution. But for most of you, it's highly recommended to take several exchanges before you definitely want to try this way.
Of course, try this at your own risk
what i did was tighten up the screws on the back of the phone... especially in the lower part of the phone. I haven't seen the issue since and initially it was a pretty often issue for me.

I think this is also a good way to solve the problem especially when you dont have to take to phone apart~
The theory may be the same, which is to make the distance between your touch and the module inside shorter cuz there is a piece of rubber under the button position so it can be possible~~
Thanks for sharing this way Dude~~~

how did you access the screws at the bottom to tighten them?
Take off the battery cover. You have 6 bright screws around the edges of the phone. Tighten those up.
Sent from my Nexus S using XDA App
Although, I know this is not gonna help, but it comes from personal experience.
In the beginning, I used to be haunted by the silly back button "bizarre".
I factory reset the phone then voila. It's gone.
The reason I am confident to post this is, my brother's phone was fixed in
a same way as well. I know, I can be just lucky, but I just wanted to share.

thanks, I decided to watch the video on how to take apart the phone this morning, didn't do it, but it covered the screw access for the hidden 2 screws.
tightened the screws what little bit I could without fear of breaking something (they were already pretty tight), but it made no noticable difference.
I actually got my phone a few days before they were launched (friend is at&t store manager), so I 've been living with it as long as they have been available. it's annoying, and did get a little better with froyo, but not bad enough for me to tear apart the phone and risk damage to the screen...

there are no hidden or covered screws and the phone doesn't need to be taken apart.
look here: http://guide-images.ifixit.net/igi/BJtxWYS4NMaMyMKL.medium
these are the 6 screws
Mine just started this thing where it presses the back button by itself. Pretty anoying and is making the phone useless. I can't do anything without it just hammering on the back button.
hi everyone,
i'm new to this forum, and joined to see if anyone has been successful in fixing the back button issue...
i've followed some of the advice from previous posts (tightening screws, reset factory settings, updating the OS) but still no luck.
hoping that someone might have discovered a fix (apart from returing the device!) they could share.
thanks!
-----------------------------------------------------------------------------------------------------------
hi everyone,
After posting the thread above, I updated OS to 2.3.3 and now back button is working fine.... I waited for a couple of weeks before confirming this, so hopefully anyone still waiting on a fix could try what I did. This seems to be a software problem more than anything else...
btw - 2.3.3 noticeably washes out colours, and there's a yellow/green tinge to white space. awful.

Hi
I did the same and the problem has gone - just realised after reading your post that factory reset solved this problem.
My phone is constantly on 3G but whenever it dips into Edge or has a weak data signal I notice the back button issue as well. And I tried a factory reset but it did
not fix the problem on 2.3.3
Back button issue
There are a few longer threads in this forum about the back button issue on the Nexus S -- for some people the back button doesn't work at all, and for others it turns on all by itself. There were a few replies from a Google employee (ryguy) who said it would be fixed in an upcoming OTA update, etc. but some reported having problems AFTER getting 2.3.2 when the problem didn't exist before. There are also other reports of tightening the screws on the back of the phone, which haven't tried but seemed to improve things for people whose back button WASN'T working at all.
For my phone around 2-3 weeks after buying it I had the back button come on all by itself. I fixed it by doing hard resets, as suggested on an earlier thread that deals with this issue (it's like 10 pages long but has the complete story of everyone's experience and fixes with this issue). Anyway, the point is for me after the first hard reset the problem persisted, so I did it a few more times (like maybe 5 times) and now it's gone.
There are some people who tried a hard reset (factory settings restore) and the problem still persists but I think that you have to do as many hard resets as possible (like, over and over and over) until the problem disappears. I'm rooted so I did a Nandroid backup first, then did 5 hard resets through Clockwork Recovery (select the "Wipe User Data" option), and after five hard resets I just flashed by backup and I was back to where I was, minus the back button issue. You don't have to be rooted, of course, to do this, but if you are, doing that ROM Manager backup allows you to quickly reinstall everything to the exact way it was after you're done with the five or 10 hard resets or whatever.
If you're unrooted you can power off the phone, then turn it on while holding the Up Volume button. This boots you into Bootloader mode and you can navigate around to do a factory reset. Or, if you are rooted and have ROM manager, you can use ClockworkMod Recovery like I did (see other threads on how to use these programs).
Anyway, again for me I had to do a bunch of these hard resets to fix the problem, so if it persists after the first two resets, I think you have to keep doing it until it disappears. Hope this helps - TC

i think mine is forever beat. 15 hard resets and its still there.
My apologies for bumping such an old thread... But i got a captivate to serve as a backup phone, and i slapped over ICS on to it..
Everything was super awesome.... BUT! not the Back button.
A few minutes of google'ing later, im here.
So after reading through this thread, and the one linked to in the OP, i opened up my Phone and ....well....went on with it.

Some Tips :
1: Once your down to the frame with the LCD assembly stuck to it, first remove the Antenna Module. Under that disconnect the black ribbon connector. (This ribbon connects the capacitive button module to the main board).
2: Before starting to Pry apart the LCD from the frame, take a hair dryer and heat up the edges of the LCD Assembly's frame. This helps a freaking lot in prying it apart. Plus it somewhat preserves the 3M adhesive tape present underneath, and can easily be reused.
3: Start prying open the LCD, from the Ear piece side. Take your time and DO NOT!! And i freaking mean, DO NOT!!!!! rush through while removing the LCD assembly.
4: When your almost half way through (or slightly more , but significantly above the capacitive buttons) take a peak between the frame and the LCD assembly, youll see the "Bridging/Connecting" ribbon i mentioned earlier and it might be stuck to the LCD's back.
-> the best way to proceed further is to simultaneously heat up the "glued" parts and slowly continue with removing the LCD. This way, the glue will not stick to the whatever parts it is meant to stick to , THAT strongly and will be much easier to remove.
5: Now as soon as you reach the part where you can see the Capacitive button module sticking to the LCD assembly, go into SUPER FREAKING SLOW mode... THE RIBBON UNDERNEATH IS VERY VERY FRAGILE! ONE YANK AND YOU'LL HAVE TO PURCHASE A NEW CAPACITIVE MODULE.
*Best way to do this is, to again simultaneously heat the concerned parts while slowing pulling the LCD assembly and the capacitive button module apart.*
You can try going LEFT-RIGHT-LEFT-RIGHT alternatively, to slowly make the adhesive give away.
6: After you have the LCD assembly out, its pretty much dependent on how stable yours hands are at slowly etching out the Light gray parts.
-> You can hold the LCD assembly against a TABLE LAMP / some light source, to better see which parts of paint you need to etch out. *i Almost etched the whole of my back button* So be very careful and gentle as well PATIENT!
Before assembling the LCD back into the frame, i took a small piece of paper (about the size of the capacitive button module) and stuck it between the frame and the module. Just so that it makes better contact with the LCD assembly.
7: Stick the LCD back onto the frame and again heat up the edges. Also while putting the LCD back together, make sure the adhesive tape has not lumped up on any of the edges (This might have happened while trying to pry the LCD out) , if it has, then just gently even/flatten it out. Stick the LCD back and heat the edges. Rest, just take a soft cloth and squeeze the LCD's edges and frame together,so as to make sure they stick together properly. The heat really helps in bonding things here.
Assemble back the phone, blah blah.
I used a CREDIT CARD to start prying the LCD away from the frame. It was pretty easy, because of the heat.
DO THIS AT YOUR OWN RISK! I AM NOT RESPONSIBLE IF YOU SOMEHOW MANGE TO MESS UP YOUR PHONE! Specifically the LCD and the CAPACITVE TOUCH MODULE!
Big thanks to the OP for posting this.
Hi all,
My trusty blackstone has begin letting me down and I don't know if flashing a new rom will help, or if it is something physical that is breaking / broken. I'm using the Stonehenge ROM with CHT and everything has been fine for months.
Recently the touch screen allignment just seems to 'wander' sometimes just a little, other times quite a lot (so much that using the fake hardware buttons at the bottom of the phone, brings up the start menu). This means that intermittently I cannot answer calls, and typing a message on the SIP is an absolute nightmare!
The start menu icons do not seem to be as affected as the home screen and CHT, and I can quite easily get to the phone settings and recalibrate the screen - this will help for a short while but the alignment drifts again.
Restarting the phone has a temporary positive effect but it doesn't last.
Anyone else experienced this?
I have exactly the same problem.
Dissembled the whole device, blown some hot air but didn't help. Seems it's a HW fault. But I have a doubt whether the problem is in digitizer or in control board.
It's definitely one of the more frustrating problems that I've ever had with the phone.
I might try flash a new ROM then give up if that doesn't work. At least I won't be tempted to disassemble as it has already been tried, tbh I'd have just tried the tin of compressed air too, I don't trust my soldering skills for tiny electronics.
It is getting progressively worse, the touch area of the screen has slipped so low now that I can't use half the screen.
