I just replaced a screen in a Trinity (Dopod D810). The touchscreen initially wasn't calibrated correctly so I ran the alignment tool in the settings, and after a few attempts, I calibrated it properly and the touchscreen was working perfectly. Now the touchscreen is not working properly. The top half of the screen responds to touch, but no matter where I press in that region, the screen thinks I'm pressing the top-right corner. When I run the alignment again, it responds to all the touchpoints but it never successfully calibrates and it keeps bringing me back to the alignment screen.
The current settings in the registry entry for touch calibration are as follows:
484,558 244,286 263,815 750,820 707,295
I've found a few other threads here (the most helpful being http://forum.xda-developers.com/showthread.php?t=355010) and I've tried the settings from that thread. The screen seems more responsive, but still not correct because the bottom half hardly responds and the top half seems to respond when it feels like it.
Can someone please post their D810 touchscreen settings so I can try it? I've tried the settings from my Touch Cruise, but the screen is still doing weird things.
This is a customer's phone so I need to have this fixed ASAP.
I'm thinking that it may be a faulty digitizer, but that won't explain why it worked perfectly when I first calibrated it.
UPDATE: NOT FIXED yet, but now the backlight is dead. I just turned it off, and then turned it on again, but I can only see the screen content if I shine a torch onto the screen. The LCD hasn't leaked. The backlight just died and the connectors in the phone are fine. Perhaps this was a dodgy screen.
Any ideas?!
since the device has a recessed screen, take the cover off to get at it.
take a soft cloth or something and clean off all the garbage on the digitizer and back of the plastic. make sure everything around the lcd is free of dirt.
usually, if there is something pushing down on the digitizer while you calibrate it, it will totally bork the alignment over the course of 10 minutes to an hour.
my kaiser is currently having this issue, though i put it though alot more hell then i should have... so i suspect its suffering from other issues.
Screen looks great. But I'm having two issues.
First, the screen feels kinda rough dragging my finger across. By comparison my Galaxy S phone and iPad are very smooth and glide with no resistance.
Is this normal, can it be improved?
Second, the screen seems unresponsive at times. I'll have to tap more than one to get it to recognize an action. Maybe it's just being slow.
Also the calibration seems to be a bit off. I often seem to be clicking items below what I tapped on. Not sure it's completely user error since I don't seem to be having this much trouble with my 4 inch Android phone.
PS. The phone is rooted with AutoNooter and using LauncherPro and Dolphin browser.

My screen is very smooth, and a little bit tacky... I'd prefer a less tacky, smoother feel, but it's okay.
Unresponsive I've not noticed really, but the calibration on the edges and/or corners is funky.. Like hitting the Search button in the market is hit and miss, otherwise other places I personally haven't seen any issues.
There's a thread on here / directions on nookdevs for how to recalibrate the screen. A lot of people have been reporting issues with the calibration on the edge of the screen. It doesn't bother me too much, so I haven't tried, but results are apparently quite good.
http://www.nookdevs.com/Recalibrate_the_NookColor_touch_screen
I've recalibrated the screen a few times. Even did the suggestion with placing the Nook face down for extreme sensitivity.
I still seem to be having the same problem where the touch is very unresponsive. It's most noticable browsing the web, I'll have to tap links multiple times before the browser does anything.
I'm wondering if I have a bad Nook or is this just how it is?
It could be the default browser. I had problems with unresponsive tapping as well but after switching to Dolphin Browser HD I havent really noticed them at all. However, it does seems like only certain apps or portions of them have problems with touch response...I can think of 2 off the top of my head..
1) The search icon in the Android Market. I have to really tap it hard or multiple times for it to open the search ability. Everything else in the market is a light, smooth, responsive tap, except the search ability.
2) ADW's settings menu, specifically the back button. Have to really hit it hard to work yet everything else works perfectly fine.
Maybe it's just me but I swear its only certain things which respond poorly to taps.
In regards to the screen being tacky, goto B&N and buy the Anti-Glare protective screen film. Make sure its the anti-glare one and not the regular screen protector. Not only will your fingers slide perfectly, but it also avoids all the annoying fingerprints the default glass seems to collect. Worth every penny. (You get 2 of them for 15 bucks)
I find that I have better luck ith a light touch & avoid a "tap". It took a bit of practice to know what part of my finger was actually making contact with the screen first & the reason for the perception that the screen was out of calibration.
I do have a problem with the center right area of the screen when playing crossword. Sometimes it is very hard to click on the rufgt side boxes. Interestingly, the same area of the screen is responsive in other apps.

I purchased the matte screen protector from them and it alleviated the tacky feel of the screen. Also resist oils and smudges so its a must have in my opinion.

I have the same problem at the very top edges of the screen. Pressing search in marketplace or a new tab in dolphin is really annoying. Requires many taps to work. Rest of screen seems to work fine. I did notice that the 2.2 Froyo was way worse for screen sensitivity. Maybe they can fix somehow with a firmware patch or something.
I have the same problem. Will try recalibrating later.

I don't think the market search button issue is a screen calibration issue. I initially thought there was an issue with the sensitivity/calibration in the top corner of the screen, but I have the same problem with market search when I am in portrait or landscape. Touching items in the same area of the screen in other apps is fine.
My screen is definitely more responsive after doing the commands.
I made sure to clean it completely with a microfiber cloth before running the commands.
As for the market search issue, it seems to have improved the sensitivity. In fact, to me it now feels as if I am getting the button push through, but it just takes time for the app to register it and take action (lag) and thus we think the button push did not go through and push it again...
my 2¢
A lot of the discussion on this thread is for locale based calibration, but I had the issue where if you hold still on a drag and drop, before dropping the thing you are holding is jittery, as thugh your finger was being jittery. This calibration fixed that problem.
Under the thought that this might happen again, would be nice if there was a way to run the command locally on the system without having to connect to adb to recalibrate.
Any ideas on how that could be done? I was thinking maybe scripted terminal commands?
I am not sure whether it is my mind playing trick with me or not, but I feel like my phone is less sensitive after I did the hard reset (power+volume down). Sometimes I need to press 2-3 times because the first light tap was not detected.
So is there anyway to increase the sensitivity?
I have the same problem, but no idea that is the hardware or only software problem.....
Fresh owner of this Optimus 2X in France, in our community, frandroid.com, we encounter the same problem , I think this is a software issue.
Did someone already contact LG??
Maybe they should include this into the bug list thread.
May I know were you guys having this problem since it is out of the box? or after reset?
I have the same problem started from day 1 till now
I have the same issue and already thought I'd be the only one having this problem.
I would not say it's a problem with sensitivity, but it feels like the touchscreen goes into some kind of sleepmode where then you need to press a second time, to wake it up.
Continuous touching is no problem. (like when typing rapidly on the keyboard)
This video is not from me, but it shows the problem.
Have a look at 13:28 and 13:37. The reviewer tries to hit the "Ackermann" entry, but the touchscreen does not recognize the touch. At 13:37 the guy has to press another time to get the entry selected.

Yes! The touchscreen is definitely less sensitive than my old HTC Hero, and gets quite frustrating sometimes when a scroll misses the first part of the movement or a click is missed.
Sent from my LG-P990 using XDA App
just in case, are you guys using 20110218 baseband too?
The same problem here. If I unlock the screen and then tap on any on screen apps, I need to touch again for it to open. Only the first time though, after that it function ok. I think this is a bug and needs to be fixed... I have my pc for double-click.
Yep, count me in. Same problem here. Sometimes screen taps aren't registered. Will do some research later on, but I think it's a software problem. (maybe you have to tap 2x as fast )
Hi,
same problem here!
Potentially a driver issue. A Nexus S user had a similar issue in this thread: http://forum.cyanogenmod.com/topic/18431-tuning-driver-to-deal-with-unresponsive-touchscreen/
He managed to tweak the driver and it works fine now. Need to know C++ (I think?) to understand though.

I see, then probably they will fix it on the next update/gingerbread?
Same issue here.
Correct me if I'm wrong, but the problem seems to be that the screen has zero tolerance when it comes to tapping and swiping together. If you tap and slide your finger a bit directly after the tap, the tap is ignored. In other words your tap has to be a steady tap when you click on a button or an app. Right on the spot and with no swiping or sliding afterwards. I can't reproduce this on any of my other devices.
Ergo, it seems that the natural tapping I'm used to isn't working on the x2. It seems like I have to adjust my tap. I think that this could in principle be solved with a setting somewhere, because clearly the x2 is capable of registering this in for example a web page.
The great thing of this is that you can safely tap and swipe in the app drawer to scroll up and down or left and right. The downside is that a tap with a little swipe isn't registered at all. I would say that LG has choosen here for a wrong setting.
My personal experience about screen sensivity.. can you confirm if it's the same for your device?
I noticed a strange touch response.. and after some tests, I can say that the touch screen and icons are influenced by the surface where the phone was put!
with the phone in my hands, it's all ok (only sometimes - rare - I need to tap more than once).
If I put the phone over a glass surface (like a glass table) without touching it with both hands, the touch and the icons not respond!! NEVER!
If I put the phone on my scanner the touch screen works ok, but the icons not (or only few and rare taps was detected).!
If I put the phone over my big Onkyo amplifier.. It works like in my hands.. or better!! even without touching with hands.. only with a finger!
Put it back on my glass table.. and all stop working again. If I put a aluminium foil under the phone (between phone and table).. the touch and the icons works again !!
If I put it on the bed.. it don't work.
LG support say that they have tested the phone about this issue after my report.. but no strange response was detected by them. I don't know if they really tested it..
Try it and let me know what you think about!
tested on glass surface, I can press and swipe through pages with a finger without problem.
it is true that my device is not so responsive, but aint reaching that level yet
i read about a similar behaviour on other devices because some devices need a proper grounding for the capacitive screen to work correctly. You can find this problem via google.
Some devices have problem in a car-mounting, for example.
But i think thats not the problem the thread-opener talked about?
Guys I'm looking to get this phone and after reading Engadgets review of the X2 where they mention that the screen is not as sensitive to the touch as other phones I got a bit worried and started googling which lead me here!
Is this true? The screen isn't very sensitive and you have to apply more pressure than other capacitive phones?
I know that the OP is talking about a different issue but I reckon LG will get that sorted out via software update, or at least hope so!
Please do post your experience about the screen sensitivity of the X2 as this is putting me off. I currently have the Motorola Milestone 2 which is very sensitive to the touch even with a screen protector on it.
Cheers
Hi,
Last week I used to be outside with much rainy condition.
Though it never got totally under water, many times it's screen got wet with substantial rain drops.
Slowly, phone started misbehaving with following symptoms,
1. Around 10% of left side of touch screen doesn't show response. I enabled show touches from developer option and when I try to touch left side, say "a" letter in keyboard, it doesn't show touches and pointer jumps immediately to left edge.
2. Many times, I am not able to unlock phone as no touch are detected.
3. After unlock, many times though I am not touching phone, it shows couple of pointers (I enabled show touches in developer option to trace this) on left edge. It keeps moving resulting in erratic behavior, say screen zooms in and out, some icons clicked automatic, deleted automatic etc.
4. Sometimes I noticed that capacitive buttons are also not responding.
For all above, I have to off (not complete switch off)and on the phone. After few attempts, it becomes responding except point 1 above.
I have reflashed ROM (Vivikat) just to ensure it's not software issue.
Now it seems hardware issue with following two possibilities...
1. It's matter of some moisture in phone only. I have to try hard to dry out all moisture and phone will become responding.
2. Digitizer has some issue and may call for replacement (I don't want to do that...:crying.
Can you guys share your views/experience and advise?

I just had touch screen issues but not with water or rain. It was the CPU. Almost whenever I overclocked it, I had touch screen issues. Both misbehaving and not behaving at all. Change the CPU frequency and restart the phone and see what happens. :good:

Thanks for your reply.
I have never overclocked my device.
However, I tried to underclocked it if by any chance, it can solve the issue.
But issue still there.
A small portion of left column on touch screen seems not responding or giving erratic behavior.
Does, water can damage digitizer to that extent that can not be recovered even after drying
Or, I should keep hope and wait more before I go for digitizer replacement

If the digitizer is damaged, it is probably done. But if you can open the open, check the digitizer and see if there are any things stuck on it. My recommendation: ask an engineer to open it and clean it with the special spray they use to clean electronic parts. Maybe the water has had only a side effect and it will be fixed by cleaning the digitizer.

You're Welcome buddy! :highfive:
Anyone else having problems with the sensitivity on fast scrolling? Seems to not be as smooth or compared to the iPhone 6 and HTC One M8 I have been playing with...It's almost too sensitive or something, I can't quite put my finger on it.
Do you mean the effect where things sometimes bounce back while scrolling?

There is an earlier topic about it here: http://forum.xda-developers.com/z3-compact/help/swipe-issues-t2888154
The phone has an extra-sensitive touch screen because it has a "glove mode", and I'm thinking the effect of the technology for that glove mode isn't completely suppressed when the glove mode is disabled, so the touch screen would still be slightly more sensitive than those of other phones, even when glove mode is disabled.
If glove mode is enabled, the touch screen is so incredibly sensitive that without gloves, it will register a touch when you hover your finger about a millimetre above the touch screen.
I found that for me it helps to use "lighter" and shorter swipes. Also after a swipe lifting my finger a bit higher off the screen than I was used to.
Some people might always have been doing shorter and lighter swipes, hence not everyone is experiencing the problem. It's also been said on the Xperia support forum that not all units use the same glass for the front; some use "gorilla glass", others use "dragontrail" glass. That could also be influencing the touch screen sensitivity/behaviour.
I've adjusted my swiping habits relatively quickly and now I get the bounce back effect only once in a while.
I do hope that Sony comes with a firmware fix to compensate for the over-sensitivity though.

hi, is it normal? happen to my unit also.. quite annoying i can tell.. different with my TX..
Go into developer options and enable "Show touches", perhaps touch the screen a few times then turn off show touches.
Sorts it out for me! I was having a nightmare swiping down to select words in Fleksy.
This workaround will do for me until Sony fix it properly!

I really wish there was a way to turn down the sensitivity. During typing, I frequently have screen presses register as very short swipes, which is incredibly irritating, as I then have to backspace and delete two words.
Not really helping you, but this shows how sensitive the z3c display is:

Touch screens usually respond to metal. The screen of my Z2 tablet does.
My screen is so sensitive I can operate it using my leg... through the pocket. I saw in Z1 and Z2 threads that there is a config file that can be adjusted, however I'd have to root in order to do that, and I don't want to risk losing my warranty (esp. not when reading about glass breaking by itself).
It's not a massive problem -- all it takes is switching off "double tap to wake" and camera launch button. But those are features that are useful. On the other hand, having my phone suddenly switch Torch on, call a random person in my phonebook or reorder icons on the launcher desktop isn't all that exciting either -- not a fan of surprises.
Has anyone else found the Z3 Compact screen too sensitive? (Glove mode is off, obviously.)

On my previous phone (xperia acro s) it often happened that my leg messed with the phone when the screen went on for the alarm going off in my pocket. It was really annoying. I was always afraid that some important settings changed without knowing it.
My screen is so sensitive that I the last couple of weeks only have managed to send a few sms without having to delete several words that are written wrong...!
The speeddialer is also terrible and often leads to wrong contacts...
This phone is by far the worst phone I have ever had regarding these issues!
Is this a sign of a faulty phone or can you relate to these problems as well?
Is there a solution???
My speed dial wasn't working out of the box. Had to make a factory reset, that fixed it. Sensitivity isn't interfering with my writing though. My previous phone was a bit bigger so I had to get used to writing on a smaller keyboard. But why would touchscreen sensitivity be an issue when writing anyway? Are you using a swipe keyboard?
No I'm just using it out of the box settings...? I can see swipe is enabeled but I text normal... I have had to disable autocorrecting words when I write... It is really strange... I have had many different smartphones over the last 15 years and this is by far the most responsive ever tending to be useless because of the many mistakes I make during calls and sms...
I never had any issues what so ever with my M7...?
I have just disabled "motioninput" (roughly translated from danish...) under Xperia-texting and this seems to have helped alot!!!
I'm on the same boat - it's too sensitive compared to my m8. Hoping for update to fix it
You really should try to do what I did and disable motioninput! It really helps ??
I'm on the same boat - it's too sensitive compared to my nexus 4. Hoping for update to fix it
I go into running apps and force stop com.sonymobile.touchscreen.touchfilter.tfpss and it seems to be a little better, still sensitive but at least no bouceback. I should try pm blocking it.

I've tried this as well, but unfortunately no change, I still get bounce-backs when I don't use particularly light and short swipes.
