Thats the famous Touch screen bug of SP. While charging or after charging SP's screen will not respond... Some users face this problem before... I think u have to giv ur mobile to the service center for a replacement if u have Warranty

I have this problem too... And my XSP is out of warranty perhaps that could help us? http://forum.xda-developers.com/showpost.php?p=35934117&postcount=1 But the phone won't let me to install that apk
I'm a bit desperate so I have also tried to use this apk: http://forum.xda-developers.com/showpost.php?p=10995856&postcount=1 and even an apk for Xperia Z Ultra: http://forum.xda-developers.com/showpost.php?p=46177477&postcount=1, still no luck Can anybody help, please? Is there a solution for this bug?

if u are rooted go to system/usr/idc/clearpad.idc
touch.pressure.scale 1.0 [instead of 0.0074]
touch.size.scale= 20.00 [ instead of 16.91]
touch.size.bias= 70.00 [instead of 67.65]
i take it from somewhere i dint remember...
note: im on recaf 4.4 but those unrespond touchscreen while charging also there... i think its a hardware problems T___T

I have the same problem. It's strange because when i'm using my samsung charger there is no problem, but with the original one the touch is often unresponsible.
I think that the problem comes from the charger.

When your phone is on charger and your touchscreen is not working properly remove the charger, clean it and wrap a copper wire around it. The thinner the better. The problem is caused by bad earthing from the electrisity and this causes the touchscreen problems

Can it be the problem come from wrong root?
To become a good respond from touch i must hold a finger on the frame, hold it on hand, plugin USB or put on metallic ground. (phone rooted)
After unroot/repair with SUS the problem was gone. I can charge, reboot, lock, unlock or any other thing, but i have extremely good response from touch on all undergrounds.
After root the problem is coming back again. doomloard or chinese root its the same.
Here is a Video after root: http://www.youtube.com/watch?v=6JZJj867DQI
I think we need a better root.

Yes and no.
Yes: Only if you modified systemfiles regarding touch
No: Since it is a hw issue. However after a reflash i did not encounter this issue at my phone. I also have Glove mode disabled :good:

THX,
that can it be. After any test, now i can say problem come after flash a 5 button navbar.
Now i use Xposed module "GravityBox" to mod the navbar and my touch works perfect on rooted SP :good:
Now i will see it come back after any time.

Hi all.
I'm a complete novice at this but I bought this phone today and have the top of screen not working problem, rooted through towelroot(?) and now I'm trying this method but after I've entered the values it keeps giving me an error message. Is there a step I'm missing out to get it to save? I'm using ES file explorer if that helps.
Cheers

genius.
worked perfectly. i can even type now in a fal surface:victory:

Touch Screen permanent fix
Had intermittent touch screen issues for over 3 months
Tried different stock kernels and stock ROMS 254/205 even tried the clearpad.idc tweak ..........and yet after a few days the issue returns
Restarting the mobile solves the issue for a short period of time
Leaving the mobile on a any flat surface can make the issue return
Clutching at straws I rooted and unlocked the bootloaded and installed the MIUI Rom
....the touch screen was terrible right from the first boot ......then I had an idea of trying different cases on the mobile!!!
All was solved just by changing my case over to a soft rubberised silicone one
The screen just started working as if by magic, I took the rubber case off and the touch screen stopped working right away...!
Anybody suffering the dreaded touch screen Xperia SP on any ROM simply fit a soft silicone/rubber case
It seems to restore the touch screen back to 100% all the time on any surface

It worked for me since day 1 (last year), original thread is HERE by mrsatan though.
Was included it in my rom for X10 on the past and it worked flawlessly, but it may reduce battery life a little bit.

Help: My HD has suddenly gone dead

My hd has suddenly gone dead. The battery light does not turn on even if plugged in. I have tried to reset while plugged in but nothing happens. Connecting to the pc also doesn't help. Also tried to put it into bootloader without success. This does not feel good. Any ideas what might be the problem?
might be the usb connection. could be loose or bad
Have you tried to remove the battery, and put it back in..had a littel problem like (during unlock) that would turn on, removed the battery for 10s and put it back in and it turn on.

HI Bro Iknow ur pain, this happen to my diamond also, one day just didnt turn on after unplug from my vista machine. Only thing I could think of is that maybe there was a short circuit somewhere between pluging to the computer with usb.
You will have to send it for repairs unfortunately

I tried this and it magically came back. The strange thing is that I had been taking the battery out and putting it back in many times ...but perhaps I had not left the battery out long enough.
The battery also seems full which is kind of strange since I had been using the phone all day without charging.
In any case, I will leave it charging over night and report back tomorrow.
Thanks for your help!

You'd better reflash a stock ROM and keep it for a while until you are reasonably sure that it was just a case and won't happen again.

I am also trying to use the same soft, but no luck... could you please, eventually by PM, tell me the steps that worked for you?
And it can be in Portuguese... ; )

Dead again
Well...it did happen again. This morning I found it dead again while plugged in. Unfortunately, I did not reflash it to stock rom. I can now only hope that I get a second chance to reflash before sending it off. Any other ideas are welcome.......
entering the new year without my blackstone
Looks like my hd has to take a trip to the factory.
Quick question: since I didn't manage to revert to initial rom does anyone know what the policy is on repairing an htc with custom rom?
That is indeed unfortunate...
What custom ROM have you installed? Have you checked in the thread if someone else had similar issues? And have you installed any particular program?
Also, you had no such issues while you were on the original ROM?
If you have this type of issues, trying to flash a stock ROM without being sure about the cause for the issues might be a little dangerous... There would be, I suppose, the risk that something might go wrong during the flashing process. And you would risk having a lovely brick...
Regards,
P.
I have installed Panosha's light version. No one else seems to be having this problem. Is there a chance that the battery is faulty? Can I have it repaired even though it has a custom rom installed?
Hi,
It might be a problem with the battery, but you could only try this possibility if you used other HD... by the way you have been using the wall charger or the usb cable attached to the PC?
Regarding the possiblity of having it repaired, under warranty, it could depend on the repairer itself. At the limit they could refuse to repair it under warranty, because a non-official ROM has been installed, and, specially, because a non-original HSPL is in place... but they could also overlook this, or do not notice it.
I would make sure it can not be "ressurected" and properly flashed before going to HTC service.

I have tried several times to resurrect it without success. On one ocassion I had the power light turn on for about 2 seconds then dead again. The only thing I have not tried is to try another battery. I will probably find one by tomorrow to test. Otherwise on Friday it will head to the repair shop...and fingers crossed. I will let you know what the repair policy seems to be here in Greece.

Your phone is not broken!
Duttys ROM does not have this problem. I have had the same with Panosha's ROM and with Touch of HD ROM. The screen goes black and only removing the battery brings it back.

I wish this were the case, but even after removing the battery I cannot get it to function. Even when plugged into an outlet the power light does not turn on, so it's clearly more than a blank screen.

[Q] Milestone touch screen problem???

Then I noticed there's a vertical line, that goes from the Setting button to the top of the phone that doesn't work. It simply stopped working... Some1 Help me pliz.

Are u using a custom Rom or the Original ? My touchscreen had a similar issue, and reflashing the ROM solved it. It took 2 flashes, but the issue is gone.
Dont know if yours is the same, but if the issue still remains, atleast it can confirmed that its a hardware issue and not a software one.

I have used CM6 on my phone, but when i got this issue, i made my phone back to 2.1. The problem is still standing.
uh oh. Looks like a Hardware issue then. U still might wanna take to the store and get it verified. Is it still under warranty ? Any possibility of an exchange ?

Havent seen any such issues.. Thanks god..
it's similar to my problem, I had the back button through the top of the screen not working..
I have tried flashing, factory resets, and whatever I can do, but still no changed,, so I tried to ask the closest customer service and they said that it's the touchscreen panel must be thrown away to get the new one..
is it really true ?
please share this problem,,

Hi all!
I was having the same problem with the column of numbers 3, 6, 9 of dialpad. Looking for the solution in google, I have read that this problem is probably caused due to the moisture... so yesterday I turned of my milestone, removed the battery, SIM and SD cards and left it inside an enviromental chamber @ +70 celsius degress for 1 hour and guess what? Problem solved!
I hope that it works for anyone that are having the same problem!

I have had good success with a combo of rice (inside a ziplock bag) to absorb humidity and/or a toaster over at the lowest bake setting.
Worked on MANY electronic devices over the years.
Sent from my Milestone using XDA Premium App
Same problem here. I've solved it by changing the digitizer (ebay 25 euros). Works fine now but in the mean time I change for a Desire HD... good by Milestone !
If you decide to change the digitizer, be patient, fixing th Milestone is not an user friendly task But if you take your time it's ok !
ive the same problem, and i believe that's because of moisture. because every time when its raining except the problem with right side of screen im not even able to use the phone touch screen doesn't work at all and the phone just does something by itself! this issue started with small vertical bar from right side of screen and it growing everyday now im not able to use right side of screen till home button.
i want to know do i have to replace touchscreen or i can fix it with something to absorb humidity?
thanks in advance

Xperia Z Touchscreen troubles

Hi,
Lately i am experiencing a lot of troubles while typing a message or just unlocking my lockscreen.
The touchscreen respods bad, sometimes it starts moving out of itsselve... Its really annoying to work with the phone like that...
Someone facing the same problems?
Suggestions? Fixes?
Btw. The phone is stock, nothing changed or replaced...
The onling thing i did was removing the shaterproof film (and my Sony logo )
Try repairing it with Sony's PC Companion or Sony's Update Service first.
remember to backup your stuff before proceeding.
Do full wipes.

Did you try to shut the phone down for 30 seconds and restarting it, seems to fix many unusual android issues.
I have noticed sometimes that my phone on the odd occasion does not repsond to screen press.
I am also experiencing the same problem.
Did a factory reset but still the same problem comes occasionally.. any solution ?

I've had this problem only sometimes when charging outside...When u feel that the touch isn't working as it should,put on your earphones and look out for a low buzzing sound..if u hear anything,then unplug the charger from the wall and check in another socket..hopefully the problem in my phone was that current was leaching onto the capacitive screen so if I touch just once,it registers a number of touches..hope this helps u get rid of the problem

That may be the solution to the problem you had but this isnt the problem here , it happens when whether the phone is charging or not and I think themichelanne is having the same problem.
Power off the phone with power+ vol up - wait for 1 vibrate followed by 3 vibrates and leave the phone then wait for 30 second before powering on, solved it for me....no problem in touch till now and i hope it does not come in future.
BTW This phone is really really full of problems.
Also happens to me when using some chargers
I bought my unbranded UK Xperia Z in Expansys, since I live in Portugal they sent a extra charger for the european standard socket. I had this exact same problem with it, the screen was extremely unresponsive and unprecise while charging. Now I use the charger from my old N900 and have no issues. Also, charging from a lower volt/amperage source like a computer I have no problems.
Since the capacitive screen is very sensitive, a low quality AC-DC adapter will generate issues (possibly due to the current/voltage not being 100% stable).

The issue is still unresolved, i did a factory reset but still the touchscreen stops responding ocassionally...
Need serious help guys...
Could be a bad screen protector.

me too
Im also experiencing the same problem. So annoying, especially while texting. Xperia Z's touch not proving to be how it should be.
This happens with this phone for me, and previous android phones. Usually its just the app open not responding to touch events, but my softkeys still work and I can force kill and restart whatever im doing. Sometimes I have to reset. It seems to be happening more frequently since updating to 67, but its not often enough really bother me. using a tool like romtoolbox to increase the amount of touch events android can process seems to improve it somewhat.

Have you found any solutions for this? I have been experiencing this since 4.2.2 update. I don't know what happened. Can you please explain what's wrong and what's happening? Have you got it fixed yet? My screen freezes frequently so I'm unable to use the phone.
I have been experiencing this problem since a long time. But I have found no solutions for it. I took out my screen protector and the freezing thing got to normal but still it freezes sometime, but more when the screen protector is on. I'm pretty sure this problem is caused by the screen or the android farmware. I'm downgrading my OS, please reply to this. Mine is C6602. C6603 doesn't experience any problems like that.
How I fixed my Xperia Z5 touch screen
Hi everyone,
So, my Z5 touch screen was not working at all anymore, I have tried every manipulation recommended on the internet but did not succeed to get it working that way.
Here is what I did to get it fixed eventually:
- Installed sony companion
- Launched the "fix software" program (I don't know the exact name of the program in english)
- Followed the steps (took a while, something like two hours)
Then my phone rebooted, but nothing, still the same issue. Tried taking off the sim card, rebooted and same problem. Then, I put it back in the phone, and for some reason, the touch screen decided to work again. Although, I lost a lot of data in the process, but worth it.
I don't know if it is a general fix, but on my phone it just worked that way. Although, I have noticed that my phone started overheating something like two weeks before the touch screen problem appeared, I assume those two problems are linked in some way. Still did not find any fix for the overheating problem except putting it under cool water or let it cool down for 10 minutes.
I hope I helped with my post, good luck for those who are experiencing this issue.

[POOL] About the touchscreen problem

I only discovered the touchscreen issue yesterday doing the test of the other thread. So, i would like to every z1 owner to answer this pool to know how bad things are and if we can try to find a solution, since i think Sony won't.
So, please answer the poll and post any useful information. I'll start.
My phone model is C6943, I currently don't use case and I'm using a screen protection. I can do the xperia touchscreen test without touching the phone body without problem and also doesn't have problem with pattern password.

Pool? I think you mean "poll"
My 6902 is completely screwed. At first I used a screen protector and the problem wasn't too bad. Then I removed it when I took the phone in to get another issue fixed and soon after that the problem got very bad. I was traveling so couldn't go back to the service center. Now it's a bit better, randomly works and randomly doesn't. When I was home in cold weather though it seemed a lot worse than it is now that I'm back in India where it's warm. Not sure if temperature is a factor, or could be conscience. But a few weeks ago it was so bad you couldn't type even a two letter word using Swype.
Also, I now have a part of my screen in the form of a horizontal line where touch doesn't work at all. No single touch and no drag. Completely dead. Taking it to the service center soon.
You should vote on the first option, then
Guys, check my post "News from whats is causing touch screen problem" to see if is your case!

It's not.
I got problem unlocking with patterns, scrolling pages and when I play some games after few minutes it stop working so I voted the first option. My phone is back to Sony, I hope they know what to do and at last it's Made in China.
Please, post if you use case and screen protections too. This could help understanding the problem.
Additional data : Z1 is being handled in a leather case, back and screen protector removed ( not the one with the logo, the plastic ones that makes your camera blurry )
Touchscreen problem seen in the game Alien Shooter, after some playing, the touch screen becomes less and less responsive ( i tap a button to shoot and use some onscreen joystick to move ) - both become unresponsive/less responsive as you play and the phone gathers some heat ( you can feel the touchscreen becoming hotter )
i have a simple tpu case, i had a bit of problem when playing all touch-based games (not ones with gyro like asphalt).
ever since i got the case it's better, i have the ASF and nillkin matte screen protector

I did not use any case just a chip screen protector. Anyway on a good healthy touch screen the screen protector should not influence the touch screen respond.
Hey guys, I have also this touchscreen issue, and I would appreciate if you give a feedback about warranty service, if sony accepted the problem and replaced a touchpanel or not, and also if the replaced touchscreen is better or not. I´m also thinking about sending it back for warranty repair.
I have also found that my phones touch screen is temperature sensitive, when it get cold or warm it just refuses to detect touch actions. Try it yourself put the phone into cold/hot water for 5 second, take it out, quickly clean the display from water and test the touchscreen. I first tought this behavior is normal and I didn´t cared until I started to play games. After 15minutes of playing the touchscreen bug every time appears. But also after a while its randomly disappears. So this thing is strange. (the bug appears identically also when I have my phone in a plastic case)

Same here. I sent my phone back last week to the store where I bought it 2 months ago. They will send the phone to Sony Center but the time for repair or replace the device will not be 2 or 3 days but from 2 weeks to no eta. When the phone will come back to the store they will send the phone to me. I will post if the problem persist or not.
The problem is if they return a phone with the same problem.

They should be aware about this issue even on the new device so at this time they probably will check that but if they return a phone with the same problem, I will send it back again like many did. Someone had to replace the phone 3 times and I will do the same.
IYeah, you will be a long time without your phone though. I think I'll wait a bit since i rarely get the error and actually only when i try to reproduce it. How bad was yours?

I was able to reproduce the problem in many ways, Touch Screen Test, Opening the phone with Patterns, Scrolling Pages or with Launcher instead of switch the page it was opening the applications and at last when I was gaming at one point the touch stopped working and I had to wait, so this made my mind to send it back. On daily use was all ok but in some circumstances was frustrating.
i had the problem with cm11. and when I retored to stock then the problem was gone:S
I'm on stock and I got the problem.
Today for the first time I got the problem when writing on handrite. So I thought about using my phone warranty to get anotehr one. But it don't always fails when i do the method to reproduce it. So, how do you test if your new phone is working and how do you prove that it isn't? I mean what if i take the phone to warranty and it works?
And for you who already changed phone, it is working?

Help with touch related problem

Hi guys,
My Xperia ZR started behaving abnormally some days back, I put "screentouchtest" app and found that there were random inputs on the phone which made the phone go useless... Check the screen shot attached.
So I tried to make an app that will disable only that part on my screen and I was successful at it... Check screenshot attached. I could then at least use my phone to some extent.
But now the frequency of these random touch inputs have increased and that has made it again go unusable...
Problem is that I made this app as a floating app and whenever user touches other part of the phone , touch below the unblocked area is activated.
SO now I wanted to disable the touch completely over this area...any help will be appreciated.
Sony says it is due to water logging in the motherboard and no warranty will be given.
You are not alone!
Having the same problem here. Random touch inputs on the top right corner of device. I can assure you it's not because of water log of any sorts because i have opened ,checked, dried and even tested the touch display. Its a software related issue I guess which I am not able to pinpoint or understand. I wish someone from the forum helps with it.
water logging? did your phone get wet some time? its waterproof phone and no warranty given? :laugh: screw sony in consumer court

If you think its a software problem, i'll try putting some custom ROM.

Yeah I know Its waterproof. My brother was using it so not sure if there was water logging. But when we went to customer service the condition of the mobile was not good(Plastic that covers charging port was loose) so couldnt fight actually.
Custom rom doesn't help

Sorry to say unfortunately custom ROM doesn't help either. After I installed one just to see if the problem persists, To my surprise it didn't! But after a week or so the pendulum was back to square one. So I had to roll back. I really don't know how to go about this problem I think the problem is because of a bug of some sorts which causes the chip to send signals to the display addressing that its being touched or whatever. Anyway this is just my guess. You can try installing a custom ROM for your device and see if the issue ceases. In that case my problem would be just device specific. Do share your results after you install a custom ROM :good:.

May be there is a problem with the touch digitizer under the LCD panel which is misbehaving. No software can fix it. You will need to replace the touch digitizer along with LCD screen as they are sold as single unit. Check online if you can find the parts and ask any local mobile repairer to replace it. :good:
NO Luck with Custom ROM
I put Android Lollipop (CM12 Port) and there have been no change. Looks like the problem is with digitizer, last time I told local repair shop to replace the screen they said they cant separate the screen and had no clue. But I searched and found out from youtube videos that it can be done. Now all I have to do is buy Screen+Digitizer.
As you can see the random touch strip have moved little upwards from my earlier screenshots. That happened months back. If anyone wants the app I made then let me know. It helps me to some extent.

Which app did you make? What does it do?

Where can I buy 1? Online? Link Please...
Since there are random touches on my phone, I made app that blocks this touch... Check the screenshots, I have "Show Touches" Option ON from Developer Settings. This makes all the touches show white marker... So I made app that floats over the screen and wont show any response when there are touches over that area. "Semi Transparent Area" in the screenshot - Touch wont work over that part. App wont completely disable the touch though, if we press other part of screen for that time app gets disabled...

Finally, a solution. Time for a digitizer+screen. Thank you guys.
Hey what is the app you made? I'm in the same boat but can't really afford a new digitizer....
Yep i need it too. It will be greatly appreciated if you share your app here. Thanks in advance.

sorry guys for late reply!
I am attaching the apk here...
I have this problem too but it only happens if the phone screen get wet
Some time it happen randomly but when i press on the screen at bottom and on led gently it disappear and back to normal
Thank you!
The Float APK solved the major issue of my faulty touch screen in my Nexus 4. There are two lines in my screen where the touch is not working anymore. One of them is having several crazy clicks making my phone somehow useless. By using this app, I can prevent that, which is great!
Two issues I've got:
- the textbox to set the distance from the top is located exactly in the first dead line! So I need to turn my phone sideways to be edit to click there and edit its value.
- when using the phone in horizontal mode, blocked zone turns as well, but the faulty zone is fixed there.
I'm wondering if you might share with us the source code or maybe you consider to make some improvements on it?
Thank you so much for sharing this app here!
thanks for this app solution.
I too have problem of ghost touches. This app definately helps with that and makes the phone somewhat usable again.
The only problem is that some ghost touches are continous (it's like someone presses their finger on the screen and keeps holding it there). This makes action by other touches unresponsive.
Maybe we can find a solution for this in the float app?
Source code for the app
Finally since many of you requested, here is the source code! - Stop Touch - Source Code
