[Q] Touchscreen Problem

i am finding it difficult to chat with someone because when i type 4 or 5 words some keys are automatically pressed. in my case they are "s" and "d".
this is also sometimes experienced in menu options and random opening of applications from homescreen.
please help me...
and this is hardware issue or software?
any help would be greatful.
EDIT : the same issue was experienced in lg optimus one (p500) and was fixed by a bug fix

please reply..

it happens sometimes but only when im using at launcher other than the stock....never happens with the stock....but its very rare nd it goes when i lock the screen...

never happened wid me.. may be its software problem.. as if it had been a hardware, then u wud be facing problems in other application and games too..

Me too facing same problem.

I've other problems concerned the touchscreen or touch-wiz or else.
- Sometimes a call rings, when I slide the finger on the touchscreen to answer the call what happens is that the call stays on but the phone keep vibrating and I can't do nothing but turn the phone off. The call can't be heard.
- Also sometimes when I hang a call because the other side not answer I touch the screen but nothing happens. The call stays on. Solution: Power off the phone.
- Other times when in a call after 40 seconds the call stays on but the sound off.
I did a factory reset and at this moment I don't have any extra app instaled, to see if these problems persists,
What I need to know is if someone had this problems with this model.

I updated my friend's SGA to Villain ROM and she is facing the same issue.. Its a touch calibration problem.. Unable to use the keyboard, it keeps typing something else. I am upgrading to the Code ROM.

this issued is being faced in every 2.3 rom by me

Trying ur original stock fw if problem still persists then something wrong with ur touchscreen hardware and its calibration.
As other users r not facing this problem this is not bug.

stock rom is working fine without any problem but as I flashes european firmware this problem starts...

One of the likely causes is the CPU hitting maximum, and thus the touchscreen doesn't respond I am getting this sort of thing a lot more often.

Im also having the same problem in every rom i try.... n it really annoying when i must retype the message again n again... can someone help me? how to recalibrate the touchscreen? thanks before

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.
Sent from my C6603 using xda premium

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.

touch problems, starts zooming instead of scrolling

It doesn't matter if I have stockrom or custom (as we speak iHackers stockrom 1.1) the touch drives me crazy.. For an example when I surf on the Web and want to scroll down it works time to time then suddenly when I press my finger on screen it locks on that spot and start zooming page instead.
Exact same problem with the Facebook app.. Some setting? Would really like to disable it. If it's possible.

There's already a thread dedicated to the touch issues if you search a bit. In my opinion it's a hardware issue. I think it has something to do with a short somewhere between the case and screen.
Look here: http://forum.xda-developers.com/showthread.php?p=47791462

There is no need for forum members to start a new thread about the same issue every day. You could have posted your question in any of these 4 threads that discuss the exact same issue.

And to answer your question, it isn't a setting and it isn't related to any specific apps. It's a widspread issue that affects a lot of Z1's and while there are many suspicions, there isn't any confirmation whether it's a hardware or software problem. A Sony rep called Rickard has posted about a fix that is coming in the next software update here but it remains to be seen if that fix actually works.
Right now the best advice we can give you is to take your Z1 to the place you purchased it from and ask them to get it repaired or replace it with a new one under warranty.

Welocome aboard with the Touch Screen Issues. (just kidding, I know its not happy time)
BTW, return your phone to the Store where you bought it to repair or replace via warranty. It's 100% faulty device.

Dude have you seen the latest leak of Sirius in XB? Maybe what the sony rep is saying a fix will come is that they will port the glove mode to the z1

I didn't. Do you have the link? I think they are aware now of this problem and they try to fix it, I hope so, but for the solution we still waiting.

Mine did the same thing, I tried rebooting it and the problem went away for a day or so, so now I use an auto reboot to reboot every morning at 3am. Done this for three weeks now and the problem has vanished.

I totally agree, Sony dropped the failbomb on this. I just hope my method solves the problem for other people too.

on 4.2 it never happened to me.

Maybe on 4.2 you didn't know how to reproduce it but if you want to know my touch screen get worse after upgrade to .290 so you are not the only one.

correct, also when long pressing you can see that the screen fails to recognize the touch after a few seconds. really annoying when playing games.
BTW @eclyptos did you got your phone back?

Hello. I have been looking this forum from long time and thx to the developers and everyone who brings to us all the stuff.
Soo about my problem. Its similar to the first post, but with one exception.
My phone display cracked and so i give it to be repaired. Everything was working more than perfect then, but after the change /ofc display works fine/ but keeps shutting down when i try to use applications/games or even when i open the camera/. When i try to turn it on it goes to the sony logo and then nothing... /bootloop/ turns off again. I have to plug the charger and then phone comes back to life when i turn it on. It heats abit more /i think/ than before. Ofc before was heating too but i didn't face problems like that. Soo my question is... can be a software problem or hardware problem? Im using the last stock rom as it was given from sony.
Any help appreciated. Thanks in advance...
Best regards.

U-touch problem

Hi all,
New to this forum. I used my phone during light rain, and thereafter realised that the U-touch button became totally unresponsive to touch (physically pressing it is ok), including swiping, long press, short press and fingerprint sensor.
Anyone facing the same problem or can suggest how I can rectify this? The only thing I've tried is rebooting but it didn't work.
Thanks!

Hi,
I never had any problems with mine.
Did you go into the settings and reset to defaults?

But they say: U-Touch 2.0
Innovative Wet Hand Mode
So they want you to touch it with wet fingers

It sounds like the perfect time to flash CM on it.

Bumping because I'm curious if the OP solved this issue and if others have encountered it. Should I be super careful not to use the phone in any kind of rain?

Any update on that problem? I have the same problem. I'm already considering buying a new home button...
