[Xperia Z1 Q&A, Help & Troubleshooting] :
Yes most people have it this way but I still believe it's the same problem. Some just have it worse than others. I had the issue constantly while holding or using the device and not when setting it on a flat surface... But then again right now I'm waiting for my replacement.
[Xperia Z1 Q&A, Help & Troubleshooting] brapicoco:
No dude, my phone is naked. I just have an additional screen guard also at the back of the phone. I tried also putting a case but I still have the issue. My issue is a lot worse when it's in a case.
[Xperia Z1 Q&A, Help & Troubleshooting] shteren:
Metallic or plastic case? Metallic should make it worse.
[Xperia Z1 Q&A, Help & Troubleshooting] brapicoco:
Never had a metal one. But tried plastic and leather and both have the same issue. I think it's better to have it naked. Mine works okay when touching the frame but still produce the annoying issue
[Xperia Z1 Q&A, Help & Troubleshooting] @ARC-S@:
Guys here maybe another cause of this tocuhscreen problem :

In Sony's webpage about the Xperia Z1's design, it says "One example of this is the aluminum unibody frame. Full-metal frames have caused some problems in the past with signal reception, because they interfere with antennas inside. We took a fresh approach by developing a metal frame that doubles as the antenna."

Site : http://www.sony.net/SonyInfo/design/works/products/xperia_z1/01.html

This may somehow interrupt the touchscreen digitizer and make the screen go crazy.

What do you guys think?
[Xperia Z1 Q&A, Help & Troubleshooting] brapicoco:
I can't really comment on this one since I'm not an engineer. However, I think that our screen is shorting out or has some bad grounding.
[Xperia Z1 Q&A, Help & Troubleshooting] eclyptos:
New FW .136

Guys, the new FW improved with White Balance and Bug fix was uploaded today, HERE Post #36, I don't have the Z1 at the moment so I can't test it but probably you can so if somebody will try to flash it please confirm here if the problem with the Touch Screen persist or not! I appreciate your help.
[Xperia Z1 Q&A, Help & Troubleshooting] jsauce75:
So I called tmobile today to report this issue. Not only was the tech support lady aware of the issue, she said that it also existed on the z and was never fixed. She then went on to say she specifically asked the Sony rep if these issues would be ironed out by the release of the z1s. He assured that they would. This obviously was not a true statement. She advised me to go to the store and pick out a different model because even though Sony has been aware of this issue for years on multiple models they have not resolved the issue so there absolutely no reason to think they will fix it any time soon. It's hard not to take her advice.
[Xperia Z1 Q&A, Help & Troubleshooting] eclyptos:
Yep, this situation is exactly what we try to avoid and we know that Sony do not want to acknowledge this problem but we try to don't give up and maybe even if they do not say anything the fix come soon or some improvements with the new FW. I don't know how many other device I will buy from them but on paper the specification of they product are awesome but they screw all of us and this make me sad.
[Xperia Z1 Q&A, Help & Troubleshooting] brapicoco:
Yo [MENTION=1030880]eclyptos[/MENTION] someone who has the touch problem reported that he cannot reproduce the issue anymore with the new FW. I asked him to further observe the problem so I think there is a slight hope for us.
[Xperia Z1 Q&A, Help & Troubleshooting] chunlianghere:
i jus flashed 14.2.A.1.136 n did the test on the touchscreen problem.

i would say alot of improvement n alot better.

but the problem do exist on my 1st n 2nd test after a very long long "line" drawn, but disappeared awhile.

did 3rd (with charging) n 4th test, however the problem was gone. i keep drawing the line until it was a total mess of "lines".

*update: problem was back when i play dead trigger 2.
[Xperia Z1 Q&A, Help & Troubleshooting] brapicoco:
so no fix for the touch problem. mine happens randomly sometimes it's okay for an hour or 30 minutes. Shortest is 5 min. so if this happens on the new FW better not upgrade :(
[Xperia Z1 Q&A, Help & Troubleshooting] jsauce75:
I was messing with the settings tonight and I may be on to something. I turned the pointer speed setting under language and inputs all the way up and I haven't had an issue in the last six hours. I have been trying hard to recreate the issue and I haven't been able to do it! I read some posts that told me to turn it down all the way so I figured I'd try turning it up all the way for ****s and giggles. So far so good, but far to early to call it a fix. Hopefully others can test it as well. I'll report back later with an update.
[Xperia Z1 Q&A, Help & Troubleshooting] shteren:
Just tried it... Settimg it all the way up did nothing but

Setting the pointer speed all the way down actually helped! I'll try some dead trigger and see if it happens.
[Xperia Z1 Q&A, Help & Troubleshooting] brapicoco:
mine did not helped at all. issue is always there and the frequency is not reduced
[Xperia Z1 Q&A, Help & Troubleshooting] eclyptos:
Because the Pointer Speed have nothing to do with it, it's just the speed of the arrow when you connect a Mouse via bluetooth and the people who saying this help they not to have a clue of what they saying.

Sorry to hear the problem still here, my last chance is KitKat somehow, if I will not get improvements there then F...off Z1 and Sony.

Still a chance the phone come fixed from Sony Service via warranty, I will post when I get it.
[Xperia Z1 Q&A, Help & Troubleshooting] brapicoco:
i think sony does not care anymore about our z1. im gonna change brand if kitkat does not solve this
[Xperia Z1 Q&A, Help & Troubleshooting] eclyptos:
I don't know. Relatively.

Let's not give up. ;) This should going somewhere.
[Xperia Z1 Q&A, Help & Troubleshooting] shteren:
yeah, i was able to reprocude it again after i wrote that, anyhow.

with my tpu case it's really hard to reproduce it since i need to push it aside to touch the metal fame, i played dead trigger for 30 minutes and touch was perfectly fine.
[Xperia Z1 Q&A, Help & Troubleshooting] brapicoco:
I flashed the .136 last night and preserved my data and guess what? the touch issue seems to be completely gone. I'm really having a hard time reproducing the problem during games and especially on bed and flat surface. It seems that sony tweaked something.

The problem is there but you can't see a continuous broken line, the line resumes after a short break. Will observe further and post on this one ASAP cheers!
[Xperia Z1 Q&A, Help & Troubleshooting] eclyptos:
You see, finally good news, I wait for mine now. ;)

I guess with the next FW or Kitkat we can forget about this Touch Screen issue. :D (I hope so)

Keep let me know if anything change, Thanx.
[Xperia Z1 Q&A, Help & Troubleshooting] brapicoco:
Sure dude, up to now I'm having difficulties in reproducing the problem. I hope that they can retain this fix in kitkat
[Xperia Z1 Q&A, Help & Troubleshooting] Geoffxx:
you know what guys, I have 2x Z1 phones and they both run as far as I can see perfectly well, sometimes when I open the lockscreen I have to put the pattern in twice which takes all of about 1 sec, could this be a quirk of the touch ? well I don't know and I'm not interested because generally I am very happy with the overall features build and performance, I've never considered even looking at another device

I'm subscribed to this thread and get the updates as posts arrive - I've never even tried to replicate the issue described here on either device because they do exactly what I want them to do without issue as far as I can see, I don't go looking for things that may or may not be there, maybe one day when I've nothing better to do I will investigate this so called touch screen issue - if I find it will it make a difference to my overall opinion of the Z1 - no, will it make a difference to my daily usage of the phone - no, will it make a difference to my overall satisfaction of the phone - no, would it encourage me to sell both devices and move to another manufacturer - no
[Xperia Z1 Q&A, Help & Troubleshooting] jsauce75:
So, as I feared, I spoke too soon. I woke up this morning to a secretly malfunctioning touchscreen. Must have just been a weird coincidence last night. I think this phone is going back Saturday as I am still in the buyers remorse period. Bummer.
[Xperia Z1 Q&A, Help & Troubleshooting] 301stSpartan:
I'm glad yours is ok, but not sure what your post is adding to this thread. If you think we're just searching for any little fault then please, come to Bangalore and use my phone for a half hour. You'll see that typing via Swype is basically impossible and any game that requires long presses or drags on the screen is unplayable. So yes, our daily usage is deeply affected.
[Xperia Z1 Q&A, Help & Troubleshooting] totikk:
I read the topic and I see that most of the problem appears when you touch a metal frame. And videos on youtube show the same. However, the problem occurs exactly when I do not touch the metal frame. For example, the phone lies on a table / bed and I just drive a touchscreen on. Line is constantly interrupted. But if I touch a metal frame, all passes. So I just use the phone without a case. After all, most of the time I hold it in my hand and of course touching the metal frame.

Anyone experiencing the same problem?

I'm just afraid, if Sony will attempt to correct the problem that many (that you do not touch the metal frame) and then I will be a trouble, because now I need to touch it on the contrary ...
[Xperia Z1 Q&A, Help & Troubleshooting] jsauce75:
I have the z1s. It has a plastic frame and I have the same issue. It's not caused by the metal frame.
[Xperia Z1 Q&A, Help & Troubleshooting] RISHI RAJ:
I dont think everybody has same problem.Its cannot have a universal fix,I think Sony cannot fix it.Guess Ive bought a wrong phone
[Xperia Z1 Q&A, Help & Troubleshooting] jsauce75:
I think you're right. This thing is going back Saturday. Think I'll have to go back to the HTC one.

[Xperia Z1 Q&A, Help & Troubleshooting] skandats:
When this happens, I just wipe the screen with a clean cloth which solves the problem. I used to pause while playing games, wipe it and voila! its works perfectly fine! Try and let me know if this works out guys.
[Xperia Z1 Q&A, Help & Troubleshooting] Geoffxx:
I am not racist but I have to ask how many complaing here are from India

I'm doing a survey
[Xperia Z1 Q&A, Help & Troubleshooting] hoezay:
holy shizz, I think the latest firmware update has solved the touchscreen problem ! Before it I was able to reproduce the problem every single time , and now it hasn't happened even once. going to keep testing.fingers crossed. ( firmware .136 )

**UPDATE

It happened again , but just once and when i lifted my finger off the screen and put it back down it worked flawlessly again haven't been able to reproduce it again.let's see.
[Xperia Z1 Q&A, Help & Troubleshooting] shteren:
lets think.... how much is by percentages the population of india from the 7 Billion total?

you can assume a similar portion of the z1 users are indian aswell... now you have your reason... the chienease are not here because they don't know english as opposed to indians who knows it pretty well...
[Xperia Z1 Q&A, Help & Troubleshooting] jsauce75:
Wiping it does work, but it's not like my phone is filthy. The obviously problem is that the phone is a phone that relies on touch input, so the screen is very rarely completely clean. Perhaps they should have thought of this when they were developing the phone. Maybe Sony's recommendation will be to use a mouse and avoid using the touch screen at all costs. Ha
[Xperia Z1 Q&A, Help & Troubleshooting] feddexx69:
Just updated. At first it seemed better touchscreen response. then it happened again, Swype unusable, cuts the drawing line and enters short words..but hey turns out i HAD yellow hue and haven't noticed it, so I got that going for me, which is nice.
[Xperia Z1 Q&A, Help & Troubleshooting] eclyptos:
Are you sure is not the keyboard the problem?
[Xperia Z1 Q&A, Help & Troubleshooting] feddexx69:
As much as I'd like it to be the keyboard, it's not. But I have seen improvements in scrolling. How about your Z1 eclyptos? I remember you had this issue too
[Xperia Z1 Q&A, Help & Troubleshooting] eclyptos:
Of curse but I never used Swype and many report improvements with .136 so I just asking, presumably it's just a Software issue or they try to workaround with the FW. BTW mine still at Sony Center and I don't know what they doing to the phone. Tomorrow or next week I will call them to know when the hell I get my phone back.
[Xperia Z1 Q&A, Help & Troubleshooting] RISHI RAJ:
So we have to keep wet cloth everywhere in our pocket, so that when issue arises we can use the same :D;)

so it's actually dirty greasy fingers causing this problem lol

and he didn't say wet cloth
[Xperia Z1 Q&A, Help & Troubleshooting] skandats:
Guys, I didn't say it is a dirty hand problem! This is a screen issue and might be related to the static chargers that might be on the screen after we use the screen for a while. Just ma guess as wiping it will clear any residue charges on the screen. :confused:

Hello people. After updating to .136 I am unable to reproduce the problem except for a split second yesterday. After almost a whole day of randomly testing ,I havent had the problem at all. If you're still having problems try updating to .136 and follow it up with a factory reset.i really do hope this is the last we hear of this problem, I will keep testing.
[Xperia Z1 Q&A, Help & Troubleshooting] jsauce75:
How do I update?
[Xperia Z1 Q&A, Help & Troubleshooting] darkhole:
Hi

Ok, I have an Xperia Z1, I just updated my phone to the latest update (14.2.A.1.136) released yesterday using Sony PC Companion.

Still same issue, you can reproduce it doing this:

- Open a paint app (anyone, I used Sketch or SkectbookX from Adobe)

- When the app is ready lock the screen

- Touch the screen with a finger and keep it in that way, then use the power button to power on the screen

- Witch another finger beside the one that is touching the screen, unlock the screen.

- When you start to move the pressed finger to draw the line wil be intermittent

I don't know if the problem will be fixed with the Kit Kat update (Android 4.4). I hope so, because the Sony support guy told us that was a software issue and that a software update will be released to fix it.

I don't think that this problem is related to the aluminium border, because as some users said the Xperia Z1S from T-Mobile in USA had the same problem, and that phone doesn't have an aluminium border.

Some people mentioned that using Antivirus software or resetting the phone can help... But that's not true (Please, Android is on Linux, just stop thinking that is Windows). This is a Software issue or hardware, but no configuration issue.

BTW, if we want to trace if the problem is related to hardware we (everybody who post here) should post some hardware information, in my case:

Model: C6903

Android version: 4.3

Kernel version: 3.4.0-perf-g8330588

Compilation number: 14.2.A.1.136

IMEI: 3580910565617XX (last two numbers were hidden)

Serial number: BH90DBYM06

My phone was distributed in Sweden but I'm in Colombia.

All this information about phones wil be compiled on a spreadsheet.

The spreadsheet is this:

https://docs.google.com/spreadsheet/ccc?key=0AoT6dtEg-0QFdEZ0cklKTXN0UlFrTTlWT2tReXVpekE&usp=sharing

You can read all this information also in the Xperia care forum:

If you use this method this will happen even on iphone. I think this issue has been proposed already but was scrapped. You have the problem if this happens on games and when in hand. Especially on the bed and flat surface.

COMPLETLY FIXED!! haha! sony did it, at least for my phone.

just flashed NUT's .136 fw and it's absolutly gone. i've never had problem reproducing the touch screen problem but i simply can't!

I went through 6 Xperia Z1S' before giving up. Love the phone but can't stand the skipping touch issue.

2 of which were in the store without even fully activating it. The T-Mobile rep was surprised, I'm not entirely sure it's a dirt issue or stuff on the screen per say. I think it's a setting.
[Xperia Z1 Q&A, Help & Troubleshooting] darkhole:
Ok, I made some testing, and these steps to reproduce are not right. The «problem» also happen with other phones/tablets.

Please, check this app to evidence the problem, I still got the problem on my phone:

https://play.google.com/store/apps/details?id=ru.tpyxa.android.multitouch

BTW you can also try google maps, zooming in and out and twist. The problem is still there. Or just try to write swiping the finger.

You can compare the Multi-Touch test app on different phones, you'll see the difference.

I already tried the app on:

- Xperia ZL

- Motorola Moto X

- Motorola Motosmart Me XT303 (The only phone with weird results, both touch points are detected but it use a mean to indicate only one touch pont when you put them at the same height or width)

- Samsung Galaxy Ace

- Samsung Note 8

I really like to hear that some users got fixed this problem with the last update, I will try a reset on my phone and see if some config is the problem.

So is it safe to say that getting my z1s warranty replaced with another one is an act of futility? I was going to exchange for the nexus 5, but it only has 16gb non-expandable storage on tmobile. I think the note 3 might be too big and I hate touch wiz and all plastic phones. I might have to get an HTC one even though it is eol. This sucks...
[Xperia Z1 Q&A, Help & Troubleshooting] shteren:
sorry buddy it's working flawlessly here... 5 fingers registered swiping across the screen and it keeps perfect track on all of them....

.136 really did fix he problem for me, but mybe mine was light to begin with... i didn't have serious problems with swiping before .136 only while playing games with the touch screen i occasionly got skipings... now it's all good.
[Xperia Z1 Q&A, Help & Troubleshooting] hoezay:
3 days of testing firmware .136, and my Z1 hasn't had the touchscreen problem at all.. WOOT ! :D I think it's fixed ! ( was able to reproduce the touchscreen problem every single time before this firmware )
[Xperia Z1 Q&A, Help & Troubleshooting] vahdyx:
I'd say keep it. Sony just released a patch for the Z1. I'm sure the Z1S patch will arrive "soon"

I know "soon" is subjective, but the phone is incredible IMO. If you can just deal with it you'll have a damn good phone in time. Just keep checking for updates on the PC companion and keep us informed.

I left the Xperia Z1S in favor of the LG G2 and I still miss the Xperia. I still think it was the best phone I owned to date. Now I'm semi stuck with the LG G2.

I'd say stay strong and wait it out.
