Did you update to .136? If not do it.
[Xperia Z1 Q&A, Help & Troubleshooting] tudy88:
I didnt recive update yet. But i read on net that the problem persist even after the update and even if i change to a custom kernel.
[Xperia Z1 Q&A, Help & Troubleshooting] eclyptos:
First Update to .136 and see. Then get your conclusions. If you don't update you can't say is not working. It solved the problem for me it can be the same for you. Yes, it's not perfect even after update, if you really want find the problem you got it, but I cannot complain now, finally a can use it and play games.

On a side note, I was skiing the other day and I have some of those e-tip gloves. They do not work at all on my z1s. Always worked great on my HTC One. Sensitivity of the screen is terrible on this phone.
[Xperia Z1 Q&A, Help & Troubleshooting] tudy88:
one simple question: all the xperia z1 had this touchscreen issue? i had any chance to solve something if i go to the service center? From what i read The update .136 dosent resolve the problem, just masking, but is there.

Hello,

Im on 14.2.A.1.136 stock and it at first glance it seemed like touch screen issue is gone but unfortunately its not ;(

It's harder to reproduce the problem (it seems like sony was afraid of this method on their forum - /t5/Xperia-Z1-Z1s/xperia-z1-touchscreen-problems/m-p/538981/highlight/true#M15244 - so now when you lock your device with finger on it, your touch screen wont work untill you lift it), but the problem is still there, and is still annoying. Browsing the web is a pain in the ass, whenever you want to scroll you end up opening something and when you are pinching to zoom screen goes crazy. What's more I recently started to have some problems with the system, sometimes i cannot open sms app or type in browser, returning to home screen takes few seconds (and Im sure it's not couse of apps running in the background)

If this is "the best of Sony" then I am sorry to all you guys that bought mid tier devices ;)
[Xperia Z1 Q&A, Help & Troubleshooting] eclyptos:
I can't advice what you should do. I can just tell you my experience. What I know, not all the Z1 have this problem. I got new unbranded Z1 and after a month the issue appear on my touch. I send it back to Sony Center and they send me back the phone after a month telling me the problem was NOT FOUND, do you believe it. Also I give them a new device and it comeback full of scratches. Then my last chance was to update to .136 and I am glad I did. Now the phone is just fine, I can play, scroll all what I want, but is not perfect. What that mean? That mean if i want to find the problem with the touch you will get it. If you deeply try to reproduce it in some strange way it will appear again but only when you use it in strange way to see if the problem is there. On daily use and games, nothing.
[Xperia Z1 Q&A, Help & Troubleshooting] tudy88:
1)so you tell me that after the update .136 if you put on the bed or a couch and do the screen test without touching the phone is hard to replicate the issue?

2) why you accept the device if it was full o scratches?

3) when you was on .290 you got the touchscreen problem even when you hold the device in your hand?
[Xperia Z1 Q&A, Help & Troubleshooting] eclyptos:
Yes, and it is not hard to replicate because there is no problem at all. Never. Test positive all the time.

I was not there to pick up the phone. It was send to me via Courier.

Yes.

Anyone having issues with touch screen after updating then? Or is it just me?
[Xperia Z1 Q&A, Help & Troubleshooting] tudy88:
i just left my z1 at service today. Hope i can get solve this somehow. For me its a hardware issue , no software can rid of this.
[Xperia Z1 Q&A, Help & Troubleshooting] eclyptos:
I don't know. Maybe we all have a hardware problems and the Update just masking, work around the problem on some devices. Just is not clear to me why the update fix the problem on many devices and on others don't.
[Xperia Z1 Q&A, Help & Troubleshooting] tudy88:
i don't pay 500€ + for a device to masking the problem. FIX or move on other brand.
[Xperia Z1 Q&A, Help & Troubleshooting] eclyptos:
I perfectly agree with you. I hope they fix the phone for you because after the problem was gone on mine, I am very happy. Even if you change brand you will not have the same feelings like with the Z1. This phone is just awesome, If I throw it on head of somebody I think I will kill him. :D

Still happening with brand new stock and current firmware

I got a pair of brand new Z1S phones yesterday from T-Mobile and both have this issue. I did a full reset with the Sony PC Companion tool and it loaded the 14.2.C.0.159 firmware. Right after boot, pull down the notification shade, it gets about 2/3 of the way down and then acts as if I let it go and goes up to the top. I'm returning both phones tomorrow and will be getting something else. Shame, really, as it's a nice phone.
[Xperia Z1 Q&A, Help & Troubleshooting] ToledoG28:

Are you using a case at all? Do you notice it ever? Mine is so bad I usually can't even type a 0 by long-pressing the p key on the soft keyboard. It just types a p.
[Xperia Z1 Q&A, Help & Troubleshooting] andyid:
I had my Z1 since November and no case on mine till mid January.

No issues.

Had a case since mid January and still no issues.
[Xperia Z1 Q&A, Help & Troubleshooting] :
I finally got fed up with the stupidity and returned my Z1 I got in November today for a full refund. They tried fixing it 4 (!) times and the last two times they promised me a new one to replace the faulty one. 9 weeks and 4 "repairs" later the issue was still there so I ran out of patience. I got it on November 19th and took it to be repaired December 20th the first time since the .290 update didn't help. After that I've only seen it for a few weekends and then taken it back for repairs and now it's already March. Enough is enough and this really puts me off from considering another Sony device unless I can confirm that they don't have any similar problems.

It sucks because there aren't any other phones with comparable cameras out right now and I seriously need a working device for work and studies so I probably can't wait for 1½ - 2 months for the MWC releases.

Edit: I know this is offtopic but I'm open to any suggestions for a replacement with good specs, memory card slot and a good camera. Maybe in PMs if this is too irrelevant regarding the topic.

Fix coming with Android 4.4 Kitkat update (no timeframe)

I spoke with Sony support for about 20 minutes on Tuesday and they confirmed the issue and that a fix is coming. It will be part of the Android 4.4 Kitkat update for the phone. Unfortunately, there is no ETA for it.

I put together all the information I have in one place on my blog. I can't post a link as even though I've been a member since 2010, I haven't posted prior to this issue. You can find it via my homepage in my profile if you'd like.

I wound up returning my and my girlfriend's Z1s phones due to the issue. The local T-Mobile store said they've been getting other returns as well. I'm bummed as I really liked the phone, even with the dull screen.

[Xperia Z1 Q&A, Help & Troubleshooting] 301stSpartan:
Just want to share my experiences. I had really bad touch screen problems since December that I'm 100% sure is due to faulty hardware and can't be fixed with software tweaks. This may not be the case for everyone.

I first noticed problems like what everyone here is reporting and things like swype became completely impossible to use. Then on top of this, I noticed that there was a thin area running horizontally across the screen which didn't register any touch at all. Not just swype/dragging problems but even just a static touch wouldn't register at all. This is a hardware issue and I knew that now I'd have get a replacement.

Once my travel schedule relaxed, I updated to 136 just to see if the swyping issue was fixed as many here reported. To my surprise it made MUCH WORSE. This leads me to believe that some people here likely have hardware issues while others may be software related. Those who got better with 136 might have a software issue, but after mine got much worse with update, I'm convinced issue was a different.

I was going to replace the phone either way due to the other issue so I did and just got my new device.

My new phone seems flawless so far. I'm amazed by how well the touch screen works and even more amazed that I got so used to my old faulty phone to the point that a working phone actually shocked me. No issues at all, and finally I'm a happy customer who can enjoy my Z1.
[Xperia Z1 Q&A, Help & Troubleshooting] chunlianghere:
i tink i was the same as u. 136 was much more worse than 290. since 136 hav more bugs, i revert back to 290.

anyway this problem will be fix in the next firmware, which is 4.4 kitkat.
[Xperia Z1 Q&A, Help & Troubleshooting] brapicoco:
.136 solved the problem for me and very rarely experience the problem. Hope that 4.4 will truly fix this issue. I'm enjoying my z1 now :p

I don't know If I'm right here.

Have a Touch issues too.

Using the Nightly of CM11. And now about 3-4 day's my Touchscreen hold its position and does not response when I touch another place of the screen, it does not matter running an app or just swipe the Homescreen. Sometimes it helps when I wake up the phone again, but not every time ( placebo effect ? )

Took an Video with my Webcam, sry for the poor quality.

[YOUTUBE]watch?v=MRbWBzEria4[/YOUTUBE]

Using an scratch resistant film over shatter proof. And cleaning the Display does not help.

Maybe a CM11 issues? Flexband? The phone didn't fall or never used it under water.

It's now 4 Months old, if it does it with the next CM11 Updates too, I sending it back.

So, yesterday afternoon, I flashed the last Sony Stock ROM ( 14.2.A.1.136 Generic DE ).

Till now, touchscreen works fine.

Looks like, CM11 Nightly issues, but after 5 Nightly Updates it wasn't fixed, before I flashed the Stock ROM.

Tomorrow, I'll give the latest CM11 an second try. Maybe It was just a corrupt OTA build.
[Xperia Z1 Q&A, Help & Troubleshooting] ABBolle:
I just want to say, that the Z1 Compact has the same issue. At least for some users... Maybe depending which display type is in the phone: JDI or AOU.

[Xperia Z1 Q&A, Help & Troubleshooting] HoTsHoT89:
After trying out various software fixes I finally discovered on how to solve my touchscreen issues - take note that we may have different touchscreen issues in question so if mine relates to yours you can give it a try. My phone uses a bumper case - so no direct contact with my hands here.

My problem with the touchscreen was that when you tap and hold at a point it would erratically jump to adjacent areas around your finger and back, making single taps at a small location a pain. I first realized this issue gets worse and worse when the screen protector accumulates oil and fingerprints, and it would only happen at certain locations of the screen - wiping it with a cleaner would cause the issue to momentarily go away, but after prolonged usage it would happen once again.

So there was a day when I did an experiment - I wiped the screen squeaky clean to strip the dirt and oils off, but I left my fingers oily. Held down the screen at the same location and it exhibited the same problem. Then I recalled on the first few days of using the phone, I didn't have a screen protector on, so I was left with another area uncleaned - under the screen protector.

I removed the SP, stripped the surface of any oils and swapped to a new SP. Till today, no issues - give it a try.
[Xperia Z1 Q&A, Help & Troubleshooting] scesarin:
Don't we lose warranty if SP is removed?
[Xperia Z1 Q&A, Help & Troubleshooting] HoTsHoT89:
I meant my own SP, not the shatterproof film that comes with the phone.

If It's that bad, get a replacement. Warranty. That's what I did. It's a hardware issue when it gets that bad, so if you have the issue still and it's serious then get a new device. No warranty? Well, then, should have bought one with a warranty bc the phone has been out less then a year and you should get a 1 year warranty when buying.....

Maybe related with Sim card?

Hi everyone!!

I have just called to Technical support of Sony Mobile Spain to ask about the touchscreen problem. Because i have send to them 2 times, and he told me, probably the problem is not related with the phone, probably with the sim card.

I think it's very difficult the sim card provoke this problem.. in my opinion. But i'm trying.. i take out the sim and i'm texting a lot, i will take a probe time and i will write here the result. :)

It's possible the sim card are problem?? what do you think? have anyone tried to change the sim card?
