My problem is reduced by replacing the screen guard on top of the asf, but problem occurs more when touching the upper left so it means when gaming.. I hope we can find a solution for this since sony failed us big time

Hopefully it can fix the touch issue...
[Xperia Z1 Q&A, Help & Troubleshooting] 301stSpartan:
Thanks. That's good to know, but it doesn't say that this bug will be addressed at all. It only says the update is meant to fix some bugs but doesn't say which ones. The list at the bottom isn't a list of bugs the update will address, it's a list of all bugs currently reported.

In my case, I don't think software will help my touch screen issues. I'm pretty sure it's hardware. Especially because I've now noticed that my issue is also related to where on the screen it is. There is a certain area where it almost always fails, while it works mostly ok on the rest of the screen. To me, that indicates hardware issues.
[Xperia Z1 Q&A, Help & Troubleshooting] eclyptos:
I know is a difficult situation and someone have worse situation than others but this mean they are aware about this and maybe still some hope.

Do not tell me if the update come out you will not try? ;)
[Xperia Z1 Q&A, Help & Troubleshooting] 301stSpartan:
I'll try updates once they can be rooted. But I'm 99% sure this is hardware related so I'll be getting a new device the day I'm back
[Xperia Z1 Q&A, Help & Troubleshooting] feddexx69:
I'm not giving up on Sony, at least they're showing some kind of awareness, they fixed the BL bug, my bluetooth bug, WiFi range..and the phone itself is just gorgeous..but if i were to use it for gaming, I would be extremely dissapointed..right now it's the swype feature I'm missing, otherwise it doesn't affect the overall experience..and again, on 4.2.2 I had no problems once I applied the screen protector

[Xperia Z1 Q&A, Help & Troubleshooting] brapicoco:
Can't see the thread, I think it was removed.
[Xperia Z1 Q&A, Help & Troubleshooting] eclyptos:
Yeah, they removed it because the source of the information given was non 100% confirmed, was from XperiaGuide, not official. There is under testing or something like that a firmware which will solve most of the issues and 1 in particular a Touch Screen. Probably is not official because was not on Sony Webside and no confirmation of his relased. But actually this rumors are a good news because that mean something is moving in this direction so maybe we get a update to solve the issues, but no eta.

You're lucky. But mine used to be the same way and essentially over night became basically unusable.

Hope yours doesn't do the same, or if it does it will at least do it while your warranty is still good.

Best of luck. I assume you had no problem convincing them to replace it?

[Xperia Z1 Q&A, Help & Troubleshooting] hoezay:
Yea, but only because I've been making a big deal about it on Twitter and showed them the video I made of it as well. http://youtu.be/44F_w8tCHHQ ( also I had given them hell over initially getting a z1 that had a defective yellowish display, which they replaced. ) I suspect they're not as accommodating with regular customers.
[Xperia Z1 Q&A, Help & Troubleshooting] shteren:
my touch problems aren't that severe, i can defenetly use pattern unlock with no problem on any surface, i usually come into problem when playing games for a while, leaving the touch screen and touching again solves it immidietly.

my opinion is that all z1 phones have the same slight problem, most people didn't bother to try and reproduce it, or don't play games like us so they didn't notice it...

i can reproduce this on sketch but it's tricky.
[Xperia Z1 Q&A, Help & Troubleshooting] Lexrg:
Rub it to any screen it will go crazy im 100% sure
[Xperia Z1 Q&A, Help & Troubleshooting] brapicoco:
My z1 goes crazy when placed on the bed overnight and on my pocket but after playing games which are annoying due to the touch problem, eventually the issue seems to be gone. WTH? I'm really sick of this phone and I can't get a fcking replacement!

..they didn't said if the problem will be solved in that way, sensitivity can help for sure but for unresponsive touch screen I don't know.
[Xperia Z1 Q&A, Help & Troubleshooting] brapicoco:
I can attest that this is a hardware problem since I have done the testing myself in multitouch, touch will respond if you touch the frme however, when you drag your finger across screen still loses touch.

I'm giving up on this crappy unit and I'll just save money again since I can't get rid of this stupid unit and no person in this world will buy a unit with defect.
[Xperia Z1 Q&A, Help & Troubleshooting] negrobembon:
This is definetly hardware related, cause only certain devices have it and seems unfixable by software so far

I tested it and i dont have it, Z1's on my Local Sony store dont have it either so must be a batch issue
[Xperia Z1 Q&A, Help & Troubleshooting] shteren:
What batch then?! People from all over the world complain about it, different serial numbers, different origins... If it was a batch problem you whould expect to see some connection between them...
[Xperia Z1 Q&A, Help & Troubleshooting] negrobembon:
I could say that its a manufacturing defect that happens at random or that maybe Z1's develop them over time or that Sony uses different digitizers among Z1's or that its just a firmware issue but those reasons are illogical

This issue is very hard to explain but i tested like 8 of them on another store including mine and asked a few people i know with Z1's and none have this issue

The only thing all these devices have in common is that they're all C6906
[Xperia Z1 Q&A, Help & Troubleshooting] Riemen:
I habe touchscreen issues too. Luckily for me the problem only occurs when I don't touch the phone frame, for example when it's lying on the table. When I have it in hands and do touch the frame, everything works well, so I can live with it.

As this occurs only from time to time, even if not at hand, it still could be some kind of a calibration problem.
[Xperia Z1 Q&A, Help & Troubleshooting] eclyptos:
Exactly.

We are to many with this problem, I can't believe they put a device with hardware problem, we experience this issue in different part of the glode, it can't be wrong batch.
[Xperia Z1 Q&A, Help & Troubleshooting] brapicoco:
This is a hardware problem since it deals with the grounding issue, when my phone is laying on a rubber surface (our sofa) touch screen really goes nuts, but using the multitouch test I have placed my finger on the screen (issue was reproduced this time) no touch was recognized but when i touch the alu frame, screen begins to recognize my touch. However, when I move my fingers across the screen it's clearly seen that there is a discontinuity between the touch.
[Xperia Z1 Q&A, Help & Troubleshooting] shteren:
It still could be software solvable if by any chance our screens are getting too high voltage so they need grounding, perhaps due to a bad resistor sodtware can fix this... Idk enough about how modern touch screens work though... So just speculating
[Xperia Z1 Q&A, Help & Troubleshooting] Geoffxx:
in that first video it's two different tests I believe, the first one is single point and the second is multi - could be wrong though
[Xperia Z1 Q&A, Help & Troubleshooting] eclyptos:
I just can't understand how this can be. A grounding problem for a touch screen, first time ever made a such stupid mistake form a company who have 100 years of experience. I know you are disappointed and me too, I can't just accept it can be in that way. For something like that Sony should be out from the market today.

BTW- the grounding thing is the first thing what you learn in electricity...so just saying.
[Xperia Z1 Q&A, Help & Troubleshooting] Geoffxx:
Sony's touch screen tech is no different to any other out there - some things are standard across the whole range of manufacturers including the Digitizer - there may be subtle differences but the general mechanism is the same - they maybe even all buy from the same supplier

we have seen that Samsung use Sony Camera - Sony use Samsung memory chips - they all use qualcomm cpu - do you think Sony and Samsumg design their own digitizer - modem - network chip - battery etc etc
[Xperia Z1 Q&A, Help & Troubleshooting] eclyptos:
I know its a marketing and Crystler, Chevrolet, Dodge are all GM and its a globalisation move.

So if still there same standards and the digitizer are from some supplier why Sony have touch problem and others not with same product?

You just saying this like it will be a software problem only if all are the same.
[Xperia Z1 Q&A, Help & Troubleshooting] brapicoco:
I'm really frustrated about this. If this were a software problem why dont others have the same problem? Technically we're running on the same version. Hardware - if it is not hardware, just why is the touch screen which does not register touch in the multi touch test begin to register touch when the alu frame is touched or placed on a surface where there is sufficient grounding.

Sony would not even acknowledge the problem so this will not be fixed.. sadly..
[Xperia Z1 Q&A, Help & Troubleshooting] hoezay:

guys i have semi news. i just installed monx rom, i have UL but it's for both UL,BL i noticed in the display settings he has an option called "glove mode" no idea where it came from, didn't notice it in any other xperia rom, but it makes wonders lol.

i tested the touch with the option off and i had lots of skips, once i turned it on i could berely reproduce it, i did eventually, but on a much lower frequency.

so i say again, IT DOES NOT SOLVE IT but it might help a little, give it a try, [MENTION=273310]monx®[/MENTION] thanks a lot for your great work and rom, looking forward to v3c, can you please tell us where does this mod come from?

I had an xpera z1 i spend near to 4 days in my carriers office in Mexico for apliying warranty i got my phone doa 3 times and all 3 have the same issue easy way to probe is a static hardware issue is to use cotton sheets rub the phone and use pattern lock with and without a finger touching the aluminium frame. glass an aluminium are the best static conductive materials and im 100% sure as an electronic eng. That as more static the phone is xposed more will be the damage and more easily it will fail i have 3 hours of video testing i have analized them and is really sad from sony to have a mayor design flaw like this static is number 1 enemy of electronic devices it creates currents in mobos and chips that are unwanted i changed my last z1 for a note 3 cus my carrier rep got mad because sony didint accept the doa touchscreen to them so they are losing money even the phone got hidden in the store behind decoration cus they dont want to sell it anymore they told me that that was not the only issue they got lots of doas with cracked screens black screens yellow hue tint and lots of touch screen issues in thevtime i spent there i saw 5 people claiming doa on touchscreen also and the saddest part is thst even with 257 firmware i took pictures with my note 3 as good and even somethimes better with my note 3 abd un low light just needed to disable ois and use lowest iso to reproduce the low light pics i was very proud with my z1 never buying sony again.

It's really good in other countries that they can replace your Z1 here in PH as long as the retailers have sales then it's okay even if the product is faulty and they know it. After sales experience is terrible.

When using the multi touch tester to reproduce the issue, I noticed that when using two fingers or more, there is a single phantom touch that is registering. definitely this is a hardware issue

[Xperia Z1 Q&A, Help & Troubleshooting] 301stSpartan:
You said before "there is nothing wrong with the touchscreen" NOT "there is nothing wrong with MY touchscreen." Now again you're trying to defend the phone against having an issue just because your unit doesn't exhibit it. You think that the first thing we wouldn't try is to wash it and our hands? If you read the forum you'd see discussions on washing it.

We aren't here just trying to complain for the sake of complaining. My phone has a very undeniable and high impact issue. I'm glad for you that yours doesn't but if all you are going to contribute to this thread is denying we have issues and calling us complainers then please just don't waste our time and stop posting here.
