[Xperia Z1 Q&A, Help & Troubleshooting] Lexrg:
the first z1 i had was the one with less issues, very very hard to reproduce it affected me like once in a week, but i thought was a defective one and i changed it, the second one whas sooooo easy to reproduce the touch issue, almost imposible to use with a case on and the third one was as bad as the second one, the last one not too much but i was tired of the phone problems allready, so i changed it for a note 3, the saddest part is that in note 3 u can controliso and EV and disabling Image stab for night shots got me better low light pics that in my xperia z1 and that is the moment when i got very dissapointed of sony. i really hope ur phone to be ok but for me at least every z1 my carrier had, was deffective. 5 or more people were asking for a doa in the days i was in my carriers office.

if u use ur phone naked and always touching it with ur hands is not gonna give u problems at least they didnt to me but as soon as i used a case on them i got skippings all the time, sadly for me i dont like to go arround with naked phones i allways use cases and i have a restorant so somethimes i cook and with filty hands i need to use it on a table and thats when it affected me a lot.

At first I was using it naked. Now I got a generic black rubber casing on it since mid December and no issues yet.
[Xperia Z1 Q&A, Help & Troubleshooting] brapicoco:
So is it the touchscreen digitizer problem? or some other parts of the phone are shorting out? any temporary remedy for this one? I always use my phone naked since I dont like cases. Happens to me when gaming always even unlocking the screen and during browsing.
[Xperia Z1 Q&A, Help & Troubleshooting] Banwell13:
Just an idea

I use this method as I have removed my ASF, you guys are having issues of the opposite to me, so why not trying changing the touch.filter.level from 2 to 1 there by increasing sensitivity. Might not work but I'm guessing it's worth a shot. I would keep the pressure to 0.1 though as I don't see this changing to much for you. Let me know if it helps. Just a thought.
[Xperia Z1 Q&A, Help & Troubleshooting] Fox_Soul:
after test 2 devices and another 3 in shop, I only can say that Sony has created the most good looking and potent smartphone... With a lot of issues. The last i tested in shop has the screen in pink... This smartphone is totally a Joke from Sony.

I will sell it in a few days and buy the LG G2.

Good Luck with the problems guys. Use your warranty and dont stay with a issue in your top phone.

Yes, you are lucky to not have it. That how supposed to be for all Z1 users.

It's still a good option to try, don't you think?

Same here Man, sometime Pattern skipping, sometime scrolling pages skipping and the joystick stop working in the middle of the game. At this time no real solution, the only one thing you have to do, try all the options but if you are not rooted you can't solve the problem. You asking for a solution but the solution can work for me but no for you and nobody will tell you it's working or fixing 100% the problem. There is no other way than try by your self.
[Xperia Z1 Q&A, Help & Troubleshooting] brapicoco:
my source just tried the codes and still it does not work for our issue.definitely a hardware problem
[Xperia Z1 Q&A, Help & Troubleshooting] ascariss:
So my screen problems began on the 2nd of january with erratic behaviour and presses and touches not working at all. At times it works fine, then all of a sudden it goes bonkers, like someone is touching the screen with no actual touching of the screen. I did a full reset to factory settings, this seemed not to have fixed it either.

I hope this is software and not hardware based, otherwise I am going to have to get a replacement :/ If I do, I might just sell the phone and wait for something else :/
[Xperia Z1 Q&A, Help & Troubleshooting] eclyptos:
Mine was fine for the first month, after that the issue show up. This is a kind of joke from Sony. We still don't know what the problem really is. Many speculating about Hardware but no confirmation about that so we still waiting for a clarification.
[Xperia Z1 Q&A, Help & Troubleshooting] ascariss:
I thought it was an app or virus, but I didn't install any recent apps so definitely was not that. What worries me, if this problem will get worse and at times I won't even be able to use the phone :(

I hope this is software based but I feel it is not. Sony has a tendency to mess things up, usually something is wrong with their products, so far I've only had good products from the walkman group and camera group.
[Xperia Z1 Q&A, Help & Troubleshooting] eclyptos:
Actually, after I update to 4.3 from 4.2.2 the issue with my touchscreen get worse. So I asking my self, it's hardware or software? Did I damage the chip of the touchscreen after flashing?
[Xperia Z1 Q&A, Help & Troubleshooting] shteren:
ok quick update, AFTER A MONTH i got my case from aliexpress, i mennaged to throw on phone on the floor twice in that time, lucky me other than a small dent in the frame nothing happend.

so anyway i've got this case:

http://www.aliexpress.com/item/New-Free-Shipping-TPU-Soft-Back-Cover-For-Sony-xperia-Z1-Honami-L39h-Case-One-Piece/1435252636.html

simple cheap tpu case, actually fits perfectly and feels good, i'm quite satisfied. so the pounch line is, i can berely reproduce the touch problem with the case on. i always got it when i touch both the frame and the screen, but now i can't without really trying hard.

so i think it can actually solve day to day issues, i'll try to see if it interrupts gaming, but i think it's good to go.
[Xperia Z1 Q&A, Help & Troubleshooting] ascariss:
Well it seems my screen is either completely ****ed up as in the touch layer broke or the phone is poor effort from sony regarding quality control. I will try to upload a video of what is happening, but I can't seem to reproduce it all the time. At times the screen just becomes unresponsive and I cannot use it at all, things start to go haywire with menus opening and the device clicking and selecting various menus or items.

I have no idea what triggers it, but if it continues like this all week long next week, I am going to go and try to get a replacement on the spot from the store.

speaking of warreanty issues, anyone tried to get one fixed or returned in poland? I feel this would be a lot more complicated than in other countries.

It is probably a defective unit, changing hte launcher fixed nothing, as did a full factory reset. Oh well, probably will have to return it for a new one, but I feel that will be a bit more complicated than what I was used to back in Canada.

Sorry Bro,bout your phone is completely faulty.mine doesn't have any problem...
[Xperia Z1 Q&A, Help & Troubleshooting] :
That is definitely faulty. Take it to either be repaired or to get a replacement.
[Xperia Z1 Q&A, Help & Troubleshooting] Kirkymole:
Tried every method of reproducing the fault but my handset just will just not do it. So my Z1 is safe it would seem.

I'm running. 290Fw with Doomlords kernel. Unlocked my bootloader and rooted with dual recovery installed. I have around 100 apps installed. Exposed framework and a dozen or so modules affecting virtually every aspect of the handset.

It always lives (aside from experimenting to get the fault to show) in a silicone case and always charged via the dock, never the USB port.

I hope that helps someone somehow figure out what's going on.

[Xperia Z1 Q&A, Help & Troubleshooting] brapicoco:
Whoah I saw the vid and yours is a lot worse than mine. Still no remedies for this issue.

I tried placing my phone in a hard case and plastic and still the **** problem is there
[Xperia Z1 Q&A, Help & Troubleshooting] Riemen:
Maybe sometimes the touchscreen issue is not an issue of the phone one.

I was sure my phone had this too. In my case touchscreen worked without any problem when touching the aluminium frame. I tested it several times and never had any issue during normal use. But when the phone was lying on an insulated ground and while not touching the frame it was completely unusable. The screen only recorded very short swipes and never responded to any single touches, e.g. pressing the softkeys.

Now I realized, the problem was the screen-protector!

I placed the phone an an insulating surface and verified the screen didn't work properly as expected. Then I removed the screen protector, repeated the test several times an now the touchscreen worked completely normally! After reapplying the screen protector, the problem was there again.

The protector was based on a Vikuiti DQC160 foil from 3M which I had applied from day one. My theory is that, together with the Sony scatter protection film, the screen was insulated to much, so that the capacity changes during a touch are not recognized anymore. While touching the frame, the capacity change could be stronger, so that it will be recognized again.

To conclude: If you are facing any touchscreen issues and have an additional screen protector applied, you should remove it and see if the problem is gone now.

I have to apologize for blaming Sony to sell a defective device. At least in my case this is wrong.
[Xperia Z1 Q&A, Help & Troubleshooting] clutrz:
For me the issue with the touchScreen only happens after around maybe 24 hours and then starts getting progressively worse. A reboot fixes it straight up for me though so I'm hoping it is software.

[Xperia Z1 Q&A, Help & Troubleshooting] eclyptos:
Sent back to Sony!

Yes, I did. Why should be complicated? It's not.

This is 100% faulty device.

[MENTION=919839]Riemen[/MENTION], my friend, there is no way in the world that a screen protector can do such a thing.

It's a device issue anyway, with or without the screen protector and I don't even took it off, I just sent my phone back to where I brought it and I showed to the girl all the issues and I spoke with the Manager of the shop about this and no problem at all. They will send the phone to Sony Service.

I hope they will replace the device. I will let you know what happen to my device and if this is a hardware issue or software, if is software my phone should come back with some update or fix, if I get a New one it's a hardware problem.
[Xperia Z1 Q&A, Help & Troubleshooting] brapicoco:
wow that's good, here I will be charged for more than PHP 10,000 for the repair and parts and never replace the unit. 43 PHP = 1 USD

It really is crap here since according to the service center, Sony has no international warranty for its devices.
[Xperia Z1 Q&A, Help & Troubleshooting] eclyptos:
Sony do not cover the warranty in your Country? This is really weird.

Is not the Shop where you brought it who want charge you?

I was thinking the best way for me is give a shot via warranty.
[Xperia Z1 Q&A, Help & Troubleshooting] Riemen:
I don't say that a screen protector causes all the problems you have with your tochscreens. But it was the cause for me. I still can only speculate why this happened, but I have the proof here in form of my Z1, that now, without a screen protector, works without any issues.

Also my touchscreen problem was a little bit different from what some people here are telling, but as it was also connected to touching or not touching the metal frame of the device, i assumed it was caused by the same problem.

I just wanted to hint that an additional screen protector could also be the cause of touchscreen issues on this phone and maybe for a little number of the people here this could be the solution.

For all the others I think there are only 2 ways: Hope for a software fix or send the phone to Sony service or back to your dealer (if you have legal warranty in your country) and let them repair or replace it.
[Xperia Z1 Q&A, Help & Troubleshooting] ascariss:
Because this is poland and things are much more complicated than back in canada regarding warranty and returns.

at this moment, the dude at the store told me 4 weeks minimum to get it fixed, so I was going to call Sony, but it seems that my screen issue went away for the time being and I will not be sending it in to get it fixed, if it begins to **** up again beyond the point where it is usable I will call Sony and send it to them.
[Xperia Z1 Q&A, Help & Troubleshooting] brapicoco:
I only have manufacturer warranty and if ever there is a hardware fault and parts are needed they will charge me since I dont have the Sony Warranty. I just spoke with a CSR and they claim that there is no international warranty for sony devices.

Im stuck now with a crappy z1
[Xperia Z1 Q&A, Help & Troubleshooting] eclyptos:
Mmm....I don't know why in Poland should be different, what exactly do you mean?

I asking because I brought mine in Poland and, like I told you, I returned to the store where I get it and they told me they will send the phone to Sony to repair. They said can be two weeks to no eta, Sony will decide if repair or release a new one device. For conclusion when they will receive the phone from Sony they will send it to me by post signed by, because I do not leave in Poland. I paid for the shipping only, to return the phone to me, so I don't know where is the issue of the service.

---------- Post added at 05:36 PM ---------- Previous post was at 05:27 PM ----------

If you paid a full price you have to have the warranty. If the store sell legit devices for you country you should have warranty. They told me the same when I brought mine about Manufacturer Warranty, it's the same as any warranty but saying that the store telling you, they don't take responsability but the warranty should cover the device. To me seems like something wrong there with your store. They probably selling the devices imported from other countrys.
[Xperia Z1 Q&A, Help & Troubleshooting] 301stSpartan:
Sony is the manufacturer, so how can you have the manufacturer warranty but not the Sony warranty??? :what:

Also, there isn't an international warranty in the sense that you can't claim warranty in a country the device wasn't sold in. But if you bought a legitimate phone in your country and try to use the warranty in the same place, in what way is that international? I think the above poster is right in that you may have bought a phone that was imported rather than one Sony released in your country. In this case, I'd flip out on the retailer if they did that without telling you.
[Xperia Z1 Q&A, Help & Troubleshooting] brapicoco:
It's very evident that they got the phone from other countries since the firmware running on my z1 is SG and when the time I bought the phone, z1 is still not hitting the PH market. So if the store got it from SG then parts should not be charged if they will be using the manufacturer warranty but not. I'm being charged for parts.

Moving forward, I will not buy anymore from any online store. Forget the cheaper price and just minimize the risk. online store prices are tempting since the SRP is PHP34,000 and I got mine for just PHP 25,000

Back to the topic, Service Center claims that they have a touch panel calibration tool and if the problem was not solved through that then it is a hardware, so there really is a calibration tool that is not shared to us users by Sony

Well, I have this issue as well. The difference is that I am using a Z1s on tmobile USA. This model is almost identical to the z1, but it has plastic around the sides instead of metal. That being said, gripping the phone firmly on the sides definitely increases the issue. I also use Swype and it occasional starts acting up on the right hand side of the screen. Right in the area of the "p" key. I'm going to call tomorrow just to get it on my account that I am having problems. I think there is enough evidence on this forum to tell me that swapping this device out with a new one won't fix the issue. I'll probably patiently wait a few weeks for a software fix and then exchange it for a different model. Did anyone else notice the problem goes away for awhile by just turning off the screen and then turning it back on?
[Xperia Z1 Q&A, Help & Troubleshooting] brapicoco:
yes, the problem goes away for a few seconds if you off and on the screen. It seems that the screen is overloading and cannot get the right touch responses. problem also vanishes for a few seconds if you lift up your finger and start touching the screen again.
