Z2 touchscreen defect - Xperia Z2 General

Hello,
I've just created this new thread to inform you about how my Z2 is broken after two weeks of use.
Today at noon the touchscreen started to do some unusual things, I wrote some messages and I recognized that I wrote multiple letters when touching just one, not one aside the tapped letter but at the other end of the screen.
I wondered how that happened, tried again and again, restarted the phone, nothing changed.
At home I called sony care to ask if anything like this was already known, they just advised me to "repair" the phone through pc companion.
Now I can say that nothing worked and I'm sure it's a hardware defect, by experience I would say it looks like water damage to the digitizer/touchscreen controller.
The flaps were always closed except for charging at the bedside table and I'm sure it didn't rain there.
I will keep you posted what is going to happen involving warranty and xperia care.

now I was able to use the manage attachments button, must have been an internal error, thought it was spam protection, too...

I had the same problem, after two weeks too. I got a new one, but now I'm scared...

This also happened to me when I'm texting, it inputs multiple letters. I think this is a software issue as it happens after making a phone call. I changed to TouchPal keyboard and it happened less. I think the Xperia keyboard has bugs as well. But it rarely rarely happens and I can't duplicate the bug.

Don't know what causes it, seems software related to me. Turn of the screen and turn it back on worked for me. Happened just once...

Lucky for you, problem persists at the exact same spots.
Since yesterday the touchscreen went full rogue a few times, "touching itself" everywhere for a few seconds.
Trying to change it at the shop of my provider today by implied warranty.

Check your screen with this app:
https://play.google.com/store/apps/details?id=com.easylabs.multitouch&hl=pl

Got the phone to my provider this afternoon, the shop assistant examined the device extensively and was pleased by getting informed about the older batch numbers that have some issues (mine was a 14w17 with off center camera and flash).
He started to write down contact details and a description of the failure.
Then he got to a support guide for checking the device before accepting it for warranty, in this guide there was a step to check the wetness indicator beneath the sim card slot...
Suddenly "ohhh...", he said the indicator turned red, i looked at the spot that looked to me like the indicator and said, ok, yes, seems like you are right, ****...
He said that he is very sorry but he can not accept the device like this.
I went out, knowing that he is not to blame for this, called xperia care and was really upset, asked for the nearest xperia care partner to do a water-proof test.
The woman at the hotline asked why I would want to do the test, I answered because the touchscreen is defect and the guy at the provider store said the wetness indicator went off.
She answered that the Z2 has no such thing as a wetness indicator, at least not one that is visible from the outside, the thing you can see is the hardware reset button and the pcb.
Went into the store again, went through all the steps and got a 1:1 change of the device, the shop assistant was amazed that I get a 1:1 change, that would nearly never happen.
We agreed that it may be that Sony informed vendors of faulty batches so that they get replaced without hardware checks and his support guide was an old version of the Z or Z1 because the device is still too new.
I'm happy that I get a new device without any more hassle.

So how is the screen of the new unit?

They would have changed it directly if they had a device in stock, they ordered a new device directly so that I hopefully get the new device on friday.

I have exactly the same problem with my Z1 since i upgraded to 4.4 and whats bad is that its even present in 4.3 when i downgraded. Before upgraded to 4.4 i never had such an issue, its very annoying!

Sorry for replying this late...
Got a device out of an older batch, it's a 14w15, everything is good except camera displacement.
I think the vibration in this device feels a little weirder not as good as in the last device.
I even got an unbranded decive, no magenta t at the startup and less apps to deactivate.
Keeping it and hoping that it lasts the next two years.
Thanks for your replies and support.

defective screen?

my imagio screen is tweaked I can see a little fluid in the screen and it will not respond to any touch. Did hard reset twice but no change. I have to bring it in tomorrow to a store, cust service was no help said they may charge me. At 37 days now this blows.
should I remove cabs before I go to store for warranty? even though the defect is a physical issue?
A hard reset should put the phone back to the factory software state unless you mean a storage card, but then you should take that out before replacing it since that's your own. =)
they are replacing it, I didn't undo my changes before I went in to the store. The guy there said I didn't have to. I have to wait to have it shipped from warehouse-no store stock within 100 miles. Maybe by Monday? I can only accept phone calls with it.
I had the same thing happen to me yesterday. I noticed my screen wasn't responding very well in the center, then I looked closer and this is what I saw

Sending it back to Verizon when my replacement arrives on Monday. Completely a hardward problem
yep that's it
Did you notice your screen not responding as well?
Just noticed I have it as well.. No issues with the screen response though.. I wounder if I should take it in anyway just to be sure something doesnt happen
leads right into not responding at all. I guess the fluid between the layers bleeding out. I think the capacitive screen responds to the stylus when the layers make contact?
started having issues with tje touchscreen.. took it to the store and the first words out of the reps mouth wad "what did you do to it ?"
lol...
then he says that it is normal to have the colored swirls like in the picture posted and that it wad from the oil on my fingers.. lol again.. at that point I say that none of the display devices have this and I showed him how the scrolling jumps around on the applications list..
he ordered me a new one and it will ne here in two days...
anyone else having this issue?
Had the same thing happen to me, they had to send me another phone the other day.
jeez.. the typing really shows how bad the screen has gotten..
Wow, I just had the same problem. They swapped it out for me and told me this "wasn't" a known issue with this phone.
same thing happened to me...
I was outside in the freezing cold last weeek and tried to use my phone. The screen was literally frozen... the phone was not locked up, but the screen would not respond. (The buttons would work, but unfortunately I was trying to call someone other than the last person I called so I was out of luck. Found this thread and realized mine had the same problem. Took it into the store and got a new one in the mail yesterday..
This might be a coincidence but I first noticed this right after I installed a screen protector - one of the vinyl ones that you wet with the supplied liquid before putting on...
me too
I had to return it too... I could see fine hair lines showing up more and more everyday... got a new one... next day some lines started to appear... It is winter and I think exposure to freezing temps is bad... I was warming up the car and put the phone on the passanger seat, I forgot something and went back inside the house for 5 mins.... the inside of the car was freezing the I grabed the phone and it felt VERY cold too... I was like "damn!" that's when the new line showed up on the second NEW phone....
Looks like Newtons' Rings to me
Hi guys, we've had similar complaints in the Blackstone forums. I think the general concensus there is that these "Newtons Rings" are due to delamination of the screen and digitizer. Looks like i'll have to add this to the Imagio Wiki as well.
On the blackstone there's mixed signals as to wether or not it's a "known issue" from HTC as only certain regional HTC repairers will replace it under warranty.
Both the image, and the descriptions you guys are giving says to me it's Newton's Rings. If you're getting them replaced under warranty then you're lucky
this same thing just happened to me 20 minutes ago! I am going to the verizon store after work I am glad i have a years insurance on it!!!
Just like everyone else, I had the same thing happen. VZ got me a new one in 3 days... Must be a manufacturing defect.
they sent me an ozone as a replacement and i called them up and she said they were all out of imagios and tp2 and that the ozone was a fair replacement and i told her i already had one and its not even close to the cost that i paid for the imagio anyway i got no where with the customer service and i went to the corp store in town and got it settled but it wont be here till friday which sucks!!! this will be number 3!
Maybe someone can find a site that sells screen and digitizer replacements.....

Warranty situation, help appreciated!

hey guys, I need some advice on what to do. Situation as follows:
1. Not easily shown and randomly occuring screen defect, color patches appear, blue bands dance around. (as in, Fault? what fault?! like i had with a different product)
Post4 -only way to reproduce the problem, does it happen to you?
2. Bought HD2(Leo WWE UK) through Expansys china , as I'm in China atm, expansys is located not in my city so I can't reproduce the problem to them myself (no idea where the actual repair center is, expansys isn't picking up calls, and theres no "htc china").
3. Returning back to Australia in 2 weeks, what happens to the warranty?
Just a few obstacles it seems.
Could anyone share some knowledge? would mean a lot for me. Thanks!
i don't want to scare you mate but i've read there are chinese fakes on the market, it's possible you've got one. i suggest you contact htc australia and explain your situation, there must be a way they can help. good luck!
If you got it from Expansys, I doubt it's a fake. I think you're just gonna have to persevere in getting touch with them, even if it's after you get back home. The warranty will still stand, but you'll probably have to send it back to Expansys.
It clearly needs replacing from what you've described.
johncmolyneux, think ur right, called expansys HK (not cn) they said i'll have to go through them, can't go htc directly. so no possibility to take to a htc authorized repair place in Australia right?
..wonder if I can send to Au eXpansys
the bigger issue:, on its own myHD2 goes retarded infrequently, like every 2 days, for 1/2seconds to 5seconds only. so i'm worried about them not seeing the problem and not fixing it.
wonder if it happens to all HD2's actually, sorry to sound sadistic, but below is the only way I can make it happen. otherwise the phone does it on its own every now and then.
Only way to reproduce it is by supporting at the front, on both sides with my thumb at TF3D slider height, and then pressing in from the back around the center also at slidebar height (tho sometimes a little more pressure is needed).

It's good that you can reproduce the problem. I tried it on mine and it didn't do anything unusual, so it's definitely not all HD2s that do it. (Maybe it's only mine that doesn't do it )
I don't know if the guy will be able to reproduce it, probably try at few times and say theres nothing wrong. ><
reckon Au Expansys can take it in?
how long does it take ususally?

I have no idea mate. You'd best ask expansys those questions. I can just imagine the first response to the pic you've posted though... "Those blue lines are on the wallpaper" lol.
Good luck getting it replaced.
sigh, its hard to reproduce it, you can use it for an hour and not have the problem show.
they said the process is around 2 months. i might just live with it. usually, i press somethin on the screen, it goes away
2month is a long time for high tech stuff!

2 months to get it replaced??? That's ridiculous. Surely that's not right?
apparently it goes to HK expansys (im in sh) then they send it off for fixing. they mentioned 4-8weeks.
The problem doesn't occur all the time, so it annoying to not have it for 2 month and have it back un fixed.
HOw long should it be normally??

Desire HD Screen Issue

Hello all and thanks for reading my thread.
I have searched high and low for this same issue, but found nothing similar anywhere unfortunately.
I have recently noticed that at all times, the screen seems to produce some horizontal lines which flicker often ... I am finding it hard to explain the problem itself, but I have not dropped the phone nor hit it or w/ever.
All I can think of is that I played a lot of this one game on it and it could have affected (overheat?) the GPU or something along those lines...
I am really not sure, but bottom line is that now I see all these issues on the screen, and camera and some games are off limits to use as they look very confusing...
Anyone has any idea what it could be?
G
Could you provide a screenshot?
It does sound like a hardware issue. I would send it for repair. They might even replace it. Maybe you could take a video of it happening.
(I assume you tried uninstalling the game and it didn't solve the problem. If your CPU is being overclocked try resetting it back to normal.)

Are screen issues/hardware issues fully covered by warranty? As I talked to an HTC support dude and all he said was we can book a repair and if it's not covered by warranty we'll send you a quote, £20 if you don't want the repair, if you don't pay either we'll get rid of the phone in 3 months...
So I don't wanna really send it off then find my parents get a £100 bill of which they don't know of :/
Most likely the lines are caused by a malfunctioning LCD. This can happen on its own or by physical abuse. Carrying your phone in your back pocket can cause this. If the phone looks great on the outside (no sign of big nicks from being dropped or warped from carrying it in your pocket) then HTC should find no reason to not fix it under warranty. Sometimes things go bad on their own.
Hey,
thanks everyone for your replies. I tried installing a different ROM (Cyan) on my DHD and it still seems to have the same issue, tried changing the cpu and gpu voltages, playing with temperatures etc, but to no avail..
I guess the LCD did go wrong, so Im sending it to Vodafone (UK) for repair. The only thing is that they will probably send me a refurbished phone if they cant fix it which wouldnt really be my first choice, but oh well! Could be worse I guess...
Thanks again for all the feedback

WiFi acting up on my ALE-L21

For some reason the wifi on my phone is acting strangely, it just started doing so a few days ago but before that it was all fine. Basically what is happening is that my wifi will be really slow to the point of not connecting to websites (Connection timed out etc.) however the wifi starts to work if I turn it off and then back on, but then stops. I really don't want to be doing that every 5 seconds. It used to be fine and then suddenly it started being weird. So basically my phone is quite useless now since I use my phone for everything (I log into my google account with my phone, I need to use the steam app on my phone and other important stuff). The wifi on all my other devices is fine like usual. Bluetooth also says that the bluetooth address is unavailable but I don't use bluetooth so it doesn't affect me but I think it's also to do with my problem.
Currently using Sokkoban's Deodexed ROM.
What I've tried doing:
Removed PurePerformancesX.
Cleared Cache.
Reflashed the ROM.
Flashed to the Official Lollipop update.
Flashed to the Official Marshmallow update.
Rebooted my router.
Reset my router.
Anything else to do?

I've heard about this, it seems it's a common problem among P8 lite users.

It sounds like it could be a faulty wireless card in the phone or the drivers bugged out. Blimin' shame that your warranty is void cause I am pretty sure they would have to fix that for you.
I actually had a very similar thing happen to my old iPhone 4s, wireless just completely died in the end. No regrets about that though, it brought me to android.
Really though, sorry to see you are having trouble with this and I really hope someone here can help you more.

I decided to remove the back cover of my phone to see what the problem could be, but then my screwdriver was too big to open any further. I still don't know where the WiFi + BT antennas are. And since TalkTalk are cool, they said that my warranty lasts as long as I carry on paying my contracts, which is good. However since I'm just out of the 28 day return window I'll need to give them a call so that Carphone Warehouse can repair it for me for free.

SCREEN REPLACEMENT PROBLEM

hi there, I just replaced my screen for the umpteenth time but, on this occasion, it hasn't "taken". The old screen is totally obliterated, smashed display, but it still takes power and behaves as it should (lights up on disconnection of usb charger, for example). The new screen? Not so much. It does actually work, it shows the picture fine, but it only shows it for a fraction of a second then blinks off. When I press the power button again it does nothing, as it thinks I'm turning the phone off, then when I press it again the screen comes back on for a half a second or so and same issue. Have checked all connections, all fine, have swapped in the old screen to confirm it behaves as it should, all fine.
I'm wondering, could this be some kind of gpu/driver issue? Or has anyone experienced this before with a replacement screen and it's just a "dud"? Absolute downer as I've been waiting for it for a month or so and literally can't afford to buy another one at the moment, really bad year

I had a similar problem due to display incompatibility.
I have the phone marked FHD-D on the cable and the new display was FHD-A.
Or, the new display is not original...

Thanks for your reply and yeah, I'm figuring this is what is happening. However, the cable/screen are all one piece and were bought together, so is it possible they'd mismatch the cable to the screen themselves? idk, anyway, I've opened a dispute and have now been told that I'm stupid and that I have installed the screen incorrectly and not connected the battery (absolute gibberish).
I made a couple of videos for them, idk, have a look and see what you reckon but, indeed, to me this looks like straight up incompatibility as the screen isn't being driven properly by the phone (and, as you can see, the old busted screen behaves correctly)
Video of old/broken screen showing correct power response and on/off behaviour:
https://streamable.com/n16xo8
Here is the video of"new" screen which is clearly not correctly supported
https://streamable.com/28w8m2
Well hopefully I can get a refund for the part and get another. Can't even afford to order another at the moment until I get the refund :/ Lost my business last year due to covid and don't have access to state benefits or the like, so have just been trying to keep the head above water for the last year and a bit, so believe it or not something like this is a big expenditure for me these days :/

The original screen is "Boe" (see screenshot), this can be verified via the "Device Info HW" application.
Too bad the phone won't start and it can't be verified...

Yeah, it's a pain, I guess the display is just not going to work and I'll have to somehow get another - hopefully I can get the refund okay as those videos show it clearly doesn't work! The phone does actually start up, everything is going on fine aside from the screen. As I have to press on/off several times to get the screen to flicker, I don't have time to put in the unlock code and get into any menus, and then when it goes off I'm back to jockeying the button until it lights up again, at which point of course it's returning from a standby state so it's going back to the code input. BAH!
hello how are you 1 month ago I bought the second-hand mate 10 lite with the crashed but functional screen and I decided to buy a screen since the one I brought stopped working the touch screen everything was fine in the installation but the same thing happened to me as you understand normal but the screen does not work when the device is finished charging and putting the pattern turns on the screen and also that when I make a gesture it does not work I have to press a little hard and I realized that the screen came out a slight defect and I cannot request a refund since remove the security seals when installing it in your case if it came out with a major manufacturing defect
Note 2020 just look at the date of your post and still comment hehe greetings from Mexico
