Touchscreen became crazy! - Sony Xperia ZL

Hi all!
After playing candy crush for 1/2 an hour (don't blame me ),my phone started to act strangely.
Very hard to unlock and seems like somebody remote touch everywhere on the screen...
Opened it,checked all cables and ribbons with no luck.
Even factory reset with flashtool do not work.
The problem is also in recovery,so I think it's hardware related.
Maybe i could buy a new digitizer but I dont want to spend 50 bucks,wait days to receive it (with no guaranty it will fix it).
I saw on youtube videos the same symptoms but no solution seems to fix this...
Any ideas?Thanks!

After a reboot,touchscreen si partially working in some places.
Phone is stable but is difficult to use.
I noticed that if i launch a multitouch test app,then it starts to ghost-touch everywhere...
Maybe i'll try to buy a digitizer and test it appart without unglue the screen.

Display problem - who can help

Hello everybody,
-3 weeks ago a had the first problem with my display: it was gone and when i tried to reset the screen was almost un-alignable. only after a lot of resets it worked again!
-now since yesterday my screen stopped working. All the other functions work like phone etc., but I only see the backlight of the screen and nothing else. I tried to reset, hard-reset and took the whole artemis apart. Only saw a little black spot on the displayconnector (can it overheat?!)
When trying to reset for a hundred times it worked three times! I was able to do a hard-reset with screen, but that's it.
-Another thing I notice is that when I try to charge my artemis it takes longer then normal for the orange charging-light to light-up. Also after 10-15 seconds it starts to blink in stead of constant-lighting-up.
I'm running Artemis touch 4.02 with battery status on 201 mhz (was running 247 mhz until hard reset yesterday). Radiorom: 3.21.90. Accesoires: sandisk 8gb sdhc.
Who can help??? Will fitting a new display do the job?
What a coincidence, my screen also stopped functioning yesterday for several hours and I was forced to use mouse mode, until it just started working again but needed to be aligned several times over 20mins of use.
Today, same problem. It comes and goes, needs constant realigning...
I'll be doing some surgery again when I get home tomorrow, dunno about black spots yet.
I've just replaced the digitizer on it and I suspect a contact has come loose on the back of the LCD (I hope!).
Anybody else have any ideas?
so you think it's a problem of the display, rather then the main board or something like that? because I don't get a view on the display at all, only backlight.
I'm doubting on buying a new screen for about 40 US dollar. Would be sore if that didn't solve the problem.
p.s. took the artemis apart again yesterday: saw a minor damage on the display's connector. If that can cause all this, then a new screen would be the solution I think. But how does the connector get damaged???
FIXED
bought new screen. problem fixed.
Did you buy just the digitizer or the whole screen?
I think by buying the cheapest digitizer I could find is where I went wrong, looks like I'm shopping for another one...

Strip of touchscren not working

Hi guys. I know many of you have had touchscreen problems and whatnot, i searched but it seems like this one is a bit different from usual. Yesterday the phone was totally fine; i woke up this morning and it had a lot of touchscreen problems: at first it registered touches without me doing anything, but after a couple of reboots it was just unresponsive. After another reboot and some messagging, the problem reduced to a strip on the screen simply not working. The strip is located exactly where the first notification on the status bar is (like when you receive a message and you click on that notification). I have the trueancestor stats bar buttons, so that zone is a tad more down than usual. Anyway, all I did yesterday was a quick game. I think it may be the flex cable not working because of the sliding, but it happened all of a sudden, not gradually. I must say that some weeks ago I had the same "registers touches by itself" issue when typing, but a simple reboot was enough. I tried doing factory reset, but nothing so far. Also I can't use pc companion to flash everything stock back (I unlocked bootloader months ago, even though I relocked it; I dunno if it's locked or not right now), and I can't seem to find a working flashtool download link -_-. I don't think that would help much, it probably is a hardware problem, but who knows. I'm on true ancestor 1.6 LE, stock kernel.
Any help would be great, as I fear the phone will get refused in assistance because of bootloader unlocking.
Did your phone had contact with water? When my screen had contact with water it registered touches randomly.
it didn't. it has a screen protector anyway; but that's not the problem for sure. it doesn't register randomly, simply a strip doesn't work now...
Hardware problem. Could be flex cable or digitizer.
Today there were two moments it began to work again, but a few minutes after each one the problem came back. Sigh...
Mine does that when the screen is moist or my hands are too oily. Are you sure you're working in a dry environment?
mhh... exactly that? I dunno, my hands are dry and i think the screen is too; it has a quite thick screen protector (the skinomi one), so even if it got moist that shouldn't be a problem, right? I'm now living in a different town and that may have changed something, but the problem didn't show up until now, and it was sudden.
Also, I noticed that using gamekeyboard on a certain profile I had buttons placed on the strip, and pressing hardware keys mapped to those buttons actually works. This restricts the problem just to the actual finger-touch-detecting mechanism. Does anyone know anything about this?
Edit: lol I heated the phone up a bit with a hair dryer. It works now. I hope it will last and I'll not have to do this again over and over

[Q] [Panic] Ditigitizer problem or Motherboard?

This is my problem:
In may, I bought a Xperia Play on second-hand web from a guy on my city. In time, the phone got wet by rain, and digitizer started to go sometimes crazy, specially texting. I could survive with it.
After 2 months, the Ribbon Flex crashed, it showed screen completely screwed up, like in TV, you know, that problem that happen to everyone after sometime . So I changed it.
The point its, when i changed it, my old Digitizer stopped working ok, it gave too much problems. For 2 minutes it worked normally, except the base of the screen (that zone of the screen didnt detect my fingers, dont know why). Then, it wouldnt work totally, till, in some moments I took the phone, it would work for only minutes. I controlled the phone with the pad, but when it went out of battery by accident, I wasnt able to unlock again, as I couldnt touch and unlock the Pin code so I can use the phone again with the pad.
So I buyed a new one, which of course, I dont know why it doesnt work too (this replacement comes from a trusted dealer from my uncle electronics shop, so for the moment, I dont think the new digitizer itself its the problem).
What the hell Im supossed to do man? Im starting to go panic, because I dont know if the Motherboard have something to do with all this, and that means Phone dead right? Ive seem a lot of posts, all I could google with the same problem, and there is a lot of different cases and solutions with the damned Xperia Play, all starting with the damn unresponsive digitizer.
I saw the guide above amd i already posted there, but I wanted to leave a thread. Please, I need your help if its posible. Thank you at least for reading this.
Try replacing your flex cable again. Something like this happened to be, but the digitizer was completely unresponsive. After I replaced it, it works fine.

I had the same problem before and I think it has come back to haunt me. Its not software, your digitizers seems to be faulty and it will only get worse. If you turn on the "show touches" options in the developers section (phone menu) you can see where your screen is affected. I tried everything and the only way I could resolve my issue was to replace the digitizer and LCD. Fortunately you can buy them at reasonable prices online and there quite easy to replace if you follow guides (Youtube have plenty) on how to do so. I replaced my own screen a couple of months ago and it worked perfectly until now. There seems to be something about the winter weather that destroys screen and i've seen people on other forums with different phones say similar.
had the same problem too

I had the same problem sometimes, but every time i had, it was the screen needing a clean. Sometimes a drop of water can simulate a touch or something else that adhere to the screen. So all i did to solve it was a clean.

Is the touchscreen of the 10 junk?

Well... Finally I can't hold back.
My phone is now like 2,5 years old, maybe a little bit younger.
A 3/4 year ago a had a problem with my display, it had a non responsive touchscreen on the upper part of the screen, about 1cm.
I send it to htc for warranty, it seemed to be replaced and I belive them, since a few scratches disappeared.
But now I face the same problem again!
And not the first time since the replacement.
Check my sig, there is a post about this problem and a "solution"
Electroshocking the display? Dumb, but it seemed to help.
Since I replaced my battery, I had no problems, but I used some cheap double sided adhesive tape and today I changed it to some t-7000 glue.
No problems at all....
A few minutes later a part of the screen is unresponsive again....
Well... I shock it again, restart the phone, bend it as little/much possible...
Working again.
Somewhere I have read, these problems are maybe pressure related, that's why I bend the phone a little (not much, not even visible)
Well just now, the time I wanted to sleep... I discovered this unresponsive screen part again!
I have no piezo handy, so I just try to press the screen and bend it a little....
Won't work....
Now, with a partial dead touchscreen and no solution that worked before...
The only thing that I can do... Write a rant about this...
Back to the title...
Is the touchscreen htc using for the 10 such a piece of crap? Or why is it failing like this?
It is not like I do brute force on my phone, the first time I experienced this problem, I had done nothing wrong... It just failed Suddenly...
After battery replacement... Okay, I was sad since I really tried to be as cautions as possible, but I was aware I can break my phone.
But it was running!
All these problems are occurring after some amount of time after I did anything hardware related to the phone!
Right now I just watched 2h on YouTube while charging....
And bang, Suddenly the touch is not working completely!
I have never heard of such a behavior before, nor I encountered similar problems with my other phones that I took apart.
I really love the 10... But why is it failing on me like this?
Especially after I got a fresh replacement display?
This is bull****, I really start to belive, the hardware component for the touchscreen of this phone is junk...
I really need to sleep now... Good night...

Is this a question.....post it in the Q&A section......
Edit :
I have mine 2.5 years now, no issues at all. There will always be people with problems and always people without. Consider it luck. That's it, not sure why there should be a whole thread dedicated to the obvious. So either get over it and buy a new phone or sort it with HTC......
Cheers.
Same. Have had my phone since launch and the only problems i had were with battery... and they were software issues so i was able to fix them... with the amount of times my phone has dropped i'm surprised I haven't faced more issues. For me the hardware on this phone is 10/10
Well, wasn't about to star a QA on this topic.
More like a discussion, which was right in the place I posted it. Even the title is a question, it wasn't obvious a normal question I really need a answer about.
@bilibox
I love the hardware too! The phone is awesome, else I wouldn't have changed the battery in the first place.
But even before touching the phone interiors, I had problems with the touchscreen.
I thought it may be a drop damage, since I had a few accidents with it.... But never something really bad, only dropping from like 20cm bed etc.
It survived every time!
My first faulty touchscreen was without any incident at all.
I belive to remember I just charged it over night, last drop was a few weeks ago...
Won't say it can't be the fall it has taken damage by...
But since I got a replacement screen and a few month without any incident the same problems starts to happen, but after changing the battery, I fist thought I damaged something.
But after opening it up again it worked without issue.
Right now I need the electro shock therapy like 3 times a day to have the part of the screen responsive for a while.
Even my phone is not in use, it will fail again....
This failure is soo random and fixable permanently (after I put it back together when it was working, fixing it with double sided tape, it worked) it still fails after gluing the screen in the backcover....
I have orders one last replacement part, the screen incl. Touch and stuff, to have this repaired....
If this won't work... Well... I was recommending htc to everyone who wanted a really good phone with awesome support in case of a damage.
I can't do that anymore, since I have these random problems with only the touch....
Yesterday it brake while watching a few videos on yt....
I really really hope... HOPE!... This is only a hardware issue...
With the new screen I even get some "original" adhesive to put it place... Maybe this will help....
The failure is obviously connected to pressure....
Since I was able to fix this problem by "bending" the phone. (bending... I was trying to bend it, I just pressed the screen and the edges... Really tough phone we have here)
To new readers:
No I don't want a answer on the title question, just tell me about your issues with the hardware of this phone.
The only thing i read all the time is "bending" and "dropping" a fall from 20 inches or even less distance would not hurt the device....yeah of course, from what planet do you come from.
This whole topic/discussion/Q&A is a absolute waste of time.
I'm very sorry for all the inconvenience you've been through with the device but complaining about it here is useless. And after 2.5 years of existence of this device there would be and endless list of topics here at xda about hardware failure if that would be significant. So i would recommend using the existing ones......if you can't find any that would confirm your bad luck.
Get over it.

Read well my friend...
After the warranty repair I haven't dropped the phone at any time.
And well... Instead of nearly 2 years with dropping, the new screen only survived a few month (5-6) without dropping.
The only thing I have done was replacing the battery.
And my repair was easy as f., since the replacement adhesive of the last repair was crap and wasn't really sticky at all.
There was no bending at all while the repair.
The bending was a way to fix the unresponsive parts of the screen as a temporary solution.
I bet, if I pry the screen out again, the touch will work again without problems...
Even if I need more force since my last repair, since I have properly glued the screen in place.
It is not like I don't know what I am doing... Tbh, I have no idea why the shocks work as a temp solution...
But for the rest, I am more in the electronics as in Android itself.
And if the screen fails at these random reasons, there has to be a malfunction with the way of picking up the signal from the touchscreen layer of the screen...
By using deforming force this problem gets better or worse it seems this connection seems way to fragile... I will look into this once my replacement arrives.
