Exact touch screen issue as in Xperia Z1 - Xperia Z2 Q&A, Help & Troubleshooting

Hi guys!
I bought my Xperia Z2 8 days ago, and I have touch screen issue, as said in this topic:

When I'm typing it doesn't react for my taps, when I scroll down webpages it thinks I'm zooming it. When I turn off screen and turn it again- problem disappears, to be back in a few minutes. Anyone else has the same problem? Is hardware or software faulty? I think I have to give it back for warranty, but I'd like to avoid it... Of course I've reseted it (hard reset) a few times, even installed new software with "Update Service"- nothing helps.

How to test this?

You would see this- when you type something fast, phone is too slow for you- it doesn't recognize taps, touch screen blocks, etc. Sometimes top notification panel goes to half of the screen and stays in one place.

[Q] Xperia Ray - Black screen after stand by...

Hi, first sorry for my english, I hope that it will be clear enough to understand my problem...
My Xperia Ray, updated to ICS, display a black screen (with backlight) when waking up after a stand by. I have to wait for undertermined time to have something on the screen, sometimes I remove the battery and boot the phone to be able to use it.
I updated it to last 4.0.4 ICS thinking it will resolve the issue, but it has not.
I can still use the phone when connected to MyPhone Explorer with the phone keypad, while the mobile's screen is black the MPE windows shows me the "normal" mobile screen. Everythings else works normally.
I'm afraid to give it to customer service, it was a SFR branded phone and I flashed it with a generic firmware.
Locked bootloader, sfr gave me unlock code for sim cards, lost my root with last upadte too.
Any help ?
Did it also occur on Gingerbread firmware?
Didn't try with GB, it happened when on ICS .562, SEUS update to .431 didn't fix the problem.
I have the same problem with my Xperia Ray.
It already happened on GB and now also on ICS.
The screen stays black if you try to wake it up after standby (doesn't matter if power button or home button ).
This happens around 80% of the time.
The only things that help are: Waiting a few minutes, taking out the battery, or hitting the power button like crazy and eventually the screen will show up again after around 10 times on and off.
I brought my phone to the service center of the shop 3 times and every time they tell me they won't repair or switch it because the hardware looked fine in their opinion (they don't switch it on there, the one time I showed them the switched on phone with the error, they told me they could see the problem but as long as nothing inside is broken 'it's not their problem' . I told my lawyer and now he is trying to get me a replace phone.
The problem even comes right after you factory reset so I don't think it's an app.
It happens without the sd card in.
I had an different homescreen launcher installed around the time it first happened, but I removed it and it still happened and I factory reseted and it still happened. So I think it has nothing to do with that?
I tried software repair with the SE Update Service and it told me everything was alright.
Does someone around here have an idea what could be the cause?
I brought it to SFR customer service (here in france) 2 time, the 2 time they just downgrade it to GB, diagnostic was "update problem". They didn't take in consideration what I told them.
One of the shop employee told me that the third time normally they have to replace it by another one. If they don't want to change it I think I'll mess up their shop...
This even happens on Xperia Mini
when ever i try to wake it up by pressing Home button or Power button
it takes about 3-5 seconds to wakeup
it should be instant isn't it?
I also experienced 2 times that even pressing
all the buttons doesn't wakes up the screen
but only back light, then i have to restart the
phone by removing the battery.:crying:
Me too !
I have tha same problem !! I can't take it esay..It's bad thing in my Idea! very disgusting :crying:
I've got the same delays on my Lww, sometimes my phone doesn't wake up at all, and sometimes it takes several seconds. I haven't found any solution for it, but it seems to be a Sony-specific problem.
Sent from my Transformer Pad TF300T using xda app-developers app
I have also the same problem from some days
tried to reset all with flashtool with no luck
the problem is also during kernel loading,tried different kernel,logo and cw doesn't appear 90%times
if someone is able to read in logcat file I have attached one here
thanks for any help
me also
i also have the same problem with my xperia x10
bad news for all of us.....

I turned the sound for messages and phone calls back on. On 'silent' the phone just vibrated.
It hasnt fixed the problem of the black screen completely, but it is happening a lot less for me.
Finally I brought my Xperia Ray to the shop where I got it for the third time.
I bought it 159 Euros in december 2011 (plus Sony gave me 50E back) and they refunded 270 Euro in november 2012 !
Not exactly a refund because I had to choose another mobile, so I took the Xperia T which was 430euro, so I had to pay 160 E for the XT.
Good deal for replacement of a one year old mobile ! Only problem is that I can't unlock the BL.
It is a strange hardware problem since the screen can eventually be turned back on, so maybe it is something in the firmware that is screwed up and doesn't get completely fixed by SUS. If I were you guys I would try this fix: http://forum.xda-developers.com/showthread.php?t=1492805
It may not work, but it is better than throwing your Ray in the trash.
I have the same problem. My phone (xperia ray) after standby or after reboot has black screen with backlight. At first waiting for couple of seconds and trying to wakelock would solve the problem, after few weeks to wake up my phone I needed it to reboot (pulling out the battery). Now I need few reboots to start the device with screen on.
I found workarounds like Llama combined with Nightclock (both from Google Play) for the screen never goes off, but this eats battery and also sometimes the screen would go off. I don't believe its a hardware problem because with this workaround the phone is usable few days (until Llama delay the "events").
Found a way to make a logcat from starting the device. Two are for unsuccessful startups (black screen with backlight) and one for successful (screen on).
I think the problem is in the kernel for not loading drivers, but someone who knows to read logcat will tell us/me for sure. I can't flash new kernel because the phone is with Bootloader locked (Bootloader unlock allowed: NO).
Kernel version is 2.6.32.9-perf
Stock Rom 4.1.B.0.587
rooted
PS. Sorry for my english its not my native language.
Just to add one or two more informations: even with black screen and backlight the phone is usable, like I can answer on calls, it vibrates when I slide to unlock... I also thought the problem is in proximity sensor, but if it was that case the touchscreen would be locked.
If you fully discharge the battery and after switch on,it start normally?

[Q] s3 Fails Dimming test after toilet drop

Hi folks, Haven't been here since my HTC tilt days. Wife dropped s3 in toilet and didn't take out battery right away. I took it apart about 10 hours later. Started with screen flicker. Dried it again over night and used hair dryer. I've used the on board diagnostic and all works fine except the dimmer test. Colors come up fine but when I tap to dim it dims and starts to flicker, goes black, flickers back, sometimes stays black or reboots. I've done a factory reset. I haven't seen any general screen flicker since. When it goes into sleep/screen saving mode it must go black for about 15 seconds before it is able to wake it up again.
Anyone know if this is motherboard, screen or software issue?
Thanks
Obviously it's a hardware issue dude. Send it to a repair shop because it may needs a new thing.

Thanks. figured I can bypass the problem if I don't let it dim. Set it to sleep only after 10 min. As long as you manually set it to sleep mode with the power button all seems good.

Okay dude.
So it seems that this bypass doesn't hold up. So I used my s3 screen on the wife's motherboard- no problems. Then I used her screen on my motherboard- no problems. Put hers all together - problems start again. Any ideas on that?
update
So to follow up on this. I had to use my wife's water exposed S3 motherboard on my S3. All worked well. I must assume that the wife's screen is bad. I also noticed that this phone drains the battery 2-3 x as fast as it normally would. Anyone have a screen problem do this or is this probable of a screen dysfunction.

[Q] Rolling screen, please help!

Hi all
Sorry for a newbie question.
I have a Sony Z Ultra which I really like, but recently the screen sometimes just starts rolling for no reason. I cannot read anything, and it often does not stop. I turn the screen off, then on, and it often doesn't show anything but then it does it is still rolling. I have to hard reset, and even then have to do that a few times before it starts up normally. It seems to be happening more frequently. Any ideas on what I can do?
Thanks so much
Craig

Rolling back? Screenshot

It is more like rolling upwards, like an old tv that is not tuned to the channel properly (I am showing my age here because I still remember that)
I cannot take a screenshot because everything on the screen rolls, so cannot access the screenshot function or anything else for that matter.
I have found that when it happens I bend the phone backwards a little and it stops. This makes me think that perhaps the case may be slightly bent from a drop or from having it in my pocket which is somehow causing the problem.
It is not doing it now; I hope it won't return

From what you describe it sounds like your flex cable is causing the issue.
If that's the case, I could be wrong you can take it apart or return it to Sony. I'd just buy a new one. Sounds like a flex cable issue to me
A final development in the story of my phone. The rolling came back, got worse, and then I had times where I would push the power button to light up the screen out of power-saving screen off mode, and nothing would happen. The back-light would light up, but just a blank, black screen...
I sent it to the repair center and the quote came back. It would need a whole new screen.
The cost was going to be pretty high, so I looked online and bought a whole new phone for only 60 cents more than the repair quote!
I just hope my new phone lasts longer than the old one

Ghost Touches on Sony Xperia Z2

I have a sony Xperia z2. Bought it a year ago, everything worked fine for 11 months. One day i was using my phone and suddenly the screen went haywire. On further inquiring i realized it suffers from ghost toughes. I enabled the show touches option to give me the exact idea where the ghost touches appear on screen. There's something strange about it, only 2 ghost touches appear on the top right side of the screen, BUT WHEN I SWITCH OFF MY SCREEN AND SWITCH IT BACK ON THE SCREEN BECOMES RESPONSIVE FOR 5-6 SECONDS. Then ghost touches appear again. I have TRIED everything, formated, restarted, changed screen guard, cleaned the screen, changed the charger, did a software repair procedure suggested by sony. I really really really need help, I'd really appreciate it if someone tells me how to fix this issu. Thank you.

Problem with touch screen or software bug?

I bought a Mate 20 Pro on preorder and noticed within a few days a seemingly non-responsive part of the screen that was an intermittent issue.
Basically every now and again (often enough it’s annoying but not every time) after I unlock the display I am unable to select any app icons in the lower half of the touchscreen. The top half is fine - the home buttons are fine but everywhere from the middle down is non responsive.
I assumed a hardware fault so amazon replaced it for me - and the new device is exactly the same!
Am I just super unlucky and have managed to get two faulty devices a month apart from Amazon or is something else causing the issue?
Thanks.
Think you've just been unlucky,nothing like that on mine
Fine here too. I assume you tested this as soon as you got the phone before installing any app / custom launcher?
Have you tried running smart diagnostic tests manual mode in hicare, there's a touchscreen display test.
Sent from my HUAWEI LYA-L09 using XDA Labs
I only noticed it in use after I used a custom launcher however I tried multiple launchers and saw the same behaviour.
I just did the HiCare test and it says normal. I did hard reset it the other day and it hasn’t happened since so I will see if anything else happens. I can’t say I am thrilled by the thought of another swap from amazon if it does happen. That’s super bad luck.
Hi how did it go after the hard reset?
I got the same issue myself but instead of being the lower half, my entire screen does not respond to touch. I've done a hard reset my self and i do run the stock launcher. Even though my screen still doesn't respond to touch now and then after unlocking the screen or receiving a phone call.
Touchscreen issue
Yup I get it annoyingly so as well! Often takes a "double tap". Pain in the ace!
