[Q] Black Dots on Xperia Z Screen When taking Pictures - Xperia Z Q&A, Help & Troubleshooting

Hi There,
I really need some answers. Two days ago i noticed some black dots on the screen when opening my camera. I taught my lens was dirty, so i cleaned it but still the black dots remain on my screen. i switched it to the front camera but that one didn't had black dots. I restarted the phone but still they remain. I took some pictures and went on my laptop to checked them, and they were on the pictures (the black dots) I searched online and i found some forums were people said that it is a hardware issue. But now. Today i checked my Camera again. And the black dots just disappeared. I saw nothing. So now my question is. Does anyone knows what the problem can be? Is it really a hardware problem or is it just a bug. Oh yes i have The latest OS on my Xperia Z.
Please i need some answers :/ i'm so stressed out

Anyways you can read my issue below ... ... ...
I purchased Xperia Z on March and I had issues with dead pixels in my camera which i noticed in the month of may. Because of my busy schedule i could not visit the service centre and i was not too worried about the issue as the handset is under indian warranty.
Atlast after adjusting my duty shifts I went to the service centre and enquired about the issue and and they said they would replace the handset and it would take 7 days for them to replace it, so gave the phone to the service centre on 17/08/2013. Today i got a call from Sony Service saying that the handset is ready and it is a Brand New Fresh Replacement in a Sealed Box (Old Xperia Z was Batch 13W08 and Replacement One is Batch13W18). It just took 3 working days to get a replacement, really fast.
NB: You can track the repair status (India) online at http://sonymobile.servicetrack.in/

Screen problem or graphics card? Broken Kaiser?

About 10 mins ago I was in the middle of typing out a text message then the screen went like this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

It's very white, but you can make out some text and icons, the touch screen still works.
I'm using the original O2 ROM on my O2 XDA Stellar, and have never flashed the ROM or HardSPL (Yet!).
i tried booting into the bootloader but the screen is still like that, so I presume this is not a software issue.
Any suggestions before I call O2 for a replacement?
EDIT: I must point out that the screen is still at it's proper brightness, it is just mostly white! Kind of inverted infact.
Hi,
I've the same problem!!!!!!

No way! What device is yours, the Stellar?
Just tried a hard reset with no joy.
About to call O2. Have you done anything bout it yet?
My device is an Italian HTC TyTN II.
I also tried with an Hard Reset, but nothing.......
I sent it to service center.......
Well I've called up O2, who were very good. Because I have had the phone for less than 28 days, they are sending me out a brand new one immediately, and I just swap the broken one with the new one at the door when it arrives!
Same thing exactly happened to me tonight. I guess it's a hardware problem. I'll be calling AT&T tomorrow.
Well I've received my replacement fine. O2 sent it straight out, next day delivery, swapped it at the door.
One interesting thing I have discovered is that the keyboard and external side keys are much better than in my old one. I had initially complained about them,the keyboard was not very responsive, some keys hardly clicked and it was hard to tell if you had actually pressed them sometimes. The new one is almost perfect!
same here humm this is gonna suck now.. anyone know how to return att phone with out an account
Well, my phone started doing that same thing last night.
I bought my Tilt about six months ago and it has been the greatest phone I've ever had.
Last night after touching the Contacts icon at the bottom right corner of the screen the whole screen turned very white just like the photos posted on the first post of this thread. I can still read the text, but the screen is too bright even though it is set to the lower brightness level. If I increase the brightness it gets almost unreadable.
I slided out and tilted the front and it came back to normal. It hapenned again and I did some very small hits with the tip of my finger and it came back to normal. It happened like 5 more times and got fixed back with some small hits with the fingers. However, after the sixth time it has not come back to normal.
It seems to me like some bad or broken contact, specially because it seems to happen when I touch the bottom right corner. I don't think reloading any software will fix this.
Whatever the problem is I will have to solve it myself since I bought this phone over Ebay and mailed down to me to Costa Rica.
I'm planning on opening the front and examining the display today in the afternoon. If anyone has some tips to share with me on this particular problem or on how to open the thing I will really appreciate them.
I did open my Tilt today as well as another good working one from a friend of mine.
The display from the working Tilt works just fine in my phone while my display does the same too bright behaviour.
Looks like a defective display to me. I already ordered a replacement.

X1 optical joystick problem

Good day everyone
i'm using my X1 since about 2 weeks.
I recently did notice that after waking my phone up the "scrolling down action" is performed...so the optical joystick thinks i'm moving downwards but in fact i'm not even touching it...it not only happens after waking it up, but also when i want to scroll upwards it happens often that it's sliding downwards again when i release the touchy surface...
cleaning of the touchy surface didn't help...aswell as adjusting the sensitivity of the optical joystick...
does anyone else have that problem...or anyone out there having an idea how to fix?
mine dont have that problem at all and if hardreset dont change it i would
write it off as a hardware malfunction
Some solution?
The does same thing happen to me?
I had this problem before too. Somehow, while i was at school, i must have shaken it a lot or something, because i had P.E. that day. When i got home after i had p.e., the joystick scrolling problem stopped. I had the X1 in my pocket the whole day, so i guess when i was running in P.E., something must have shaken and the problem is now fixed.
This has happened to me only once, while browsing. It fixed itself after a soft reset. Very weird.
Solution!!!
Mine had a very similar problem. It was making calls alone once something just touched the joystick's surface. I took it to a repairing center (with a little hope once i read above comments). However they repair it, well, at least the joystick is working on its scroll funtion but when I press it nothing happends. They told me that it was repaired by just cleaningl, with paint thinner and a gum eraser, the part that is marked inside of the red circle in the image below.

Mine's got that problem too.. It was so annoying that I disabled the optical joystick thingy... Don't need it anyway
Im glad i dont use that optical thingy. Its annoying when you want to press center button on D-pad but then accidentally scrolls up or down.
Sorry for poping in this post again after er.. i think this is like a year old post. I just had this problem last month.. or maybe months. I been ignoring it for some time now but well it is getting annoying (It always make the speaker go louder for some odd reason by scrolling up or while searching for a contact it scrolls up). I have never used the d-pad and thought of disabling it but not sure how too.
No more warranty as I bought it for some time already (They said so), I send it back to the shop and they wanted to charge me MYR200 to change the ribbon. After thinking a while that d-pad only cost like $7.99USD which is MYR25.10 from cnn.cn website.
Do they mean the slider flex cable which cost MYR147.619 (After converted)?
Does that has any relation with my D-pad getting stuck at the up button?

[Q] wonky flash + non working ambient sensor after power button service

Hello,
Recently I sent my nexus one for a button replacement. I got the phone back with some strange symptoms:
- Flash light blink at random event (first boot, after I hang up a call, etc..) but cannot be controlled by software (torch and camera app in CM7, MIUI or the stock firmware). The camera however works fine.
- The ambient sensor is dead. It either reports a very high value (2600 or 5800) or a very low one (10) (these values were taken from the CM7 auto brightness adjustment settings)
- Mic from the headphone when I plug in does not work anymore (the mic works before and tested to be in working condition)
From some online research, it seems like a loose connector can cause the wonky flash light problem (report by fblodroid, he fixed it by plug the connector back)
http://www.google.com/support/forum/p/Google+Mobile/thread?tid=46ef1e3a49030ed9&hl=en
My question is: can the other two problems be related to this connectors as well? Or did I get a defective board?
I plan to fix it once the tools arrives (dealextreme takes forever!). Another option is to bring it back to the service center to get fixed (this will take a week, and who knows what kind of fees on top of that). I'd prefer to fix it if I can.
Anyone has some knowledge about this kind of issue? Any idea what do those connectors do?

Dude, if your N1 is on warranty I wouldn't even bother to think what is causing this problems Send it back. You'd have o wait some time but you will still have your warranty for the future, and if you disassemble it you will probably loose it (not mentioning that your problem could be unfixable!).
They screwed up and they should fix it for free. I hate when electronics come back in worse condition after repair than before...
Well, it's out of warranty. But I think I have 3 months part warranty from the last repair.
They didn't put any seal on the screws this time. Maybe you're right, it's smarter to just send it back to get everything resolved.
I'm just curious whether all the problem described above can be attributed to the board they replaced (or one or two loose connectors).

I didn't know about the warranty, BUT: They spoiled your phone while fixing button so as a consumer you have right to demand that they fix it free of charge! Maybe it's something like silicon defect or "cold solder" (don't now if it's correct name. Google-Translated it) on the main board. They should have tried it before sending it to you.
Wish your N1 will get better soon

Top White "Flat-tire" glitch after update (forced one)..

Hi you all!
Has the title says, sometimes a white glitch in the top appears, normally after a charge overnight just after I disconnect the device from charging. The problem in my urbane appeared after a forced update by adb sideload, don't know if it's due to that but I'm not sure until I hear other persons that made the same thing, adb sideload of course.
Anyway I'll probably gonna take it to warranty, cause I'm afraid it might be an hardware issue... :crying:
When I have some kind of an answer I'll give the feedback.
Already posted something similar in other thread ( " I've already done everything to the watch, unlocked bootloader, installed TWRP and also pushed by adb sideload the new version of Android wear, the bass version one (LCA44B) and all went fine.
Although I will going to take the Smartwatch to warranty, cause lately, not always, he's been doing a strange thing... After fully charged, the screen in top center, starts to blink (of White color), kind of a flat-tire inverted really strong like a flash! Obviously it's a glitch of some kind that affects the screen... Even with a reboot, he keeps doing it while booting... Lucky of me... Damned...")
The unique solution I've found was to switch of the device, not reboot, I must switch of the device or else it keeps doing it...
It only happened two times... But... Its f****d...
Edit. Posting some pics in a while...
Sorry by taking too long but here are the photos and video....
Still had the time to take it to the store were I bought it due to work shifts and free time to do so...

Yes, mine was very intermittent. It first happened after landing on a long flight... figured it was an air-pressure thing... it went away.
It was then intermittent / infrequent over the next month but last week it suddenly got a lot worse, and more frequent (i.e. all the time).
New video:
Contacted Amazon, and had a replacement delivered yesterday - so I've swapped it out for a new one - so far so good

Touch Screen issue after May Update!

Hey guys,
I am back to the real OG forums of Android after spending a few good years with iOS devices. Ngl, missed this place a lot!
So I have been using a Pixel 4a (5G) for 2-3 weeks now, and everything was perfect until the May security update 2 days ago. Although, previously, there were a couple of touch screen issues observed by many anyway, a friend too who uses the same phone, same variant g025-e and we used to observe extremely **** typing experience while charging our phones, until this update, literally destroyed the whole experience for me specifically, and not my friend.
This update was about 16.9 mb and on the night of 1st of May, I put my phone to update and slept, within hours it was released. The next morning my frustration begins. There is a part of my screen, specifically between the app dock and home screen separator that doesn't work anymore. There is absolutely no damage to the phone, neither have I dropped it or anything. The whole "asd" row on my qwerty keyboard barely works. Tapping the letters on that row a million times might register a touch magically, but you get my point, its just extremely frustrating.
Furious, I immediately took it to Pixel Community (Pixel Community Post here) and I haven't received a reply there yet. I took it to Reddit (Reddit post here), and there isn't any help either.
I have run a couple of tests on my phone testing my screen, and to my surprise multi-touch isn't working either (I can't zoom into photos, can't use maps or anything for that matter) and my phone only detects one finger. Attaching screenshots below where you can see touch break (there is no point of posting multi-touch test here, it can only show its detecting 1 finger, and that also breaks in the area shown below):

}
As last resort, I have also tried removing my screen protector, playing with the screen-protector mode in the display settings but in vain.
Now I am thinking something definitely went wrong while my phone installed the update, and thinking of a full fresh flash of the Software after unlocking the bootloader. Please suggest what to do. Hoping for positive replies. I am not doubting the hardware because my phone just stopped working right after the update, even though the new update suited my friend's phone just fine.

Oh damn I'm sorry its that much for you mate. Did it happen after the update or just randomly?
the day I updated the phone, the touch screen started to not answer again on the top and then the problem is repeated gradually on the rest of the screen. I just made a factory rest, the touch screen no longer works, I will change the screen .
