[Q] Display bad pixels? - Xperia Z Q&A, Help & Troubleshooting

Hello i have bought a used xperia Z. I noticed it has about 5 white stains on the display. You can only see the stains on light color (white,yellow,green etc.) Black color look normal. Are the white stains (dots ) on the display a big problem? It look a little bit like moisturized.Did anyone have similar problem? i will try to throw on photos later.Anyone similiar with this problem? Tried using dead pixel fix form play stor, it doesnt help anything.

they are stuck pixel sometimes working and sometimes ... and won't destroy other pixels (it s usual issue on lcd displays)
But if they are not annoying for ur eyes leave them cause fast flashing the screen and such solutions don't solve anything.
but sony will replace if it has warranty
:good:

it s used phone and i don't know what did happened for it
maybe last user modified it or was working not properly
so best choice is to take it to official service
however u can first use PC Companion app to repair firmware if these problems be in software this can solve all of them
:good:
if it was helpful hit thanks

[Q] After JB update,I see about 4 very small bright pixel on the screen.

Though these 4 pixel dot only visible when brightness is at 60% and specially visible when background color is black. Can Dead Pixel Fixer app fix it? or I have to do something else.

see if it's a hardware problem first by taking a screenshot and seeing if you can see the pixels in the screenshot. If you can, it's a hardware problem, if not, then I guess you can solve it somehow, either with that app you mentioned or flashing a new firmware

I took screen shot, there was no problem in that picture. I tested many things, and the result is - the dots are only visible in Black background when brightness is above 50%. Otherwise its not visible at all. Phew....... That's a relief :victory:

OOHH woops I meant if there are dots in the screenshot, it's a software problem, and if there aren't any, it's a hardware problem

My history:
Buy Xperia V with .489 no have stuck pixel (60%, 80, 100%)
upgrade to .140 increase brightness at 60% and now have one stuck pixel (green). :S software problem
im using .140 deodex and DoomKernel or vKernel
note im not sure but I thought I saw it before unlocking the kernel and put vKernel/DooMLoRD kernel did not have this problem.

Half-responding screen

Left part of my screen doesn't respond to clicks! (Screenshot, issue area is on red)
Issue persists between roms (Tried GDX and stock).
A few minutes ago I realized that left side of my screen has some bright, so I compared right side (Photo) with left side (Photo).
No, that white bright is not wallpaper reflection. It's white on color wallpapers too and even on completely black wallpapers.
Any idea?
First thing that comes to my head - did you drop anything on it?
Secondly how long has this issue persisted?

1.- if you mean hit: all hits it had (almost none) were from about 15cm high.. nothing to worry about....
if you mean liquid: no
2.- about a year, because I thought it was a rom issue and I never used any other....
it has 1 year and 6or7 months
thanks for replying! i thought nobody was going to haha!
It's definitely a faulty screen or digitizer. If the issue persists across all ROMs and kernels (you don't have to check each one of them), then you should get your screen or digitizer (can't really put my finger on which is causing this) replaced.
F***.. So, there is no doubt its a hardware issue? Then i'll have to live with it -.-

[Q] Touch screen - horizontal position

I have a problem. When the phone is located for example on a table. This touch screen responds very hard (when it is in the horizontal position). when phonei is in the a vertical position, the screen works very well.
I have firmware 12.0.A.1.257.
yes sometimes
when i connect to my laptop it used normal
but when i connect to my PC i cant use my phone
maybe erro from hardware but i think u should tick off gloves mode in setting

i bought a Xperia Tipo for my baby brother last week and it has touch sensitive issues just like SP when it placed horizontal ( i watched the Utube Videos and it looks exact the Same) but i found a little Mod App called (Touch Calibrate) i want you test it for me and say that if that worked for you or not!

Did You Check Unknowns Resources in Settings?!
it should WORK!
if that didn't work search TOUCH CALIBRATION in Play Store and let me know
Touch Irresponsive, Screen Freezes
Like a lot of users, I am also having problems with the xperia SP's touch screen. The touchscreen becomes randomly irresponsive. Sony acknowledges the problem and suggests:
"This have now been investigated and if you experience this problem I advice you to contact your local support team to have your phone calibrated at a repair center."
The problem is in live in Bangladesh and they do not have official Sony tech support centres. Does anyone know how to do the touch screen calibrations ? Any DIY solutions will be highly appreciated.
Cheers,

Sony Xperia Z1 problem with the Battery, Touchscreen and Overheating

Hello guys, how're you doing?
My Sony Xperia z1 started making me mad due to several problems.
PS: I'm running android 5.1.
1- Erratic touchscreen:
the touchscreen sometimes starts moving things (open app or notification bar etc...) without touching it
2- Battery
sometimes the battery drop by 10% or 15% randomly
3- Overheating:
my phone became hot after 2 minutes or using the camera!
so, I'm wondering if someone could help me fix one of those problems
sorry for my bad english
Thank in advance
ok, the camera overheating is normal if you're using it for long time, the battery may be for time of use this phone is 4 years old and battery begin to fail try some app to calibrate it if doesn't work replace it and screen touch have you change the screen? if change try to put a black wallpaper and test if the problem persist when you go to home( in developer options check the "show inputs" option and check), and try a stock rom to verify if problems remains.

thank you for the reply bro!
1- The battery is JUST 2 years old!
2- My friend's Z1 start overheating after 10 minutes of using the camera, which is soo good. My phone is overheating after 2 minutes!
3 I'm using an original Rom, I'm not familiar with CFW on Sony! I tried the developpers option and found some problems in the corners of the screen and the phone ramdomly rebooted while I was testing it.
try to flash and do a full wipe then test it again if keeps the same it's probably a hardware problem, the touch can be minimize with screen protector but the battery an camera it's hard to manage.
sorry for my bad English it's not my native language

Allright bro, I'll give it a try. Actually, am not using a screen protector because I'm looking to fix this problem before buying a new screen protector.
I'm having the same problem with my touchscreen, I can't use the phone for more than 5 minutes without having the need to turn it off and on again to go back to normal. This is making me very mad that I'm considering to change my phone to any deep **** cheap phone that has a good screen that I can use normally..
I don't know if it's a software related or hardware, I flashed stock frimware many times and nothing changed, I recently had an urge idea to remove the stock screen protector (that has sony logo) hoping that the problem will get solved, but I guess it won't..
If anyone has an idea to solve this I and OP would be very grateful..
the screen touch is a hardware problem try to lower screen brightness and put a dark screensaver, it's somehow related with the contrast of the screen but not sure how to solve it completely the previously and a screen protector only make it usable but don't solve completely the issue.
sorry but that's all I know

Screen flickering

Hi guys,
My phone's screen is very mildly flickering . Very mild . It's like light blink. It happens mostly with white screen background . It is quite a concern cos am worried this might become worse as time goes by . Anyone knows what's causing this and a possible fix ? Btw this happens in safe mode too
Pls someone reply
It sounds like a hardware issue, I would take it to a Samsung Store and see what they can do about it.
Mine just started doing it, but my note 8 is already gonna be shipped to them to fix the burn-in issue im having. Hopefully it will fix the flickering aswell.

Hmm I too feel the same but it is only very mild . Only when observed very closely the flickering is visible that too happens only in white screen

Doesn't look like a burn in issue for me . Looks more like something wrong with ambient light sensor.
