Screen flickering using any custom kernel - Sony Xperia XZ Premium Questions & Answers

I got wierd flickering issue only on custom kernel though.
One moment, is when after a while in album app lower half of screen goes like broken matrix, pink lines and etc.
It can be fixed with a developer option "disable HW overlays".
Another moment is right side of nav bar is flashing on the top of the screen. Developer option doesn't make any difference anymore, only reboot helps.
Anyone has the same issue?
Guess that I will have to live without DT2W

Cingular 2125. Camera problem - gone black.

Hello,
I had some problems with the camera button on my cingular 2125 but I managed to fix it just by cleaning it with wd40. Unfortunately a couple of days after the issue with the button was fixed I notice that I was not getting any image from the camera sensor - just black screen.
The same time I was playing with the rom updates and now I am not sure if that might be a hardware or software issue. Currently I am on WM6 perfect english v6 and it works perfect except the fact that I am not getting any image form the camera sensor.
When I turn the camera app on it shows the loading icon for a split of a second as usual but then no image but a black screen. I can actually see the camera image area boundary because if has a different shade of black that the background black but thats it. When I turn the COOL EFFECT picture actually goes blue. Playing with brightness and other settings does not help.
Anyone can tell if it is most likely a fried sensor issue or some driver malfunction.
I think its a driver issue.
I've had the same issue with my phone. If I click on the menu and choose the Reset Brightness option the camera goes back to normal, but anytime I try adjust the brighness settings it goes to black and I have to reset the brightness again. Not sure what the problem is.
I tried with every possible setting in the camera app menu but nothing works. Also when making a video it records the sound but not the image.
I guess since there is not that many people with a similar problem I assume a fried camera sensor or some other hardware issue. I am trying to get a new camera on ebay but no luck yet.
Does anyone know if the camera for 2125/spv c600 can be taken from some other model.
The one from the magician looks very similar except the shorter data tape:

Screen Flicker/Static - faint wavy lines on lighter colored screens

Hi all
Recently started having this issue with my screen - haven't dropped it or anything either. On lighter colored backgrounds there are faint to pretty moderate horizontal lines flickering on the screen. The lines aren't colored or in one specific spot on the screen. It's hard to explain but it is similar to older projection tvs where there are those faint lines(static like) in the background.
I took a screenshot but it doesn't show the lines. I had been using Android Revolution HD 6.1 (great rom btw!!) and I've tried other roms since this began happening (thinking it was the rom) but to no avail. I'm currently running CM7.1.
Things I've tried:
changing roms
turning screen brightness up
turning on automatic brightness
turning down/off various animation settings
turning on light sensor filter in cm7 settings (helps a little)
If anyone can help it'd be greatly appreciated! Thanks for reading!
I would try unrooting, installing ruu from HTC website and see if problem is still there. If it is then you will be back to stock and can claim your warranty. If problem is gone then just reroot. This is a problem I have not read anywhere though so it is probably a hardware malfunction and would need to be warrantied.
Not a bad idea! I'll give it a shot and share the results once complete.
Installed stock RUU - screen lines still present so probably a screen hardware issue. Going to take it into the store tomorrow and see what they can do

[Q] Pixels Issue

Is anyone having display issues with the bottom 3 pixel rows?
It's not entirely annoying.
The whole display is shifted up 3 pixels. (not the physical display)
The 3 rows of pixels on the bottom stretch out the image.
You can see what I mean if you use the ChargerBar application.
By sending the bar to the bottom 1px in height, the bar is stretched out by 3px.
Then send the bar up to the top and it disappears.
You would have to increase the height of the bar by 3px.
I want to show a video. But I don't have a camera...
Here's a video of the issue.

I see it too... running cm7. Something needs to be done to the display, just change the number a little. If linuxbozo was here he could easily but i have no idea how sorry. Just try to ignore it, thats what i do. It is hardly noticible.
I see it on mine running emancipation....
Sent from my SAMSUNG-SGH-I997 using XDA
Its normal, noticed it as well.
I think its two pixels, not 3
What's strange is that when I reboot the device it's normal, the way it should look on the bottom. Once I turn off the screen for the first time and then turn it back on, this issue happens, and it stays until the device is rebooted again.

[Q] Flickering noticed on gray backgrounds? After ICS update

Hi,
I seem to have noticed flickering on the screen specially on gray-ish backgrounds. I can see lines moving up in gray backgrounds as in the settings page.
As far as I can tell it was not present while I had HC since I only noticed it after I updated to ICS. I have never rooted the tablet and it is running on stock ROM.
Does anyone else seem to have this issue? Or is it a hardware problem?
Thanks
I noticed some rare flickering (once or twice a day) after updating to ICS, stock and non-rooted. But I wouldn't say it's consistent, nor tie it to a specific colors or actions.
Iif you could post an exact method of how to reproduce the problem, I might get a better judgement.
I seem to notice it quite clearly when the background is of a dark gray shade (like the one found in the settings page) in a low light room.
I just opened up SketchBook and painted the screen with dark gray (R66 B66 G66) and noticed the same flickering implying that it is not app dependent.
I've tried two dark gray fullscreen images, with auto brightness on and off, yet no flickering occurred.
Attached backgrounds for reference.
Yep i've noticed too... meaning that my TF101 is having the same issue :/
Nevertheless, I believe it is a software issue, probably related to ICS hardware acceleration thingy.

[Q] Pixelated flashing lines on display screen

I've been having screen/display issues (not the yellow hue and separate of the touch screen sensitivity problems). Every now and again, I get flashing, pixilated horizontal lines. I don't see any dead pixels and when it's not blipping the screen seems to display flawlessly, so I'm not sure if it's a software issue or if the hardware is failing. Also it's not isolated to one particular area, it jumps around. Anyone have this problem? Any fixes? I haven't been able to find anything on it. PLEASE HELP. Below is a video of the problem.

Are you completely stock? Any custom kernel? Any rom?
Usually it's a kernel issue - tearing, but it's only present on custom kernels (never came across on the stock cm11 kernel). You might wanna try a different kernel though, if you're comfortable with that.
I have the same issue on my stock rom with stock kernel. the only thing i have changed was the developer options. i changed the screen animation time.

Was it working before those changes?

Perhaps this might help?

I had exact same issue during recording a video yesterday night !! I am latest mahdi and latest franco...
Funny thing is it went away once i exited the camera... what rom and kernel are u using ?
I've been having the same issue too. I don't have a solution for you, though. I haven't been able to find much about it.
Same issue here, stock all the way, only been since latest update. The update didn't flash properly, it gave an error stating it couldn't be located but i went through the files and it was there and then upgraded OK
I had the same problem. Selecting "Force GPU Rendering" in developer options cured it.
i have stock everything. i'm not rooted.
a reboot fixes the problem temporarily. shoot, all the issues i've ran into with this phone thus far (like the GPS not locking on) is fixed by a reboot. i know a reboot is good to do every now-and-again regardless, but having to do it constantly to fix issues is the sign of a failing device and is very annoying; it shouldn't be something you have to do with a brand new device.
i am facing this too randomly. Am on rooted 38R with Franco kernel. Rebooting is a temp cure but it will frustrating to keep doing it.
This happened to me after getting 38R. Fortunately it hasn't been back since a hard reboot. It would show up on Youtube & when dragging down the notifications area.
I had this today on PAC ROM. When I unlock phone and lock ring animation dots flash up made lines come across screen not sure what it was or why. Just rebooted phone. Back to normal. But trying out vanir later tonight try something abit different.
Also experiencing this here.
Stock ROM, clean 38R install.
Stock kernel.
Rooted, with a few xposed modules.
Started a day or two ago. Haven't found a way to recreate it. When it does happen, a reboot remedies it, but only temporarily.
I will attempt to screenrec it the next time.
I find it interesting that I only see mentions of this starting recently.
Same problem for me since the last update. Restarting the Phone solves the problem for some times. Maybe a driver issue?
Glad to see that it is not a hardware issue.
Same here
Same here, mahdi-2.8-bacon-20141001 ROM, enabled "Force GPU rendering" in Developer options, let's see if this comes back!
I have the same problem on latest cm nightly with stock kernel. And dev options works sometimes but it resets on reboot and my phone reboots randomly all the time. I'm starting to hate this device

I also have the same issue on Stock 38R update + franco kernel r27
It happens after the latest kernel update, before I never had this lines.
Lucky for me I don't have any reboots now but I fear that will come to pass as well.
Got the same problem with Mahdi Rom 2.8 - 20141016
Will be solved in Franco Kernel r28,he just confirmed this on his kernel thread.
Sent from my OnePlus One using XDA Free mobile app
same issue here. i have to reboot. its happened on stock and AK kernel. will try enabling force gpu rendering and see if it comes back
