[Q]Display flickering - Xperia Z Q&A, Help & Troubleshooting

Hi all,
Though i'm happy with my z i got a small problem.
The display is flickering constantly, i read in several Forums about this should be an Software issue with Sonys 4.2.2
So i went back to 4.1.2 but i still noticed a flickering on the display, and in any other Rom i tried.
Question is: hardware or software fault?

Wait until the New bugfixes are out it could be a bug within the kernel that Sony have finally found but I'm no expert I've just picked up info on here across multiple devices due to my love for New tech

Alnikkis kernel fixed the flickering for me.
So it should be fixed on new firmware hopefully permanently.

I did this to remove flickering.
1. Reseted the device.
2.Repair Installed the software Via SUS.
Fresh installed the apps after reset and the flickering was gone.
(FYI my device is Stock JB ROM 4.2.2 V .244)

Thanks but i managed to get the flickering away.
It seems like a kernel fault, and should be fixable.
I also contacted sony support and pm'ed mods becoz of this issue, hoping they will finally fix it..

Ahh~! I was really becoming to get annoyed by this and believed it's a software issue rather than hardware faulty, so I wanted to check if anyone else is experiencing this. I'm glad they're going to fix it.

friend
this is hardware issue with the pcb of xperia z and there is no pcb schematics available, so search for the hardware solution, may be it is a small capacitor on board.

Pinch and Zoom issue

It looks like Sony messed it up again after it was prevalent in arc. The below video shows how the pinch to zoom works jerky and doesn't work properly at times. To better illustrate,
* I have zoomed in using default Album app
* Used QuickPic as well
* Zoomed in a website in Chrome
In all cases, the zoom doesn't work. It simply doesn't record my gestures properly. Many of the users have reported in the issue, I'm hoping myself that it's a firmware issue. But as time passes, it makes me think that my panel is faulty as well. Please report or suggest guys. If you haven't tried this yet, then please do across all apps which this zooming feature.
Steps taken:
* Ran Xperia Diagnostics app.
* Full repair in PCC and also in FT as well.
Note: The video is hefty at 78 megs, sorry in order to show you how clearly it was misbehaving, I couldn't compromise on quality. Please do watch.
Box link: https://app.box.com/s/mas3tj8gvaqctn19dq1n
Update: It's a hardware issue. Gave my device for replacement today.
I to have the problem..and other peoples i asked on xda said that its working perfectly so dnt know is it software based or hardware based..waitng for the software updates other wise will go to the service centre and get it replaced

I genuinely don't have this problem. My zooming is smooth with no jumps.

Hmm have to say not come across this issue, pinching and zooming is fine for me. Things that you can try: Update the phone to the latest firmware to rule that out, if you still have an issue then it is a hardware fault with your panel, i really do hate how people are so quick to bash Sony. Things like this happen, hardware faults do occur from time to time, get a replacement if that is the case, warranty should cover it.

They will and they should. I was told that if Z1 was bought a week back or within a week, they will replace the entire kit (box). As mine's 2 weeks old, I'll get the device only it seems. They've quoted me a max of 3-5 days. They told me that I'll also get a backup phone after 2 days.

Do you know what? When I gave the device, the issues I mentioned were the zoom and yellow hue issue. The rep didn't agree with the hue issue although he agreed with the zoom issue. But after he started using the device, two additional issues were found. SoD and random reboot. My Z1 started rebooting randomly.Phew, I gave it at last. The problem sheet of my Z1 has four issues in total now.
Haha..actually i know how to enable the sod issue just untick the optimize backlight option and restart the phone thats all the phone will be screwed till u tick the optimize backlight again anr reboot

Same, same same!!! I had the same issue too after disabling it. Don't worry. A few reboots should do. Also you can leave as it is for some time then try again. If not, then start the device - Power off using the red colored switch present in the SIM card slot. Reboot again.

Then they decide to suddenly remove it then shortly after replace it and we don't actually get the update until late July thus far I still haven't received 295 and February's almost over.

I also had that Customization number but couldn't wait so I flashed rooted .295. Didn't regret.
So maybe that's why some people didn't get the update? They've stopped the update? Is it possible?

Slight Off Topic
how come Xperia TX never showed up in PTCRB certification? until now theres no 9.2.A.0.295. but it is released already.
On Topic
This update should fix all kinds of bugs that are obviously present in 9.2.A.0.295
-Volume(not showing and not changing the volume)
-Movies App(Blue Flickering Bug, when Show Recent video is turned on)
-SD Card(Sometimes Walkman and Movies App, can't read any files on SD card)
-100% Charge(Full Charge bug)
-and all the bugs we have or not have encountered, and hopefully they will further improve the software.
Is anyone not bothered by the stupidest bug I have seen in an Android release (No offence to Sony, but its actually pretty stupid)? The installation progress bar which is way out of place. How could they not see or fix this? I'm sure its a simple fix.
Little things like this do bother me.

I know what you're feeling, but this happens because they were focused on fixing worse bugs (the charging one that reboots the system, is incredible and not fixed yet)

Yeah I know! But what I meant was this is a simple enough fix
But yeah... there are bigger issues that actually affect the functionality of the phone.
Looks like 9.2.a.1.199 has also been certified for TL...

[Q] Sound Bug After KitKat Update

Hello, i recently updated my Sony Xperia Z1 Model No: C6902 with the latest kitkat update but after the update their is disturbances heard in the message notification tone....what shall i do? is there a problem with the update itself?
Maybe, to early to say if it is a bug, some users have to report it as well too. Try Factory Reset first, it will wipe your data but it will clean up after update.

Do you have any mods installed that may have restored with titanium when you reinstalled the rom?
Could be that something is not playing nice with the new base.
Attempt a clean install with no restores and test the audio, then restore and if it comes back after the restore you'll know if it's a rogue app / mod or not.

Shahzaib.khan I don't believe your referencing the same bug we are discussing. If I'm not mistaken your discussing the sound through the internal earpiece instead of the loudspeaker. We are referring to a notification tone which skips when being played during an actual notification

Only a reboot fixes the problem. But after after a few hours it's back again :crying:
Guys i guess i was right at the first place
I comeback to 4.4 from the start
I flashed xperia ultra firmware which is modified by nut then i put 156 of xperia z1 then i root it and flash recovery on it and then formated every thing except external card, i formated internal memory also. And yes till now received 5 calls there is no problem...
Try it every one

Hi,
Is this problem solved now for you after the update to .757?
It hasn't for me. I still get the annoying broken/disturbed notification tone many times even after a clean install of the FW .757.
I am on stock ROM, non rooted. I really do want to know which app is playing rogue, if it is an app. I thought after the few updates to the walkman app, it may solve the issue, but it didn't.

[Q] Screen not turning on sometimes?

Hi everyone..
I noticed that my Xperia V occasionally does not turn of the screen when I press the power button. Even if I do so repeatedly..
Only solution is either to wait some minutes or to remove the battery.
By the way, if the error appears while charging and I plug out the usb cable, the screen turns on and everything works fine.
Running stock 4.3, but I doubt that this problem is related to that, as I've already been running 4.3 for several weeks before the problem appeared the first time..
Any help or hints are greatly appreciated.. Thanks in advance!

By the way, these issues also started for me some weeks after upgrading to .199.... Hm.
