CAUTION

[A320232]

I request users to please check the screens closely of their Xperia ZL. Disable the "auto-brightness", keep the brightness to maximum and set the screen time out a little higher say 5 minutes. My Software version is 4.2.2. The screen FLICKERS. I had my previous Xperia ZL exchanged because of this problem and the "new" phone has the same issue. I am currently having a miserable experience with Sony and their service centers here in India. My previous ZL had a motherboard problem and I am not totally sure if the "new" one is really new or the old wine in a new bottle. If things persist like this I'll probably head to the consumer court.

Any inputs will be greatly appreciated.

Then surely it's a case of me being conned.

No problem on mine either. Please do note that there have been some reports from Z/ZL users having screen flickering experience after upgrading to 4.2.2.

Hmmm the problem seems to come and go. But my previous ZL had a motherboard issue as confirmed by SONY. As I'm typing this message, there's no flickering at all. I am confused. I want to get things right within the warranty period.

Yes, it is very frustrating. Some just restart their phone and the problem is just gone. Some experience the problem again after a few days. And not many people have this problem. So, we can't tell right now if the problem comes from the new firmware or from the hardware itself.

When I keep brightness full n that brightness slider is on screen it flickers once while rotating the screen.. When I remove that brightness slider n go to main settings menu no flickering occurs also when auto rotate off no flicker...i thing but I never use full brightness n moreover it flickers just once before rotating so I guess nothing much to worry.

Thanks everyone..

Hmm btw another question, the replacement unit I got comes loaded with those wallpapers one usually sees in demo units. Here, the ones in the last few rows. Please check this link :

http://forum.xda-developers.com/showthread.php?t=2152482

And is it true that it's not possible to get a SIM running in demo units? I am able to make and receive calls but, for some reason I'm getting a feeling that the replacement I got is a demo unit. The IMEI number on the box and that of the phone are the same but the box does not contain the charger, earphones and the USB cable.

BTW, what I mean by flickering is CONTINUOUS faint flickering of the screen. On the entire screen. The screen shivers!

Yes only the phone was replaced by them. But, the flickering comes and goes. I am having a horrible time here. Is there any chance of a refund? Worst case, I will ask them to give me an XZ as I have lost all faith in ZL anymore.

Every xperia has a demo installed in the phone..it has a demo folder somewhere inside the internal memory which contains the video demo file I foud out when I was exploring the internal memory n there is some code to activate demo on the phone all phones so no need to worry abt that n regarding only getting phone...its policy that company will exchabge obly things that u have problems with...since you had problem in phone and not in accessories so they sent you only phone nothing much I myself got replacement for faulty led indicator n they replaced only phone...

I have done all possible things from my end. My first ZL had a motherboard problem and after much argument, I got the replacement which isn't any better. They initially wanted to replace the motherboard only but I rejected it. I had asked for a completely new phone.
I usually keep the display at "auto". But now, I have kept it at "max" to check if the flickering occurs. It comes and goes. I last saw the flickering today morning. I will ask for a refund since I cannot keep a faulty product. And, I agree with you about ZL>Z in many aspects. This phone fits my requirements perfectly but what I have been going through over the past few days...a real nightmare.

i understand your problem like you i am too a little touchy about my devices faults..then its better you directly demand talking to one of the executive manager. bt sad to say ,i dont think they will refund.and this time if they exchange ask a sealed box.

It's 100% related to the 4.2.2 update, so be comforted it's not in anyway hardware related. This was one of the primary reasons I downgraded back to 4.1.2.

The problem is temporarily solved with a fresh install of the 4.2.2 update and then randomly comes again. I do not know what to do. I am forced to run to the service centers time and again. Is there any way to downgrade to 4.1.2 without losing the warranty?

 

[spielnicht]

Yes, you can downgrade back to stock 4.1.2 firmware, many of us have done it (flickering was one of biggest reasons). It will keep your warranty 100% intact since the bootloader isn't touched. Remember, only unlocking your bootloader voids your warranty, and you're not doing that here. You're simply using a 3rd party tool (Flashtool) in place of Sony's PCC/SUS tool to flash a 100% stock Sony ROM.

Just follow these instructions I posted last week: http://forum.xda-developers.com/showthread.php?t=2342680
