C68: Black screen / no wake up from sleep mode
Background
We have seen some examples where Xperia Z Ultra / C68 doesn't wake up from sleep mode and the screen remains black.
There is also another case where the screen is slightly yellowish.
Solution
Both these issue are solved by upgrading the SW.
Make sure the SW version is 14.1.B.0.475 or later.

Yeah, that's called "SOD" (sleep of death), and it's no longer a problem for 99.9% of the people who are on firmware 257

I had SOD the other day running 257 It's only happened once in the two weeks I've owned the device though, hopefully a one off.
What does this actually mean? That it simply wont start again unless you restart it?

does this happen to you?
i was playing on my tablet then the screen turn soooo dark
like as if the bright setting is turn all the way down.
i can hardly see to operate, i press the power button then again to login.
but when i check the setting it appear untouch
even after turning off auto brightness.
Mine kinda does this... mine just goes super dark, but i usually just touch the screen or the power button and it brightens back up, just like a laptop getting ready to go into sleep or hibernate mode.
It happens again after I set timeout tok 30 m3inutes
It could be bad lcd, I could not see a thing.
That would suck if it is a bad LCD, but at least it would be under warranty!
This happened to me, I think it is because I had brightness at maximum... I turned the brightness slightly down and it has happened again. But maybe that's just me?

It has a light sensor and auto-adjust capability. I've notice as I move around with mine or change how room light hits it will darken or brighten. Doesn't bother me enough to go looking for some settings to disable it, but there should be some there.
I have the same problem too... everytime I turn off the screen using the power button then turn on again the screen turn very dark when the setting is set to auto brightness... it is very annoying while doing something on the S and went away from a while then come back to use it the brightness is totally so dim...
I'm sorry to say but you guys have a defective unit. Just switch it in right away.
turn off auto brightness.
I contact newegg yesterday but no reply yet.
edit: i call them via phone got my shipping label.
Turning off auto brightness doesnt help, but tuning down the brightness from max down slightly I havent had the issue.
If it happens again ill have to send this back, I feel bad loosing the official siony screen cover.
Byt loosing $30 is better than five ninty-nine us dollars.

The issue describedhappened to my first one which is why I know it. Just re turn it. Its not normal behavior.
It is the Android problem, not Sony. Unless you change OS....

my xperia x10 2.3.3 fw and before that doesn't bug me this much.
if all 3.2 fw tablet does it then i would blames on 3x
go ahead turn on your auto brightness and browse the net in a well lid room.
I have one that is doing the same thing. Also every now and then the screen shuts off and I cant get it to come back on for awhile unless I hold power for like 30 sec. Is this a defective tablet or honeycomb 3.2? Thanks!
I'm telling you guys, I sell the things andI KNOW the issue they are taking about. We played with the settings all day and it kept happening but the issue NEVER happened to any of the other units. It's most likely a defective unit because as I said, it only happened to the one unit.

i think they are not available in Europe yet - so you should be able to sell the cover easily if you ship internationally

Hey guys,
I have got my I9300 for 2 weeks and I just noticed that the screen is flickering when I am in a bright environment and have the screen brightness turned to 100%.
In fact it is more like a low frequency flickering with 50 Hz.
You do not notice this if the screen is on low brightness or in a dark environment.
Did someone experience the same? Is this because of pen tile? Because of some settings although I do not remember changing anything which could do this.
Btw. I am on stock ROM with the latest update (XXALF6) and Cf root + busybox without CWM.

Hello,
I have similar problem but in my case i can notice flickering (in bright sunlight) only when phone is in power saving mode.
Try to experiment with power saving mode and let my know about result.
Cheers
I have the same problem, 1 week old phone. In bright light there is flickering, but more like 30Hz.
Only visible by my eyes if the screen is white, (maps is good for this) other people seem to notice this easier than me.
Completely gone if power saver is turned off.
My question is, is this "normal" or should I return the phone and get a new one?
/JT
So I called Samsung support and they told me that it is "by design" as power saver mode halved the refresh rate to 30Hz.
Also checked my dad's phone, also sgs3, and I think it is less prominent on his phone, but it also there. Difficult call, but I think I will keep mine.
Can't see any flickering without the power saver mode, and to be honest will probably flash CM9/10 soon anyway.
I've had my XZU for a week now, everything has been working fine so far. Nonetheless I've noticed lately that when I turn it on I will see like a curtain or shade of colors from the top down up to half of the screen (it's like a flash, quickly disappearing), apart from that it will resume from sleep fine and no other issues, nonetheless is weird that this is happening now after a week of usage, I hope is not a symptom that something worse is about to happen. I have attached a Youtube link to a short video I just recorded.
NOTE: I do not think is a software problem because I booted the phone is "safe mode" and the exact same thing happened. It seems like a hardware issue that gets worse over time, because at the beginning happened once out of 4 times I turned it on, now is once every two times. I do not see a very good future with this phone

UPDATE 8/15: All my screen issues have been fully resolved with FW .475
So we have our own thread for the curtain now.
Sent from my C6802 using XDA Premium HD app
I think the issue is Power Management related, let me explain. If I turn on the device after being idle for a while (device is COLD) there will be no curtain issue, but if I turn it OFF and then ON right away (device is WARM) it seems the phone is entering a power save state and is not ready to be powered on again and that's when you get the curtain issue. The result seems to be very consistent with my explanation.
What I do not understand is that why this problem started happening after one week of usage, I thought it was application related but after my "safe boot" mode where no new applications are running only stock apps and I got the same result it can be application related. Also I thought that maybe the Stamina Mode had something to do with it, but it does not.
My last theory is that there is a piece of hardware that is getting degraded over time and when the phone is warm it will produce the curtain effect, if that's the case this is really bad, because the whole phone could stop working down the road. but it's just a theory.
Oh man
My experience with similar LCD issues has been around poor connection between the LCD screen and the motherboard. However, I'm by no means an expert on this.
I would definitely be claiming under the warranty for this.
I spoke with the vendor in Singapore and told me this is a known problem by Sony and they are working on a Firmware update. They suggested to keep the phone until the FW will be released in September and then decide if I will exchange it or keep it. The vendor also extended the Return/Exchange window until October so I will have enough time to test the phone after the FW update.
It's good to know that Sony has acknowledge the problem and is working on a solution.
Any chance Sony will do a firmware update to resolve this?
So it might be a firmware issue? I sure hope so

UPDATE 2
I think the problem is Power Management related, because if I leave the phone idle for 5min and then I turn it ON it will happen the issue you are seeing on the attached video. But if you turn it OFF and immediately turn it back ON again it will be fine. I think what is happening is that after 5min the phone will enter into DEEP POWER SAVE. The threshold to enter power save mode is around 15 seconds. I would say is something that should be able to be fixed with a Firmware update, but my only concern is why this problem did not happen during the first week, that behavior makes me think it's a Hardware problem that developed over the first week of usage, meaning a defective device.
NOTE: As you can see at the beginning of the video the phone has been Factory Reset, so there are no third party apps and anything wrong on the configuration.
http://youtu.be/vgnILc3ib8M
Mine did it the first day. I noticed it did it about 3 times that day. And I agree with you it might be the power save mode. Hopefully it gets resolved.

My Z Ultra does exactly the same thing but it does not worry me. Seems to be a software glitch that should be easily fixed.
Mine happens when i am taking calls and i turn the screen on or off. Other times it is random but normally when i have been using the device for a period and then turn the screen on and off quickly after using it.
But yeah, i do not think it is an issue to worry about. If it was serious, surely the screen would be having issues a lot more when it is on and not under these specific situations?

If it's a software problem how is it possible that during the first week the phone worked fine?, even after a factory reset the problem will still be there, that means (to me at least) that a hardware issue develop during use for the first week and now it cannot be recovered

Do a factory reset with full wipe!!!
For make sure you totally wiped that garbage bro
Does Omate Trusmart (1/8 1900) accelerometer turns off when screen is locked ? The listener doesn't work when screen is locked
I want to listen to the shake events without a partial wake lock on the screen( which drains the battery a lot). Any suggestions ?

Same for the GPS, so probably the same for all sensors.
I assume a new kernel is needed for this.
LOL. It barely works even with a wake lock. That's why not a single wake app works consistently on the 1/8. I would not expect to see such a minor issue fixed anytime soon seeing it's 6 months later and the firmware is still not secured.

I hope this will be solved one day, this is really restrictive as it stands...
I use Awesome On/Off to wake mine. It seems to work more often than not, but sometimes it doesn't and I can only assume that the TS has gone into a deeper sleep. But worth a try by anyone who feels a bit self conscious suddenly shaking their arm in public. Awesome just requires you to raise your arm to a normal watch-reading position.

I've discovered that the latest FW update (Onate_Truesmart_20140513.103530_v2.0) has introduce a new "Smart Mode" --> "Sport Mode", which basically turn off the back-light but keep the screen on hence, the sensors (Accelerometer, GPS, etc.) are kept alive.
I've been trying it for couple of days and it works great. It terms of battery drain, it is noticeable but remains reasonable. Anyway, if you are note recording any fitness activity, you can still change the mode after your workout.
Very tempted to get this phone now it under £400 only thing holding me back is the screen dimming bug when opening certain apps such as Facebook, chrome ect
It was the reason i sold my P10 because of this.
So has it been fixed or is it still present?

Still present in my mate 10
What is this bug about? I've noticed that the phone is at some brightness (using automatic light sensor) and out of nowhere, the screen is full bright and goes back to normal. Its like a blinking. Is this what you are talking about?
My Mate 10 Pro has no problem
