[Q] Xperia Ray - Black screen after stand by... - Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A

Hi, first sorry for my english, I hope that it will be clear enough to understand my problem...
My Xperia Ray, updated to ICS, display a black screen (with backlight) when waking up after a stand by. I have to wait for undertermined time to have something on the screen, sometimes I remove the battery and boot the phone to be able to use it.
I updated it to last 4.0.4 ICS thinking it will resolve the issue, but it has not.
I can still use the phone when connected to MyPhone Explorer with the phone keypad, while the mobile's screen is black the MPE windows shows me the "normal" mobile screen. Everythings else works normally.
I'm afraid to give it to customer service, it was a SFR branded phone and I flashed it with a generic firmware.
Locked bootloader, sfr gave me unlock code for sim cards, lost my root with last upadte too.
Any help ?

Did it also occur on Gingerbread firmware?

Didn't try with GB, it happened when on ICS .562, SEUS update to .431 didn't fix the problem.

I have the same problem with my Xperia Ray.
It already happened on GB and now also on ICS.
The screen stays black if you try to wake it up after standby (doesn't matter if power button or home button ).
This happens around 80% of the time.
The only things that help are: Waiting a few minutes, taking out the battery, or hitting the power button like crazy and eventually the screen will show up again after around 10 times on and off.
I brought my phone to the service center of the shop 3 times and every time they tell me they won't repair or switch it because the hardware looked fine in their opinion (they don't switch it on there, the one time I showed them the switched on phone with the error, they told me they could see the problem but as long as nothing inside is broken 'it's not their problem' . I told my lawyer and now he is trying to get me a replace phone.
The problem even comes right after you factory reset so I don't think it's an app.
It happens without the sd card in.
I had an different homescreen launcher installed around the time it first happened, but I removed it and it still happened and I factory reseted and it still happened. So I think it has nothing to do with that?
I tried software repair with the SE Update Service and it told me everything was alright.
Does someone around here have an idea what could be the cause?

I brought it to SFR customer service (here in france) 2 time, the 2 time they just downgrade it to GB, diagnostic was "update problem". They didn't take in consideration what I told them.
One of the shop employee told me that the third time normally they have to replace it by another one. If they don't want to change it I think I'll mess up their shop...

This even happens on Xperia Mini
when ever i try to wake it up by pressing Home button or Power button
it takes about 3-5 seconds to wakeup
it should be instant isn't it?
I also experienced 2 times that even pressing
all the buttons doesn't wakes up the screen
but only back light, then i have to restart the
phone by removing the battery.:crying:

Me too !
I have tha same problem !! I can't take it esay..It's bad thing in my Idea! very disgusting :crying:

I've got the same delays on my Lww, sometimes my phone doesn't wake up at all, and sometimes it takes several seconds. I haven't found any solution for it, but it seems to be a Sony-specific problem.
Sent from my Transformer Pad TF300T using xda app-developers app

I have also the same problem from some days
tried to reset all with flashtool with no luck
the problem is also during kernel loading,tried different kernel,logo and cw doesn't appear 90%times

if someone is able to read in logcat file I have attached one here
thanks for any help

me also
i also have the same problem with my xperia x10

bad news for all of us.....

I turned the sound for messages and phone calls back on. On 'silent' the phone just vibrated.
It hasnt fixed the problem of the black screen completely, but it is happening a lot less for me.

Finally I brought my Xperia Ray to the shop where I got it for the third time.
I bought it 159 Euros in december 2011 (plus Sony gave me 50E back) and they refunded 270 Euro in november 2012 !
Not exactly a refund because I had to choose another mobile, so I took the Xperia T which was 430euro, so I had to pay 160 E for the XT.
Good deal for replacement of a one year old mobile ! Only problem is that I can't unlock the BL.

It is a strange hardware problem since the screen can eventually be turned back on, so maybe it is something in the firmware that is screwed up and doesn't get completely fixed by SUS. If I were you guys I would try this fix: http://forum.xda-developers.com/showthread.php?t=1492805
It may not work, but it is better than throwing your Ray in the trash.

I have the same problem. My phone (xperia ray) after standby or after reboot has black screen with backlight. At first waiting for couple of seconds and trying to wakelock would solve the problem, after few weeks to wake up my phone I needed it to reboot (pulling out the battery). Now I need few reboots to start the device with screen on.
I found workarounds like Llama combined with Nightclock (both from Google Play) for the screen never goes off, but this eats battery and also sometimes the screen would go off. I don't believe its a hardware problem because with this workaround the phone is usable few days (until Llama delay the "events").
Found a way to make a logcat from starting the device. Two are for unsuccessful startups (black screen with backlight) and one for successful (screen on).
I think the problem is in the kernel for not loading drivers, but someone who knows to read logcat will tell us/me for sure. I can't flash new kernel because the phone is with Bootloader locked (Bootloader unlock allowed: NO).
Kernel version is 2.6.32.9-perf
Stock Rom 4.1.B.0.587
rooted
PS. Sorry for my english its not my native language.
Just to add one or two more informations: even with black screen and backlight the phone is usable, like I can answer on calls, it vibrates when I slide to unlock... I also thought the problem is in proximity sensor, but if it was that case the touchscreen would be locked.

If you fully discharge the battery and after switch on,it start normally?

[Q] Unresponsive Touchscreen

Hello,
I'm new to xda-developers forums. My X10 mini pro is only 2 weeks old but I got this random problem that pops up from time to time. The touchscreen is not working. I can't unlock the phone when I took the phone out of my pocket, I can't enter the unlock pattern. Then it registers a wrong pattern. for example, the pattern to unlock my phone is:
12*
*3*
**4
sometimes it just registers
12*
***
***
or
12*
*3*
***
or nothing at all and it ends up that I'm being asked with the security question. It gets frustrating.
There's also this one time when I have an incoming call and when I took the phone out of my pocket I can't slide the phone to receive the call. I ended up having a missed call (good thing it's not an important call).
Any ideas on this problem guys? Have any of you experienced the same problem before? Are there any good practice/app to improve the x10 mini pro's capacitive touchsreen? The problems occurs usually when the phone is fresh from my pocket or I am out in the bright sunlight if that helps. I really need it to be much more reliable.
P.S.
Can't wait for the 2.1 update... Hopefully it supports 2.2 and other future versions too. I don't know why the music player has no repeat. And the camera haz no zoom. And there's something funny about the dialer but I just can't pinpoint what. (any idea if x10 family can support gingerbread?)
No one bothered replying??
Well, that sux.
Anyways, for an update, I've rooted my phone, overclocked a bit, managed memory,... so far so good. I think having the the phone in your pocket, butt-dialing overloads the touchscreen with a lot of input (even if it's locked, but lighting up) that's why it becomes unresponsive.
-----------------------
Hope devs crack the bootloader soon, the news from SE regarding the update is devastating.
Same problem here. I've had the phone for 48 hours and almost everytime I unlock the phone the touchscreen becomes unresponsive.
Any solution? Should I return it to retailer?
it looks like the CPU/Memory was on power saving (low performance), until you turn it on.
Can you wait before you enter the unlock code a few seconds(5~10 seconds) to know if the problem is solved?

doesn't work, once the screen is lock the only solution is to remove the battery.
Is your phone rooted? Since I rooted my phone, played with setcpu and autokiller, touchscreen performance increased a lot. My guess is that it has something to do with memory management. While android claims that it has hardcore memory management, you still need to kill apps once in a while.
Right now, whenever my touchscreen becomes unresponsive, I press the power button (to turn off the screen, not shut down the phone) and press it again (so the screen will light up). It becomes responsive again. Works everytime without fail. I hope this helps solving your problem.

[Q] Can't end calls in lumia 800

I have my lumia 800 for a week, and now its happening something strange.. When i'm in a call for some time, and i want to end it the phone doesn't let me. Its still responsive, i can go to the start screen, etc.. but the phone call remains on top with the message "ENDING". After a couple of minutes the phone freezs completely and reboot.
Someone had the same problem??
It's not happening always, but it's frustrating... I was having such a pleasant use and then this happens.. and i'm becoming a little sad and worried.
I dont's know if its a problem of hardware, it seems software because doesn't occur always.
Thoughts?

Yes, I also had some similar kind of problems today, i could not answer the call, after they called me about 5 times i could, but then could only speak a few words before the call stopped. Also i saw the call was still running after the caller had hung up. I wanted to retart the phone, but it would not start up again, then i took it loose from the charger , and it beeped and after a while it started up again by itself.After that it worked oke again.
I think they have to look seriously at the software, there is something wrong here i believe.
I've also had this problem of calls not ending on occasion. It seems inconsistent so far though. I'd be interested to hear if this seems to be affecting everyone or if it's only a small number of handsets.
I have the same prb. The screen goes blank and cant end calls. Has to force restart

For all WP7 devices the screen automatically goes blank when you are on a call and the proximity / light sensor detects your head up to the phone. However, if the screen stays off when you move your head away from the phone it means your proximity sensor (or software related to it) is faulty as it still thinks you have the phone to your head.
This happened to my HD7 after a nasty drop on a tiled floor the other day; the sensor was dislodged and permanently was set to the "on" position. I could only end a call by pulling out the battery, unless the other party hung up first. And every time my alarm went off in the morning the screen would remain dark and I would have to press the power button to get at the snooze button (this is because the sensor is telling WP7 that the phone is in a pocket or somesuch, and not to turn on the screen as the alarm could be accidently disabled or snoozed).
I fixed it by dismantling the HD7, resettling the sensors and blowing out as much dust as I could. Has been working fine since! I wouldn't recommend doing the same for your Lumia 800 though...
I dont think it is a proximity sensor issue. In doing tests, the sensor works perfectly for calls if I only have the screen off for a short period of time. If I hold the device up to my face for say 30 seconds, then the device usually freezes up and the screen goes blank, not allowing me to end a call. This makes me believe that it is a software issue that, hopefully, nokia can sort out.
Well i have been quiet on this topic as i wanted to see if the update fixed this problem BUT NO.
Today i made a call and it didnt ring but said connected i then pressed end and nothing it didnt respond infact none of the keys did anything my lumia just froze.
I couldnt even turn it off so i took the sim out and nothing still conected i just had a phone that was frozen with no way out .. so i had a usless lumia all day at work untill the battery died..I HAD NO PHONE ALL DAY !!!
I just hope it was not connected properly or my bill will be huge from t-mobile ..
This has happened a few times befor the update and always always when the signal is quite low it seems ..
But its a joke when im stuck with a usless phone all day ..
NOKIA SORT THIS OUT ITS NOT ACCEPTABLE
Hopefully this is a software issue and we haven't all received a bad batch of lumias with wonky proximity sensors.
Is there absolutely no way of reseting / rebooting the Lumia? you just have to wait for the battery to die??! That seems ludicrous!
i face the same problem many time i reset the phone by pressing power key long.
i find if i was in 3G network this problem some times happen ,so i switch off 3G and now it more than 3 days it never happen
Well to answer that question ...no its happened nine times last week, 3 of those 9 the phone is usless and you have to wait for the battery to die..maybe that's why Nokia gave us a short battery life haha, the other 6 times after about 7 min you can turn it off to reboot and the rest of the phone is responsive .. So 30% of the time when it happens U have no phone :[ even a long press of the power button does nothing
Same problem here... You can restart the phone btw: Hold power button for 10 sec, then release the power button and press it again...
This is a big problem for me, hope a fix comes in fast...
Thanks,
Samo
Im having the same issues here. Other than this its a great phone. Hopefully get it sorted soon.
same problem here, although never had to wait for battery to die.
long hold of power (10sec+) usually reboots the phone.
I keep noticing the problem when changing locations (inside/outside buildings) which is usually connected to switching to 3g - if it happens during a call I am unable to end it with screen being responsive and phone saying that it is ending call (for 30 seconds and more)
contacted Nokia regarding this problem.. they told me to reset my handset.. this is the only option they have... DUMB
same problem here... did someone find any solution?
nopes........

You can hold the power button for 10 seconds, this will trigger a reboot.
I'm relatively often facing the same issues, worth noting is that it does seem to connect the call as I have had customers tell me they heard me grumbling before the call got disconnected (so I gotta be more careful with grumbling )
Happened to me last night, just turned the phone off (power for a few secs then slide down) and on again.

From sleep to lockscreen LCD blank problem,any solution?

Hello.
When I leave my phone in sleep mode (screen locked and light off) and try to wake with On/Off button, sometimes I get a black screen with a faintly image. The touchscreen works and all the buttons, and if you click 2 times On/Off button - the image appears all ok. I tried to flash another stock ROM - all the same. Then I`ve unlocked the bootloader, rooted the phone and even did the S-off with wire trick (1.53 Hboot). Then I`ve tried 3-4 custom ROMs with 6-7 different kernels, from stock to custom, but all the same. Yes, I`ve updated the firmware file, also, but with no difference.
Well, I see that this problem is not so usual, but I couldn`t find any real solution. Did anyone have this kind of problem and solved it? Since I got this phone from another country - official warranty is out of the question, I need a DIY solution.
Any help is greatly appreciated.
THX in advance!!!

hmmmm, but when I get the OK image - it doesn`t flicker or go from dark to bright, it only has trouble to "wake up from sleep mode". even when i relock the screen quickly and don`t leave it unused for 2-3 minutes, the screen works OK every time....it looks like a software problem, but still I didn`t manage to fix it with all the ROMs/kernels/firmwares I`ve flashed....

Thinking about how to troubleshoot if hardware or software. When in sleep mode, instead of using the power button, I would have the phone plugged into a computer and use the " adb reboot " command to reboot the phone without touching the phone a few times and see if it lights up correctly. The first thing you should see is the boot screen, and if it works every time, then you do have an issue with your firmware. If you don't see that boot screen first every time, then as much as it sucks, I would guess there is a hardware issue.
Good luck, but this is the easiest way I know of to help determine what the issue likely is.
Minor update here, the first thing (at least on mine) that I see is the lock screen for just a quick second or two, then it quickly goes into the boot sequence. This is important as in "sleep" the ROM is running, so if the first thing you see is the boot sequence every time, and not the lock screen, then it points more to a software problem than a hardware issue. CM9 had an issue for the epic4g where you had to turn it off and on sometimes to get the keyboard to light. They found the issue in the firmware causing it.
Just wanted to make this as accurate as possible.
Wow so I am not the only person with this problem. The EVO 3D that I have was replacement phone that was given to me from Sprint from the first EVO 3D that I had which had issues with the digitizer. I received the replacement phone this past Tuesday and it worked fine for two days. It was not rooted and I did install the ICS update. On Friday morning I took it off the charger and went to work, while in the break room the screen suddenly went black and I could not get the phone to display anything after that. The Android function buttons at the bottom will light up but the screen wont, the phone also gets hot even with it powered off.
Long story short, I took it back to the Sprint store where they ordered me yet another replacement EVO 3D. Has anyone had to go through 3 EVO 3Ds or more?

Excellent thinking, I didn't think in that direction. I'll try this tomorow, since I'm not at home. My personal oppinion that it's a software problem but if I did all the above - what did I miss? If I flashed the firmware, ROM and kernel, what else is left untouched that could affect the LCD? Could anyone suggest a good kernel? Or can I downgrade the firmware, since no one had such a problem with GB?
just to inform all - I tried all soft solutions, but all the samo. finaly - I replaced the LCD and everything is OK.

SOLVED - Xperia Z Ultra - LCD Screen Issue while TURN ON - New Problem - UPDATE 8/15

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
http://youtu.be/1ZucFrMvg_w
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
Sent from my C6802 using XDA Premium HD app
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

[Q] [Help] Sony Z2, with lolipop, touchscreen not responding. (Software related)

As the title suggests my sony z2 will not respond to touch input. Yet strangely it will work for a day or two then it wont respond then a few minutes later it might be fine. But then on other occasions i need to let the battery die and then restart the phone for touch to come back. Originally i assumed it was because I recently had my screen repaired and it was a cheap part, but the fact that the screen doesnt work at random times makes me believe it is a software issue. If anyone else is having a similar problem or knows any sort of fix please let me know.

99% chance is that, it is your touch panel problem. Flash latest firmware through flashtool and see if the problem is gone. And why should you wait for full discharge? There is a power button beside your sim tray. You can also power it down by pressing and holding "power+volume up" button until it vibrates.
