blank screen but phone ON!!!!

Has anyone had this issue?
I have tried a few different ROM's and have had this problem on all, the phone will work but sometimes when the phone is locked and asleep you cannot get the screen back.
If you ring the phone it will ring but you can't wake the phone up (the screen is off).
If I then pull the battery and reboot all is well until the next time, which is random.
I will remove all my programs to see if there is one of them causing the issue, I don't believe it is the rom as it has happened on a few of them.

Have you wiped your phone when flashing the different roms? I've had it sometimes, i think it could be a ram management issue...

Yeh, I always do a factory/wipe, dalvik cache wipe.
I think it might have been TW4.5, I did some research and installed TW4 Manager I then updated TW4.5 to the latest Version. So far it hasn't happened yet but i'll give it a couple more days.
Thanks.

Yh ive been reading and TW4 generally accelerates the issue (because its a ram hog? not sure i dont use it) Im currently using Golauncher with system tweaks, but was told that nemus launcher and system tweaks was a better combination... Seems to be working, ive had less force closes or issues of that type

it's the proximity sensor. needs replaced.

I don't think so...
The proximity sensor is only used when your in a call. It should not have any effect when he tries to wake it from his pocket after a while...

Well i am on 2.3.5 and using golauncher and never had any problems. Still my best guess is the damn sensor. On samsung apps there is an app called sensors i think and that app tells u what is working inside the phone.

Sounds like a great app but seeing as the screen doesn't turn on that app might as well be useless in this case

No screen turns on, its just when it turns off it wont come back on...

I have the same issue with my SGS. Running stock version of JVT.
Wake up in the morning to phone alarm but screen is black. Pushing home button or any other button does nothing. Had this happen a few times now and only solution is to pull the battery

In order to help you we need to know what you are running currently and what you have tried to resolve the issue so far, can please make as detailed account as possible

It's seems that everybody have this same issue. I have exactly this same - phone is working - buttons are lit, but the screen is blank. I'm on 2.3.5 stock firmware.
Trying to solve this I already did wipe and even formatted the internal storage.
What's more interesting is that this same happens to my wife's Galaxy Mini (S5570) !!.
I can remember though that when my phone was on v2.2 about a year ago it was working ok.
small tip:
What you can do instead of pulling the battery out is to press the power button for about 10 seconds ( phone will turn off) release and the press it again for few seconds to start again.

You don`t need to press power again, just keep it pressed until you see the samsung bootlogo.
Mine has started to blackout too, maybe it`s related to some installed software. It worked ok still few months ago. My galaxy mini is working ok tho, has only few market apps installed.

The bug is called SOD (Sleep of Death). Apparently a Gingerbread only bug (I think deep sleep was introduced in Gingerbread).
Your phone is going into deep sleep, and can't be woken agian.
I don't know if there is a fix for it, but you could try search for SOD on these forum pages.

i had this issue on cm7 with neo kernel, but sometimes it responded after some time
i think its black magic made by apple and will kill our cats

As Herman76 said, this is the SOD, I used to get them quite frequently. I created a thread with a possible workaround. So far haven't got any new SODs.

Z1 SOD (Sleep of death)

This is a pain in the arse, I've had my Z1 for less then 24 hours and already had it 5 times as I change my display settings.
Screen is there just the backlight isn't switched on.
Argh Sony

What firmware are you on? Yeah, it sucks to have issues on a brand new handset especially at this price! Try to check if there's update available. I'm currently on .531 and haven't had any SOD so far.

i have no problem

If optimised backlight is switched off then it seems to happen anytime to change anything to do with brightness.

I have experienced this bug on multiple occasions as well since I first got the phone. The phone randomly goes to sleep but the backlight stays on. Then I am not able to unlock the phone by pressing the power button and I need to hard-reset it (vol up+power) to bring it back to life.
For me it happened once or twice already even with Optimized backlight checked

happened to me when i was trying to share a dinosaur effect photo in the camera app

I actually experienced the bug on a few occasions right now and can't see a pattern. It doesn't matter if I have optimized lightening on or other functions it will just randomly happen on different occasions.
I have just flashed the newest .534 firmware and soon after the same thing happaned again so I guess it has not been fixed as of yet.

Arrgh! I just experienced this screen bug . And this is for the first time in last 4 days of owning the phone. It occurred while the phone was lying on the table (battery 9%) & I picked it up to make a call, but the screen won't light up. Had to hard boot using vol up + power button. Have not touched the optimised backlight option (still checked). Hope sony fixes this asap!

DAMN ! I'm on 14.1.G.1.534 and I just got this ! it hasn't even been 24 hours yet since I bought this phone. terribly disappointed.this could be such a great device. hope it doesn't keep happening - Sony Xperia Z1 C9602 - wtf sony.

I've had this happen twice since been on 534 firmware and had to use the red button to force the device down. Very frustrating but I think Sony will sort it and all will be good.

i have just about had enough of sony to be honest, i cant believe this is the third sony device in a row where there is something wrong with it, i bought the xperia z tablet, the touch screen was way to sensitive until an update fixed it, i bought the z ultra and returned it because of the sod, and now this, i turned off my phone last night as i didnt want to be interrupted, try to turn it on this morning, the sony screen comes up, then a blank gray screen, rebooted it a few times with no luck, the last time i just left it and eventually it booted to the home screen
and just now, i opened the camera app, just get a black screen, open snapchat to see if the camera works there, nope, it says error with the camera please restart device, so i do, only to experience the sod again...
honestly, with my experiences with xperia, i have had enough, i can put up with mediocrity only for a bit, if i keep on putting up with this crap, it makes me look like a fool
stuff you sony

Same here, terrible bug. Screen is actually there, but backlight won't turn on. I have to position phones screen towards the light source in order to go to the screen settings to uncheck optimised backlight option. If it is checked I have to uncheck it to get backlight to turn on and vice versa. Sony, fix that as soon as possible 'cause you got some pissed Xperia Z1 users here!

Im with a uk model and still on the original 518 version, and I've been playing it around for several days but no SOD issue

same issue with z1 C6903
i using z1 with .534 also facing same problem for past a week. it is dead when phone calls in. have to hard reset too. come on sony, this is issue is not new. we need a solution.
mind you, the phone is not launch in my country but i manage to use it.

Hi All,
I am from India and using Z1 (C6902) and its been 3 days since using my phone and thank god, no SOD at all...
maybe since mine is C6902 thats why ... i dont know but no SOD here till now

I have noticed this bug after i rooted my z1. (root via kingo tool), before it was working ok.
So when power off button pressed, screen still active...
after some tries, i have disabled auto-brightness check box. its now more or less working.

You're buying products that are relatively new (except the Tablet Z) and expect no bugs at all? LOL I think you need to step back and look at the whole picture. To be honest Sony releases updates in a fast and consistent manner so you should be happy that do this. Even the Nexus devices have their share of bugs and always see people react like bugs do not exist. There will always be bugs and what you want from a manufacturer is to release fixes.

Hi, me too having this bug. I had this SOD twice since last 7 days. Had to do a hard reset both the times. Waiting for sony to fix it. I think its the jelly bean bug and not the Sony's firmware's bug but can be fixed, i think.
I am from india and on the latest fw. 534.
Please let me know if there is any solution to this available in the market. Thanks in advance.

Touchscreen problems

hey,
since one or two months i have some troubles with my touchscreen. Randomly it starts to press something that i didn't touch and when i stop touching the screen, the system touches from alone. mostly opening google now by swiping up the home button. it also types thigns in whatsapp or so. Sometimes when i turn on the phone the touchscreen doesn't respon. all those problems are solved when i turn off the screen for 5 secs and turn it on again. i am running eXistenZ v3, i also tried some aosp 4.3 roms and had the same problem.
Any idea ?
EDIT: because the problem is solved as soon as i turn of the screen and on again i am not sure if it is really a hardware problem, is it ?

I was just about to post with the same issue!
I replaced the screen and back cover on my Xperia Z back in August and it was running issue free for 2 months but after the update last month to 4.2.2 I started having serious issues with touch screen.
Random inputs, no response to touch, looping homescreens and random apps opening and worse.
I am torn between a hardware issue?
As when the USB cable is connected the problem seems to gone so I think there may be a slight voltage leak screwing with the screen?
What is the best way to ensure that it is not a ground/voltage leak issue?
Or
Or because the issue cropped up almost immediately after the last Sony update, is there a chance it could be a software issue?
I am running on Stock 4.2.2 and any advice will be much appreciated

I have noticed yesterday that my Z's screen keeps pressing a certain spot randomly. Its by the O / P when i use the onscreen keypad. I opened the note app and drew lines, and there is an actual break in the lines when i draw in that area. This happened so sudden. I didnt drop my phone or anything. I just noticed it while typing that the letters started to get jumbled.

I have the same issue but only on certain kernels, I'm using that XZK "Stock kernel" with dual recovery and it's fine now (Note: This kernel only runs on Sony roms) Also, not sure if it's related but if i leave my phone to charge over night, ill turn the screen on and the touchscreen won't respond at ALL unless i hard-reset...

It might have even been a corrupt update, if you run windows go onto the sony application and get it to RE update your phone see if it fixes, it might. And if it does, yay. if not, then atleast you've ruled that out, right?

Well I noticed a small distortion in the screen on a white background in the area that my screen was experiencing random touches, and today I pulled my phone out of my pocket....and 4 cracks spread all over my screen....cant use the touch screen now have to look to order a screen

[Q] Weird noise from either the speaker or vibration motor

Has anyone else been having weird noise issues with the phone when using the on screen keyboard with haptic feedback enabled?
occasionally, once every 5-10 letter inputs the phone produces a weird noise (similiar to the noise the phone makes when it vibrates, but louder with slightly higher pitch). I only began to notice this after the latest update.
It sounds like it is coming from the speaker

Mine started a few days ago with the same funny but annoying noise. Did you find a solution?

I have the same problem. It was getting louder and louder so I just disabled haptic feedback altogether.

Hi , had the same problem, a month ago. Turns out , as per Sony repair center the vibrator motor was not in place. Turns out this was all bull****. Cause they could'nt get it right , and had to replace the phone eventually.

Same problem.....

Oh snap, I've still been using my phone with that problem, but I think it may be software related because it started after the 4.3 update and also sometimes it stops works altogether but if I restart my phone, it's back to normal.

I had the problem when I first bought the phone, although I don't hear it anymore now though. Maybe the "motor" got into its place when I dropped my phone onto a concrete floor.

Hi Bro,
Personally , i would take it back to Sony. Started off being an intermittent problem on mine, eventually no amount of reboots or flashing 4.3 or 4.4 ftf would stop the noise.
I assume Sony know , its an issue so that's why they swapped my phone without question.

ZTE Axon Proximity Sensor bug

Hi guys
Just bought Axon and first thing I found is that proximity sensor doesn't do its work well at least on my phone. When I am on call holding my phone by ear the screen is till on unless I turned it on pushing power button. Does anybody has the same issue, is this a software bug which can be fixed with future updated?

My device was working great but recently developed this bug. I noticed it after my last playstore update to 6.0.0. Device also doesn't seem to sleep anymore so my battery life fell off a cliff. Going to try a factory reset.

My bug has gone but light sensor is not working well in most cases I have to adjust it manually. I got the same version of Google play as you do. To maintain proper battery life try to install cm cleaner or something similar.

Thanks for the battery saving tip will check it out. Unfortunately for me factory reset changed nothing annoying as hell having to manually turn off the screen for all calls.

I have the mini and I too have the proximity issue. Really annoying.
