I found my tablet turned off in the morning several times in a row.
I could not turn it on by pressing the power button. When I pressed volume buttons and the power button together however, it vibrated three times and switched on.
The battery was well over 60%. It worked fine for the day. But it would repeat the same problem next morning despite being fully charged before bed.
I always used the alarm clock function, so it got pretty annoying.
Additionally the tablet would switch off its display in the middle of watching videos or browsing the internet, especially when I am holding it facing down.
I can turn it back on by pressing the power button, but it happens way too often to use the tablet on bed.
I've been using it for about 3 - 4 month.
I disabled some of the default apps that I do not use when I first got the tablet.
Other than that I have not meddled with any system functionality.
The problem started about a week ago.

I was in File Expert this morning, about to back up my apps, and my screen locked up (I was just checking apps to BU, had not started it yet). The only button that works is the on/off, but it only turns the screen on and off. No power down, no back, no settings, nothing. SPG5, so can't do a battery pull (what was Samsung thinking?). I thought maybe my battery went to zero, but I have it on a charger now, still just screen on or off. Is there a reboot sequence?
HELP!
edit: Sorry for the panic. I discovered that if I looooooooong press the power button, it finally rebooted. Not like a typical power off, a hold for 5 seconds; this took a hold of at least 30 seconds. Screen did nothing for a while, then turned on, then turned off and rebooted. All is back to were it was...
Last night my phone was working fine. This morning I awoke late for my day because my alarm clock didn't go off, looked at my phone to figure out why and all I saw was a blank screen. Playing with the power button I am able to get it to a mode where the orange charging light turns on and the softkeys seem to respond (they provide haptic feedback at least). The backlight stays off, but I can tilt the phone around and see a cyan line stretching the width of the screen and I can manuever it up and and down using the volume keys. There are 10 items in this menu it seems since on the 11th click of the volume button the line jumps to the top of the page.
Can anyone help me? I've tried taking out the battery for 10+sec, I've tried removing supplemental hardware (sd/sim cards), I've tried on and off charger.
EDIT: It would seem the key is to loose all hope of it working, but continue to press the power button in desperation and after about 40+ attempts at power at this point it might turn on. I'm officially terrified I am going to wake up without my phone at any given day now =[
Rooted? Stock? Recovery? Rom?
Hi. I have an Xperia Z Ultra and it was running v510 till today. Everything was working fine. Then I updated to v532 and then when the screen turned off automatically, it went into SOD and didnt start. It took me 20 minutes to switch it on. I kept pressing the Power key for 5, 10, 20 seconds. Nothing happened. I pressed volume down + power and heard a vibration but nothing on screen. After trying the power button for the 15th time, it switched on. I checked the Backlight optimization settings and they were off, so I switched it on. Immediately after the next screen off, it again went into SOD, repeat same process
tldr;
Didnt have any SOD before 532, now have one every time. Also, are there key shortcuts to switch the phone on after a SOD because I keep pressing the power key again and again (and continuously) and nothing happens for a long time.
I am on stock, locked bootloader, no root, updated via Sony software, no errors. Didnt have any SODs on any previous versions. I have the non LTE model.

Click to expand...
Click to collapse
The reset button is together with the microsim and microsd slot, covered by flap... You need a sharppointing object to press it...
Same problem here, a few weeks after 532 update phone just powered itself off and now takes a couple.of minutes to boot.up. Did you manage to resolve the sod problem at all?

Enable "Optimize Backlight" again. It's a known fact that you'll get SOD's and "fake hang" at boot when you disable it. Enable it again and reboot. It should be much quicker.
So a week ago, I double tap my phone to turn it on and it doesn't. I try twice and nothing. I pressed on the power button and the screen did turn on, but since then, it's gotten so bad that neither the double tap nor the power buttons work. Sometimes, I use the camera shortcut to turn on the camera and Then go to the home screen. This worked for about a day, but then that isn't happening either. Now I find myself plugging it into the power supply to turn the screen and even taking out the battery and putting it back in. Since about a day ago, the screen won't turn on even if i get calls(any kind of call). When i'm on a call, the proximity sensor does it's job the beginning of the call, but When i want to end the call, it doesn't work and i have twist it or turn it on some other way. My phone discharged alarmingly fast, and i think it's because i had to leave the phone at very low charge levels. Also, i have a lot of apps, and all the ones that drain a lot have been deleted. So many bugs. No fixes. Please help
Update: I've reset my phone, no difference.
Flash with a stable rom. Or clear all settings do a wipe and reinstall.
Hello everyone so here's my story
Phone has been flawless until a few days ago never been so happy about my purchase.
I have had the phone for 2 years now no problems what so ever.
I started to notice the screen staying on all the time tried pressing the power button to put it into sleep and nothing.
If i hold down the power button it prompts me if i want to turn it off this rules out the power button not working.
Display setting-sleep after 15 sec
daydream is on
security is off and i also tried adding a screen lock to add the feature power button instantly locks also automatically lock is set to 54 sec.
i went into developer options and stay away is not checked.
Things i tried
I downloaded a app that puts a icon on my screen to put the phone in sleep mode WORKS! I am no expert but it seems like some type of trigger has broken between the power button and sleep.
I downloaded wakelock and nothing is running in background.
Did what i wanted to do last resort and did a full factory reset and recovery phone is fresh problem is still there.After searching for answers and reading many post i am at my last resort and posting for some help?
