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?

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.

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.
Can anyone tell me is it currently all z2 tablets that have the issue or are some fine, if it is a fw issue then shouldn't all if them have the problem? I'm just in the middle if sending mine back for a replacement so just wondered.
Thanks

What do you mean by touchscreen wake issue? Double tap to wake not always working ? I know I sometimes needed to tap mine 3 or 4 times before it woke, in stead of two times. But I disabled the features since it seemed to be the main cause for my issue with occasional ignored touches. I haven't really noticed any ignored touches since I disabled it.
well if mine goes to display goes to sleep and i then either tap or press the power button to wake the tablet the screen sometimes either completely freezes and i have to really tap hard to the tap to be recognised, the screen also stutters about.
When was the last time you fully shut down and rebooted the tablet?
Is the severity of the problem different when double tap to wake is off compared to when it's on?
Does changing stamina mode options make a difference? Such as with the limited performance option on compared to off?
You have the latest (.402) firmware, right?
Yeh i am on .402, stamina mode is off, same thing seems to happen regardless if i double tap or press the pwr buttom, when it happens i then have to press the pwr buttom again to turn the screen off, i then press again to wake, and when i wake the 2nd time its back being nice and smooth again.
I'm basically having the same issues listed in the below topic which ive also replied in:

But have you tried disabling the double tap wake feature completely (in display settings) ?
And have you tried really powering off the device -not just turning the screen off, but holding the power button and choosing power off- leave it off for a minute and then power it on again ?
yes to bothm the double tap feature was off to start with when i was getting the issues, i turned it only only because i found it useful. i diont find the issues any different with it on or off.
also yes i do restart the tablet regularly, its not a constant issue it only seems to be if i allow the screen to time out.
anyway a new tablet has arrived today, i wont get to use it until later on though.hopefully it will be better.
Guys i was in my settings a few minutes ago and i came across a feature which enabled me to open up my notifications by just tapping the screen so i enabled it and went to the homescreen to test it! Upon tapping the screen the phone started maing a beeping noise and a blue line started scrolling continously downward on the screen! I cant turn the phone off ! I only seem to be able to reboot it which doesnt help! I needto power the phone off i assume and then maybe do a hard reset??? Advice needed please
anyone?
What setting did you access I don't believe anybody will be able to help if we don't know where you went and what you changed. The things you mention are very vague and don't really paint a picture of what is happening.
Also if you want to turn the phone off without using the on screen settings just hold onto the power button for about 10 seconds it should turn off, after that hold power, home button, and volume up to go into recovery to reset or what ever it is you please.
Also is it showing you an X and Y axis? If so then you just go into settings, developer settings, show screen updates and turn that off the grid should go away. I am not sure what your issue is but that seems like the most likely option.
I am not sure if this is a bug with 5.1.1 or not. I tried searched before coming here to post, but I haven't come across a solution yet.
Anyways, my phone doesn't have power saver on, smart stay is off, and I have my security set to fingerprint unlock.
To the issue at hand - My screen doesn't automatically time out if I press the home button or the power button to turn on my screen. In order for the screen to turn off, I have to manually press the power button. Otherwise, the screen just stays on and drains my battery. This wouldn't be too much of an issue if my butt didn't always press the home button while the phone was my pocket.
I'd really hate to factory reset or flash another rom, as I just finished installing all of my apps and whatnot after a phone replacement. However if that is the only option to fix this problem, then I'm okay with doing so.
Thanks ahead of time for reading!
**quick edit** - forgot to mention that if I receive a notification, that it turns my screen on and keeps it on until I press the power button.
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.
