I am trying to turn off my lock screen but it is not lit up as an option to select. It says "disabled by administrator, encryption policy, or credential storage." How do I go about being able to turn off my lock screen?

Why doesnt my s5 turn off when I get a notification or when I check the time On lock screen. This been happening for the past days. I had about 55% of battery and when I got off work it was dead. I then later charged my phone and noticed that when I get a notification on the lock screen it won't turn off right after the notification showed. when I turn on the phone to check the time on the lock screen it doesn't turn off. it would usually turn off seconds later. This has been draining my battery. if I have a full battery at night and disconnect it and throughout the night I get a text message the lock screen would turn on and never turn off,and then in the morning I'm left with a dead phone or a 3% left, or when I disconnect the phone it doesn't turn of neither. How do I set it back to how it was. I already factory reset?

I set up a new pattern for my lock screen on my Sony Experia Z2 and I have forgotten it. How can I unlock my phone without deleting any files? I need to keep my photos ect. I have tried to use Sony PC Companion but for that you need to have your screen unlocked and I can't unlock it because I don't know the pattern. I have also tried to enter a code in the emergency call section to try unlock it and it didn't work.

Dont know if anyone else is experienceing this issue but i can no longer use the power button to lock my phone. I cannot even use it to turn the phone off. but if the phone is off i can use it to turn the phone on so i dont see this as being a hardware issue at all. If anyone has experienced this or knows a fix please reply to this thread.

I recently sent in my Z3 to the Sony repair center for some reception issues. When it came back, My phone is locked with the message on the top left of the screen saying "SIM Is Perso Locked". I now have to enter a SIM network unlock PIN which I do not have. I have called Sony and they could not provide a code. I have received one from my phone carrier (Wind Mobile) but that did not work.Is my phone now locked to Wind Mobile? And how would I receive a proper unlock code?

Yesterday I changed my pattern but today when I am opening my phone the pattern is not accepted although i am 10000000% sure that this is it after trying 200+ times no message showed up to reset through google adding to that sending a password through my google device manager is also impossible due to pattern application...

Im a new user, just got the SE XPERIA RAY yesterday, the phone has a great feature of locking the screen during a call (whether initiated or received) until the user clicks the home button. however upon receiving calls the screen locks (black screen), the home button doesnt unlock the screen and it stays that was after the call ends, until it restarts or i remove the battery. i removed the battery, sim and SD card. I updated the software then made a master reset, nothing works... should i replace the phone? or is there something else to try?

When I press the key to access my mini pro, sometimes the previous screen unlock pattern appears. Obviously not very secure.

I tap "ok" and the message comes back again. The strange thing is that the message is in spanish (I have my phone in English and that the lockscreen photo has dissapeared and the xperia theme is there now.
It seems like the phone is working ok in the background, but I cannot access the homescreen.
I can take screenshots, change the volume, etc. and as I could access the phone's internal and sdcard I made all the backups as possible.

My new Xperia Z5 is on a constant reboot loop if it's plugged in to a charger or my laptop. I've already tried everything. I've tried pushing the "off" button underneath the sim card slot (I tried both ways including the 120 second method). I've tried plugging it into my laptop to use Sony Bridge to repair. Nothing works.
How do I perform a hard reset on the phone manually? I've tried to hold the power and VOL+ and this doens't work, it just keeps reboot looping. I see a red light and sometimes a blue light in the top left corner of the phone..
This just happened out of nowhere. The phone is 2 months new and I paid top dollar for it. I'm pissed off and have no phone.

I left my sony xperia z3 playing music while I sleep but when i woke up it showed 0% battery and it shut off. I tried charging it and it still won't turn on. I also tried charging it via usb through my pc but still nothing happens. I also tried pressing volume up key and power button while it was plugged in my pc and led turned red and now my pc can detect it but it is unrecognisable. I also tried repairing it via Sony PC Companion but I can't proceed to step 5 where you plug in your phone while holding the volume down button.

Yesterday I updated my phone. After the update I'm not able to start up the phone again. The black start screen (black screen saying SONY Xperia) pops up for a few seconds and then the phone turns off and starts up again with the same screen. It keeps doing this over and over again.
I've tried pushing the OFF butten/+vol button, but the same things happen when I try to turn if on again.
I've tried to connect it to PC companion, but since the phone turns off and on all the time I'm not able to connect it to the PC.

I've had Xperia Z2 for almost two months now, today when I was at work I noticed that it was off, although it had more than 40% of battery still remaining. I tried turning it back on but as it didn't work I figured something was wrong with it.
I tried hard reset and it did vibrate three times, but it still wouldn't turn on. I thought something drained the battary and waited till I got home to charge it. Now that I am at home it doesn't even charge, none of the LED lights work, it won't connect to pc companion either and hard reset now does nothing (as in, it doesn't vibrate 3 times anymore).
I tried volume up/down+power button combination, hard reset, held the reset button for longer than 15 sec, I removed sd card and sim, nothing works the phone is just lifeless. I haven't dropped it or used it intensely, it never overheat or anything of that sort.

I've got a big problem with my Z3. It was working just fine today I had about 50% battery, though I wasn't going to use it anymore. I'd just put it to charge. I thought I might as well give it a reset now and again as well as clear application processing etc. So I turn off my phone and plugged it in.
I have noticed an odd red blinking LED which I've not seen before (whilst charging), so I thought I might as well turn my device on and see if there is anything wrong. It seems my device refuses to turn on.
I've then consulted the internet to find any way I could fix my device. The only way I was going to be able to do anything was via Sony Companion apparently. So I set it all up and let Sony download was was needed to hopefully repair the phone. Followed all the instruction until I came to this.
No matter how long I hold the volume down button and plug the phone in, it just doesn't want to work. There are no vibrations even when trying to force the device. I've also tried to reset the phone via the hardware button located next to the Sim tray and that didn't work either.
So now I've just left it to charge via wall socket the red LED in the top left corner is still blinking as I'm typing this. Seems I'm stuck with a dead phone at the moment.

Just got my z3 a few week and start using it . Moved from IOS . I am having a few problem with my Z3. I can't find my problem in the forum. My Wifi is doing auto turn off. I checked on Wifi Alaways on . But as soon as i m out of wifi signal it will go off. I always forgot to turn it on as a result of it . Could it be from one of the app i installed ? I m pretty sure nothing wrong with the product as i can use it when the wifi is on.

I was on my Xperia z2 and the screen began jumping up and down before I shut the phone down and took my cover off to feel how hot the back of the device was.
At this moment, the device was charging and when I try ti turn it on, all I get is a screen mixed with lines of yellow, pink and green, almost like an untuned television.

I've seen a lot of discussion regarding the X10 not turning on after a failed update, but my issue seems to be different from all of them.I've seen people mentioning that their green light flickers, or the screen is frozen or displays an error message. Mine does NONE of that.Holding down the power button does nothing at all. The phone shows no sign of life. The LED doesn't come on, the screen doesn't come on, nothing. It does nothing.The battery is charged (and I even left it charging for over an hour - during which the LED was STILL off) and it will not connect to any of the Sony Ericsson software on my laptop.
