Lock screen lag.

Hello,

I have a couple of problems with my Z2, Facebook videos not working, silly things however most pail into insignificant when compared to the lock screen problem.

I unlocked my phone and the screen turned black, the phone works you can feel it vibrate and pay sounds by the screen is blank. I can take pictures and use buttons as I know ruff locations but screen is black. This has only happens twice in 2 months but the lock screen is degrading daily, when I am entering my lock pattern it is slow and very clunky. Once I entered it correctly it then won't unlock for several seconds.

I am using the standard lock screen with a pattern pass. I haven't had a chance to try a number entry pass but I will get back to you.

Hope you can help.

Andy.

Re: Lock screen lag.

You won't be able to do it by default,sorry.You need a 3rd party lock screen app.

Re: Lock screen lag.

I recommend you do a factory reset or complete software reinstall from SUS.

 

What do you mean the screen is black?

Can you still see the status bar?

The lag can be due to some task managing app or power saving app.

Try unintalling those (If you can)

Re: Lock screen lag.

Hey,
I will do a factory reset tomorrow.

The screen is black the same as when the phone is switched off, no light at all or icons. It's like the screen doesn't power up.

I have no task managing apps other then the stock ones.

Thanks for the advice.

In that case it can be a hardware defect. The only reason I thought status bar appears is because I thought you could see the lockscreen when you turn the phone on, then the screen goes black after unlocking

Re: Lock screen lag.

Hello,

 

Sorry for the long reply, I wanted to see if factory reset fixed the problem and didnt wanna do it once. I have done the reset and it seems to have made a difference, i am sure this may occure again at a later date but we shall see.

 

Before resetting the phone to factory settings I went into the bug centre in settings, it said recent crashes where from "System UI" and it was crashing almost 5x a day, a couple of other app crashes but things I caused. The System UI was reset on each occation. I then did the screen check and touch screen check, both passed with flying colours!

 

I believe this was caused by a BUG in the OS/Sony custom UI. I do however belive if there was a way to simply reset the lock screen app then that would have done the job as once the screen is unlocked its perfect, I have never had a problem with it!

 

If there is a way of doing the above if you could let me know so if it happens again I can try that.

 

Thanks for the help community. 

Regards,

Andy

Re: Lock screen lag.

Hopefully it shouldn't happen again but if it does try this first: Main menu > Settings > Apps > All > Xperia Home > Clear data.

 

This will reset the homescreen back to its original layout but won’t delete any personal data.

[solved] Lock screen lag.

I solved it by installing Xposed and the GEM Xperia Xposed module.

 

I then enabled the AOSP lockscreen and got rid of Sony's one.

 

All lag is now gone!!!!!

Re: Lock screen lag.

Have you updated after the backup?

About the pattern or PIN,just go to settings-security-screen lock and there you should have it.

Re: Lock screen lag.

Hi, go into SETTINGS......SECURITY.....SCREEN LOCK.....it will ask you to unlock the screen whatever way you do it at the moment, then give you the options to choose PIN/SWIPE/PATTERN etc..
