Xperia X - Screen Issue when Enable Tap Twice To Wake Up Function - Help

[novnov]

Hi there ,

I got this Xperia X just 2 days ago and I notice some issue on the screenlock , wondering is anyone has a similiar issue and how can it be resolve ?

Below are my phone Setting :

1. Display --> Sleep ( 15 Seconds of Inactivity )

2. Lock & Security --> Screen Lock ( Pin )

3. Lock & Security --> Automactically Lock ( Lock Immediately after sleep )

4.Display --> Enable Tap Twice to Wake up 

Problem Encounter : After 15 Second of Inactivity , the screen turns dim / black (sleep) and lock . However , after a few seconds the lock screen with clock display will appear up again and goes off again ...... then appear again .... keeps going on & off ... I am afraid it will drain out the battery as well.

I had tried ' Disabling Tap Twice to Wake up ' depending on on/off button  to activate the screen . I do not see the locksceen with clock display appearing on & off . 

Had tried reset the phone to factory default , also facing the same issue itutation.

I had a Xperia Z5 with me it works fine .... after sleep mode it will lock and remains dark .

Anyone with Xperia X and having the same issue ?  And has a solution to it ?

Thanks.

Does this occur while charging? You can take a look here:

Hi, it do not occur when charging...

***Note correction on the above : it do occur on charging only when 'Tap Twice To Wake Up Function is Enable'.

Can you check if the same occurs in safe mode?

[novnov]

Hi. Yup tried in safe mode. It happen in safe mode as well...

I had also do a try without any security lock.... the screen is is facing the same issue ( dim in 15 sec of inactivity ...black .... lit up again at home screen ....dim in 15 sec of inactivity....black .....lit up at home screen again)

Now it seems like not a lock screen issue but its more of an issue when this tap to wake up function is enable...

Hi @novnov,

I'm sorry to hear this.

If I've understood you correctly this only happens when you have Double tap to wake enabled, changing the other settings that you mentioned makes no difference as long as double tap to wake is enabled?

[novnov]

Yes. It happens when tap to wake up function is enable. I tried in safe mode,  done factory reset &  software repair.  Problems still persists.  Anyone facing the same issue and have a solution to it?

Could you try enabling "Show touches" in Developer options and see if the phone seems to register any touch inputs when this happens?

To enable Developer options, go to Settings > About phone > Build number, tap 7 times on the build number. When you go back one step you can now find Developer options above About phone in the Settings menu.

Hi, 

I had enable show touches. And had monitor the mobile.  There is no touch input display when this happens.
