Touchscreen responsiveness delay

Dear Nokia,

 

After switching from the 800/900 series to the 920, everything was great and perfect but something was unconsciously bugging me. Didn't take long to realize what it was: Pretty much every time I had to make the swiping unlock gesture twice in order to unlock the lockscreen. Why? Well, it's explained here.

 

Description of the problem

 

On the Lumia 920, after pressing the power button and immediately trying to unlock the screen, it won't respond to gestures.

 

This erratic behavior gives a bad user experience since forces the user to apply a second gesture to unlock.

 

This video shows in detail and compares a Lumia 800 vs Lumia 920: http://youtu.be/3y2awFPHbfM

 

Hope you will be able to reproduce the issue and fix it soon.

 

With regards,
Jandieg

Re: Touchscreen responsiveness delay

hi mate,

have you checked that you have all the latest Nokia system app updates from the Store? and have you tried performing a soft reset (pressing the volume down and power buttons together until the phone vibrates)?

Re: Touchscreen responsiveness delay

Can't reproduce this on my Nokia Lumia 920. It gets unlocked immediately with the FIRST attempt..

You may try a Soft Reset by Pressing the Volume Down + Power switch for about 10-12 seconds . this should not erase any data or alter settings. Recheck after this ..

Re: Touchscreen responsiveness delay

Soft and hard reset, even on 3 different ROMs (including stock).

 

Note it is not a matter of the first or the second time, its about the time you take between pressing the button and swiping. If you are doing things fast and want to power on and unlock immediatelly it won't respond. You need to wait about one second after you press the power button, which is not the idea.

Re: Touchscreen responsiveness delay

What I mentioned as 'Immediately' is may be much more quicker than the one I see in the Video posted by you ..

BTW, was this behavior same before the 'Portico' update ?

Re: Touchscreen responsiveness delay

Strange it does not happen to you. Are there multiple hardware builds of the 920?

I can reproduce it with Portico, but then flashed a non-Portico ROM and its exactly the same...

[ Edited ]

Are you doing it as fast as possible? (don't wait for the screen to light up).

 

I think it is a universal issue with all WP8 phones, I have tested so far on a bunch of phones:

 

Issue present on:

  • Lumia 920
  • Lumia 820
  • Samsung Ativ
  • HTC 8X

 

No issues with:

  • Lumia 800
  • Lumia 710
  • Lumia 505
  • Samsung Focus S

 

Not relevant, but I have also tested the same on other platforms:

  • Same issue with Galaxy S3
  • No issue with iPhone 5

Re: Touchscreen responsiveness delay

Hi I'm also getting this problem but worse. It sometimes takes between 1 and 5 seconds after hitting the unlock button to the screen becoming "active". Its really annoying.

 

Any idea why this is happening?

Re: Touchscreen responsiveness delay

Is it always happening or when the phone is connected to the charger ? I too experience a similar behaviour on my Nokia Lumia 920 but that is only when its on charging and that too not always .. so  though annoying when it does, not much bothered about it ..

Re: Touchscreen responsiveness delay

No, it can be at any time. It doesn't happen every time either, so its very random.

I've had the phone since December and its only started happening since late March. I thought it might have been something I installed but I've uninstalled everything I can think of.

I've done soft and hard resets and even gone as far as flashing the phone (as it bricked when I tried a factory reset) and its still happening! :smileysad:
