SGP511 sony tablet Z2 wifi occasionally erratic and not responsive touch screens

SGP511 sony tablet Z2 wifi

Does anyone face the same problem as me? I tried with two brand new SGP511 SONY Z2 tablet and both exhibit same problem. Looks like it's a design issue.
 
The touch screen became erratic and not responsive on several occasions and I noticed it was when it's placed in a cold room about 21 degree C or when plug into a USB power that has 500mA rating 
This cause the pattern login fails and unit was lock out.

Re: Touch screen problem

New firmware has come out that says it improves the touch screen.

Re: Touch screen problem

Hi,

Here is one more unhappy Z2 tablet owner Face with rolling Eyes

 

I installed the new FW(17.1.2.A.0.314) on Friday and it didn't fix this issue. I also noticed this behavior on day one and started to seach similiar cases on web and here I am...

 

Sony, give us feedback how you're going to fix this. Are you going swap faulty HW to new or what is your solution?

 

PS. How this issue was not found in internal testing phase? How is that even possbile?

Re: Touch screen problem

Just a thought:

After the upgrade on my Z2 phone to the latest firmware, I discovered a rather sluggish response from the touch screen on that, and the solution there (it runs the same firmware as the tablet) was to reset the data on the Extended Standby Mode Controller and then restart the phone.

-Settings-Apps-All-Extended Standby Mode Controller-Clear Data

-Restart tablet.

 

(I am thinking of buying a Z2 tablet, so I thought I would check out this section of the forums as well)

Re: Touch screen problem

The touchfunctions works fine when I'm holding the tablet in my hand, but if I put it on a table it loose all sensitivity.

Re: Touch screen problem

Have you tried to reset the app-data for the Extended Standby Controller and restart tablet?

-I'm just trying to confirm if the findings on my Z2 phone would change anything on the Z2 Tablet.

Re: Touch screen problem

There doesn't seem to be an extended stand-by mode controller app on the z2 tablet

Re: Touch screen problem

Hmmm, how strange if it is not there......

The tablet and the phone seems extremely similar, but I'm not sure if it is a Sony specific or Android build in app on the phone.

 

Note: On my phone it resides under All apps (not running, downloaded or buffered), need to sidescroll to All to get in in the list, then scoll down in the list. -Perhaps it has another name on the tablet?

 

(on my Z2 phone, if set to my local language, it is called something like EcoModeController......)
