Xperia XA - Touch screen issue

[Sonyxanewuser]

I found that the top edge (esp. top right hand corner) of the screen is not really "senseable".  I need to press a little bit harder then other part of the screen in order to get the response.

I tried with both my glass protector off or on (apparently I have to get a new one after I took one off)

Should I just go to the Sony store and ask for maintenance?

Hi everyone.

After i played my phone on safemode for 25 mins (just simply used youtube app) then the problem occurred! All the area on the edge of the screen became less sensible and less responsive to my finger. This happened for 10-20 seconds. I need to press those areas alot harder.

I then used the diagnostics tool that came installed with my XA to test the touch screen but it works just fine.

So i think possibly the problem are:

1. The Sony OS has some bugs
2. Possibly Ram has problem

Please anyone used to have this same problem please share it with me.

My X Performance does the same, even during safe mode

Hey Pingbara, I'm sorry to hear that Safe Mode didn't work, that's disappointing. Same for you scalkie. Since Safe Mode didn't work, I think your point about the Xperia UI's code having bugs or the touchscreen is defective in that area. I don't know if RAM would affect the touchscreen as RAM is mainly used to store apps for multitasking but there's a good chance I could be wrong. Sorry for Safe Mode not work.
