[Q] S2 Touchscreen crazy click - Galaxy S II Q&A, Help & Troubleshooting

I bought my Galaxy S2 week ago on United States, but it's imported I don't know where.
I got it today, and when I tried setup it the touchscreen problem started.
I don't touch on screen but it "auto" click on middle left of screen, so, it's impossible use.
I tried restore to factory and no lucky to fix it.
When i put the S2 on charge ou USB cable connected on computer, the touchscreen "auto" click stop, but if i remove the cable connected, it return.
Anyone know why this? I can't return to EUA to change and need know if is software issue ou hardware.
Can I call to samsung on Brazil and ask about it to change or fix the problem? I need pay?
It's a new phone, I need fix this with Samsung or w/e...

Start listening if you ask questions. In this case: start reading. Drreality already gave you a good answer.
Second, drreality.

He said to send Samsung Repair Center, so, they can fix it on my phone or give me another new phone, my question is different, troll.

He wasn't trolling he just stated that you completely ignored the most logical answer you're going to get and if you ask a question listen to the answers.

Before you turn it in; dial *#0*#
Then run the 'touch-test'. So you can diagnose whether it's the screen itself!
If problem persists; still return to Samsung!

Best is to turn it in mate. For service. Glad to see the test worked.

Same Problem
hello, I'm facing the same problem, i bought my s2 a month ago with 1 year warranty, i faced strange issue, i was using the phone as a WiFi hotspot, then left it on the table and went to sleep, i wake up and the screen isn't responding, then i noticed a crack in the upper right of the screen, i know warranties exclude broken screens and damages caused by improper usage, although that i didn't cause the crack of the screen(no one would believe that) i went online and bought a replacement, it arrived 2 weeks later, i went online and checked on how to replace it, i did all the procedures and replaced the screen and everything went well and i got the phone functional again, but the screen went crazy with auto touches in the middle of the screen i tried everything possible by software and hardware, anyways i realized it has nothing to do with software, then by hardware i checked everything and all was right, any possible solution other than Samsung repair center?

because i think i have the same problem
i formatted everything like it was a new phone, same thing.
see the screenshots:
btw i enabled "show pointer" in developer options to see the touches,
as you see, all the touches is in the same exact column:
