PLEASE HELP !!! ....I have bought this phone just 2 weeks ago...

I think the problem came from the same problematic devices. I decided not to sony again. Regretted. Take another device still continues.
After sending my phone for the seconde time for repair (the first time, they didn't do anyting), I was happy to see that they replaced the screen.
Now, the phone works normaly but I didn't have a phone for 31days. I even bought a phone 20€ :smileysilly:. So the conclusion of my experience is that it was a waste of time and i'm happy it's over. I hope the problem won't come back. One thing is sure, is that i will tell to friends and family to open this forum before buying a sony mobile. Every year or so I change phones and had only one phone that didn't work properly, but they replaced it with a new one. This is my first sony phone and my last one too.
I was trying so send my phone in because the touchscreen had the same symtoms as showed in the video. They told me it is just a software problem and I should repeair the firmware.
I read about the trick with the sunlight. No light outside.
So I tried turning on the backlight trick. I keept the display on when loading for some hours. And now it seems much better. Just a little insensitive at the right border. Running now for some day with backlite and brighter display settings w/o problems.
That mean the sola has a problem when runnin a longer time with dim light settings! Sad we had to found out by ourselfs and Sony does not seem to care that much.
A complete waste of money and time in buying SOLA. Has been replaced three times for three different issues. The lastest being TOUCHSCREEN PROBLEM. What a waste of time going to service centre. Totally disappointed. Am sure Sony people are not going to address its customers regarding this issue. NO MORE SONY, NO MORE WORRIES. BACK TO SAMSUNG.
The ICS update partially fixed the touchscreen problem but still there is a problem using the touchscreen. Before it was difficult to unlock the phone but now because of the Glove Mode feature I can use it now. There is still part of the screen the is hard to swipe, in my case it as the the left corner panel. I can't bring my phone to sony service center because I don't have my warranty. I bought my phone online. Buying new touchscreen LCD to replace my defective one is expensive so I just keep it that way. 
Yesterday I updated my Xperia Sola MT27i to:
Android version 4.0.4
Version 6.1.1.B.1.54
Now the back-button does not work.
I need to reboot my phone for everytime I want to get back. Tat is for every menu I enter....Frustrating.
Anyone that has seen this or have a solution for it?
Sonymobile, please extend your warranty, i bought my xperia sola in KSA last october, day before i'm returning to philippines. i thought it was only temporary, but after a week until now, the phone touchscreen not functioning well. i go to the nearest sonyservice center but they refused to fix it because the warranty terms, please help regard this matter, i really appreaciate it if you fix it without any payment. it is a factory defect, and it shows in this discussion.. i am still waiting answers from my previous emails.. please help me
Unfortunately, such a thing is not possible. Have the same problem as me. To be a general problem. I gave the court. Did you use a sony than never. It makes the left part of the defective devices. get well soon

I tried call the hotline, but the ans is they dont know more as no parts can be provided. Thaht's all!! How gd service of Sony!!! It is my 1st time use Sony since i saw the TV adv. Now, I know Japanese brand quality & service become that worse...Please consider more if you guys plan to buy.
