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

For mine - it does not any changes is it pluged or not, while touchescreen not responding properly of course. After "sunbath" it still working properly for more than 30 hours.
it no longer work normal when plugged in.Taking to service center this week
believe it or no ,giving a sunbath works..i just kept it on sunlight(cloudy light) for 10 minutes and now its normal.Lets see for how long it works...
My Xperia stop working after 48 hours, just "sunbath" again for 5 minutes - and it working again. :smileyhappy:. But it ofcourse not a normal way to back phone to work (touchscreen). Hope that this is some software bug and will corrected. Big hope for ICS update. 
Thank you sunbath working forme too. When this problem raise up again can you install this software and draw everywhere of screen and upload screen screen shot here.
which software?
Screentouchtest
I want to see which part of screen is unresponsive,
you can actually perform a touch screen test using the service menu, dial *#*#7378423#*#* service test>touchscreen

Works fine, maybe its solar powered this why its name sola 🙂
now it makes sense... coz this problem starts when we have a very cold weather. I'll try it... somehow gave me hope. ^^
