Problem| Screen galaxy s3
before few weeks my touch on the galaxy s3 stop working . just the touch .
i took the phone to repair and they say that the problem is in POWER IC .
they replace the POWER IC and the touch is really working .
but after the repair i see that when i go to lock screen i see that:
[Only registered and activated users can see links. Click Here To Register...]
what can be the problem ? its just when i go to lockscreen . in normal screen i dont see any problem .
its a little blue point and half of screen bright .
they say that the problem is in the screen, but when i gave them the phone he didnt have this problem .
maybe its problem with the software ?
i hope you can give me some solution .
thanks very much and good week
