I bought a Xperia SL (India/Black) few days back..
from past 2-3 days i am experiencing that the bottom part of the screen is less bright than the upper half of the screen and the white background and icons appear brownish in that area ...:smileycry:
Overrall the screen is displaying warmer colour tones..
Is this normal with this phone... or am i the unlucky one... plz..... help...
Sony costumer care provides S/W reset as a solution .... 
Im on the 6.1.A.2.55 f/w
PS:- we dont expect such issues from a premuim smartphone dispite it being several months old... sony please improve your hardware standards or "Symbian Days" will come back.. 
I'm sorry to hear but I think that this will need to be looked at by a repair center to get it examined and fixed. Contact your local support team for more info about repair centers.
