It goes about Xperia Sola flickering problems. In worse and in best light conditions screen is flickering. This problem is in all apps and system as well.
I am very dissatisfied because this issue. It is very disturbing. Sometimes is it so strong, that you get head ache ! ! !
This issue is well know with this phone - you can read about it on official sony-mobile forum:
