Default [Q] blurry fonts/texts [Xperia Go]

I updated my Xperia Go from gingerbread to Jellybean(6.2.A.1.100) with PC Companion and one thing thats bugging me is the blurry fonts. The fonts are pixelated and blurry and its very uncomfortable reading on these fonts. I have noticed this especially in Google Play, I did factory reset before updating and dont have other apps installed as of now. Is this happening to everyone else as well? Is there any fix for this?
