I started to notice that the photos taken using front facing camera was not that sharp. I thought it was due to beautify filter. But even if I turn of the filter and take pictures when there is some light source behind the photo coming out was very foggy. I couldn’t see any thing on the lens. What to do? Nearest service centre is a multi-brand service centre which is a 2and half hour travel from my place. Is multi-brand service centre safe?
