If you were unaware that your windows phone had the ability to block unwanted contacts
through the Call+SMS Filtering option in your settings then this minor update probably will not mean much to you. But to the others who have been using this feature since it was released in the Amber update you will be excited to hear that it received an update to verison 188.8.131.52, which consists of general bug fixes and some minor improvements. Yes we know this is not big new, but it is nice knowing the Nokia is staying on top of their updates even when it comes to the minor fixes. Well if you want this update click HERE.
