OK Jaanu had only 15% growth on second day. The film collected Rs 4 crore net approx (40 million).
Taking the total two day collection of Rs 7.5 crore net approx. (75 million)

This was mainly because of xXx: Return of Xander Cage which had its full release on Saturday. It seems the film will remain lowland will not get good growth on Sunday and will be even tougher on Monday.
