Really I would this type of genious app beacuse it is most important and popular app in every country beacuse it show all type of vedio rather vedio present in phone storage or memory card also and in this app all type of vedio are supported rather it was low quality or high quality video and intersting fact is in this app their is option for adjusting brightness and volume.
And as we know this app is fully offline app and consuming not so much storage in mobile but this is advertising app so whole time it show advertisement while useing this app so this is an small problem other wise this is best.
