I just installed Android 4.4.3 on my nexus 4, and sadly MX Player does not support this android version.
Problem:
Solution:
Just go to play store And update your mx player. That’s all. Now your mx player will work as well as before. 💪
PS: Before reporting issue, just check for latest updates in play store. We usually disable the “auto update”. Update manually for latest release ❇:)
