my question is How to change default video player. I really need to change it beacuse that video player cant open all of the formats, so I can't open snapchat videos. Basically i just want to make snapchat videos work on my phone. Every time when i want to open snapchat videos i get : 'Can't play this video'. So i thought it's video player problem, but even if i got MX Player installed (or other vid players, i tried many of them) i can't open videos on snapchat. Maybe if I could change default video player or disable that LG video player snapchat would use MX Player instead.
