Proposal

OI file manager is a great file manager for Android users. It is very popular and has lots of features that are designed for ease of user friendly environment. We can see it is popularity on Play Store having 5 million downloads. Today all users want ease and fast in apps. I had come here for the contribution to OI File manager for addition of Inbuilt image viewer and video player in it. What will it do, simply enhance user experience and attract more people to it. We don't need other gallery or image viewer to view images and video player for playing videos. If this feature will be implemented to OI File manager it will be more ease to do things with it. Nowadays this app prompt you to go through another app to open video and images but it should not be like that. It means using OI file manager we have to keep a another app or image viewer in our phone.

Mockups / Examples

Presently OI file manager is like this without these two features :
1)While opening image:
2)While opening video :
These features should be implemented in OI file manager like this :
1)Video player if integrated in OI file manager it would be like this :
2)Image viewer if implemented it would be like this:

Benefits

1)Video player :Users will be able to directly open video file on OI file manager without downloading any new software or app in our phone. Sometimes the video player we are using gets crashed so that will be major issue as nowadays all file managers are supporting this feature and how cam can be it not implemented in OI file manager for ease and user friendly experience.
2)Image viewer :Why to go to other app while opening images on OI file manager. This feature allows OI file manager not to be dependent on other applications and attracts users to it.
