Subtitles may be not play automatically each time after it is imported and saved in media/video players. Save both video file and subtitle in the same folder. If the subtitle is downloaded or copied from a different file association, the name of the subtitle and the media file might be different. So we should import subtitle each time before playing. To avoid this and make subtitles play automatically set the name same for both video and subtitle file.
eg:- video file name
mechatrofice.mp4
Save subtitle file name as
mechatrofice.srt
