Samsung's Galaxy S3 was one of the most popular smartphones of 2012. Now, the new Galaxy S4 has come to us, which has been a biggest concern. Generally, Samsung Galaxy S4 has 5-inch "Full HD Super AMOLED", full 1080p, 441 PPI, 2GB RAM, 2600mAh battery, which can be a great media player for you anyhow. If you have some personal videos like AVI, MKV, VOB, MPG, TiVo, WMV, etc stored on your PC, you can transfer these files to Samsung Galaxy S4 for playback on the go.

However, we are afraid that uploading and playing AVI, MKV, VOB video files on Samsung Galaxy S IV is not so easy, because the Galaxy S4 video format is limited as other Android devices. Fortunately, we have a great tutorial for you- converting videos before transferring files to Samsung Galaxy S4, to get your AVI/MKV/VOB videos playable on Galaxy S4 without problems.

Preparations:
- AVI, MKV, VOB videos stored (externally-downloaded or from other source)

If you like, you can click on Settings you could easily set bitrate, frame rate, codec, channels, sample rate, etc to adjust parameters that affect video quality and file size for the video you prefer.
