Samsung Video Trimmer is an interesting tool to crop videos saved on your Android in a simple way. To do it you just have to run this built-in app and pick which parts of each recording you want to extract.
The way Samsung Video Trimmer works is quite simple and lets you crop any AV file in a matter of seconds. Basically you've got to open a video in the app and then set the start and end times in the interface.
To set the section you want to crop all you have to do is tap the two tabs. This trims the parts of the video you don't need. Another interesting aspect is that it gives you a preview of the crop before it gets saved to your gallery.
With Samsung Video Trimmer you won't have to turn to external apps to crop the videos on your Samsung device. In short, we can say we're looking at an app that delivers what it promises in a fast and effective way.
