Cutting/trimming video on your Android device can be done in the GoPro app. Once you have transferred the media from the camera to the app you can go into the app gallery. Select the video that you want and then choose the Edit option. From here, select trim. There are a variety of editing options, but if all you want is to cut a segment from the original video, simply select the curved arrow and an option to save to device will appear (also an option to share). The clip will be saved as a new file with the edit (trim) that you applied. It will have the same resolution/frame rate as the original. As far as uploading...Do you mean to GoPro Plus? If you are a GoPro Plus member and logged into the same account on your mobile device, the cloud upload happens automatically (as long as there is a connection). GoPro Plus members have unlimited video and photo storage available.
