Hi hanbevmoh,
The message that the phone has insufficient storage is shown when the phone is telling the app there isn't enough space to save the file. There aren't any setting in the app or the camera that would be able to overwrite that warning. You may need to delete more files from the phone to open more storage or load if the phone uses memory cards to store files you may need to load in a new storage card.
The other option would be to transfer the videos to a Windows or Mac computer. If you want to transfer them to a computer our import software is available HERE. Once you are on the web page click on the Software & Drivers button and the current version is EOS Utility 3.17.0 for Windows computers or EOS Utility 3.17.2 for Mac computers. The instruction manual for that import software is available on the same web page under the Manuals tab.
