Unless newer versions of Android use an alternate file system, all of them will have a 4GB file limit because of FAT32. So your recording time will be limited only by your video recording quality. Recording at 4K resolution would eat up a 4GB file pretty quickly versus at 720p. As I said in the first reply, some may have a software limit on how long you can record any quality regardless of how much space you have. If you want unlimited recording time, you need to use a digital video camera instead of a photo camera or a cell phone.
