File Size limitation for recording video is removed in Android 11. It’s frustrated when recording long videos with 4K format. When it reaches the limit of 4GB, the video is split out into parts.
Reported by Android Police, although file size limit is removed in Android 11 beta, some apps are still not supported to record large file size. Unfortunately, Google Camera which is used by most people does not support large file size yet. But Open Camera can be used to shoot without file size limitation.
There may be other apps besides Open Camera. Because Android OS itself removes the limitation, Apps will support in the near future.
Google releases first beta version of Android 11 and can be tested in Pixel and OnePlus 8.
