Samsung Quick Share is a fast file sharing feature similar to Apple's AirDrop. Interestingly with Quick Share, Google has integrated this feature into a fast file sharing feature that is universal for all Android devices. Only, sharing from Samsung Galaxy to other Android devices is limited.
This sharing limit is 5GB. Latest. Samsung has kindly increased this limit to 10GB giving users more flexibility to share files. The daily limit is also the same from 5GB to 10GB. It should be noted, this limit is for sharing using Internet access not offline.
Quick Share offline mode allows users to share files between Android or Windows devices without any file size limit. This 10GB limit will be received through the Quick Share update on the Galaxy Store which has been distributed in stages.
