[Android] F-Droid Nearby : High-speed wireless file transfer
F-Droid Nearby is an open source free gadget that allows Android machines to wirelessly transfer files at high speed even when there is no network!
The principle of F-Droid Nearby is to establish a local area network (LAN) through cell phone hotspots. After two cell phones use QR codes to identify both sides, they can transfer data in the LAN.
Thanks to the high specification of cell phone WiFi, which supports AC and even AX specification, the transmission speed is very fast, far better than Bluetooth, and also far better than WeChat QQ in most cases.
The use of F-Droid Nearby does not require Internet access, and it can function normally with or without Internet.
