Android file transfer without USB cable, pulling out the microSD card, or using 3rd party apps My android phone's charging port died, so I am looking for a semi-convenient way to transfer files without using any 3rd party apps. Is it possible?

I already have an SMB share configured on my NAS, and a couple Windows computers. I have a WiFi network and a Bluetooth radio in my pc, but I'd much rather not use the latter as I've only seen abysmal transfer speeds from it.

P.S. I can still transfer files with the microSD card, but accessing it is onerous.

Fortunately, wireless charging still works on my Samsung Galaxy S8+
Bluetooth (Phone to PC)
Enable Bluetooth (BT) on both devices, tick the checkbox on phone to make it visible (Phone BT settings), pair phone to PC (PC BT Settings, add new device).
On Phone, View files in file explorer, if possible zip them, then share, send via bluetooth
On PC, run fsquirt, recieve files
On Phone, select your PC, and wait for the transfer to happen.
Tip: Laptops generally sit on their BT radios
Note: Bluetooth speeds vary depending on devices - a colleague's S10 transfers faster than my J7P
Google Drive (Phone to PC via Cloud)
This involves google drive or any other cloud storage provider as a middleman. Suitable if you have a Hi-Speed internet connection
Files By Google (Phone to Phone)
Note: This requires a second Android Phone, and assumes both came installed with Files (by google) - Mine did
On both phones, open Files, and go to Share
Follow the steps to setup your name and send files!
