Photos App - How to select all photos?

[ascender]

I'm either being incredibly thick (very possible after a long day) or missing the obvious, but how do you select all photos on an iOS device?

I need to share all photos with another device by AirDrop before signing out of the device and wiping it, but for the life of me I can't see any way to do it other than manually selecting rows of photos, which will take me hours to do (accurately).

If someone could point me in the right direction that would be much appreciated!

Thanks!

Assuming you're using iOS 14, tap on Select and then drag your finger over the first couple of rows to see the blue checkmark, and then keep your finger pressed down while letting it scroll to the bottom. If it doesn't work the first time, try again. There's a bit of a touch to make it work.
