I build to android quite a bit

For whatever reason the farther into the day the longer it takes to build... It is not associated with my computer (restarted it) nor the device (also restarted) but for whatever reason the process that takes a minute or two in the morning takes about 5 minutes in the afternoon....

ANYWAYS

why does unity

rebuild all the assets, and scenes if nothing has changed

• there should be some detection in unity that handles this... is there a preference somewhere that will allow me to turn this on?

I can't imagine a software as robust as Unity claims to be not taking this into account
