Android L still has a few tricks up its sleeve – specifically, in the Status menu. If you go to the About section of settings and tap on Status, Android L allows you to copy any of the values listed there with a long-press. Neat.
This isn't a huge improvement, but it'll make it much easier to grab your IMEI, MAC, or serial number (it comes up occasionally). There are a few other bits of data in this menu, but they aren't as relevant. Whichever line you press is copied in full (no selection handles). Oddly, this only works on the Status screen right now – not even on the About screen where the kernel and build info are. Maybe that will change by the time L is finished. It would be nice to copy text from any settings screen.
