FlashMyAndroid - 10 Things to do with your Nexus 7 when you get it

There are probably thousands of things you could do, but here are a handful to get you going...

Check out the gorgeous Tegra only games. You can download the Tegrazone app from the Play Store or just browse through Play Store itself. My favourites so far are Puddle and Galaxy on Fire 2 THD although Riptide GP THD also deserves an honourable mention.
Upgrade to Jelly Bean 4.1.1 – it comes with 4.1 out of the box (although newer ones may already have 4.1.1). You can upgrade OTA simply and easily using the built-in software update.
Check that you got your free film, ebook and Play Store credit (offer varies by Country). I received a Gmail from Google showing that I now had £15 of credit J The film and book appear on your JB desktop My Library widget.
Decide what to spend your free credit on. Favourites include Tablet Talk, Shadow Gun THD, Tapatalk (naturally!), Titanium Backup Pro, Max Payne mobile, Real Racing 2 (amazing visuals), Splashtop HD, Camera app (surprisingly it doesn’t come with a camera app!)
Check over your tablet for faults! The main issues seem to be lifting screens although I also bought one with a very bad screen backlight causing ghosting and “greying” out. Mine was replaced without fuss and the new one is fine.
Try using NFC! Check this YouTube video for details.
Root it. Easiest way I have found is using the excellent Nexus 7 Toolkit.
Install the free app Stickmount by Chainfire to access external flash drives (requires root)
If you still use “flash” websites then install a flash enabled browser such as Boat plus Adobe flash (see here).
Get access to your networks shares to watch all the movies etc stored on your NAS by installing CIFS.
