Nexus Media Importer

Android App Recommendation

Nexus Media Importer is an app for your Nexus 7 (2012 and 2013) and other Nexus devices to use external media storage like pen drives or SD cards via card readers. This is the first paid app that I am recommending because this is the only you option by which you can connect pen drives to your Nexus devices WITHOUT rooting them.
Of course, the other way, which is free, is by rooting your phone and then using one of the many third party apps available.

However, if you just want to access photos from your pen drive, then a free version of this app is available, called Nexus Photo Viewer. It lets you view the images saved in external storage.

Please note, you will need an OTG cable to connect pen drives to your Nexus, which is easily available these days, even at small mobile shops, for around Rs. 100. Or else, you can order one of the 'hybrid pen drives' coming in the market.

Make your Android look like Windows Phone 8

App Recommendation

Launcher 8 for Android: If you are bored of your default Android look and want to have the Windows 8 theme for it, 'Launcher 8' is the app for you.
It is a free app and you can get on Google Play. In case you are new to launchers, these are kind-of themes that will provide your phone a whole new look and feel, including icons. There are many other launchers as well, my preferred is 'Smart Launcher', though for Lumia theme, Launcher 8 is the one.

NES Games 64 in 1 - Mario and Contra for Android

App Recommendation

Get nostalgic! Return to the games you grew up with - Super Mario, Contra, Islander, Galaxy, Spartan and all of those - right on your Android smartphone. Now, this has only increased my love for Android.
It has the same old 8 bit visuals and exactly same tunes with a joystick like floating controls.

It is available on Google Play for free. Go to Play store and search for '64in1'. Thanks to the developer Jessica Dwyer. It works on tabs and phones smoothly and has a very small size. Enjoy!
