Android

If you have an Android phone, here is some software that might be of interest:

Security/Privacy

• KeePassDroid - Password manager that uses encryption
• TextSecure - Encrypt SMS
• DroidWall - Firewall
• AdFree Android - Requires root, but removes all ads

Performance

• Only have wifi or GPS on while using it, turn it off asap after use.

Samsung

• Kies Air from Samsung Apps (allows you to exchange content on the LAN through a web server)

Backup

There are a few popular apps you should ensure you've manually backed up the shared secrets for, such as:

• Signal
• Silence
• Google Authenticator
• Whatsapp

You'll need adb for this. On Debian or Ubuntu:

sudo apt-get install android-tools-adb

then you'll want to make a directory to back your files up to:

mkdir android-backup

cd into that directory, and start by backing up all your installed applications:

adb backup -all # Consider adding -apk -obb -shared as well

and now you can also backup your internal sdcard:

adb pull /sdcard/ .

The above assumes you're in android-backup, otherwise replace the . with the directory you want to backup to.
