How to extract/backup your phone contact list and browser bookmarks (stock browser, not chrome)
Depending on your intended recipient the Samsung SmartSwitch application can do everything you want.

It can back up contacts, calendars, applications and almost all other data.

It's primary use is in transferring files to a new phone, but it also has a mode to transfer data to a backup held on your MicroSD card.

In order to simply backup data in the current version you will see an icon representing a microSD card in the top right corner of the application when you launch it, next to the three dot "menu" icon.

On the next page you will see either a list of backups or "no backup" if this is your first. Tap the "Back up" button at the bottom of the page.

Tapping that will bring you to a screen that allows you to select contacts, applications and images (and so on) to back up.

Your Calendar and bookmarks are stored under those applications. If you connect to Google calendar and don't use the on-device calendars then you will have a warning telling you as much when you tap on the ">" icon next to "Applications".

You can then transfer the backup to a new phone and use Smart Switch to restore it, or you can simply keep the history.

It also has a Windows version, presumably primarily intended as a backup tool.
