Android Marshmallow has finally arrived.

First announcedat Google I/O, the company already teaseda bunch of cool features.

Here are some of the sweet features Google didnt announce.

Right now, Android Marshmallow is only available for certain Nexus devices.

If you havent received an update yet, heres how toskip the line and update manually.

The one key exception, though, has always been app data.

Of course, it comes with some limitations.

For starters, only 25MB of data will be backed up.

That should cover things like your tweaks, but it may not include the 5GB of music you downloaded.

Developers can also choose to opt-out of including certain files, or kill the backup entirely.

This is a good thing, as there arecertain types of apps and datayoudontwant backed up by default.

However it does mean there may still be a few things you have to manually transfer.

The problem is that developers can still opt out, and most so far have.

So any developer that hasnt updated their apps wont use the backup.

Moreover, devs can choose to opt out of the backup system if its not working for them.

While the backup system is great, dont expect it to work in the short term.

Thats a nice feature, but it also leaves you scrambling to find things every now and then.

In Android Marshmallow, you might finallycustomize which tiles appear in quick configs.

This is one handy feature of the new hidden System UI Tuner.

Youll then see a toast notification saying that System UI Tuner has been added to your tweaks app.

Open it up and youll seen option called Quick tweaks.

Use this to reorganize your quick controls shade.

Open up the Tuner in your tweaks app and unlock the Show embedded battery percentage toggle option.

you could also use the System UI Tuner to hide icons in the system bar.

Apparently no one really cared about phones, though, as Google has changed this behavior.

Now, when you swipe left, you canperform a voice search.

This is probably a lot handier than opening the phone app, and will result in fewer butt dials.

Butt searches, however, will see a marked increase.

Your SD Card Will (Finally!)

This is particularly important since Google has been making ita bit harder for developers to use SD card storagerecently.

In other words, having an SD card shouldnt come with any weird penalties anymore.
