hey what is up guys I'm Kay PhD here and this is a 2013 Nexus 7 it's the first device to ship with Android 4.3 out of the box so it's 4.3 really that much better than 4.2 well I made a video not too long ago about how Google is taking back Android and really moving a lot of the major feature updates to the Play Store rather than an operating system updates so that leaves a lot of people thinking that Android 4.3 must just be this super minor update mostly under the hood improvements but an improvement is still an improvement so that any further ado let's go ahead and take a look at the top 5 improvements from what I've been using in Android 4.3 jelly bean number 5 is that Google Play games comes pre-installed in Android 4.3 so you don't have to go to the Play Store and find it so Play games is actually new to Android I went over a little bit more of it in depth in my Google i/o recap from this year which is when it was first introduced but aside from all the fancy leaderboards and challenges in side-by-side friend gameplay it has app data sync across devices hooked up into it which means you can get to a certain level on your phone of a game and then pick up your tablet and have the same game installed and continue from where you left off so as long as you sign into your Google account on both which you probably are you can get to level 30 in Angry Birds and then pick up your tablet and start level 31 without a hitch which is pretty sweet number 4 is Bluetooth and Wi-Fi improvements now a lot of these seem like behind the scenes changes but again connectivity is really important for these Wi-Fi only tablets in the Bluetooth Department you're going to have the ability to connect to bluetooth low energy devices so Bluetooth smart all you know little peripherals like wearable tech you know the fitness bands and the smartwatches and things like that that it's kind of a misnomer saying Bluetooth Low Energy as it doesn't actually refer to the amount of energy consumed by using the technology but it refers to the type of devices that you can connect to using the technology but allowed it again wearable tech like Google glass as a matter of fact actually use this so it's nice that it's included now and in the Wi-Fi department you actually get this always-on low-power Wi-Fi state because Wi-Fi is a much better more accurate way of telling location rather than firing up those big energy taking GPS radios so you can actually leave always-on Wi-Fi on in the background to give a rough locate which saves a lot of power number three is restricted profiles now Android 4.2 gave you the ability to have multiple accounts on a single Android tablet which was nice because you could just switch between them very seamlessly on the lockscreen Android 4.3 gives you the ability to control a lot more of what that other account gets to see in terms of data in terms of images and video and stuff in your gallery and basically all the applications that are involved so you can cut off a whole bunch of different applications from a guest account being able to see that's kind of nice if you like to show your tablet to your friends or share a tablet with other people I probably won't be using this all that much because I'm the only one who uses my tablet but if you happen to be sharing with a lot of different people this is a very useful feature number two is behind the scenes improvements specifically in the graphics department a lot of what makes Android 4.3 actually feel faster and smoother than Android 4.2 is in the graphics which makes sense because that's what you're looking at in Android 4.3 now supports opengl 3.0 which brings much improved graphics performance optimization and overall butter rendering tweak spring improved performance throughout android it's all kinds of things that go on behind the scenes that you may not think sound like a big update to Android but trust me they are welcome in the performance boost you end up seeing when actually using a device with Android 4.3 and number one again comes in the performance Department in what we'll call trim TR i.m trim is essentially a technology that keeps the on-board storage clean from garbage build up and in Nexus devices onboard storage is everything right now every time you install a new app or add something to your Nexus 7 it creates a data point and in order to keep track of all these different data points and clusters your operating system basically creates a mapping index across all these different data points to keep track of where to access everything and where everything is the problem is that without trim there is no way to clean up that index if you were to delete an app or a song or a file or a document which makes the index very garbagey very cluttered and and not clear and rough and incomplete and tied up and just just garbage but Android 4.3 enables trim basically system-wide which enables the operating system to tell when data points are no longer needed and can be deleted from the end he races all the garbage and ends up leaving your device's feeling newer and faster and more responsive again access times are going to be a lot quicker which essentially means that if you have that old Nexus 7 that's slowing down and feeling really slow grab that 4.3 update and it's like getting a new tablet so there it is under the hood improvements and minor OS updates actually contribute a lot to how much Android has grown in the past couple years if we didn't get those minor updates we'd still be back in the days of gingerbread or Froyo either way that's been it thank you for watching if you enjoyed this video feel free to give a thumbs up and if you want to see more videos like this or if you're excited for the full Nexus 7 review and all the coverage I have for that definitely subscribe because that is coming up very soon either way like I said thanks for watching and I'll talk to you guys in the next video
