Join Nick Brazzi for an in-depth discussion in this video Note about software versions, part of Learning Android Phone and Tablet Security.
- The content in this course is relevant to the two most recent versions of the Android operating system as of this recording. Those operating systems are known as Android 4.4, also known as KitKat, and Android 5.0, also known as Lollipop. As we go through the course, I'll point out situations where the options are different between these two versions of the Android operating system. Before we get started, you should confirm that your device is running one of these versions of the Android operating system.
To check that, you should go to Settings. So, I'm gonna hit the app chooser and then I'll flick over and I'm gonna choose Settings. I'm gonna scroll all the way down to the bottom in Settings and I'll hit About Phone. If you're using a tablet, this would say About Tablet. And from here you're looking for the bit of information that says Android Version. This says Android Version 5.0. So, I know that device is running Android 5.0 Lollipop. And at this point you may have already noticed something that looks different between KitKat and Lollipop.
The style of the app chooser and the Settings screen looks different. So, for example, this is how it looks on a phone running Lollipop and this is how it looks on a tablet running KitKat. If I go into the app chooser, go into Settings, scroll down, I'm looking for the option that says About Tablet, and it says About Tablet because this is a tablet rather than a phone, I tap on that and I can see that this is running Android Version 4.4.4 which is KitKat.
But again, you can see those cosmetic differences. The app chooser looks different. The Settings screen looks different, it's a darker color scheme. But those are just cosmetic differences. Unless I specifically point it out most actions within the settings work the same on both KitKat and Lollipop. Once you look past the differences in the color and minor layout changes everything is the same. So, for most of this course, and when I need to show something specific to Lollipop, you'll see this device, which is a Nexus 5 phone running Android 5.0 Lollipop.
And when I need to show something specifically to KitKit you'll see this device which is a Nexus 7 tablet running Android 4.4 KitKat. Now the differences between Android running on a phone compared to a tablet are pretty minor. There are a few differences that I'll call out specifically in the course. So, by using a Lollipop phone and a KitKat tablet our bases should be pretty well covered. Both of these devices have the standard Android install.
Now, the nature of the Nexus devices is that they use the basic Android OS without any modifications. Some device manufacturers add additional software and interface design on top of the standard stock Android software. That's why so many devices that run the same version of Android can look completely different. So, for some movies in this course I'll point out variations in other devices using a Samsung Galaxy S5. This device is running Android 4.4 KitKat however Samsung adds an additional user interface called TouchWiz to their devices.
So, let's see what that looks like as we double check which version of Android we're running here. And it works the same as the other devices but it just looks different. I'm gonna go into the app chooser. I'll swipe over and find Settings. I'll scroll pretty close to the bottom where I'll find About Device. It doesn't say About Phone or About Tablet. It says About Device. So, all of these options are pretty much the same as what we saw on the other devices but now you can see how they look different because the interface design is different.
But of course if I choose About Device I can see the Android Version and it's Android 4.4.2 which is KitKat. Now, your device might have completely different modifications installed by its manufacturer. Most Motorola devices are nearly identical to the standard Android software. But as you can see, the Samsung interface looks pretty different. It's not practical to show everything in this course on every device but I believe that once you see a particular feature on both the stock Android software and on Samsung TouchWiz, you should be able to locate that feature on your own device.
It might just take a little extra hunting through some settings. But most of the options you'll see in this course are the same no matter what device you're using so a lot of the times you'll just see the same device which will be the Nexus 5 phone. Although the operating system for Kindle Fire tablets and Fire phones is based on Android, it's actually its own separate operating system that was merely built from Android as a foundation. Amazon doesn't even call it Android, they call it Fire OS, therefore the information in this course generally does not apply to Kindle devices.
But some of the information in this course may help you figure out how the settings work on a Kindle Fire. You'll have to do some exploration and experimentation but some of the information in this course might be helpful to you. But just keep in mind that the content in this course really is not intended for a Kindle Fire phone or tablet. It's really intended for Android devices running 4.4 KitKat or 5.0 Lollipop.
