Ok, so we're offering something a bit different with this article. The purpose of this feature is purely to answer your most frequent: “what does it mean in Android when…” questions. The idea here is that this article will help you understand a little bit more about what Android is and what some of its alerts & messages are trying to tell you.

Right, let's get to it.
What does Android mean?
Android is the name of Google's free / open source operating system for mobile devices. What this means in (near) layman's terms is that it's a collection of software that manufacturers such as Samsung, Sony and LG run on its smartphones or tablets. Essentially it is what is responsible for the layout and functionality of certain smartphones.
With Android as your smartphone or tablet's operating system you also typically have access to the Google Play Store, which means you can download millions of apps, and other media such as music, video and eBooks too. See all Android tips and tutorials.
A typical Android home screen looks like this:
What does blocking mode mean in Android tablet/smartphone?
Blocking mode is actually a feature that is exclusive to the Samsung Galaxy S3 and above. What blocking means is that you can turn off certain features and notifications on your Samsung Galaxy S3 smartphone - one recommended use for the feature is to configure blocking for when you are sleeping, so your phone will only disturb you in the middle of the night if someone calls you - meaning Facebook, Twitter, Whatsapp and all other less important alerts won't ruin your night's sleep.
What does merge my Android contacts with Google do?
This is one is useful if you use Gmail or simply want to back up your contacts with Google. What is does is store your contacts with your full Google account, meaning that you can access your contacts via your web browser as well as your smartphone. It also makes switching contacts to a new phone really easy as they are already stored with Google.
What does Android system mean?
Android system simply means Android (see above), if you're seeing this it's probably because you have gone into your settings in your smartphone or tablet and looked at what processes are using the most battery or hogging the most storage space. The Android System will obviously have a large percentage of both of these as it is what your device relies on to work, so don't panic if your mobile handset tells you the Android System is using 33% of your smartphone's battery/storage.
What does rooting an Android do?
Rooting an Android is the equivalent of jailbreaking an iPhone. What this means is that is removes all of the built in restrictions of your smartphone or tablet giving you full control of what apps are nstalled on your device and exactly how your smartphone or tablet runs.
Rooting is not something we would recommend to the average user as it requires a bit of technical knowledge to successfully 'root' an Android device, as well as disqualifying your handset warranty.
Rooting an Android is a popular way users remove bloatware from their handsets. It is also often used to update smartphones/tablets to the latest version of Android (before the manufacturer rolls out the update)
What does it means when it says Tab limit reached on Android?
This is one of those questions where the answer is in the question, but if you don't know what a tab is or how to remove one then you're a bit stuck.
A tab is a window within a web browser, and it is a feature that has been developed to allow people to keep multiple web pages open within the same web browser.
Often on Android a new tab is opened when you click on the internet browser app from the home screen, so the result is users reaching their 10 tab limit without even realising it.
Luckily the way to stop this message appearing is very easy. Simply open your Android web browser app and click on the icon that is two boxes with a number written in the middle of them, from here all you have to do is click on the 'x' in the top left/right of the tabs you wish to close.
What does bent red arrow mean on Android?
This means that you have had a missed call on your Android smartphone. To see whom it is from swipe down from the top of the screen and click on the red arrow. You can also remove this notification by swiping down from the top of the screen and pressing the Clear button located in the top right of the screen.
What does reboot system mean on Android?
System reboot on Android means the same as it does on your PC, and this is that it will restart your Android device (turn off and on again).
You may see this message after downloading new firmware for your Android device. It's nothing to worry about and rebooting your Android smartphone is a good way to clear its cache/processes and keep it running smoothly.
