How to Lock Samsung Galaxy Tablet? This article will not only show you the method, but will also delve a little into the OS that runs on the Samsung Galaxy Tablets.
Before we discuss how to lock Samsung Galaxy Tablet, let’s discuss the OS or Operating System behind Samsung Galaxy Tablets – the Android OS. This is related to the topic because the Android OS runs on all Samsung Galaxy Tablets, ranging from the very first (Galaxy Tab) to the latest (Galaxy Tab S 10.5), which means the procedure we are going to apply to lock some Samsung Galaxy Tablets may not really differ a lot to the other models. In fact, it may be the same or with only slight variations depending on the Android version it is using.
What is Android?
Android is a mobile operating system based on the Linux kernel and is continuously being developed by Google Inc. The OS is designed principally for touchscreen mobile devices. This include Smartphones and Tablets. All Samsung Galaxy Tablets and Smartphones use this as its OS. Given that fact, it is more likely that the method we are going to use here may also apply on Samsung Galaxy Smartphones too.
The method that will be shown in this guide is for the Samsung Galaxy Tab 3 7.0, which has the Android 4.4.2 KitKat OS. This method may also be applicable to other Samsung Galaxy Tab models. Just go figure.
Here is the Android OS version history. It will help note the changes made to the OS.
