It can help them create applications for the stage faster and less demanding than if they were utilizing a gadget with a maker skin installed, and that is something worth being thankful for. However, regardless of whether a designer or normal buyer purchases a Nexus, either has the advantage of side loading programming updates directly from google. At the point when Google is working on upgrades to Android, its building them to work particularly on Nexus gadgets. This implies when Google lunches an update to Android itself, it will come rapidly to the upheld Nexus gadgets as opposed to it being adjusted to keep running on gadgets from different makers. Among Nexus updates there are quick and slower approaches to get the updates onto your phone or tablet. Let us take a closer look and see different ways.

Before we start side loading the updates it is very important that the user have some kind of primary knowledge of android SDK and command prompt windows or LINUX. There is a possibility that things may go wrong harming your device in the process. You can easily get Android SDK from any android development website with the complete information of how to download it and install it. You need fastboot files and adb which is located in the platform folder.


  • The first and foremost thing that you need to do is go to the nexus setting and scroll down then click on About phone/tablet
  • Now what you have to do is be a developer and in order to do that you will have to click the build number seven times in total.
  • After this go to settings again and click on the option named developer option.
