A software upgrade is a new version of software that offers a significant change or major improvement over your current version.
Before we get into upgrades, it’s important to know that some manufacturers are in the habit of adding different “skins, or user interfaces to whichever stock version of Android they’ve selected for a device.
As a result, Ice Cream Sandwich isn’t going to look or perform the same across the assorted technologies you and your friends may be packing.
A manufacturer may tweak the OPERATING SYSTEM to work with a tablet’s cameras or interface with a cellular digital service.
That’s what you get with an open source system. (But let it be said that there’s spirited debate among the Android community about whether all this customization is necessary or not
identify your operating system
To see which operating system you’re running, go to the settings menu and tap on “About Tablet or about phone.” It should display the current version of Android on your tablet or mobile phone
checkout the 3 upgrade methods
.From the settings menu: Tap on the “update” option. Your tablet will check in with its manufacturer to see if there are any newer OS versions available and then run the appropriate installation.
Visit the manufacturer’s website: Every reputable tablet or mobile phone manufacturer will have a technical support site that offers the latest updates and drivers for your tablet or mobile phone model.
Visit that website from your device’s Web browser, and you’ll be able to update other drivers as well.
Connect to your computer: Most manufacturers sell their tablets or mobile phones with a way of allowing them to interface with other computers.
Connect your device to your computer, launch its proprietary software and grab your owners manual. You can probably reload your entire OS from scratch in a few minutes using your computer.
Using manufacturer-approved OS upgrades will also help you keep your warranty intact. This is the smart, safe way to go. Now, let’s look at some of the other options for upgrading your tablets or mobile phones
The downside to manufacturer’s approved OS upgrades is that they’re often more conservative than some advanced users would prefer.
The manufacturer will not release a new version until it has been thoroughly tested and approved. And sometimes they won’t advance to a newer version (like going from Ice Cream Sandwich to Jelly Bean)
if the device’s hardware isn’t up to the task. That’s when many users start to take matters into their own hands to modify it.
You may have heard of :JAILBREAKING” for iPhones and iPads. The same thing is called “rooting” IN Android.
This is where users unlock the manufacturer-supplied firmware to install their own updates, customized operating systems and apps that factory-supplied operating systems failed to accept.
You will be able to flash your device with a custom ROM /firmware after successful Rooting.
NOTE: Trying to Flash your device with a custom rom could be as risky as betting the device in a contest: :before you proceed to using the ROM , do research for the compatibility of the ROM and your device make sure you found stories of someone who had tested the ROM with your type of device.. good luck
