Samsung Galaxy S2 upgrade to Android 4.1.2 Jellybean

I have just successfully upgraded my Samsung Galaxy software to Android 4.1.2 Jellybean and this is how I did it.

Firstly, I was thinking of upgrading my Samsung Galaxy S2 to a Galaxy S3 or even an S4 when my two year contract expired, but after I was quoted expensive upgrade prices I decided to hold off and I reverted to a basic £12 a month deal until prices hopefully reduce a bit.

I like my Samsung Galaxy S2. It’s in great condition but the software is looking old now and I really wanted the latest Android software to run on it. The new Instagram video App needs at least Android 4.1.2 to operate so that reason alone is a good one to upgrade.

Anyway, this is how I upgraded my Samsung S2 GT I9100 to Jellybean 4.1.2. It was a very simple process but it took me at least an hour, but I think it’s well worth doing because the new software is a big improvement.

First, I connected my phone to my PC using a USB cable and I opened Samsung Kies on my PC. I was prompted to update to the latest version of Samsung Kies and this took two attempts before I had the latest version. I then backed up my phone using Samsung Kies and this took about 15 minutes. You can restore the settings of your phone if something goes wrong using the “restore” function of Samsung Kies.

Once I had done a back up I just followed the prompts to upgrade the firmware on the phone. Prior to completing the upgrade you have to unplug your phone from your PC and connect it again and this completes the installation of Android 4.1.2.

When Android 4.1.2 is installed your Samsung S2 will restart and there are several settings to go through before it is installed correctly. The whole process was quite simple, although I did nearly give up when Samsung Kies froze when I was updating to the latest version of Kies. I’m glad I tried again because I’m really pleased with the upgrade to Android 4.1.2.

The only negative so far is that my phone contacts were filled with hundreds of contacts that I didn’t want so I went into the settings and put a tick in the option to include only contacts with a phone number and that sorted the issue but there are still duplicate contacts in my phone contact list that I will need to sort out manually.

Android 4.1.2 Jellybean is smooth and fast with no lag that I can see. It is easy to use with several new features that I’m pleased about. Reports say that battery life is extended but I’m still testing that and I’ll update this post when I have more information.

Upgrade your Samsung Galaxy S2 to Android Jellybean and you might not need a new phone !
