Latest firmware Samsung Galaxy S2Samsung’s second flagship was Galaxy S2 and tens of millions of people bought this phone. You will find below a list with the latest updates released for Galaxy S2. Even though Samsung only supports updates for 18 months on each device you can still get security updates to newer firmwares, however there is almost no chance that Galaxy S2 will ever get a new Android version (i.e 4.3 or 4.4 KitKat). It is important to keep your Galaxy S2 updated to the latest firmware if you want to be protected from the latest threats or simply to ensure a better performance from your device. Moving on, we’ll present you the official methods to update your Samsung Galaxy S2 GT-I9100.

How to update my Samsung Galaxy S2

Samsung Kies

First of all there is the official Samsung methods using their software, Kies. You can download Samsung Kies for free from Samsung, and then use it to search and install updates. You can also use it for other management tasks. You can read this in-depth tutorial on Samsung Kies for more info on how to use it.

OTA Updates

Samsung also pushes over-the-air updates, for which you don’t need to install any software. Just go to Settings>General>About Device>System Updates and check for new updates. Sometimes OTA updates are not available, so you should also check with Kies.
