Android 4.3 for Galaxy S4Samsung kept their promise made at the Mobile Unpacked 2 Event and has now released the first official Android 4.3 update for Samsung Galaxy S4 I9505, the LTE version. The first update was released in Germany, but the rest of the countries are going to get the update in a short while.

Let’s start with what’s new in this update. Samsung isn’t providing an official changelog, but the changes are pretty obvious. First of all, there is a major increase in performance and speed. The device moves a lot faster now and there is no more lag; this was one of the biggest issues when the S4 was launched. It is obvious that Android 4.3 is using the capacity of the quad core processor inside the I9505 S4 much better. The changes can also be observed with TouchWiz that is more fluid now.

DID YOU KNOW? Updato offers seamless and guaranteed phone unlocking for any device, carrier and region! It's quick and easy - try it now.

There have also been some changes that make the display look a lot sharper. Under the hood things look much better now. Maybe with Android 4.3 people will really feel that it was worth to pay so much for the Galaxy S4. It is finally raising up to its expectations.

Android 4.3 for Galaxy S4 also comes with plenty of new features. Here are the most important ones:

  • OpenGL 3.0, ANT+ and Galaxy Gear support.
  • Samsung KNOX now works and has its dedicated application and bootloader
  • A new Samsung keyboard was added
  • New Reading Mode that makes reading much easier, it is integrated with only a few apps for now
  • The camera firmware was updated
  • Some changes with the UI
  • Samsung Wallet was introduced as a default app
  • New Samsung Browser with full screen by default and other interface changes

For now the update was only released in Germany but we all know how Samsung releases its updates. We can expect by tomorrow to have a bunch of other countries to get the update.

    This update works well! In my opinion it was the most and effective update for S4. Speed and battery time raised enormously. Thanks to Samsung!

    Reading the post I noticed that you are talking about “the octa core processor inside the I9505 S4 much better”…this is not true – I am quoting from an Internet review – “The i9500 is the internationally-available 3G model with Samsung’s own Exynos 5 Octa processor, combining two quad-core processors together in a big.LITTLE setup; on the other hand the i9505 is the international 4G LTE model that packs Qualcomm’s Snapdragon 600 chipset that we’ve already seen in some phones such as the HTC One.”
    I would like to know if the ROM here is for i9505 or for the i9505…also states the same.

    Best regards.

      I appreciate your contribution! You are right, I rushed into writing this and I didn’t realize that i have made a mistake. What I meant was the’quad-core processor’ inside the Galaxy S4 I9505.

      This update is for I9505 using Qualcomm’s Snapdragon 600 quad core cpu. Galaxy S4 I9500 also received the update.

What's my model number?

There are several ways to locate your model number:

Option 1
On your device, go to Settings, then "About device" and scroll down to "Model number"
Option 2
Often times you can view the model number inside the device, by removing the battery
Option 3
Using Samsung's model/serial number location tool
