but a new version Firmware did not arrive for all users, since different operator versions of firmware may differ in delivery time, while other users' smartphones themselves may not see the new firmware. In this regard, I wrote a small instruction on Galaxy update S III to Android 4.3 manually.

So, first we need it itself, you can download one on our website. For devices purchased legally, it is best to install a version for the home market in Russia, but there is no such version yet, so I decided to install the British version. It is not much different and also contains Russian, like any other European version. In the future, it will be possible to reinstall the firmware using the method described below and this will not lead to the loss of the official warranty for the smartphone. I also recommend reading the article to the end in order to avoid further discomfort that will inevitably overtake you after the update.

The procedure for installing the firmware is as follows:

1. run the program on a PC and make sure that the smartphone has enough charge;
2. enter the smartphone into Download Mode (at the same time pressing the "off" + "volume down" + "home button" keys), then press "Volume up";
3. connect a USB cable to the device;
4. in the Odin application on your computer, select files from the archive with the firmware:
   • for the PIT graph - a file with the * .pit extension;
   • for PDA - a file whose name contains the word CODE, if there is none, then you should know that this is the heaviest file in the archive;
   • for CSC - a file whose name contains the word CSC;
   • for Phone - a file containing MODEM in the name;
   • Note. If the files for the CSC, Phone and PIT graphs are absent in the archive with the firmware, then we sew exclusively by the method of one file, i.e. we indicate the location of the firmware in the PDA column, and leave the rest of the lines blank.
5. make sure Odin is checked for Auto Reboot and F. Reset Time ". If the location of the * .pit file was specified, then the "Re-Partition" checkbox will be set automatically;
6. press the "Start" button and watch how the firmware process is going on. The phone may reboot several times during installation and in no case should you disconnect the cable from it until the message “All threads completed” appears in the Odin log or the green information window with the inscription “PASS!” Lights up.

Average process Galaxy firmware S3 takes about 6 minutes, but can take longer. In any case, it is worth waiting for an inscription about the completion of the installation of the firmware, because an early interruption of the process can turn the phone into a "brick". As soon as Odin informs you that the firmware has been installed successfully (message “PASS!” In the Odin application), you can start installing the operating system itself.

Difficulties in Android installation 4.3 no, the system is intuitive and prompts the user to place the necessary checkboxes himself, and even if you miss any moments, you can always make changes in the smartphone settings. The phone is now fully flashed and ready to go.

Android 4.3 is quite different from previous version(Android 4.1.2), but we still have the same Jelly Bean, so it won't take long to get used to the innovations. First of all, the updated interface that the Galaxy S3 inherited from its own is striking. In addition, the standard Samsung keyboard and S Voice service have been updated, new screen and camera modes have appeared, and they were accompanied by a redesigned notification center and settings section. Another feature of Android 4.3 is support for TRIM (now the device should become faster), ANT +, clock and full-fledged voice control.

However on this moment Android 4.3 is not for everyone, as, being official, the firmware is still damp and sometimes buggy. In particular, I noticed that unlocking now takes more time, and sometimes during this process the phone may freeze altogether, after which it will have to be rebooted. After asking other users about this problem, I found out that many people experience such delays. At the same time, other users complain about other things as well. For example, the hang of the end of the call button.

In general, Android 4.3 can be delivered for review, but at your own peril and risk. However, I would still recommend waiting for the official version of Android 4.3 Galaxy S3 for Russia or firmware with fixed bugs. Fortunately, Samsung is already working on a solution to the identified issues.
