Galaxy Note 3 models running Android 4.3 were spotted this week.
Variants of the device destined for the South Korean market were found on DLNA's certification website with Android 4.3 as the mentioned operating system. The variant codenames are SM-N900S, SM-N900K and SM-N900L. The three models will launch on SK Telecom, Korea Telecom and LG Uplus.
There can occasionally be hardware differences between different international and U.S. smartphone models, however, software is normally the same. This means the U.S. version will launch running the latest Android system.
SamMobile was the first source to report that the update would run on the device.
"Samsung Galaxy Note III will ship with Android 4.3 out of the box. Samsung has just started testing Android 4.3 internally. #Confirmed," tweeted the publication.
Samsung sent out the invites to the "Unpacked Event" where the device will be unveiled earlier this week. The Galaxy S3 is also expected to feature a 5.7-inch display, 3GB of RAM and a Snapdragon 800 processor.
The Android 4.3 update was finally unveiled at Google's media event that took place at the end of last month.
The new software will roll out to Nexus devices immediately with other popular smartphones such as the Galaxy S4 and HTC One receiving it a bit later on down the line. However, the wait should not be too long for those users.
Android 4.3 comes pre-installed in the Nexus 7 successor that was also unveiled at the media event. The new software was demonstrated on the tablet.
The upgrade to Android brings new capabilities to the multi-user mode that is currently available on JellyBean-powered tablets. A new restricted profile feature lets tablet owners customize the kind of access other people have on certain devices. In this restricted mode, apps will be available to multiple profiles, but they will function differently. In-app purchases will not be available in restricted profiles so children will be prevented from making unwanted transactions.
