New details have emerged regarding Samsung's plans to upgrade its Galaxy S4, Galaxy S3 and Galaxy Note 2 to Android 4.3 Jelly Bean.

Samsung Canada and French mobile operator SFR have now offered new details about Samsung's schedule to upgrade some of its existing Galaxy flagship devices to the latest Android 4.3.

According to a new Mobile Syrup report, Samsung Canada's Vice President Enterprise Business Division Paul Brennan has confirmed that the Galaxy S4, Galaxy S3 and Galaxy Note 2 will get the Android 4.3 Jelly Bean update a bit later than the international versions.

The publication further notes that Samsung plans to update all of these three devices simultaneously "in one fell swoop," "across all Canadian carriers." Mobile Syrup speculates that this will most likely occur sometime in November. International owners of these devices, meanwhile, may get the update sometime in October.

The site also claims that Samsung has been working closely with Google and local carriers in order to "ensure a smooth rollout."

French mobile operator SFR, meanwhile, seems ready to announce the Android 4.3 Jelly Bean for the Galaxy S4, Galaxy S3 and Galaxy Note 2 as well. According to the carrier's listing, the Galaxy S4 should receive the update in October via KIES and over-the-air OTA), the 3G and 4G versions of the Galaxy S3 should get Android 4.3 in November/December via KIES and OTA, while the 3G and 4G variants of the Galaxy Note 2 will receive the upgrade in November/December, as well via KIES and OTA. SFR further lists an Android 4.3 Jelly Bean update scheduled to hit the HTC One in October.

All signs point to what was already speculated, specifically that the Samsung Galaxy S4 will be the first to get the Android 4.3 Jelly Bean update, with the 2012 Galaxy flagships set to follow shortly.

It remains unconfirmed at this point, however, when the U.S. variants of the Galaxy S4, Galaxy S3 and Galaxy Note 2 will receive the much-awaited Android 4.3 Jelly Bean update. Samsung did say that it plans to update these devices, but gave no exact rollout date for when this would occur.
