The Samsung Galaxy Note 4 has received its first software update even before the company finishes launching the device in all of its markets. The update, which is said to be a small one, has significantly improved the device’s battery life, according to a report on Monday.

The new update, which comes with the firmware number XXU1ANJ4, has a file size of only 36MB and improves the device’s stability, other than boosting the battery life, SamMobile reported, adding that the update has been fully distributed and is expected to be available after the Galaxy Note 4 is released in other markets. Samsung used a similar tactic with the Galaxy S5 in April by rolling out a last-minute hotfix software update for the handset ahead of its global launch, Phone Arena reported.

While the Galaxy Note 4 is yet to arrive on major U.S. carriers, Amazon is already offering unlocked versions of the 5.7-inch handset. The online retailer is currently selling the international 32GB model (SM-N910) of the Samsung Galaxy Note 4 at $844.95 and $848.90 for the black- and white-colored versions, respectively. In addition, the gold-colored version of the Galaxy Note 4 can be purchased for $904.48.

However, Amazon is offering no warranty on the Galaxy Note 4 models, because the devices are imported units. The phones are also not expected to work on CDMA networks, such as Verizon and Sprint, SamMobile reported.

Meanwhile, the South Korean technology giant announced Sunday that the Galaxy Note 4 will be launched in India on Wednesday and will be available for purchase from Friday.

The Galaxy Note 4 is loaded with an improved 5.7-inch Quad HD Super AMOLED display with a resolution of 2560×1440 pixels. The device, which is powered by an octa-core Exynos 5433 processor or a quad-core Snapdragon 805 processor, also sports an advanced camera system, equipped with a 16 megapixel rear-facing camera and a 3.7 megapixel front-facing camera.
