Japanese carrier NTT DoCoMo is probably the busiest carrier nowadays in the Land of the Rising Sun. We now know that it will be releasing the LG Optimus G L-01E next week, but those who would prefer another brand of South Korean phone now have those alternative options.

The Samsung Galaxy Note 2 and an upgraded version of the Galaxy S3 known as the “alpha” will be released this winter and will run on NTT DoCoMo’s Xi-LTE network. The two new Samsung phones will come with Android 4.1 Jelly Bean out of the box.

The Galaxy S3 alpha (stylized in lower case, apparently) is basically the same as the usual Galaxy S3 except for Android 4.1 out of the box and a faster version of the quad-core Exynos 4412 processor. This CPU will run at 1.6 GHz instead of the usual 1.4. Other specs, just to provide a refresher, include a 4.8-inch Super AMOLED HD display, 1 GB RAM, 8-megapixel rear camera and 2,100 mAh battery.

The Galaxy Note 2 will be out by next month, perhaps around the same time some of the American carriers release the device back home.

It will also have a 1.6 GHz Exynos quad-core but this time will be backed up by 2 GB RAM. The Galaxy Note 2 also features a 5.5-inch Super AMOLED HD screen, 8-megapixel rear camera and 1.9-megapixel front camera with support for NFC. The battery is rated at an impressive 3,100 mAh.
