The Exynos 5 Octa processor in some Samsung Galaxy S4 models is compatible with LTE networks, according to a tweet from the company.
"@sammyhubcom @iNicc0lo Update: The Exynos 5 Octa supports LTE and all 20 bands," Samsung tweeted on Thursday.
The news seems to confirm that Samsung's decision to use two different processors in different models of the Galaxy S4 is a supply issue, not a compatibility issue.
Initially, it looked like Samsung was using the Exynos processor in countries without LTE networks, amid rumors that the Exynos wouldn't be compatible. Instead, Samsung is using the Qualcomm Snapdragon 600 processor.
Later reports showed Samsung is using the Snapdragon in 70 percent of the first 10 million S4s to hit the market. Now that we know the Exynos could work worldwide, it's apparent that Samsung is using the Snapdragon to fill holes in its supply chain.
Mass production for the Exynos 5 isn't scheduled until the second quarter of the year, after the S4 launches, so Samsung will probably start putting the Exynos in later shipments of the phone, once its confident its supply can stand the demand.
Performance-conscious consumers may want to wait, since recent benchmarks indicate the Exynos 5 is considerably more powerful than the Snapdragon.
The Samsung Galaxy S4 features a 1.6GHz eight-core Exynos 5 Octa processor or a 1.9GHz quad-core Qualcomm Snapdragon 600 processor (depending on country), 2GB of RAM, a 5-inch 1920x1080 Full HD AMOLED display at 441 ppi, a 13-megapixel rear-facing camera with 1080p HD video, a 2-megapixel front facing camera, internal storage between 16 and 64GB, an SD card slot that can accommodate an additional 64GB, a polycarbonate body, Smart Pause and floating touch tech and runs Android 4.2.2 Jelly Bean.
