While it's powered by the octa-core Qualcomm Snapdragon 652 processor that's found inside the regular Galaxy A9, the Galaxy A9 Pro comes with 4 GB of RAM (instead of just 3 GB), and runs Android 6.0.1 Marshmallow out of the box (whereas the Galaxy A9 still runs Android 5.1 Lollipop). According to China's Telecommunication Equipment Certification Center (aka TENAA), the new Samsung smartphone also has an 8 MP front-facing camera and a 16 MP rear one - both representing upgrades from the 5 MP and 13 MP cameras of the older model. The rest of the features seem to be similar to those of the regular A9, including a 6-inch Super AMOLED display with 1080 x 1920 pixels, LTE connectivity, 32 GB of internal memory, and microSD card support.
We don't know where and when the Galaxy A9 Pro will be released, though it's probably safe to assume that it's going to hit the market in China first (just like the regular Galaxy A9). Perhaps Samsung wants to launch this A9 Pro in more regions than the regular handset (maybe even in the US)? We'll let you know when we find out.
