The Samsung Galaxy A9 Pro is apparently nearing official status if benchmark listings are any indication. After it was spotted on GFXBench earlier this month, the upgraded variant of Samsung's 6-incher has now made its way to AnTuTu, confirming the key upgrades over the vanilla A9 (2016).
For one, the 13MP primary camera gets a bump to 16MP, so the A9 Pro won't have the same sensor as the rest of the A (2016) lineup. You'd also be getting higher-res selfies than on the regular A9 - 8MP vs. 5MP. Befitting the Pro moniker, RAM is also a gig more, at 4GB.
The rest is all the same as the Galaxy A9, meaning a Snapdragon 652 chipset and 32GB of storage. The older GFXBench listing put screen size at 5.5 inches, but we all know how benchmarks can get that particular bit wrong. We'd say that 6 inches is the safe bet here, even if AnTuTu stays mum on the matter.
That's not 100% accurate, it even says it at the bottom of that page. It isn't official so we'll know for sure then, but we can't know for sure now
Samsung Galaxy A9 Plus Pro would have 6.5".
