According to the benchmarks, the Sony Xperia XZ2 will be powered by a Qualcomm Snapdragon 845 chipset and will be accompanied by as much as 4GB of RAM. It also appears to pack an 18:9 display ratio with a 2160×1080 resolution, which seems to have potentially dispelled the rumors of a 4K display. It also looks like it will run on Android 8.0 Oreo.
That being said, we should point out that the phone being benchmarked does not mention the Xperia XZ2 specifically, but rather it has the model number Sony H8266. However given that the phone in question will be powered by the Snapdragon 845, it also means that it will be a flagship device which sounds like it could be the Xperia XZ2.
In any case Sony will probably have more details to share at MWC 2018, so remember to check back with us in the coming weeks to find out more.
