Vivo is preparing to launch the X300, X300 Pro, and possibly X300 Pro Mini phones during the fourth quarter of this year, i.e. between October and December. Prior to that, the seemingly regular X300 appeared on the Geekbench database.

The test confirmed that the phone will be powered by the new Dimensity 9500 processor from MediaTek, which is expected to be announced next September. The test version (model number V2509A) came with 16GB of RAM and Android 16 operating system, which is the version with which the phone is expected to be officially launched.
