It appears as though Samsung has begun the testing phase for its successor to the Galaxy S III, albeit with lower-end specs. The benchmark outs the device as wielding a WVGA display and dual-core 1.2GHz processor. Of course the rumored Galaxy S IV powerhouse won’t be sporting those measly specifications, but before you rule this leak out as a fake, keep in mind that Samsung consistently tests pre-production firmware on devices with lower specs than the model that will actually see a release.
For example, last year we encountered several early benchmarks of the Galaxy S III with these very same hardware components (which began showing up in December). This allows Samsung to thoroughly test preliminary software and make inherent changes on a test unit, despite not having the actual components that will be present in the GS4.
