An alleged (that being the key word here) internal test on the Samsung Galaxy S4, performed by Samsung, revealed that the company thinks the device is good but not quite the best.
The report acknowledges that the device is good, but doubts that “this model can revolutionize the market”. Still the study concludes that Samsung is conquering the smartphone market and leading among manufacturers of Android devices.
Reportedly Samsung tested other high-end smartphones (no word which) in order to compare them to the Galaxy S4. But this is a known practice by R&D departments in big companies and shouldn’t come as a surprise.
Still the rumored internal test could prove to be nothing more than a hoax so take it with a pinch of salt.
