Off late Samsung has seemingly accelerated their process of development of their next flagship. In fact it's the first rumour regarding their upcoming Galaxy S7 arose a few months back. But it seems that now the rumours are taking pace!
A few months back Gizbot had revealed that the Korean giant was testing out the latest gen Snapdragon 820 SoC in their upcoming flagship S7 - codenamed the ‘Jungfrau'. Rather Samsung wasn't just testing the Snapdragon SoC for their devices. The bunch of S7 was also being tested with the company own Exynos SoC on the inside.
Samsung had dumped the Qualcomm in their last iteration of their flagship device, namely Galaxy S6. Hence it was quite natural that Samsung would be rather skeptical on using the Snapdragon SoC on the S7. In fact a new report by a Korean publication state that the company was rather critical with their S7's running the Snapdragon 820 - after all they were precarious regarding the heating issues of the SoC, keeping SD810 in mind.
However Samsung is reported to have finally given their final nod regarding the use of that SoC in some operating markets. This report whilst symbolizing the comeback of the Qualcomm in a Samsung flagship, also tell us that the SD820 is not as bad as its predecessor. Otherwise it would have been tough to get a green light from the company!
