Multiple sources are reporting that the Samsung Galaxy S5 is now being tested for Android Marshmallow 6.0 in several markets. US carriers have already leaked testing the S5 as well. However, release to the general public for the Galaxy S6 has remained slow if not halted. With the S5 sharing more of a design similarity to the S7 rather than the S6, could we be seeing Samsung's first basically orphaned flagship phone? If so, why not release the unlock codes and let the aftermarket support it?
