A new rumor says that Sony will use Samsung's EXYNOS proccessors in their new high-end smartphone.
Since Samsung uses their own EXYNOS processors in their own smartphones everything is very smooth. The biggest problem of EXYNOS at the moment is the source files by Samsung. Samsung isn't giving the source files of the EXYNOS processors that easy. Many developers aren't happy with Samsung. Some developers even switched to brands like Sony and HTC. Let's hope Samsung can make the developers for all EXYNOS products happy.
Most developers are still waiting for the good source files to make their own CUSTOM roms better and of course faster.
