While it does have a lot of potential and is definitely not a slouch when it comes to performance, Samsung has yet to figure out a way to get their Exynos chipset to play nicely with LTE-A networks along with the lack of 4K video capture capabilities, which is what their competition, the Qualcomm Snapdragon 800, is able to do. Granted not everyone needs 4K video capture, but presumably LTE-A support is a key feature that many would like to have and is the reason why some believe it is the lack of support for those features that is causing the loss of market share in the AP market. It has been rumored that 2014’s Galaxy S5 will feature a new Exynos 6 chipset that will hopefully address those issues.
