Samsung Galaxy S4
The Samsung Galaxy S4 is going to be replaced, likely in March, but until then it remains one of the top options on T-Mobile's network. Those who can't wait and are in need of a smartphone this month will find that the Galaxy S4 remains one of the best smartphones on the market almost a year after its release.
This is due to the high quality hardware that Samsung has put on board in addition to the solid software support that Samsung offers its flagship smartphones. The Galaxy S4 is due to receive Android 4.4 KitKat in the near future and should see at least one more update after that.
