Sprint's Samsung Galaxy S5 is updated to Android 4.4.47
Since the update is being sent out on a staggered basis, don't start planning your demise if the update doesn't hit your Galaxy S5 today. It should be coming at any time. Believe it or not, Verizon's Samsung Galaxy S5 received its Android 4.4.4 update back in September. If you're new to the exciting world of mobile devices, this irony probably means nothing to you. But if mobile is your life, you'll know that Verizon is usually obsessive compulsive when it comes to testing updates and is usually dead last among the four major U.S. carriers when it comes to pushing out updates.
When you are ready to download and install Android 4.4.4 on your Sprint branded Samsung Galaxy S5, you should make sure that you are connected to a stable Wi-Fi network first, so as to preserve your precious data. And recharge your battery to at least 50% charged. You wouldn't want to end up in limbo if your handset dies in the middle of the updating process.
