You Might Not Get Android 5.1.1
It's important to know that your device might not ever get the Android 5.1.1 update.
Samsung is often selective about which devices get which Android update. Just because one Galaxy S5 in the U.S. got Android 5.1.1 doesn't mean that every single Galaxy S5 in the United States will get Android 5.1.1. Samsung and its smaller carriers might choose to hold off until the next big release.
We wouldn't read too much into Sprint's decision to upgrade its Galaxy S5 and Galaxy Note 4 with smaller non-Android 5.1.1 bug fix updates. That said, if you own one of those devices or another Android 5.1.1 eligible phone, we'd remain cautious until the update starts rolling out.
With an Android M release supposedly close, we could see some devices and carriers move directly to Android M.
