But keep in mind, you will be limited to using the Samsung Galaxy S4 with GSM carriers only. So in the U.S., that means AT&T, T-Mobile, or any prepaid carrier that uses either of these networks. For the vast majority of consumers in the U.S., having a locked cell phone doesn't really affect them much, because they don't plan on switching wireless carriers anyway and they have no plans on using their devices internationally. If that's the case for you, then getting an unlocked device isn't a major advantage.
What's it mean to have a phone that is "bootloader" unlocked and supports the "pure" Google Android experience? A device that is dark botanic iphone case "bootloader" unlocked means that you can put any custom ROM or version of Android software on your device that you like, This is not true of Android devices sold through wireless operators, Not only do those devices have the carrier software lock on them so they can't be used on other networks, but they also lock the device so that updates can only be added to the phone when they're issued by the carrier..
These devices can be "jailbroken," which will allow users to update it with any software they like. But doing this may void the device warranty. The Nexus version of the Galaxy S4 offers the "pure" Google Android experience, and it does not have this restriction. As a result, it means that the device will be able to get any software update that Google issues as soon as it's available. And the device warranty won't be affected. In other words, people with the Nexus version of the Galaxy S4 will not have to wait when the next version of Android, 5.0 Key Lime Pie, is released. Meanwhile, wireless subscribers who buy a Galaxy S4 from a carrier must wait until Samsung and the wireless carriers have tested the new version of Android before they push the update to customers. The process often takes several months. And some Android devices never get the update.
Why are the updates so slow to roll out on the devices available through the carriers, and not for Google Nexus phones sporting the "pure" dark botanic iphone case Android software? The main reason is that Samsung and other device makers like HTC have created their own software "skins" that are layered on top of whatever version of Google Android is running on the device, In the case of the Samsung Galaxy S4, it uses Samsung's TouchWiz software, What this means is that when you buy a Galaxy S4 from a carrier, whether it's AT&T, Verizon, T-Mobile, or Sprint, it will run the current version of Android 4.2.2 Jelly Bean, But it will also have Samsung's TouchWiz user interface on top..
TouchWiz not only changes the user experience of the device from what you'd see if only Android 4.2.2 was running on the device. TouchWiz also adds lots of new functionality. Some of the Samsung-only features are gratuitous, and you likely wouldn't miss them if you didn't have them anyway. But some are pretty useful. For example, Air View allows you to hover your finger over something and it will display information. The Smart Screen functions are also pretty cool. It keeps the screen on as long as it can detect your eyes looking at it. And you can even scroll down the screen by moving your eyes. Of course, these TouchWiz features only work within Samsung's own applications, such as the device browser. This means that if you loaded a mobile Chrome browser on your device, it wouldn't work the same way.
