Most people don’t replace a computer or a laptop anywhere near as often as they replace their phones. The reason for this is largely due to the fact that these companies that sell us devices do things to entice us to update. The main way these carrier stores remind you to update is by stopping the roll out of software updates. True, an older operating system on a computer can stop being updated too, but that can take as long as fifteen years for that to happen. Something that was built around the early 2,000’s and is running Windows XP might no longer be supported by Microsoft. With our smartphones that support comes to an abrupt end much sooner — often around three years or even less.

A custom ROM can help out here.  By installing something like the CyanogenMod 12.1 Nightlies ROM on your Huawei Honor 4X smartphone, you can update to versions of Android that you couldn’t get from your phone carriers. For example, the CyanogenMod 12.1 is based on Android 5.1 Lollipop — an update that never ended up coming to you because they want you to buy a new phone.
