How to Install LineageOS 14.1 on Galaxy A7 2017

In the past couple of weeks, LinegaeOS has made its way to a number of Android devices and brought a lot of features. After roaming out for quite a while, LineageOS has finally found a way to Samsung Galaxy A7. Lineage OS is a successor to CyanogenMod and is equally popular as the latter was, back in the old days. While the ROM took some time before making its way to Galaxy A7, considering the stability and features, the wait appears worthwhile. For Galaxy A7 2017, LineageOS 14.1 has been released despite that some of the devices have already got LineageOS 15.1. Here, for your ease, we have provided the required links to the official LineageOS site so that you can download the ROM file as well as the instructions to help you install LineageOS 14.1 on Galaxy A7 2017.

The LineageOS 14.1 build has been released officially a couple of days ago and if you find LineageOS 15.1 for Galaxy A7, note that those are unofficial builds and aren’t as stable as the one being discussed here. Also, the fact that Galaxy A7 has received a fairly consistent security patch indicates that the device will get LineageOS 15.1, eventually. Now that Lineage OS is out, you can install it on your Galaxy A7 device and make the most out of it. A custom ROM is always a good way to extend the boundaries of your Android device, both in term of performance and features. Since LineageOS has been around for quite some time now, it has improved over the course of time and is very stable.
