Launched three years ago, the Galaxy S5 was one of the most unfortunate Samsung smartphone ever produced, which performed very badly in the market. If you still have that device from years back, there is a good news for you. The new Oreo update via a custom ROM (LineageOS 15) is now available for the smartphone.

The Oreo update LineageOS 15 custom ROM is based on Android’s latest OS Oreo. This ROM is available for a number of Android devices, including some old ones too. But there are only a handful of Samsung devices on which this custom ROM can be flashed. This is mainly because Samsung is not sharing kernel sources of most of their devices with the developers. And without kernel source, developers are unable to bring Oreo update for most of the Samsung devices. Samsung themselves hasn’t released any plans about Android Oreo update for the Galaxy smartphones. But we are pretty sure that Android Oreo update for the Galaxy S8 will start rolling out very soon, as it is said to be under testing. Till then, if you have a Galaxy S5 somewhere around you, you can enjoy LineageOS15 ROM on it.

LineageOS 15 ROM has released just a few days ago. So, it is still untested, that means it may contain some bugs. And that’s why we won’t recommend it for daily use. The better and stable version of LineageOS15 ROM is expected to released in the coming months. So till then, you can enjoy this version before other Android users.
