OnePlus 6 has a great fan base throughout the globe, probably because it is OnePlus’ last phone with a headphone jack. The OxygenOS is great but some of you who look for more customization would be on the lookout for other OS. There is nothing better and stable than the LineageOS 16 and after Essential Phone, Xiaomi Mi Mix 2 and Xiaomi Mi 6, OnePlus 6 has been added to the list as well.

It is the biggest custom ROM and has more than 1.6 million installations across the globe. The phone was never really supported by this OS before this moment but it makes sense as the OxygenOS is updated on a regular basis and is very close to Android. If you are OnePlus 6 owner, then this is great news for you.
