CyanogenMod is the best and most popular custom Android ROM in market which also been main reason behind the massive success of OnePlus One the the very first device of Chinese mobile device startup OnePlus. OnePlus released its second device OnePlus 2 with own custom ROM called Oxygen OS as a default OS. OxygenOS a buggy and very unstable OS I’ve ever used which screwed the hardware rich and potentially unbeatable device like OnePlus 2.
OnePlus One predecessor of OnePlus 2 is still better than OnePlus 2 on performance basis which is just because the stable and bug free OS CyanogenMod. OnePlus has released 4-5 OTA updates since it started selling OnePlus 2 but its still to buggy and unstable. With every OTA updates if they are fixing suppose 2-3 issues then the same OTA raising few more issues sudden after installing the OTA updates. I highly doubt that they have any kind of testing team or they are even doing any kind of testing before releasing OTA updates.
If you are too much frustrated with OxygenOS and ready to compromise for few features then you can install CyanogenMod on OnePlus 2. There isn’t any official CyanogenMod ROM released yet for OnePlus 2 but there is an unofficial ROM which you can try for now.
