Lenovo A7000 CyanogenMod 13 is powered by Android Marshmallow 6.0 which is an advanced custom ROM for smartphones that have many customizations and modifications options for the user, it even consists of custom themes and other premium features.
We believe you might have liked our previous custom ROM Androium 7 which is based on Marshmallow 6.0 and has pure AOSP experience, it is totally stable and ported by the same developer HDHR.
The CyanogenMod 13 for Lenovo A7000 is also a stable custom ROM with very few bugs that we can ignore such as the blue-tooth cannot connect to external blue-tooth headphones/speakers but the normal blue-tooth is working absolutely fine to transfer files to another blue-tooth enabled device, another bug which is present in the ROM is 720p 60 fps video lag on youtube which we believe is not a major issue and this custom ROM can be used for regular use, apart from this all the features are working flawlessly and without any glitch.
If you are a Marshmallow lover then this ROM is perfect for you but if you want to put your hands on Android Oreo-based custom ROM then you can follow this article Lineage OS 15.1 which is the successor of CyanogenMod. Lineage OS 15.1 has minor bugs like proximity sensor issue but it also has a patch for it which you can flash along with the ROM. Apart from that, you can even try Nitrogen OS or OmniROM based on Android Oreo 8.1
