The thing about ROMs like CyanogenMod is that it is largely maintained by the Android community, versus iOS or Android where it has the backing of companies that created it. This also means that sometimes support might not necessarily be so readily available across all devices, at least until now.
CyanogenMod has recently announced that they will be expanding the list of supported devices for the ROM. This means that if your device was not supported previously, there is a good chance that it will be supported now. For example they have announced that they are now working with Huawei’s team which in turn has led to more support for their devices.
This includes handsets like the Honor 4 and Honor 4x, Ascend Mate 2, Snapto, and so on. They have also announced support for the Moto E and Moto G’s 2015 variants, and have also thrown in their support for Xiaomi and devices like the Xiaomi Mi3w and the Mi4. There are also other brands you might not have heard of like Smartfren and the recently announced WileyFox.
There will be additional support for Oppo, Samsung, HTC, and LG’s other devices, so if you were feeling a little left out from before, hopefully now you will be able to enjoy the CyanogenMod ROM.
