Recently I came to know about some phones which are based on MIUI and CyanogenMod. I want to know if the meaning behind it is they will get lifetime updates from MIUI and CyanogenMod or something else?
- CyanogenMod OS is a custom ROM derived from Google's Android OS. It is available for large number of devices and delivers updates as nightlies, release candidates, betas, snapshots etc. Frequency of updates depends on the type of ROM flashed onto the device.
- MIUI (Mi User Interface) is also a custom ROM which is based on both Google's Android and CyanogenMod but has a home-cooked and customized interface developed by a Chinese firm Xiaomi Tech. It highly resembles Apple's iOS interface. MIUI is available for some flagship phones from popular brands.
All the devices running on CyanogenMod and MIUI gets updates very frequently than others. Updates occur over-the-air (FOTA). As a bottom line they are used as stock firmware replacements.
MIUI is made by the Xiaomi company. It's the skin, based on Android, they use on their devices like the Redmi 2. Xiaomi provides the updates to these devices. Not that officially they are only released in the eastern market, but I've read some news that they are expanding to the American and European market as well.
Cyanogenmod is the first, popular custom version of Android provided by Team Cyanogenmod. It's still actively developed and being released for a serious amount of devices, but his is unoffical for every device except the OnePlus One, but that deal is also over now. See their website for more info
MIUI is a highly customized UI that almost acts as a new OS giving you access to all the features of the latest android and many of its own features like themes and lockscreen activated music player and all with the same buttery smooth performance of early iOS versions. It is no surprise in only 5 years it is the fifth largest smartphone company and the largest in its home market.
Cyanogenmod is the next best thing a rom of stock android with all the limiters removed. It is very customizable within the limits of the android version it uses. Performs just as well as any android device with a few glitches since it is much more feature filled than stock. Some of its best features are 5x5 pattern lock and nightly updates.
