So far, users who’ve flashed their Zenfone 2 devices with the new CyanogenMod ROM have been reporting very positive experiences with the operating system, claiming that it improves the usability of Android a lot and also adds some nice performance boosts and tweaks.
We don’t know if the phone will keep getting access to new Android versions in the form of custom ROMs, but that probably depends on how its popularity will change in the future. If it remains a device owned and used by many people, then the custom ROM community will keep making new releases as well.
There are also various benefits to using a custom Android ROM on a device like the Zenfone 2 – it can help get even more out of the phone’s hardware as it makes better use of the available processing power.
Many users even use custom ROMs in general, despite having access to equivalent official Android versions. It often turns out that CyanogenMod ROMs, as well as other custom ROMs, tend to run much faster and smoother than the default Android for any given device, with the exception of newer handhelds which are often designed with even more optimizations that can make full use of the power of Android and what it offers behind the scenes.
