If a device is popular enough, it will always be backed up by the developer community. This is how it has always been in the Android market and the Nexus 5 is a clear example of this. This device is being backed up by developers to gain entry into the latest update.
The vast majority were disappointed when Google announced that it will not be bringing the latest Android update, Nougat, to the Nexus 5.
But maybe it would have been better to whine about the terminated monthly updates for the Nexus 5, instead.
It will definitely be difficult to keep the Nexus 5 virus-free without the help of Google’s latest security updates. However, it will not be that difficult to bring the latest Android versions into the device.
Even if you’re not one that is familiar with custom ROMs, there are a lot of tutorials on the web that could assist you. All you have to do is to master that and you’ll soon be seeing the Android 7.0 or even the 7.1 on your Nexus 5. Plus, there are even options to select from, thanks to the increasing number of third-party developers around.
Aside from the Hammerhead based CM14.1 custom ROM build, you could opt for the CAF version, as well. Many people had argued that the latter is the better option because of its updated drivers and superior audio quality, however, it is the Hammerhead build that comes with better alt kernel availability.
Well, each of these custom ROMs comes with their own sets of pros and cons, so be sure to do your research prior to attempting the flash.
