Regardless of what device you currently own, if you are not that keen on the current operating system or skin installed, then thanks to the third-party aftermarket, you can pretty much put whatever you want on your device. In short, this is one of the major benefits of the android operating system. As a result, those in the ROM and alternative OS communities will be well aware of the abundance of ROMs that are now available. Not to mention, the other benefit of using a third party ROM is that you are likely to receive better support and more often updates for older devices than on major manufacturer releases.
Of course, CyanogenMod is probably the most commonly touted alternative ROM that you will hear about most often. That said, they are by far, not the only ones available. In fact, another very well-known ROM which goes by the name of Paranoid Android has just seen its next major release becoming public. When it comes to Lollipop, Paranoid Android have not been the quickest at getting their update out the door and they do acknowledge this in their various announcements. Not to mention part of this delay is probably due to their OnePlus involvement of late. But that said, they do come. Their first major Lollipop was released in an Alpha form back in February. Well. following on, today, the Paranoid Android team have announced that the next stage in their Lollipop journey, Android 5.1 is now available.
The latest release is for essentially only for Nexus devices and unfortunately, not for the entire Nexus range as some are excluded due to the team not having the devices in-hand to test the builds on. In terms of the updates, features on offer include the likes of Theme Engine and Quick Settings. Not to mention if you own a Nexus 6, then you can take advantage of WiFi calling (if on T-Mobile) and VoLTE (if on Verizon or T-Mobile). In terms of what devices are good to install the builds now, builds are available for the Nexus 6 (shamu), Nexus 5 (hammerhead), Nexus 4 (mako), Nexus 9 (flounder), Nexus 7 2013 WiFi (flo) and Nexus 7 2012 WiFi (grouper).
