For those who have the Nexus 5 and don’t mind taking the HTC Sense 6 UI for a spin, you can head on over to the XDA forums to find out more and to download the ROM. However we should note that the Sense 6 ROM for the Nexus 5 is currently in its alpha stages meaning that there not all of its functions are working.
At the moment according to the developer who ported it, GalaxyUser, the functions that are working at the moment includes the touchscreen, SIM card detection, SMS and phone calls, WiFi, SD card, vibration, Bluetooth, and light, orientation, and proximity sensors. Of course given its alpha nature there are also bound to be plenty of bugs that needs fixing, so if you wanted to use it as your daily driver, it’s probably not the best idea.
In the meantime it seems that while the Nexus 5 could potentially be enjoying the HTC Sense 6 UI, HTC’s own products like the HTC One from 2013 have yet to receive the update which is currently scheduled for a late-May release.
