Nexus 5 is one of the best Android phone you can buy right now. What I like about Nexus phones is that along with some nice specifications, the phones come with sleek and standard design which you can really show off.
Nexus 5 was the first phone to have Android 4.4, Kitkat. If I will asked to choose between iPhone and any High-end Android phone, the only reason I will be choosing the Android phone is because I love customizing and as an Open Source project, Android gives the users every possible customization option.
Rooting and Unlocking your Nexus 5 will allow you to install third-party ROMs on your phone which can improve interface and functionality of your phone. If you don't want to Install ROMs, you can still flash Mods like Icon Themer.
Non-rooted users can install third-party launchers from Google Play Store. They can also use icon packs, themes and widgets. Apps like UCCW, Themer can help you in customizing your phone. In this post, I have gathered some of the nicest Nexus 5 phone customizations from different Nexus 5 users of this Google+ community.
