LG Nexus 5 beats Nexus 4 with notable hardware and software upgrades, but the previous generation Nexus smartphone is still worth keeping for a few more years. Here are five reasons why you shouldn't sell, trade or throw away the Nexus 4 if you are not that desperate.

Android 4.4 KitKat

Right now, Android 4.4 is exclusive to the Nexus 5, but Google will soon push firmware updates to other Nexus devices including the Nexus 4. Owners of the Nexus 4 can expect use of new features such as "Ok Google", smoother UI, accurate touch response, improved lock screen and many more.

Full Google Apps Integration

Android 4.4 KitKat comes with various changes to applications and system performance. Google Drive, Keep and QuickOffice become native apps, while Hangouts can function as SMS/MMS client in addition to social connection with Google+ circle.

Custom ROMs Allowed

Google allows full customisation of Android devices via root access and then flashing of customised ROMs made by third-party developers. Nexus 4 owners may use custom ROM to get additional tweaks and features from other developers running older Android versions or newer ones.

It is expected that Google will make Android 4.4 KitKat public before 2013 ends that will then enable custom ROM makers to create their firmware versions with matching add-ons. Get Android 4.4 KitKat from popular custom ROMs such as CyanogenMod, Slim ROMs, Paranoid Android and Omega.

Holiday Gift

If you are thinking of purchasing the new Nexus 5, you can still recycle the Nexus 4 and give it as a holiday gift this Christmas to someone you care about who isn't particular with technology. The Nexus 4 features 4.7 inches of In-Plane Switching (IPS) display screen with Gorilla Glass 2, 8 MP rear camera, 1.5 GHz quad-core Snapdragon processor and 2 GB of RAM for app multi-tasking.

Extended Life Cycle

Even if you keep it or gave it to someone as a gift, expect extended life cycle with the Nexus 4 as Android 4.4 KitKat brings lightweight system and optimisation across older devices. The LG Nexus 4 may remain to get firmware support up to the next Android version after 4.4 which is something to brag about compared with other devices.

The LG Nexus 4 isn't near with the quality of Galaxy S4 and Sony Xperia Z but costs less in comparison. Its current technology remains a good entry level for newbie Android users as it supports various features, functionality and applications than older devices.
