Few days ago I buy the wonderful lg nexus 5 that was awesome. The Nexus 5 offers the best bang for your buck, with amazing specs and the latest OS for a very reasonable price.
With a new Nexus 5 device on the horizon, its likely that the current Nexus 5 could see some more price drops in the near future, which could make it even better value for money. The Nexus 5 was able to hold its own with the top devices of 2013, including the iPhone 5S, Samsung Galaxy S4, HTC One, and Sony Xperia Z1, but hold it up against the flagships of 2015 and the Nexus 5 is left lagging behind.
The Nexus 5 smartphone brought Android 4.4 KitKat with it and has been amazing picture quality.
