For those who feel like their android phone is a little stale OR would like to improve performance / increase customizability on their android phone - try a new launcher (search "launcher" on google play) - tons available!
Popular ones include:
Google Now ("Stock" android launcher - useful for those that have phones from companies with skinned android launchers, like Samsung, LG)
and my favourite - Smart Launcher (incredibly light and fast. Very different experience than the stock launcher).
