If your phone has limited memory storage and you regularly use Facebook and Twitter, installing lightweight versions of these apps could help to speed up your phone.
Facebook Lite, for example, works just as well as the full version yet uses a fraction of the resources of the full app. The Facebook Lite app is small and allows you to save space on your phone and use Facebook in 2G conditions. To use it:
– Go to play.google.com
– Locate the app, and install it.
– n.b. Google also has lightweight versions of YouTube
Also, Twitter has a lightweight client which you can find at mobile.twitter.com.
