Uninstall your Facebook app and just use a browser for Facebook. This one change ended all my locking and speed lags. Their invasive app is absolute garbage.

Look at the KeyOne thread about making it faster. There are three settings that can be changed and once that's done, there is an incredible and obvious speed increase. I use the Dtek60 and mine is now blazingly fast!

Settings, About phone, then keep tapping the bottom build number until you've enabled developer mode, then change the three animation delays to 0.5 and you will be shocked.

It worked for me. Apps respond much faster. Thanks for the tip! ;-)

Sometimes the device lock when I open some app, but in my point of view, this problem is android.
