Can not uninstall facebook I have a brand new Qmobile 400 dual sim tab with jelly bean android 4.2.2 version. 
Downloaded facebook from play store but now unable to uninstall it. The message say" delete all the updates on this device" but not the app itself. How do I uninstall it???
You can install Link2SD, an app that allows you to uninstall any and all applications, system included.
