Apps are not running

[ash198923]

I have got samsung G720N0 and am facing a strange problems. No any apps like facebook, messenger, and youtube are running. They ask me to connect to the network. But at the same time I can download all these apps in play store. I have even updated google play services but no any good news. Can anyone help me fix this?
