Past  week,one of my friends assisted me for fixing an error in his phone.
The problem was about, he wasn’t able to connect to Playstore or Gmail on his android phone.

Also,There was a pop up saying ‘‘connection problem,try later ‘’.
But after sometime I figured out the solution. And I’m really glad to share it. 

can’t connect to google,or cant sign in’.

Why is it so?

Well, there are few reasons for this trouble. First reason would be because you might have removed Google Play Service for some reason.

Second reason would be because your Google Play Service might be outdated.  Try upgrading it.

And If you’re are having any system cleaner, make sure Play Service is in the white list itself.
