I am a Korean Android Development Beginner.
Today, I would like to introduce my app.
It is called "Google Service Network Error Fixer". ("G.S.N.E.F" for short)
It needs root access!
This app fixes some Google Service errors caused by network problems. (Not all)
I'll work hard to make this app so it can fix more errors.^^
You can find it in the Play Store if you search "G.S.N.E.F".
(Sorry I couldn't link it. I didn't write 10posts yet.)
