Anyone know how to uncheck the use network provider time.
Its checked but shadowed in grey. I can change use network provider time zone.
But it still won't let me change the time to what ever i desire. I like putting my tome 5 minutes ahead, but for the love of my life i just can't seem to be able to change it. My premia is rooted if it helps any
