Android Central Question
It shows network boosters at times and at times it doesn't, how can i repair it because my local technicians cant make it
If im not wrong at the time Samsung had download booster where it take mobile data/wifi same time to download files faster or apps.Welcome to Android Central! You don't see it in the Settings>About Phone menu? Did you get this phone directly from Samsung or a reputable retailer, or did you get it from some random seller? If the latter, and there's no serial number displayed in the About Phone menu, then there's a good chance it's a knockoff.
What do you mean by "network boosters"?

That i have no clue unless they trying mention 2 different issues they haveBut I wonder what that would have to do with losing the serial number?
