Galaxy Grand I9082 - very slow when internet enabled.

[AC Question]

Whenever i enable my "Mobile data" or "WIFI" my mobile (Samsung Galaxy Grand I9082 ) becomes too slow, every task from then on takes atleast 10 to 15 secs to complete, like opening the browser.. enabling the keyboard.. typing the text.. attending to calls.. everything is too slow..

Things i tried :
1 . Rebooted the mobile and tried - issue extists.
2 . Uninstalled all the apps i installed one by one and checked - issue extists.
3 . Done a complete factory reset. - issue extists. :-(

I appreciate if anybody can help me on this issue.

Thanks,
Sathish.K

Welcome to Android Central! Did this just start happening, or has it always been like this? Is the phone brand new, or have you had it for a while? Did you buy it new or used? Is it rooted or unrooted? Do you have Bluetooth on? If so, try turning it off, in case it might be causing interference.

What happens if you turn Auto-Sync off? Go to Settings>Data Usage, tap Menu, then uncheck Auto-Sync Data.
