Why won't my device connect to 4g?

[Chrisjen]

My phone is suppose to be 4G and I've never had an issue but within the last few days it only says 3G and is running very slow. Help...

Try this:

Turn off phone

Remove the battery and SIM card, wait a minute and reinsert both.

Hold down the Home and Volume Up keys

Press and hold the Power button while still holding the other keys.

As soon as you see the Samsung logo, release all keys/buttons.

Press on the Volume Down to scroll down to Wipe Cache Partition.

Press the Power button to select it.

Press the Volume down button to highlight "Yes" and press the Power Button to select it.

Wait for a few minutes for the phone to clear the data.

Then press the Power button to select reboot system now.

Wait for your phone to reboot.
