Does anybody here have a Samsung Galaxy 4 and if so, any helpful tips or things for me to know, do or not do?

Only one, ‘cause I’m not a big fan of that phone. Get a good screen protector if you haven’t already done so.

In google, do a search for “galaxy s 4 xda”

The first links should show you the different versions of the phone (ATT, T-mobile, etc.). Choose your phone.

XDA has tons of useful information about nearly every phone out there. Plus you can make an account and ask questions about your phone to other people who actually own the same phone as you do.

I have the GS3. I can’t imagine there’s that much of a difference between the two. The only thing I can think of is be sure you read all of the app permissions when downloading apps from the Play Store. Some of the apps don’t necessarily need all those permissions such as location if it’s just a game.

Camera Outstanding.Easy to use like mini computer.Install what ever you want to install in your S4.
