Back of my iPhone is loose?

The back of my iPhone 4S is loose and I was wondering if there was a way to tighten it before it gets worse? It's not that bad but it's noticeable.

Go to nearest phone shop and get replacement, or get a good phone cover to secure it.

There are 2 screws on the bottom of your iphone, you need to have a special star headed screwdriver which you can buy online quite cheap. Tighten the two screws and the back shouldn't move.

I fixed mine with superglue, it will never bother me ever again.

You can buy replacement backs to your iPhone. You can also tighten it with the screws on the bottom of the iPhone.
