Quick reminder, tip, heads-up and whatever else you need it to be: inserting stuff wrong could cause it to break. That’s true for almost everything, and the newest thing it’s true for is your Samsung Galaxy Note 5 .

Consider yourself warned that inserting your S-Pen into your Samsung Galaxy Note 5 backwards could cause the phone to break. Make sure the tip of the S-Pen that you would use to write on the display with is going in head first, meaning the clickable top will be the last visible part of the S-Pen before it’s fully inserted.

Doing this wrong won’t totally doom your phone, mind you, but it could cause your S-Pen to get stuck in there, and there’s a chance S-Pen auto-detection will kick the can, too.

To be fair to Samsung, this warning is in the user manual that no one ever reads:

It’s also just plain common sense to make sure you place things where they’re supposed to go in correct fashion. If yours breaks as a result of carelessness, well, fingers crossed Samsung or your carrier will hook you up with a free repair. Otherwise, let it serve as a very valuable (and expensive) lesson learned.
