The use of curved displays is increasing rapidly in modern smartphones. Normal screen protectors are not always effective on this type of display. So in many cases UV glue-based tempered glass or screen guards are used, which adhere well to the curved part of the screen and provide added protection.

However, there is an important risk when using this UV glue. If the glue accidentally gets into the phone’s earpiece, speaker, power button, volume key or any other sensitive part, it can damage them. In some cases even permanent problems can occur.

This is where the little stickers on the phone box come in handy. Important openings of the phone are covered with this sticker before the screen guard is attached. As a result, UV glue cannot penetrate and sensitive parts are protected.

The method of using the stickers is also quite simple. Before attaching the screen protector, stickers should be applied around the earpiece, charging port or buttons. Then using glue to install the screen guard reduces the risk of the glue getting inside the phone.

But most of the users are not aware about the importance of these stickers. As a result, he threw them away after opening the box of the new phone. But this little tool can save the phone from expensive repair hassles.

So later after buying a new smartphone one should take a good look at each and every item in the box. Sometimes a seemingly insignificant little sticker can go a long way in ensuring the security of your beloved smartphone.
