When you are shopping for a new smartphone screen protector, start by narrowing the search by compatibility. A cell phone screen protector must fit well to be effective and comfortable to use. Dimension, placement of your phone’s speaker, mic and any buttons and whether the screen has a curved edge all matter. Whether you are choosing among iPhone screen protectors or Android screen protectors, remember that you must also check for compatibility with your specific model.

Once you have narrowed the options to the ones that will work with your phone, your biggest choice will be the material of the screen protector. PET screen protectors provide affordable and lightweight screen protection. TPU takes protection up a notch, and it can self-heal from certain kinds of damage and bend with curved-edge screens. It does, however, have a rubbery feel.

You will get better scratch and drop protection if you go with a tempered glass screen protector. They can also offer additional features, like privacy and anti-glare.

Just like a cell phone case, a screen protector is an investment in your phone’s long-term performance. It will offer a barrier against damage from scratches, drops spills and more. That is why it is listed alongside the phone case as one of the must-have accessories for your phone.

Additionally, some screen protectors offer extra benefits. For instance, an anti-glare screen protector can help you see the image on your screen when you’re out in the bright sun trying to take a picture or looking up directions. And a privacy screen protector blocks the view of your screen from side angles, so people sitting next to you will not be able to see messages you are typing or reading.

There are a number of other important cell phone accessories that will make your life easier or more secure as well, such as a cell phone mount for the car, a Bluetooth headset and extra charging cables. If you often drive to out-of-the-way places, you might benefit from a cell phone signal booster. And if you have a tablet, you should consider investing in a tablet screen protector.
