They do not last, they make scrolling through the screen unpleasant, and writing on the screen with the S-Pen / Stylus leaves a mark. Putting on a plastic screen protector isn’t easy either. You have to wipe the phone, spray the screen protector, and use an unreliable squeegee provided to put the difficult piece of plastic on the phone. On top of it all, a plastic screen protector only protects the screen from smudges. Luckily, the Tempered Glass changes all of that.The YourDeal 0.33m Invisible Shield Tempered Glass screen protector for the Samsung Galaxy A3 (2017) is to protect your screen from a fall more than a phone case.

The screen attaches on the phone itself and takes little to no time at all to complete.The screen protector is protected for a lifetime, so if the screen ever breaks, simply register online to get a new one and ship it back to the company.
