Putting tempered glass on a phone is good for several reasons:

Protection against drops and scratches: Tempered glass is more durable than regular glass, meaning it can protect your phone's screen from damage caused by drops or scratches.

Improves touch sensitivity: Tempered glass is thinner and smoother to the touch, meaning your phone will feel more comfortable to use.

Easy to clean: Tempered glass is more resistant to smudges and fingerprints, meaning it will be easier to clean and keep clean.

Increases screen lifespan: By protecting your screen from damage, tempered glass can increase the lifespan of your phone and make it last longer.

Improves aesthetics: Putting tempered glass on your phone can also improve the appearance of your device and make it more attractive.

It's important to note that not all tempered glasses are created equal, it's important to choose one of good quality from phonerepairaz.com and from a reputable manufacturer to ensure adequate protection for your device.
