Tempered glass is a type of safety glass processed by controlled thermal or chemical treatments that increase about 4x its strength compared with regular glass. Tempered glass screen protectors are efficient against drops and scratches. By design, in case of breakage, tempered glass disintegrates into small pieces and is much less likely to do harm. Tempered glass enhances your usability experience as your fingers glide more smoothly on these screen guards. They prevent excessive fingerprints and oil smudges. You might not even notice they are on the top of your tablet screen. In the First Help Tech store you can find tempered glass for Nokia Tablets to ensure your protection and to secure your device.
