A good investment - the K51S screen protector. If you drop your phone, the display is usually the part that gets damaged in a fall. Unfortunately, such accidents happen very often and quickly. The relief is significant when you have covered the display with a K51S screen protector made of 0.3 mm tempered glass. Because repairs are tedious and expensive! The K51S tempered glass is ultra-thin at just 0.3 mm and does not affect your phone's functions in any way. Invest in the K51S screen protector made of 0.3 mm tempered glass, and you won't have to worry about scratches and dirt on the display anymore.
