OPPO A59 5G Tempered Glass Strong Japanese glass with a 9H surface hardness is used to make tempered glass, which shields it from daily scratches. The curved edge guarantees a polished, rounded surface free of sharp edges and without sacrificing any transparency or clarity. For a cleaner screen, the tempered glass features an oleophobic coating that prevents smudges and fingerprints. It also includes an extra layer that makes it shatter-proof. Because of the 100% bubble-free technology, installing the tempered glass on your own will be simple and problem-free.
