Ismail M. M. Rahman 1 The product is a terrible one. I bought it for Galaxy Z Flip3 5G. The upper film is like the thin plastic sheets. Is it tempered glass? I doubt. No instruction video is available. So, I applied it following previous experience with other cellphones. However, it was difficult to remove bubbles. The most disappointing point was that the films started to peel off within two days. So, I removed and discarded it. As I have already used it, I cannot claim any refund. But, please be aware of buying it.I was so afraid to see the performance of the cover film. So, I don't dare to use the glass cover at all.NOT Recommended and be aware.
