Yes, tempered glass for smartphones does provide good protection. It is designed to absorb the impact of a drop or bump, helping to prevent the screen from cracking or shattering. Tempered glass is also scratch-resistant, which helps to keep the screen looking new for longer. Overall, using tempered glass can help to extend the lifespan of a smartphone by providing an extra layer of protection for the screen. **

For the S21 Ultra, tempered glass is better than film for privacy protection. Tempered glass provides better protection against scratches, cracks, and smudges, while also offering privacy features to prevent others from viewing the screen from an angle. I would recommend consulting with a mobile phone accessories store or a trusted online retailer for specific recommendations on the best tempered glass privacy screen protector for the S21 Ultra. **

Yes, a tempered glass screen protector provides better protection for the phone compared to a regular plastic screen protector. Tempered glass is stronger and more durable, making it more resistant to scratches, cracks, and other damage from everyday use. It also provides better impact protection, which can help prevent the phone's screen from shattering if it is dropped or bumped. Overall, a tempered glass screen protector is a worthwhile investment for protecting your phone's screen. **

Tempered glass is designed to be stronger and more durable than regular glass, making it less likely to break under normal circumstances. However, tempered glass can still break if subjected to extreme force or impact. When tempered glass does break, it shatters into small, blunt pieces rather than sharp shards, which reduces the risk of injury. Overall, while tempered glass is more resistant to breaking than regular glass, it is not completely indestructible. **

I cannot accurately determine whether your father is hot-tempered as I do not have personal knowledge of him.

The hammer is both hardened and tempered. Hardening is the process of heating the metal to a high temperature and then rapidly cooling it to increase its hardness. Tempering is the process of reheating the metal to a lower temperature to reduce its brittleness and increase its toughness. This combination of hardening and tempering gives the hammer the right balance of hardness and toughness to withstand repeated impacts without breaking. **
