The durability of a smartphone's exterior is influenced by the material used, design, quality of manufacturing, protection, and user handling. To ensure maximum durability, it is essential to choose a phone made with high-quality materials, protect it with a case or screen protector, and handle it with care.

Factors Influencing the Durability of a Smartphone's Exterior
The durability of a smartphone's exterior is influenced by several factors. These include:
Material Used
The material used in constructing the exterior of a smartphone plays a significant role in its durability. Some materials are more durable than others. For example, metal and glass are more durable than plastic.
Design
The design of the smartphone also affects its durability. A well-designed phone will have a sturdy exterior that can withstand falls and other physical impacts. On the other hand, a poorly designed phone may be more susceptible to damage.
Quality of Manufacturing
The quality of manufacturing also plays a role in the durability of a smartphone's exterior. If a phone is made with high-quality materials and assembled with precision, it is likely to be more durable than one that is made with lower-quality materials or assembled carelessly.
Protection
The level of protection provided to the phone also affects its durability. For example, a phone that is regularly covered with a protective case or screen protector is likely to be more durable than one that is not protected.
User Handling
Finally, how a user handles their phone can also affect its durability. Dropping a phone from a height or exposing it to extreme temperatures can reduce its lifespan.
In conclusion, the durability of a smartphone's exterior is influenced by several factors, including the material used, design, quality of manufacturing, protection, and user handling. To ensure maximum durability, it is essential to choose a phone made with high-quality materials, protect it with a case or screen protector, and handle it with care.
