What You'll Learn
Plastic Android phones are durable, lightweight, and cost-effective
Plastic Android phones are a great choice for consumers who want a durable, lightweight, and cost-effective device.
Plastic is a highly durable material, able to withstand more abuse than metal or glass before showing signs of wear and tear. It is tough to shatter, scratch, or dent, and its slight flexibility makes it a better shock absorber if dropped, reducing the likelihood of cracks and dents. This makes plastic an excellent choice for those who want a phone that can withstand the rigours of everyday use without easily showing signs of damage.
In addition to its durability, plastic is also a lightweight material. Metal and glass phones can be heavy and brittle, whereas plastic is lighter, making it a more comfortable option for extended periods of use. Its lightweight nature also makes it easier to carry around, ensuring your phone won't weigh you down during your daily activities.
Cost-effectiveness is another advantage of plastic Android phones. Polycarbonate, the type of plastic commonly used in smartphones, is significantly cheaper than metal or glass. This makes plastic phones more affordable for consumers, especially those on a budget. Additionally, the ease of manufacturing plastic phones keeps costs down, as designers have more freedom to work with different shapes without significantly increasing production expenses.
While some may associate plastic phones with a cheap feel, advancements in texturing and ergonomic design have elevated the look and feel of plastic devices. Plastic phones can now offer a premium experience, challenging the notion that metal and glass are the only luxurious options.
With their durability, lightweight construction, and cost-effectiveness, plastic Android phones are a practical and attractive choice for consumers seeking a reliable and affordable smartphone option.

Metal phones are prone to scratches and can hinder radio waves
Metal, plastic, and glass are the three most common materials used to make phones of all sizes. While metal phones are sleek and stylish, they are prone to scratches and can hinder radio waves.
Metal phones, particularly those with a "Space Black" finish, are more susceptible to scratches. This is a significant drawback, as scratches can affect the phone's aesthetic appeal and resale value. Additionally, metal phones can interfere with radio waves, impacting your phone signal. This interference is due to the electrically conductive nature of metals, which can reflect and absorb radio waves, disrupting their transmission.
The issue of signal blockage is not unique to metal phones but is a common problem with various building materials. For example, concrete, plywood, and plaster can all reduce signal strength to varying degrees. Metal roofs and walls are known to cause similar issues, making it challenging to get a reliable reception indoors.
However, it is important to note that not all metals affect cell signals equally. Different metals, such as aluminum, lead, brass, tin, copper, steel, and iron, will have varying degrees of impact on cell signal strength. Additionally, the thickness and composition of the metal play a role in how much it interferes with radio waves. Thicker metals, like multiple layers of aluminum foil, are more likely to cause complete signal blockage.
While metal phones have their drawbacks, they also offer advantages such as a sleek and premium look. Ultimately, when choosing a phone, consumers must consider the trade-offs between different materials and decide which factors are most important to them.

Glass phones are heavy, brittle, and prone to fingerprints
Android phones are typically made of plastic, metal, or glass. While glass phones are often considered to be more premium than their plastic or metal counterparts, they do come with some drawbacks.
One of the main issues with glass phones is that they are prone to fingerprints and smudges. Oils from your fingers can easily be transferred onto the glass surface, leaving behind unsightly marks. Additionally, glass phones tend to be heavier than plastic phones, which can make them more cumbersome to carry around.
The weight of a glass phone can also be a factor in how brittle it is. Glass phones are more prone to shattering or cracking when dropped compared to plastic phones, which can be more flexible and durable. This is especially true for older glass phones, as newer models may benefit from improved manufacturing techniques and materials that increase their durability.
The slipperiness of glass phones is another common issue. The smooth surface of glass can make it difficult to get a secure grip on the device, increasing the chances of it being dropped and potentially damaged. To mitigate this, some manufacturers have started incorporating grip patterns or matte finishes on the back of their glass phones, which can improve grip and also help to disguise fingerprints.
While glass phones have their drawbacks, they also have some advantages. Glass is often chosen by manufacturers because it supports wireless charging and higher data rates like 5G. Additionally, some users prefer the premium look and feel of glass over plastic or metal. Ultimately, the choice between plastic, metal, and glass phones comes down to personal preference, as each material has its own unique set of pros and cons.

Ceramic phones are hard, corrosion-resistant, and lightweight
While many Android phones are made of plastic, metal, or glass, ceramic is another option. Ceramic phones are hard, corrosion-resistant, and lightweight. They are not common in North America, but their popularity is growing with the release of the Galaxy S10+. Ceramic phones, like the Essential Phone and Xiaomi's Mi Mix series, are known for their beauty and durability. They are harder than glass or plastic and lighter than metal.
Ceramic's corrosion resistance is due to its almost complete imperviousness to corrosion. This quality also makes it an excellent insulator, preventing heat transfer. Ceramic is also tough, although it can break under pressure. Its coating can also scratch, so it requires careful handling.
The manufacturing process for ceramic phones is more complex and costly than for plastic phones. Ceramic requires special equipment to mine and manufacture, and the unassembled parts are fragile and prone to shattering. Despite these challenges, ceramic phones offer a premium look and feel that is gaining traction in the market.
In addition to its physical properties, ceramic has electrical benefits. Its insulative properties keep the phone cool, and it does not interfere with radio waves, ensuring strong LTE, Wi-Fi, and Bluetooth signals. Liquid Ceramic, a new type of screen protector, enhances the scratch and shatter resistance of ceramic phones. It fills in microscopic pores and adds an extra layer of invisible glass, improving durability and creating a smoother surface.

Stainless steel phones are viewed as premium
The materials used to make phones have changed over the years, with manufacturers opting for materials like stainless steel and glass to justify the high price tags of premium phones. Stainless steel phones are viewed as premium, and this perception was arguably pioneered by Apple. For six generations, Apple used stainless steel for the iPhone's frame on its most expensive products, and this was eventually followed by Android phones.
Apple's iPhone 4 was the first to be made of stainless steel, and the iPhone X and newer models have continued this trend. Apple's decision to use stainless steel may be due to its association with luxury watches, which are often made of stainless steel. The perception of stainless steel as a premium material is so strong that Android phones that don't feature stainless steel often feature polished aluminum to resemble it.
OnePlus's COO and Head of R&D, Kinder Liu, offers some insight into why Android phones have been slower to adopt stainless steel. One reason is weight. Android devices require larger batteries, which are heavy, and the addition of stainless steel would make the phones even heavier. Another reason is cost; stainless steel is more expensive than other materials, and this would be reflected in the price of the phone.
While stainless steel is viewed as a premium material, it is important to consider whether it creates a premium experience. Some users may prefer plastic phones due to their durability, ease of manufacturing, and ability to transmit radio waves effectively. Additionally, metal phones can be slippery and prone to scratching, which may detract from the user experience.
