1. Evaluating the Advantages of Nokia C20
Despite being an affordable smartphone, the Nokia C20 model integrates quite a few advantages such as:
1.1. Compact Design, No Fingerprint Residue
The design is the standout feature of the Nokia C20. With overall dimensions of Length 169.9 mm - Width 77.9 mm - Thickness 8.8 mm and weighing 191 grams, the Nokia C20 is quite comfortable for single-handed use. Along with the back design with a certain level of roughness, it does not easily retain fingerprints, providing comfort for users, especially in tropical countries like Vietnam.
Moreover, with its plastic frame and back, the Nokia C20 is quite durable, almost immune to breaking when in use. Additionally, it also comes with a 3.5mm headphone jack, making it convenient for those who enjoy listening to music through headphones.

1.2. Full Retail Package
Another advantage that we highly appreciate about the Nokia C20 phone is that the retail package of the Nokia C20 phone includes: the phone, charger, cable, headphones, transparent silicone case, SIM ejector pin, user manual.
With all the accessories included, the Nokia C20 seems to deviate from the trend of omitting accessories in the retail package that many smartphones on the market pursue nowadays. This helps C20 users (who are typically people with limited economic conditions) avoid spending extra money to purchase additional accessories for using the phone.
1.3. Decent Quality Large Screen
The Nokia C20 phone is equipped with a 6.5-inch IPS LCD screen, HD+ resolution providing users with a smartphone with a fairly comfortable entertainment space for watching videos or using applications. Even the display of texts and numbers is clearer, suitable for older users.
Of course, users shouldn't compare the screen of this device with mid-range smartphones because at such a ridiculously low price point like that of the Nokia C20, this screen is already of high quality.
1.4. Super Affordable Price
The manufacturer lists the price of the Nokia C20 at 2.49 million Vietnamese dong, however, currently, stores are selling this phone for only 1.5 – 1.9 million dong - an extremely cheap price, and arguably the cheapest for a smartphone on the market today.
At this selling price, it's hard to find any new smartphone on the market today.

2. Critique of Nokia C20's Weaknesses
Alongside many advantages, the Nokia C20 also has certain weaknesses, specifically:
2.1. Basic Tasks Only Configuration
Specifically, the Nokia C20 is equipped with the Spreadtrum SC9863A processor paired with 2GB of RAM and 32GB of internal storage. The device also runs on the Android GO operating system.
With this configuration, the Nokia C20 is only suitable for basic calling and texting needs. For heavier applications like Zalo, Messenger, Facebook, users should consider installing only 1-2 apps to avoid lagging or overload issues. And of course, with the Nokia C20's specifications, we advise against downloading games to play.
2.2. Still Uses Micro USB Charging Port
While most phones have switched to USB Type-C ports, continuing to use a Micro USB port on the Nokia C20 is definitely a drawback of this budget phone from Nokia. Micro USB charging ports are not as common now, so if you happen to forget your charger at home and your phone is running out of battery, it's difficult to borrow a charger from someone else.
2.3. Mediocre Camera Quality
The Nokia C20 is equipped with both front and rear 5MP cameras, which results in mediocre photo quality and even subpar video calling quality.
However, considering the extremely low price of the Nokia C20, users might not have higher expectations.

3. Should You Buy the Nokia C20?
Based on the pros and cons evaluation of the Nokia C20 mentioned above, it can be seen that this is only a suitable choice for those who need a basic phone, such as smartphone beginners or elderly people who only need to make calls.
For users with higher usage needs, it's advisable to consider models in the price range of 4-5 million dong for better options to use in the long run.
