Smartphones change quickly. Every year, new devices arrive with larger displays, faster processors, advanced cameras, and features that once seemed impossible. However, not every phone needs to be the newest or most powerful model to be useful.
The LG K20 Plus represents a different approach to smartphones. Designed as an affordable device, it focused on essential features such as a practical display, removable battery, expandable storage, fingerprint security, and reliable everyday connectivity. It was aimed at people who wanted a straightforward smartphone without paying flagship-level prices.
For anyone considering an older budget phone, using one as a backup device, or simply learning more about this model, it is important to understand both its strengths and its limitations. The technology that once made it competitive now belongs to an earlier generation of mobile devices. Still, some of its features remain interesting even today.
This complete guide explores the design, display, performance, camera system, battery, software, storage, connectivity, security features, advantages, disadvantages, and overall value of the LG K20 Plus.
1. An Overview of the LG K20 Plus
The LG K20 Plus was introduced as part of LG’s budget-friendly K series. Its purpose was simple: provide the core smartphone experience at a more accessible price.
The device included a 5.3-inch HD display, a 13-megapixel rear camera, a 5-megapixel front camera, a removable battery, Android Nougat, and expandable storage. LG also included a rear-mounted fingerprint scanner, which was a useful feature for an affordable phone during its era.
At the time, these features gave users a balanced package for calling, messaging, browsing, social media, photography, and entertainment.
Today, however, the phone should be viewed differently. Modern smartphones have significantly improved in areas such as processing power, camera technology, software support, display quality, charging speed, and network capabilities.
That does not mean the device has become completely useless. Instead, its value now depends heavily on how someone plans to use it.
The most suitable uses today may include:
- Basic calling and texting
- Light web browsing
- Simple applications
- Music playback
- Offline media
- Emergency backup use
- Secondary phone use
- Learning about older Android devices
For demanding users, however, newer smartphones will offer a much better experience.
2. Design and Build Quality
The LG K20 Plus has a traditional smartphone design that reflects the style of its generation. Unlike many modern devices with extremely thin bezels and large edge-to-edge screens, this phone has more visible borders around the display.
Its design is simple rather than flashy.
The phone measures approximately 148.6 x 75.2 x 7.9 mm, making it relatively compact compared with many modern smartphones. Its lighter weight also helps make it comfortable to hold for long periods.
A Comfortable Size for Everyday Use
One noticeable advantage of the device is its manageable size.
Modern phones have become increasingly large. Some people enjoy big screens, especially for videos and gaming, but others find them difficult to use with one hand.
The smaller form factor makes this device easier to carry in a pocket and more comfortable for users who prefer compact phones.
You can think of it like comparing a small notebook with a large desktop planner. The larger option may provide more space, but the smaller one is often easier to carry and use quickly.
Physical Features
The design includes several practical elements, including:
- Rear fingerprint scanner
- Physical ports and buttons
- 3.5mm headphone jack
- Expandable storage support
- Removable battery design
The removable battery is especially interesting because this feature has become rare in modern smartphones.
Instead of permanently sealing the battery inside the device, users can potentially replace it when necessary. This can make long-term maintenance easier, particularly if the original battery begins losing capacity.
3. Display Quality and Viewing Experience
The smartphone features a 5.3-inch HD IPS display with a resolution of 720 x 1280 pixels. LG promoted the device with an HD IPS In-Cell Touch display, designed to provide a practical viewing experience for everyday activities.
What Does the Display Offer?
For normal activities, the screen is suitable for:
- Reading articles
- Browsing websites
- Using social media
- Watching standard videos
- Messaging
- Checking emails
- Viewing photos
The display technology provides decent viewing angles and color reproduction for a budget device from its generation.
However, users should not expect the same experience offered by modern OLED or high-resolution smartphone screens.
Resolution in Modern Use
The 720p resolution was common among affordable phones when this device was released. Today, many budget smartphones provide Full HD or higher resolutions.
As a result, users may notice that text and images do not appear as sharp as they do on newer devices.
Still, screen quality depends partly on expectations.
If you are using the device for simple tasks such as messaging or making calls, the display can remain perfectly functional. But if you regularly watch high-resolution video or enjoy detailed photography, a newer phone will provide a significantly better visual experience.
4. Performance and Everyday Speed
Performance is one of the most important areas to consider when discussing an older smartphone.
The device uses the Qualcomm Snapdragon 425 processor, combined with 2GB of RAM. This hardware was designed for entry-level smartphone tasks rather than intensive workloads.
What Can It Handle?
The phone can manage lighter activities such as:
- Phone calls
- Text messages
- Basic web browsing
- Music streaming
- Simple social media use
- Lightweight applications
For these tasks, the experience can be acceptable when the device is maintained properly and unnecessary background applications are limited.
Where Does Performance Become Difficult?
Modern mobile applications have become more demanding over time.
Many current apps require more memory, processing power, and newer software versions. Because of this, users may experience:
- Slow application loading
- Delays while switching between apps
- Reduced multitasking ability
- Lag during browsing
- Difficulty running newer applications
- Poor performance in demanding games
The 2GB RAM configuration is particularly limiting by modern standards.
Think of RAM as the size of a desk. A large desk allows you to spread out many documents and work on several things at once. A small desk forces you to put things away before bringing out something new.
Similarly, limited memory makes multitasking more difficult.
Gaming Performance
The phone was never designed to be a gaming powerhouse.
Simple and older mobile games may run reasonably well, but demanding modern titles are likely to struggle.
Users should not expect smooth performance from:
- High-end 3D games
- Advanced graphics settings
- Heavy multiplayer games
- Long gaming sessions with demanding applications
For casual games, however, the device may still provide basic entertainment.
5. Camera Features and Photography Experience
The phone includes a 13-megapixel rear camera with autofocus and a 5-megapixel front camera. The rear camera supports features such as HDR and LED flash, while video recording can reach Full HD resolution under supported conditions.
Rear Camera Performance
The 13-megapixel main camera is best suited for everyday photography.
In good lighting conditions, it can capture useful images for:
- Casual photos
- Outdoor scenes
- Documents
- Social media sharing
- Family moments
Lighting plays an important role.
Like many older budget cameras, the image quality can decrease significantly in darker environments.
Low-Light Photography
Low-light photography is one of the areas where modern smartphones have improved dramatically.
Newer phones often use:
- Larger sensors
- Advanced image processing
- Night modes
- Multiple cameras
- Artificial intelligence enhancement
- Optical stabilization
The LG K20 Plus does not offer the same level of technology.
As a result, nighttime images may appear softer, darker, or noisier.
Front Camera
The 5-megapixel front camera was designed primarily for selfies and video communication.
It can handle basic self-portraits and video calling, but users should not expect the advanced portrait effects, detailed sensors, or AI improvements found on modern devices.
For casual use, however, it serves its purpose.
6. Battery Life and the Removable Battery Advantage
Battery design is one of the most interesting aspects of this phone.
Many versions include a removable battery, with capacities varying by model and carrier version. LG’s official T-Mobile listing highlights a 2,700mAh removable battery, while some variants used a slightly different capacity.
Why Is a Removable Battery Important?
Modern smartphones usually use sealed battery designs.
These designs can help manufacturers create slimmer devices, but replacing the battery often requires professional repair.
A removable battery provides several potential advantages.
Users may be able to:
- Replace an aging battery more easily

Because the device is now several years old, battery condition is especially important.
A used phone with an original battery may not perform as well as it did when new. Anyone buying a second-hand unit should carefully check the battery health and consider replacing the battery if necessary.
7. Storage and Expandable Memory
Storage can make or break the experience of using a smartphone.
The LG K20 Plus was available with different storage configurations depending on the model and market. Some versions included 16GB of internal storage, while others offered 32GB. The device also supports expandable storage through a dedicated microSD card slot.
Why Expandable Storage Matters
Expandable storage is another feature that has become less common in some smartphone categories.
A microSD card can provide additional space for:
- Photos
- Videos
- Music
- Documents
- Offline files
This can be especially useful on a device with limited internal storage.
The Challenge of Modern Apps
Modern applications are much larger than older apps.
Operating systems also require more storage space, leaving less room for users.
A 16GB model can feel particularly limited today. Even the 32GB version may require careful storage management.
Users can improve the experience by:
- Removing unused applications
- Clearing unnecessary files
- Moving supported media to a memory card
- Using cloud storage where possible
- Keeping large videos off internal storage
8. Software and Android Experience
The phone launched with Android 7.0 Nougat, which was a modern version of Android during its release period.
At the time, Android Nougat offered a capable mobile experience with improved notifications, multitasking features, and performance enhancements.
However, software age is now one of the biggest concerns.
Why Older Software Can Be a Problem
Technology moves quickly.
Modern applications are often designed for newer Android versions. Over time, some apps may stop supporting older operating systems.
This can affect:

- Social media apps
- Communication tools
For a backup phone or offline device, this may not be a major concern.
For a primary smartphone, however, software support should be considered carefully.
Security Considerations
Using older software can increase security concerns because older devices may no longer receive regular updates.
If you plan to use an older smartphone, it is wise to:
- Install apps only from trusted sources
- Avoid suspicious links
- Use strong passwords
- Keep important information protected
- Avoid storing highly sensitive data unnecessarily
The phone can still perform basic tasks, but users should understand the limitations of older software.
9. Connectivity and Communication Features
The device supports the communication technologies expected from a smartphone of its generation, including cellular connectivity, Wi-Fi, Bluetooth, GPS, and other standard features. Different versions were released for different carriers, so network compatibility can vary depending on the exact model.
4G and Network Compatibility
One important point is that not every version supports the same network bands.
Before purchasing a used unit, buyers should always check:
- Exact model number
- Carrier compatibility
- Supported network bands
- Whether the device is unlocked
- Compatibility with their local network
This is particularly important when purchasing an older phone online.
Other Connectivity Features
The phone includes useful features such as:
- Wi-Fi
- Bluetooth
- GPS
- 3.5mm headphone connection
- MicroUSB charging
The headphone jack remains useful for people who prefer traditional wired headphones.
However, the MicroUSB port is now outdated compared with the USB-C standard used by most modern smartphones.
10. Fingerprint Security and Everyday Convenience
The rear-mounted fingerprint scanner is one of the more useful features of the device.
Instead of entering a PIN or password every time, users can unlock the phone using a registered fingerprint.
Why Fingerprint Security Matters
Biometric security adds convenience to daily smartphone use.
You can quickly access the phone without repeatedly typing a password.
The rear placement may also feel natural because your finger can rest near the scanner while holding the device.
Modern smartphones now offer more advanced biometric systems, but a fingerprint scanner remains a practical security feature.
For everyday use, this feature adds convenience without making the phone more complicated.
