LG Harmony 4 is a beautifully designed phone. Enclosed with a metal casing, this phone is also packed with shiny features inside. Among the few is a 2GHz Octa-core processor with 3GB RAM.

That’s not everything in this 6.1-inch phone. Besides the good stuff, there’s also some aspect on this phone we think is lacking. Knowing both the good and the bad is important. For details, read our complete LG Harmony 4 review below.

It’s easy to be captivated by this phone’s design immediately. At 156.2 x 74.2 x 8.6mm, LG Harmony 4 is perfectly sized and it’s not too big. Despite the material it uses, the phone only weighs 173g. The highlight of this phone is the material.

It employs metal as the material of its casing. You will get a sturdy phone that feels and looks nice. You can feel the solid weight that gives extra sureness to your palm when holding it. LG Harmony 4 is the kind of phone that gives you the impression of holding an expensive device.

The appearance is not to ignore as well. The back casing comes in a metallic gray color. It likes the phone’s trying to show off that it uses metal. Metal is actually not slippery at all, despite it looks like it is. Additionally, it is better at cooling down the phone and keeping the temperature low.

The front part is black instead of gray. It exudes a more mysterious look with deeper color and is also more fashionable in our opinion. The rounded frame is accentuated with a notch at the top. The bezels are almost non-existent too.

In conclusion, it’s a beautiful-looking phone you can carry with pride. Your friends won’t know if it’s affordable. For buyers emphasizing on looks and build quality, this phone can be a perfect option to consider.

LG Harmony 4 Display

The curved HD+ display on LG Harmony measures 6.1-inch in diameter. This phone has a 19:9.5 aspect ratio and 1560 x 720 pixels in resolution. In short words, we can say this phone is big and sharp, but not amazingly sharp.

Here’s our reason to give such a verdict. For its size, 6.1-inch is perfect. Today’s phone users demand wide, workable space for various activities. In the era where we even do our work via phones, having a large screen is a necessity.

On the other hand, users also need a comfortable screen that doesn’t strain their eyes upon longer use. Having a good quality screen is almost as important as the size.

In this case, LG Harmony 4 falls a bit short of expectation. An HD+ screen is good enough, but it can’t compare to phones with Full HD display in terms of vividness, sharpness, and clarity.

By itself, LG Harmony 4 gives a decent viewing experience. You won’t see any pixelated icons and imperfect images. But the phone can be hard to read when outdoors. At this price point that’s not exactly super cheap, we think LG could afford better quality on this particular model.


LG Harmony 4 Camera

The camera on LG Harmony 4 consists of a 13MP main camera and a 5MP ultra-wide camera. At a glance, it looks like this phone has three cameras on its back cover. However, the third one is an LED flash lamp.

A dual-camera is almost a requirement these days. LG Harmony 4 seems to adhere to this trend. Having two cameras means you get more gears to combine and play around with. It results in overall better photos.

The main camera on LG Harmony 4 also comes with PDAF sensors. The phase detection autofocus means you can capture steady and not-blurry pictures on moving objects. There’s another interesting feature here: You can record a video and take a picture in the middle of the recording.

The result is quite good with all the enhancement features. The wide-angle camera helps to add the depth effect to pictures with intentionally blurred backgrounds.

The camera still performs well under artificial lighting, although you may notice more noises on the results. You can ask help from the night mode to enhance night photos, as well as taking advantage of the LED flash.

The front camera, at 8MP, is able to record 1080p videos as well. Therefore, apart from selfies, you can have a clear zoom call and record short videos for social media. The high-res front camera is another advantage this phone has.

There is 32GB of storage available on this device. Quite a common capacity on the phone, however, we’re rather surprised with the real free space. LG Harmony 4’s system apparently took almost half of it. As a result, you’ll get only 18GB.

This lack of storage space can easily be solved by adding an SD card. You’ll need to spend more money, however. By installing an SD card, you can expand the phone’s storage to up to 200GB. To further preserve internal storage, you can set the camera to automatically save to external storage.


LG Harmony 4 Side

LG Harmony 4 runs on a 2GHz Octa-core processor from MediaTek. The CPU is paired with a 3GB RAM, and it has a GPU integrated with it (IMG PowerVR GE8320.) It’s a pretty solid setup for a phone like LG Harmony 4.

The MediaTek Helio P22 provides support for a dual-camera system this phone has. It’s also what makes 4G LTE possible in this phone. This CPU also promises to be power efficient, despite responsible for maintaining a large HD+ screen.

It’s an all-around CPU that balances performance and price. The key here is “balancing.” So it means you won’t get maximum performance with it. That’s why this particular processor is popular among low to mid-range phones.

At 2GHz of speed, users will be spoiled with the smoothness they’ll experience on everyday apps. This is a phone that won’t disappoint you when editing documents, playing around with photos, and spending hours browsing. Not to mention, it has 3GB of RAM. It means this phone can handle multitasking well.

However, things can get a bit tricky when you try to hit its performance limit. Playing 3D games might not be a good idea if you set the graphic settings to maximum.

Moving into the software, LG Harmony 4 uses Android 10 as its operating system. LG also came up with its own UI. You will like it because the custom UI separates your phone’s look from other Android phones. Even better, the manufacturer also inserted some LG apps on the phone.

Custom apps and UI are known to hinder performance. Luckily, it’s not the case with this phone. We believe it’s because of the adequate CPU and RAM this phone has. Custom UIs tend to feel like bloatware in a super cheap phone, which is not what LG Harmony 4 is.

For sensors, the main thing that stole our attention is the fingerprint sensor. It’s almost a must to have it today. This phone also packs other must-have sensors like an Ambient light sensor and Proximity sensor.

All in all, we liked the performance setup this phone offers buyers. Our LG Harmony 4 review found out that it’s more than decent and remarkably reliable.


LG Harmony 4 allows you to communicate with friends and family using the fast 4G LTE network. Older bands are also supported, such as 3G and 2G. With many phones migrating into 5G right now, sadly it’s not the case yet with this particular model.

But don’t worry. 4G is still the most widely-used fast type of network currently. You can take advantage of the clear call and fast internet, in addition to countrywide coverage.

When you feel like it, turn off the mobile data and use Wi-Fi for even faster browsing. This phone also packs other types of wireless connections starting from the aforementioned Wi-Fi to Bluetooth. You can also use the phone as a mobile hotspot.

Other connectivity features available on this phone include the USB Type-C for PC data transfer. If you’re expecting NFC on this phone, sadly you’ll be disappointed. This is the only thing absent with LG Harmony 4.


LG Harmony 4 runs on a 3,500mAh battery. In our opinion, we saw this as a little bit too small for a phone this big. Particularly the one with more than a 6-inch display. To power that, a phone needs a lot of energy if it wants to be long-lasting.

The phone promises one full day of coverage on a single charge. In our experience, it depends on how someone uses the device. In general, however, 3,500mAh won’t make the phone durable when you’re streaming a movie. It’s best to keep activities light if you plan to keep the phone turned on well until it’s evening.

Is LG Harmony 4 a good phone?

With all those specs above, LG Harmony 4 is sold at a price tag of $119.9. In our opinion, this price justifies the metal body this phone has, the dual-camera, and fingerprint sensor. We also in general don’t have a signing complaint about performance.

But some things should be better. The biggest issue we found in this LG Harmony 4 review is with the battery. It’s too small to carry the demand of the big screen. Furthermore, the internal storage could be bigger too.

LG Harmony 4 suits buyers who like a phone with a cool design and sturdy build quality. We can see it as a suitable phone for people who have an active lifestyle.

LG Harmony 4 Pros

  • Sturdy metal body
  • Fingerprint sensor
  • Dual camera
