The 2019 Galaxy A series has more than six models released so far, which guarantees consumer options, but also confuses a lot when it comes to finding the best phone. You’ll get several comparisons of Galaxy A series to other competing phones on the internet, but here we’re going to compare which among the most basic options is worth considering int eh Galaxy A series.

Here are the characteristics, design, and performance of the Galaxy A10, A20, and A30 to decide which one is right for you. So let’s get started.


Design is the only thing that the Galaxy A10, A20, and A30 have more or less in common. The only difference is that the A10 has a shape that most closely resembles the M-line models. The Galaxy A20 has a glossy finish, but without the effects present on the A30.

All have a plastic body, and then we come to another point in the A10: the connector is micro USB, while the other two already have type C USB port.

By the way, to summarize, the A10 still closely resembles the most basic J-line models, including the speaker at the bottom of the rear. A20 and A30 already follow a newer line, maintaining aspects that resemble the models A50 and A70.

On the front, the Galaxy A10 and A20 adopt the Infinity-V display, while the A30 goes for the Infinity-U display, with waterdrop notch for the front camera and minimal edges. In terms of design, only the A10 has different characteristics, giving a more basic face to the device. Each model has three color options.

If you’re just looking for the sleekest, up-to-date design, the A20 already satisfies you as much as the A30, for a smaller value.

Screen, Audio and Features:

As we’ve mentioned before, the A10 has the smallest screen in the series, but still, you get 6.2 inches. The Galaxy A30 and A40 comes with a 6.4-inch display. The panel is LCD on the A10, while A20 and Galaxy A30 feature Super AMOLED display with brighter colors and deeper contrast in addition to deeper black.

The A30 has the advantage of Full HD+ resolution, while the other two only have HD+. For those who want to watch a lot of videos, the most advanced model is the best choice.

In the audio department, all bring the low-quality mono system. The A10 gives a little relief in this regard for even having a low-cost proposal. The A30, on the other hand, is disappointed by its high-pitched sound that forces treble at full volume to give the impression of greater power.

Headphones are basic and the same on all three models. In the end, if you choose the A20, you don’t lose much on audio, and save a little on the A30.

Talking about the software, all models are running the Android 9.0 Pie version, with the OneUI interface. The A10 is again disappointed by not offering even a fingerprint reader, as well as having no compass or gyro. All of them offer the P2 headphone jack. The A30 has more features including the fingerprint sensor.


The difference continues to appear in the hardware. The platform of the A10 and A20 is the same, an Exynos 7884, which may look better than the Moto G7 with Snapdragon 632 in theory, but in practice is below.

The A20 has more RAM, which makes a good difference in everyday use. The A30 has a more powerful platform, the Exynos 7904, and more RAM than the A10 and A20 – 4 GB. And it really is much faster than the A20.

In games, the A30’s superior performance is evident, although it is not even suitable for those who like a heavier title. Overall, the A20 is not bad at all, especially if its use is very basic.


One more aspect which differs the A10 to the other models is the battery. The A20 and A30 carry 4,000mAh of battery, while the A10 has only 3,400mAh battery. OK, it’s for a smaller screen, but it’s insufficient to compensate.

Recharging time on the cheapest model is another drawback, as it takes almost two and a half hours to go from zero to one hundred percent. The A20 and A30 already come with Samsung quick chargers and spend less than two hours in the socket to fully charge.

In this sense, the middle model, once again, is the best for the price charged.


The Galaxy A20 has 13MP+5MP and A30 has 16MP+5MP dual camera sensors at the rear. The A10 offers a single 13MP rear camera. The A20 has an ultra-wide auxiliary lens as an advantage. However, there are real differences in the results.

The A20 only takes advantage of the secondary sensor, which allows you to take pictures with a wider angle of view without having to move away. This lens, however, is quite bad in low light scenarios. And the A30 has the same characteristics in this secondary sensor.

The Galaxy A30 has a loss of focus and median quality on the A10 and A20. Using HDR makes photos less clear but with better exposure balance. In low light, the photos come out dark, but at least they don’t have that much noise.

The A30 already takes slightly better quality photos, but it’s not a big leap compared to the brothers. Low light photos are grainy, but this is true of even very good sensors. The important thing is not to have too many noises.

For selfies, the A10 has a 5MP front camera, the A20 has 8MP sensor and the Galaxy A30 has 16MP sensor. The results are satisfactory on all three models. Obviously, the A30 with higher resolution capture good pictures, but even the A10 takes good pictures, with good detail and controlled exposure.
