We know that there are several models for each line, despite that, what are the biggest differences between Samsung devices with the abbreviations A and M? Next, check out our guide on the subject and get your questions answered.
1. Definitions of acronyms
Galaxy A
This line was created to replace the Galaxy J, but it did not reduce the number of devices, with their differences between them. The outstanding characteristic in all the devices is to have the large screen, with 6.5 inches of average🇧🇷
The line has devices that serve basic (A10, A20), medium (A30 to A70) and the most demanding users, who work with numerous functions simultaneously (above the A70).
Galaxy M
The “M” line of Samsung smartphones is aimed at online commerce, sold only on the internet. They are more basic models with their large screens. The big difference is the resolutions of the displays compared to the Galaxy A line, but they are not limited to resolution alone.
2. Design
Galaxy A
The design of the Galaxy A line devices are similar in dimensions. If we compare the input models with the high end of the brand, it is not possible to observe as much difference as the dimensions.
Smartphones have a plastic body that reduces the chance of cracking and latching with drops and bumps. They’re not unbeatable, but plastic tends to hold up better. Elegance is left out in favor of a little more resistance and cost savings.
Those who prefer color options, go for the A71 side that is available in: light blue, black, gray and pearl. Most models stay in the basic cycle—dark blue, black, red.
Display details change, but the A01 has its edges on the screen very marked, other input devices are already free of this. On the A line, some models have biometric readers that also make life easier for the user.

Galaxy M
As with the Samsung line A, the differences in size are not easily perceived, with devices similar in terms of physical characteristics.
They all have plastic bodies, which are a little better at resisting fingerprints and light impacts. As for the colors available, they are very limited.🇧🇷 All are equipped with a fingerprint sensor, an advantage over the Galaxy A.
3. Screen
Now the differences become “visible”. Pardon the pun, the change between the screens of the Galaxy A or M line is great, in addition to the individual characteristics of each device within its line.
Galaxy A
The sizes and resolutions of the Galaxy A line displays are in fact far superior to the Galaxy M, when we talk about the high end🇧🇷 If you need good resolution and graphics processing, I recommend the A line, however, the devices have different screen characteristics within the Galaxy A family.
When looking for a device, know that the super AMOLED screens guarantee the reproduction of videos and games with a lot of movement without traces on the screen, in addition to greater fidelity in colors — that is, more vivid.
In addition, the contrast is higher and battery consumption is reduced. These characteristics surpass models with LCD, TFT, PLS, IPS screen.
Super AMOLED is therefore the most suitable for those who like to play games on their cell phones, or watch movies and series. If you only use it for work, accessing e-mails, sending messages, and making calls, the TFT LCD already works.

Galaxy M
The M family models are more economical, even with the large screen, the settings are smaller compared to the Galaxy A, from the A31 model. The M devices have little difference in terms of screen.
The Full HD+ resolution, as well as the super AMOLED screens, favor the details, by having a larger amount of pixels. The greater the amount of pixels on a screen of the same size, the greater the concentration and, consequently, the definition of the image.
4. Processor, performance, storage
In this regard, the dispute between the Samsung Galaxy A and M lines is a little more balanced, and, in some moments, the M line has the advantage.
The greater the device’s RAM memory, the easier it is to work with more advanced applications, or a large number of applications at the same time. Currently, 2 GB does not operate with quality, due to the evolution of the complexity and demand of the applications, it can constantly crash. 3 GB is not good, but you can say that it is “usable”.
The octa-core processors, naturally, are faster in processing, the “tasks” of the cell phone are divided into 8 cores. The speed of each core and the number available make a difference between octa-cores. Understand that between the two lines, the most expensive devices are the fastest.
Storage capacity is simple and not worth buying anything that only comes with 32 GB. The size of applications and files accumulated using the smartphone will fill the device’s memory at a surprising speed.

5. Prices
Now we come to the point to find out the cost-effectiveness of the devices.
Due to the large number of models available, values for the Galaxy A line can vary between BRL 699 and BRL 2,999, depending on the amount of storage and seasonal promotions.
As for line M, the objective is to be more economical and increase the cost/benefit ratio of devices purchased in online stores. The models can be found for values between R$999 and R$1,999 in Brazilian stores.
A positive point is that the two lines bring devices already with 5G technology for more affordable prices and good value for money. So, if you are looking for a cheap smartphone with this feature, the A and M line devices are good choices.
Conclusion
Regardless of whether you are going to buy a Samsung line A or M, the most important thing in all this data is to compare it with your need, as a user.
If your needs are basic, like just using social networks and making calls, models from 3 GB of RAM will be more than enough.
In addition, buying a cell phone with 64 GB of storage may not be ideal, as your device’s memory can fill up quickly. In these cases, a smartphone with at least 128 GB is recommended.
Advanced users such as gamers and streaming viewers should look for screens with higher definition and super AMOLED technology for their advantages.
In the case of RAM memory, models with more than 4 GB, at least, are recommended. If you play a varied amount of heavier games, the more complete devices are better, such as the A70, A71, A80, M31 and M51 models.
Avoid devices with 2 GB of RAM, in all cases. These devices have a greater tendency to brake with use. In this case, it is recommended to wait for a better buying opportunity.
