Galaxy M51 vs Galaxy A51 Specs Comparison – Samsung Did What?!


While Samsung Philippines is busy prepping for the local launch of the Galaxy A51, in South Korea, the brewing Galaxy M51 is about to launch very soon. With the Galaxy A series being the best mid-range lineup the company has to offer, it seems like the Galaxy M is about to take that title very soon. Could we finally be seeing the M51 taking the position of the A51 as the best Samsung mid-range phone? Let’s find out.

Do take note that the M51 isn’t official yet which means the specs are not final, however, reliable listings and Samsung’s track record have given us the confidence to do this comparison.

Samsung Galaxy M51 and Galaxy A51 Similarities and Differences

Galaxy A51

Design and Display

If there’s one thing that hasn’t been revealed yet about the Galaxy M51 — it’s the design. But according to rumors, the M51 will look a lot like the Galaxy A51. This means the same patterned hue with “glasstic” material that you see from the images above. However, there will be a triple-camera setup for the M51 but in the same shape and placement as the one’s found on the A51. But there’s a chance that we might see a monocolored glossy back as the M41 was reportedly canceled in favor of M51. With that said, the mid-range phone could see itself using a rear-capacitive fingerprint scanner instead of an in-display type.

One exciting feature fans are looking forward to is the inclusion of an AMOLED display on the M51. And since the should-be OLED supplier failed the quality requirements of Samsung, the chances of providing ink-ish black and saturated colors are slowly disappearing from the view. Instead, the company might use its TFT PLS panel which claims to be better than IPS LCD. We’re not sure about the screen size but it could be around 6.3-inch with FHD+ resolution. Lastly, the notch will be replaced with a pinhole cutout on the top-left corner.

Snapdragon 675(11nm) vs Exynos 9611 (10nm) – for some reason, new mid-range phones sporting old chipsets is becoming a trend. However, pairing them with 8GB RAM is nice to see. Regardless, both chipsets are less exciting than their competitors. While they are more than capable of supporting day-to-day tasks, you can’t expect games to be a walk in the park. And with One UI 2.1, Samsung’s skin requires a bit more power and resources than other Android skins. Furthermore, there could be a significant difference in storage speed. While the A51 is already using UFS 2.0, the M51 could be stuck with eMMC 5.1 that’s mostly found on budget phones.


When it comes to cameras, we suggest taking this with a grain of salt. According to rumors, due to Samsung’s habit of recycling ideas — much like the Galaxy M30s and Galaxy A50s — the same case could apply to the M51. While there’s no Galaxy M50 to compare with in the first place, there is the Galaxy M40. From the start of this comparison, we’ve been comparing the M51 with the M41 in mind. And based on the spec sheet, the two share the same set of features such as the triple-camera setup and chipset.

Going back to the triple cameras, we think Samsung won’t be including the macro lens. However, the main sensor might get upgraded to 48MP but at the expense of EIS. As for the selfie camera, having a 32MP might be asking too much.

For some reason, the Galaxy M40 launched without a headphone jack. Hopefully, that’s not the case with the M51. Other than that, we’re still looking at south-firing speakers for both devices.

Battery and Charging

Samsung Galaxy A51 is still sporting 4000mAh with 15W fast charging even after several iterations. We might see the same thing for the M51, however.


While Samsung Galaxy A51 is yet to be officially introduced by the company in the Philippines, we already know that it’s going to be priced at P17,990. As for the Galaxy M51, we have a good feeling that it will retail for P15,990 if it ever arrives. If you’re wondering how we got to those numbers, the Galaxy M31 recently went official at P13,990. But wait, there’s more. The M31 is cheaper yet it packs Super AMOLED, 6000mAh battery, and 64MP quad-cameras. Sure, you’re still getting a teardrop notch but the phone seems to have better offerings, for the most part, than the A51. So what madness is this? From the surface, it seems this is the “design tax” that you have to deal with if you’re going for A series over M series. If you have a better explanation, we love to hear them in the comment section!
