Samsung Galaxy A42 5G review

GSMArena Team, 24 December 2020.

Android 10 and OneUI 2.5

The Galaxy A42 5G boots Android 10, and our review unit arrived with Samsung's latest OneUI 2.5 on top.

The lockscreen is a familiar sight with a couple of shortcuts in the bottom corners and notification icons under a clock. Unfortunately, the Galaxy A42 5G does not support Always-On Display.

Unlocking the Galaxy A42 is best done with the under-screen fingerprint sensor - it works well enough with good speed and accuracy.

If, for whatever reason, you're not thrilled about the A42's fingerprint reader performance, there's also face recognition. It's just camera-based, no 3D face scanning, but it still offers a convenient (if not as secure) way to access your homescreen.

There's little to set the OneUI 2.5 on the A42 apart from other current Samsung phones, regardless of the OneUI version - it all looks familiar.

Gesture navigation is available, and you can choose that in the initial setup process or later on. A system-wide dark mode is par for the course, too.

Edge panels are present on the Galaxy A42. It is a well-known, long-standing feature that gives you quick access to apps, actions, or tools with a single swipe from the side. You can choose which side the handle is located on and adjust its position along the edge of the phone.

Otherwise, the software package is similar to other Samsung phones, with an in-house Gallery app and a file manager. What you won't find on the Galaxy flagships, however, is an FM radio, and there is one here.

There is no Samsung web browser on the Galaxy A42. Google's Chrome is the default app instead.

Performance and benchmarks

The new Snapdragon 750G 5G is powering the Galaxy A42 5G. It is only the second time we meet this SoC, but we already know it is quite a capable piece of hardware. It's a typical mid-range SoC filling the gap between the Snapdragon 765G and the Snapdragon 690. It can also be considered as a successor to the Snapdragon 730G. It's still built on the 8nm node.

The CPU configuration is as follows - 2x Kryo 570 Gold (Cortex-A77 derivative) at 2.2 GHz and 6x Kryo 570 Silver (Cortex-A55 derivative) at 1.8GHz. The chipset also gets a slightly newer Adreno 619 GPU, which is expected to be 10% faster than the Adreno 618 found in the SD730G.

The "G" at the end of the name denotes that the chipset has been optimized for gaming as well supporting Snapdragon Elite Gaming and the fifth-gen AI Engine.

As for memory, the handset starts at 4GB of RAM and 128GB of internal UFS 2.1 storage. You cannot opt for beefier storage, but you and can purchase models with 6GB RAM and even 8GB of RAM.

Let's see this chipset in action.

The Snapdragon 750G 5G offers similar raw CPU performance in single and multi-threaded scenarios as the Snapdragon 765G, and it is better than the Dimensity 800U inside the Realme 7 5G.

The Adreno 619 is an excellent performer in this class and offers up to par raw performance.

The Galaxy A42 5G has a huge advantage over its peers, though - the 720p screen. And when it comes to onscreen performance, the Galaxy A42 is a real champ.

The lower screen resolution probably helped the Galaxy A42 5G beat any other competitor on the AnTuTu 8 test, and it came on top of or mid-range chart.

There are only good things we can say about the Galaxy A42 performance. First, it offers an excellent CPU, GPU, and overall raw performance.

We tried various games, and the phone offers flagship performance in all of them. While the A42 doesn't have an HRR screen, it still offers one of the smoothest and best-quality gaming experiences you can get at that €299 price.

The phone doesn't get hot and doesn't throttle even when running 3D Mark's 20minute WildLife Stress test four times in a row. Nope, the Galaxy A42 is 99.6% stable in all runs. Just wow!

Finally, as you can imagine, the phone handles Android and One UI lag-free and as smooth as it can get.

Yes, the Galaxy A42 5G is a real powerhouse - it offers outstanding gaming performance and a stutter-free Android experience. It's more than we could have wished for at that price, and if it comes at the expense of the higher resolution, well, then perhaps it was worth it.
