The Samsung Galaxy A42 5G is a thoroughly decent midrange phone that doesn’t really need to exist.
Taking it at face value, it’s fairly priced at $400 with a big 6.6-inch OLED screen, generous 5,000mAh battery, and a healthy support policy that will see it receiving security updates through the next few years. That’s a pretty good deal.
In the context of Samsung’s Galaxy A lineup, it’s situated between the Galaxy A52 5G and the A32 5G, two very good options in their own price brackets. The $499 A52 5G offers a few more high-end bells and whistles than the A42 5G, like a fast refresh screen and an IP67 waterproof rating. At $279, the more basic A32 5G includes an LCD rather than OLED.
But if you’re shopping for a new device with Verizon, you won’t see either the A52 5G or the A32 5G on the retailer’s shelves (digital or otherwise). Instead, you’ll only find the A42 5G, thanks to one feature it has and the others don’t: mmWave 5G support. Until recently, this was a feature reserved for premium phones, and the A42 5G is one of the least expensive devices that can connect with the network. Verizon in particular has been pushing this super-fast flavor of 5G hard over the past couple of years. Despite its efforts, mmWave is still scarce and highly range-limited, but the carrier is still heavily biasing its stock toward devices that support it.
That’s why the A42 5G exists, at least in the US, but I’m not convinced that’s a good enough reason for anyone besides Verizon.
Samsung A42 5G screen, battery, and performance
The Galaxy A42 5G offers a big 6.6-inch 720p OLED screen. That’s not a lot of resolution stretched across a fairly big panel, and it shows — if you look closely at images you’ll see some pixelation. The screen gets bright enough for indoor use, but I had a hard time seeing it outside even with brightness maxed out. The OLED panel shows nice contrast compared to an LCD (i.e., what you’ll get in a less expensive model like the A32 5G), but otherwise the display is a little underwhelming.
The A42 5G offers an in-display fingerprint sensor for biometric unlocking and it’s one of the better ones I’ve come across in this budget-to-midrange class — it’s responsive and only occasionally fussy. Budget phones often have sensors that are less precise and require additional scans more frequently, and that is a real pain considering how many times we unlock our devices every day.
Battery life is excellent thanks to a large 5,000mAh cell — most days I only drained it to 70 percent by bedtime, but even a day with heavy use that included a Zoom call on cellular data only brought it down around 50 percent. A power user would definitely get a full day and a little extra from it, and with moderate use it can easily be stretched to two days on a charge.
Overall performance from the A42 5G’s Snapdragon 750 processor and 4GB of RAM (there’s a healthy 128GB of storage, too, and it’s expandable via MicroSD) is good for day-to-day tasks. The only slowness I noticed was a little bit of lag starting the camera app, and slight delays using more processing-intensive camera features like portrait mode.
The US version of the A42 5G ships with Android 11. Beyond that, Samsung has guaranteed two additional OS upgrades and four years of security support. In terms of device longevity, that puts it ahead of a lot of the midrange Android competition, which often only sees a couple of years of security support.
Samsung’s current implementation of Android is a little more cluttered than we prefer, and activating it on Verizon’s network means you’ll end up with even more pre-downloaded apps on top of that. It’s a lot. There’s some sort of game featuring a cartoon bear on the phone I’ve been using for the past few weeks, and I do not care for it but I haven’t been able to summon the energy to uninstall it either.
