Samsung Galaxy A55

The Galaxy A55 5G was the flagship of Samsung's 2024 Galaxy A series and the model that tried hardest to feel like a more expensive phone. It combines a metal frame, a 4nm Exynos 1480 chip, up to 12GB of RAM, a 32MP selfie camera and a promise of long software support. This page is a review based on the published specifications and manufacturer information. It explains what sets the A55 apart inside Samsung's catalogue, where the hardware is genuinely strong, and where the price tier still shows.

The A55 in Samsung's catalogue

Samsung announced the A55 on 11 March 2024, together with the cheaper Galaxy A35 5G. The UK press release gives 20 March as the start of availability through operators, retailers and the online store, and that is the release date used for this page; other countries began at different times, with Samsung India listing sales from 18 March. We found no US launch price on Samsung's pages, so none is shown. This was the top of the A5x line before the Galaxy A56 arrived, and the page Galaxy A55 vs Galaxy A56 shows what the successor changed. Its cheaper partner is the Galaxy A35, which keeps the screen and battery but uses a slower chip and simpler cameras. Buyers who want something smaller and cheaper today may also look at the Galaxy A26.

A metal frame and a glass sandwich

The most visible change from earlier A5x phones is the build. Samsung's India newsroom says the A55 gets a metal frame for the first time, and the company's marketing describes a flagship-inspired floating camera design with the three lenses in a straight line. Gorilla Glass Victus+ is named on the front and back, and the phone is rated IP67 for dust and for immersion in fresh water up to 1 metre for 30 minutes. The body measures 161.1 x 77.4 x 8.2 mm and weighs 213 g, which is 4 g heavier than the A35 and a little narrower. In its UK announcement Samsung lists four colours, Awesome Ice Blue, Awesome Lemon, Awesome Lilac and Awesome Navy, while the India page names two of them in its overview; availability depends on the country.

The display is a 6.6-inch Super AMOLED panel with a resolution of 1080 x 2340 pixels and an adaptive refresh rate of up to 120Hz. Samsung's regional listing quotes a peak brightness of 1,000 nits in high brightness mode, which is a manufacturer figure for a specific mode. With Vision Booster the screen is meant to stay readable outdoors. The screen is the same size as the A35's, so the step up here is in what sits around it rather than in the panel itself.

Chip, memory and everyday speed

The A55 uses the Exynos 1480, built on a 4nm process according to Samsung's India newsroom. Its CPU runs at up to 2.75 GHz and 2 GHz. Samsung describes upgrades to the NPU, GPU and CPU and a cooling chamber over 70 percent larger than before, meant to hold performance during games or long multitasking sessions. Memory comes as 8GB with 128GB or 256GB of storage, or 12GB with 256GB. The 12GB option is notable, because Samsung's India release highlights the introduction of 12GB RAM on this model, and it gives the phone more headroom for many apps open at once. A microSD card of up to 1 TB can be added through the hybrid slot, which then replaces the second physical SIM; the phone also supports an embedded SIM.

For most people the extra performance shows up in smoother app switching and better frame rates in games compared with the A35, rather than in any visible change to everyday tasks. Samsung supports Wi-Fi 6, Bluetooth 5.3, NFC and USB-C 2.0, and the phone works with Samsung's SmartThings platform. There is no 3.5mm headphone jack.

Cameras that lean on processing

The rear system has a 50MP main camera (f/1.8, with autofocus and optical stabilisation), a 12MP ultra-wide camera (f/2.2) and a 5MP macro camera (f/2.4), with digital zoom up to 10x. The 12MP ultra-wide is a clear step above the A35's 8MP unit. Samsung's emphasis is on enhanced Nightography: the A55 gets an AI-assisted image signal processor that it says delivers low-light images not seen before on the Galaxy A series, along with Night Portrait mode and 12-bit HDR video. Samsung's India newsroom adds a claim of up to 50 percent less noise in dark scenes. These are manufacturer statements, so treat them as direction rather than guarantees.

The front camera is 32MP at f/2.2 and has no autofocus, making it the biggest difference from the 13MP unit in the A35 and a real advantage for video calls and selfies. Video recording goes up to 4K at 30 frames per second, with HD slow motion at 240 fps, and Samsung lists both optical and video digital stabilisation. The 5MP macro camera remains a modest feature rather than a selling point.

Battery, charging and updates

The A55 carries a 5,000 mAh battery with a rated minimum of 4,905 mAh. Samsung's listing gives up to 25 hours of LTE internet use, 24 hours on Wi-Fi, 28 hours of video and 79 hours of audio in test conditions. Charging is 25W through a charger that is sold separately; no wireless charging is listed. The phone launched with Android 14 and One UI 6.1, and Samsung promises up to four OS upgrades and five years of security updates. Samsung Knox Vault makes its Galaxy A debut here, a hardware security area that is separate from the main processor and guards things such as lock-screen credentials and encryption keys.

Day-to-day use

The reason Samsung stresses Nightography, cooling and memory on the A55 is practical: games, evening photos and video calls are the moments when a mid-range phone separates itself from a pricier one. Someone who mostly makes calls, browses and sends messages will notice the differences from the A35 less.

Who it is for

The A55 is for buyers who want the best of Samsung's 2024 mid-range and are prepared to pay for the sturdier frame, the 12MP ultra-wide, the stronger selfie camera and the faster chip. It suits people who take many photos in the evening, make a lot of video calls, or play games, and who want strong security and a long update promise.

Compromises

• 25W wired charging is modest, and the charger is not in the box.
• The 5MP macro camera adds little, and there is no telephoto lens; zoom is digital.
• No wireless charging and no 3.5mm headphone socket.
• At 213 g and 8.2 mm it is a fairly heavy, thick phone for the class.
• The microSD slot is shared with the second physical SIM.
• Specifications and colours vary by market, and no US price was found on Samsung's pages.

In summary, the Galaxy A55 5G is the stronger of the 2024 pair: a metal-framed phone with a 12GB option, a sharper selfie camera and better night processing, held back mainly by 25W charging and a shared card slot.
