Samsung Galaxy M55 5G specifications and in-depth review

Samsung Galaxy M55 5G

Manufacturer: Samsung

The Samsung Galaxy M55 5G is a mid-range 5G smartphone running Android 14, built around a 6.7-inch OLED/AMOLED display with a 120Hz refresh rate and a resolution of 1080 x 2400 pixels at 385 ppi. The Always-On Display feature keeps key information visible without fully waking the screen, and the flat panel carries no curved edges or secondary screen. At 7.8 mm thick and 180 g, the device sits on the lighter and slimmer end of the large-screen smartphone range, though it carries no water resistance rating and does not feature branded damage-resistant glass.

Under the hood, the Galaxy M55 5G runs on a Qualcomm Snapdragon 7 Gen 1 chipset built on a 4 nm process, paired with 8 GB of DDR5 RAM and 256 GB of internal storage, with an external memory slot for further expansion. The main camera system combines a 50 MP primary sensor, an 8 MP lens, and a 2 MP sensor, with optical image stabilization and phase-detection autofocus, while the front camera also reaches 50 MP. The 5000 mAh battery supports 45W wired fast charging with a charger included in the box, though wireless charging is not available. Connectivity covers 5G, Wi-Fi 6, Bluetooth 5.2, NFC, GPS, and USB Type-C, rounding out a well-connected feature set for its category.

Pros
  • The 5000 mAh battery paired with 45W wired fast charging and an included charger offers a strong combination of capacity and replenishment speed for daily use
  • A 50 MP main camera with optical image stabilization, phase-detection autofocus, and 4K video recording at 30 fps gives the rear camera system a capable foundation for both photos and video
  • The 50 MP front camera is unusually high-resolution for a mid-range smartphone, making it well suited for selfies and video calls
  • The Snapdragon 7 Gen 1 on a 4 nm process with DDR5 RAM and an AnTuTu score of 584,312 delivers solid processing capability for the category
  • An external memory slot allows storage to be expanded beyond the built-in 256 GB
  • The French Repairability Index score of 8.5 out of 10 indicates the device is designed to be relatively easy to repair
Cons
  • There is no 3.5mm headphone jack, and no high-resolution Bluetooth audio codecs such as aptX, LDAC, or LDAC are supported, limiting wired and high-fidelity wireless audio options
  • The device has no water resistance rating of any kind, leaving it unprotected against moisture or accidental splashes
  • Wireless charging is not supported, restricting charging to wired connections only
  • The USB port is Type-C but runs on USB 2.0, which limits data transfer speeds
  • HDR10, HDR10+, and Dolby Vision are not supported on the display, reducing compatibility with HDR content
  • Direct OS vendor updates are not available, meaning software updates depend on an intermediary rather than coming straight from the OS developer
Who is this for?

The Samsung Galaxy M55 5G is a solid fit for users who prioritize camera versatility and battery endurance in their daily smartphone use. The combination of a 50 MP main camera with optical image stabilization and 4K video recording alongside a matching 50 MP front camera makes it well suited to those who shoot frequently on both sides of the device. The 5000 mAh battery with 45W fast charging serves users who are on their devices for extended periods and need reliable top-ups throughout the day. The Snapdragon 7 Gen 1 chipset with 8 GB of DDR5 RAM and a 120Hz AMOLED display also makes it a practical choice for users who multitask regularly or spend time gaming on mobile.

Who is this NOT for?

Users who frequently use wired headphones will find the absence of a 3.5mm audio jack an immediate inconvenience, and the lack of any high-resolution Bluetooth audio codec support makes high-fidelity wireless audio equally inaccessible. Those who need their device in or around water will find the complete absence of water resistance a meaningful risk, as there is no protection against splashes or submersion. The display's lack of HDR10, HDR10+, or Dolby Vision support makes it a poor fit for users who regularly consume HDR content and expect the display to render it correctly, and the USB 2.0 standard on the Type-C port will frustrate anyone who transfers large files between their phone and a computer regularly.

The device has no water resistance rating, no rugged build, and cannot be folded, positioning it as a standard-form candybar smartphone. Notably, it carries a French Repairability Index score of 8.5 out of 10, indicating a strong performance in terms of ease of repair under that rating framework.

Final Verdict

The Samsung Galaxy M55 5G is a well-rounded mid-range smartphone that makes a strong case for users who want capable imaging and reliable daily endurance in a slim, lightweight body. Its dual 50 MP camera setup with optical image stabilization and 4K video recording stands out as a genuine strength, and the 5000 mAh battery with 45W fast charging keeps the device practical for heavy daily use. The trade-offs — no water resistance, no 3.5mm jack, USB 2.0 speeds, and the absence of HDR display support — are worth weighing depending on individual priorities, but they don't undermine the device's core proposition. For users whose focus falls on photography, endurance, and smooth everyday performance, the Galaxy M55 5G delivers a coherent and capable package.
