Our verdict
The longest-supported Galaxy M ever, with four OS upgrades and a rare 45W charger on a clean Snapdragon platform.
Pros
- Four OS upgrades plus five years of security — best-in-class for the M-series
- Snapdragon 7 Gen 1 keeps it smooth and avoids the Exynos throttling complaints
- Fast 45W charging instead of the usual 25W M-series cap
Cons
- No IP water-resistance rating
- Only a token 2MP macro alongside the main and ultra-wide

Frequently asked questions
How long will the Galaxy M55 5G get updates?
Samsung commits to four Android OS upgrades (through Android 17) and five years of security patches from its March 2024 launch, so it should stay protected into early 2029 — the longest support of any Galaxy M phone.
Is the Galaxy M55 5G sold in the US?
No. It is an India/Asia/Europe-focused model, so US buyers can only get it through importers or the used market, and it may lack local warranty and band support.
Does the Galaxy M55 5G have fast charging?
Yes. Unlike most M-series phones that cap at 25W, the M55 5G supports 45W wired charging on its 5000mAh battery.
