TrueCost
Street price ÷ months of safe use remaining — the number that makes cheap short-lived phones expensive, and well-supported ones cheap.
28% cheaper than the $300–600 median ($12.54/mo, dying phones excluded)
Our verdict
The A-series flagship: a metal-framed, glass-backed mid-ranger with the longest support runway of any Galaxy A under $500.
Pros
- Four OS upgrades and five years of security patches keep it current through 2029
- Premium aluminum-and-glass build with IP67 water resistance
- Bright 120Hz Super AMOLED display and 12GB RAM option
Cons
- 25W charging is slow for a 2024 flagship-tier price
- Never officially sold in the US, so support and warranty are awkward stateside

Frequently asked questions
How long will the Galaxy A55 5G get updates?
Samsung guarantees four major Android OS upgrades and five years of security patches from its March 2024 launch, meaning security support runs through roughly March 2029 and it can reach Android 18.
Is the Galaxy A55 5G waterproof?
It carries an IP67 rating, so it survives dust and brief submersion in up to one meter of fresh water for 30 minutes, but it is not built for swimming or saltwater.
Does the Galaxy A55 5G work in the US?
It was not officially launched in the US, so you'll find only imported global units. Core LTE/5G bands work on many US carriers, but band coverage and warranty are not guaranteed.
