The Numbers
The number after the letter tells you the tier and year:
- S25 → S Series, launched in 2025
- A55 → A Series, 55 = mid-upper A tier, launched ~2024–2025
- A15 → A Series, 15 = entry-level, launched ~2024–2025
- Z Fold 6 → 6th generation Z Fold (2024)
A Series Number System
- A0x–A1x (e.g., A03, A15): Entry-level, basic specs
- A2x–A3x (e.g., A25, A35): Lower mid-range
- A5x (e.g., A55): Upper mid-range, near-flagship
- A7x–A9x (e.g., A73): Premium mid-range (less common now)
Higher number = better specs (within same generation).
Suffixes and Special Designations
| Suffix | Meaning |
|---|---|
| + (Plus) | Larger screen version (e.g., S25+) |
| Ultra | Top-tier variant with pro features, S Pen |
| FE (Fan Edition) | "Fan Edition" — premium specs at lower cost using prior-gen components |
| 5G | 5G connectivity (most modern Galaxy phones) |
| e | Stripped-down budget variant (rare) |
Example: Decoding "Galaxy S25 Ultra"
- Galaxy = Samsung's main smartphone brand
- S = Flagship S Series
- 25 = 2025 launch year

Example: Decoding "Galaxy A55 5G"
