Overview
The most basic Samsung phone in this line, the A02 uses an entry-level MediaTek MT6739W quad-core chipset and a microUSB port rather than USB-C. It's a strictly functional phone for calls, texts, and the lightest of app use — no NFC, modest cameras, and a screen that's fine for basic tasks but nothing more. The 5000 mAh battery is the one genuinely strong spec. Best suited as an extremely low-cost backup phone rather than any kind of daily driver in 2026.
