The Sunmi P1 4G is a legacy smart payment terminal that has been officially discontinued. While it provided a solid foundation for mobile business transactions, its firmware and hardware specifications are now outdated compared to modern POS standards. Firmware Overview & Versioning
The Sunmi P1 4G runs on Sunmi OS, a deeply customized version of Android 6.0.
Latest Known Version: The most recent documented stable firmware is v1.8.6.
Security Standing: While Sunmi continues to release security bulletins, the P1 4G is no longer prioritized for regular proactive updates, which are now focused on newer models like the P2 and P3 series.
Customization: The firmware supports deep customization via the SUNMI OS platform, allowing businesses to set custom boot animations, wallpapers, and "Kiosk Mode" to lock the device to specific applications. Performance & Capabilities
Hardware Efficiency: It features an ARM Cortex-A7 processor with 1GB RAM and 8GB ROM. By modern standards, this may cause sluggishness when running complex third-party apps, though it remains sufficient for basic transaction processing and 1D/2D QR scanning (0.7s recognition speed).
Connectivity: Supports 4G, Wi-Fi (2.4GHz/5GHz), and global bands (FDD-LTE/GSM/CDMA), ensuring reliable mobile connectivity for outdoor use or deliveries.
Payment Support: The firmware integrates with hardware to support EMV chip, magnetic stripe, and contactless payments (NFC), including Apple Pay and Samsung Pay. Known Firmware Issues & Troubleshooting
Printer Logic Bug: A notable issue in the firmware is related to transactional printing. Unlike newer models, the P1 4G may not return an "out-of-paper" error code immediately; instead, it may wait infinitely until paper is inserted, which can hang some payment applications.
Update Management: Updates are typically pushed via OTA (Over-the-Air) through the Sunmi Partners Platform. Manual flashing is generally discouraged for payment terminals as it can trigger security "tamper" locks, requiring a factory-level key re-injection to restore payment functionality.
App Compatibility: Due to the older Android 6.0 base, many modern apps on the Sunmi App Store may no longer be compatible. Should you update or replace?
If you are still using the P1 4G, it is highly recommended to transition to the Sunmi P2 or P3 series. These newer models run Android 9.0 to 13.0, offer significantly better memory optimization (up to 38.5% more available RAM), and have extended security support cycles.
