When sourcing clone phones, you must prioritize the processor (SoC), RAM/ROM capacity, and screen technology. Ensure the supplier provides real hardware specifications rather than 'spoofed' software data; for instance, verify if the chip is a MediaTek (MTK) series or Unisoc. Check the screen resolution (HD vs. FHD) and panel type (LCD vs. AMOLED) to ensure it meets your market's expectations for visual fidelity. Additionally, confirm the battery capacity (mAh) and charging speed to ensure safety and longevity.
