Product Name: iPhone 12 Series Dedicated Wi-Fi Antenna Flex Cable

Compatibility: iPhone 12 mini

Replace this dedicated antenna to resolve issues specifically and exclusively related to Wi-Fi connectivity performance, such as:
Weak Wi-Fi Signal Strength: The iPhone consistently shows significantly lower Wi-Fi signal reception compared to other devices in the exact same location.
Slow Wi-Fi Speeds: Download and upload speeds over Wi-Fi are abnormally slow, despite a strong router signal and normal performance on other devices.
Unstable Wi-Fi Connection: The connection frequently drops, requires repeated re-authentication, or experiences severe latency spikes during use.
Limited Wi-Fi Range: The effective range for maintaining a stable Wi-Fi connection is noticeably shorter than expected.
Failure on Specific Wi-Fi Bands: Inability to connect to or poor performance on either the 2.4GHz or 5GHz band, while the other may work normally.
Physical Damage: Visible damage to the dedicated Wi-Fi antenna cable, such as tears, kinks, or a detached connector.

Professional installation is highly recommended.
After installation, you must thoroughly test:
Dual-Band Wi-Fi Test: Connect to both a 2.4GHz and a 5GHz Wi-Fi network. Verify the iPhone can see, connect to, and maintain a strong signal on both bands.
Wi-Fi Speed & Stability Benchmark: Run multiple internet speed tests (e.g., Ookla Speedtest) from the same location. Compare the results to those from another known-good device to confirm performance is normal and consistent.
Signal Range Test: Move to the edge of your Wi-Fi router's typical range and verify the iPhone maintains a usable and stable connection, comparable to other devices.
Peer-to-Peer Wi-Fi Feature Test: Test features that rely on Wi-Fi Direct, such as AirDrop file transfers between Apple devices, to ensure local connectivity is functional.
System Reboot & Verification: Reboot the iPhone. Upon restart, ensure Wi-Fi reconnects automatically and operates normally without any error prompts in Settings.

Quality & Warranty Promise
Every dedicated Wi-Fi antenna is visually inspected for physical integrity and connector condition. It undergoes a basic continuity and impedance test to ensure proper electrical characteristics before shipment.
This product is backed by a 90-day warranty from the delivery date. If the antenna itself fails due to non-human causes (not from installation error, improper adhesion, liquid damage, or physical impact), we provide a free replacement. Please inspect the part upon receipt and contact us with any issues.
