| Problem | Likely Solution | | :--- | :--- | | "No Service" / Emergency calls only | 1. Ensure 4G VoLTE is enabled (Settings > Call settings > VoLTE). 2. Your carrier may have dropped 3G/2G – Koi requires a 4G SIM. | | Can't hear caller | Check volume during call using Up/Down keys. Also verify no protective film covers the earpiece. | | Battery drains fast | Turn off Bluetooth and Hotspot when not in use. Reduce backlight timeout (Settings > Display > Backlight). | | Forgot phone PIN | Enter wrong PIN 3 times → PUK code required. Call your carrier for PUK (SIM locked) or reset device via hardware (see below). | | Phone frozen (unresponsive) | Hard reset: Remove battery → wait 10 seconds → reinsert battery → power on. |
