While iPhone doesn't have a secret menu like Android, there are hidden tools in Accessibility and Field Test mode.
1. Field Test Mode (Signal Strength)
This shows detailed cellular network data.
- Open the Phone app.
- Dial *3001#12345#* and press Call.
- This opens a dashboard showing signal strength (RSRP) and tower info.
2. Hidden Trackpad
Press and hold the Spacebar on the keyboard. The keys will turn blank, and you can slide your finger around to move the text cursor precisely.
