Nice — here are the commonly used itel / Android secret (USSD / dialer) codes you can try. Important: some codes only show info or test hardware, some can erase data (factory reset). Codes may not work on every itel model (OS/custom operator may block them). Always back up before running reset codes.

How to use: open the Phone app (dialer) → type the code exactly → it runs automatically.

Useful itel / Android secret codes

• *#06# — show IMEI number. (HardReset)

• *#*#4636#*#* — Phone information / battery / usage stats / testing menu. (HardReset)

Safety notes

1. Backup first. Codes like *#*#7780#*#* or brand-specific factory codes will wipe data. (Hard Reset X)

2. Some codes are model- or chipset-specific (MediaTek vs Qualcomm) and may do nothing or open different menus. (Facebook)

3. If a code doesn’t work, your carrier or the phone’s firmware probably blocks it — nothing to worry about.

If you want, tell me your itel model (for example: itel S23, A05s, Vision 5, etc.) and I’ll pick the codes most likely to work on that model and highlight any risky ones.
