Wi-Fi Config offers extensive technical data about the current connection. This section typically contains highly detailed network parameters. This information is often utilized by network administrators or developers for advanced diagnostics. Finally, Wi-Fi Status presents more digestible information. This includes current signal strength, MAC address, and connection speed. A ping test functionality is also available here to confirm network responsiveness.
Calendar Information (*#*#225#*#* or *#*#CAL#*#*)
The code *#*#225#*#*, or CAL, reveals the Calendar Information menu. This displays a list of all calendars linked to the various Google accounts on the phone. The number of upcoming events for each calendar is also indicated.
While its immediate practical application is limited for most users, it serves as a centralized overview. It can be useful for developers or users managing multiple calendar integrations.
Firebase Cloud Messaging (FCM) Diagnostics (*#*#426#*#*)
The code *#*#426#*#* opens the FCM Diagnostics menu. FCM, or Firebase Cloud Messaging, is a crucial service for push notifications and messaging across Android devices. This menu typically operates on the default Google dialer.
Advanced information can be displayed, revealing extensive technical data. An “events” button may show a log of connections. This is primarily a developer tool for monitoring FCM service status.
Visual Voicemail Configuration (*#*#886266344#*#* or *#*#VVMCONFIG#*#*)
For Visual Voicemail settings, the code *#*#886266344#*#*, or VVMCONFIG, is used. This menu offers options such as synchronizing voicemail. This can be useful if voicemails are not displaying correctly.
A “VVM config override” submenu is also present. This section contains highly sensitive network settings. It should only be accessed by advanced users with specific configuration needs. Incorrect settings may disrupt voicemail services.
Pet Mode (*#*#729#*#* or *#*#PAW#*#*)
An interesting, albeit often deprecated, code is *#*#729#*#*, or PAW. This code activates “Pet Mode.” In older Android versions, an animation of a cat or dog paw would indicate an incoming call.
Upon activation, a visual confirmation of a cat and dog is typically shown. This feature now serves as a nostalgic remnant for many users. Its functionality has been removed in most recent Android iterations.
Cell Broadcast Testing Mode (*#*#2627#*#* or *#*#CMAS#*#*)
The code *#*#2627#*#*, or CMAS, activates Cell Broadcast Testing Mode. Upon entry, a confirmation message indicates its enablement. This mode is related to emergency alerts and public safety messages.
Cell Broadcast messages are distinct from standard text messages. They are used for severe weather warnings or Amber Alerts. Activating this mode allows for testing of these critical communication systems. Disabling is achieved by re-entering the code.
