Android has several secret helpful codes you can use to navigate around your phone.
Some codes are specific to certain Android models, but you can access others on nearly any Android device.
These codes usually begin with "*#" and are used on mobile phones to access interesting hidden apps and settings.
Here are six codes for your Android device, but it is important to note not all codes may work and some may alter the functionality of your device.
The unique number associated with your smartphone is known as the International Mobile Equipment Identity (IMEI).
This is sometimes asked for when wanting to unlock an Android to use a different network.
Dial *#06# to find your IMEI number, which should just appear on your screen.
Google Play diagnostics
To reveal your Google Play Services information or Firebase Cloud Messaging diagnostics, you can use a code to discover the functionality of your apps.
Type #*#426#*# to access this feature.
If you're unsure if your Wi-Fi or your phone is causing it to lag, you can check how your Wi-Fi is performing.
Input #*#232339#*# to perform a Wi-Fi test on your Android device.
Powering off your device
In a situation when you want to turn off your device, and the power button gets jammed, you can simply type in a code to switch it off.
Type *#*#7594#*#* into your dial pad to power your device off.
Checking data and SMS usage

However, different carriers have different codes.
An AT&T plan you can check your data and SMS usage by typing in *3282#.
