The Android hardware test codes are *#0*# and *#*#4636#*#*. The codes might vary through different devices. This method makes it very easy to check if a phone has a required tool or not. This feature is known as an internal testing tool of android.
Learn The Process How to Test Android Hardware
Your android hardware test code is here:
- Open Your phone’s Dialer option
- Enter the code *#0*#; if it not works, enter *#*#4636#*#*.
- After entering the code *#0*#, it will be performed to check your device’s screen display, cameras, sensor, and volumes/power button.
- After entering the code *#*#4636#*#* will help you get the phone’s information like current service carrier, IMEI number, phone number, app usage history, data network connection stats, Wi-Fi status, etc.
Hardware tests are an essential method to make sure the phone is in proper condition. So I recommend that when you buy a used phone, check the phone hardware status once.
