I am going to buy an used Nexus 5 today, as the first LG phone, I have no idea how to test the function of the phone. On my Sony Z Ultra, I can use the *#*#7378424#*#* to check all functions of the phone.
So, my question is, is there any way to check all phone functions like vibration, LCD, sound, etc.. using on-phone diagnostics?
Thank you for your time to answer my question, I will meet the sell guy in about 3 hours. Your help is much appreciated.
