Need to find the how long my phone has been used?

*#*#4636#*#* is not working in my S7 edge phone.. I don't need the uptime....I want to know whole usage of my phone. I have tried: Yes. I think it was caused by: No


You will not be able to see an entire history of phone usage unless you figure it out as a puzzle. For instance, checking the data usage times for each month and then your Google history on the PC under Mobile Devices. All you are going to get from the phone is uptime with any usage codes or the data you can check within messaging. You could connect to Kies and see if you can find anything within there but I have not tried that.
