In an attempt to give you, our wonderful readers, some of the highest functionality from your Android phones, we here at mobiletweaks has scoured the internet and our own Android smartphones to compile a list of some of the best and most useful secret codes. Some of the codes show very useful information and some allow you access to things that just are not available from the get-go.
Keep in mind that, as always, this information is meant for seasoned and experienced users. If you are not familiar with your phone to the extent that modding and jail breaking your device is something you’ve not considered doing, it’s best to avoid these codes. And as always, we here at mobiletweaks.net are not responsible for any loss of data or hardware damage, so be careful!
Simply enter each of these codes in your phone’s dialer.

This allows a direct file copy of media on the phone, bringing you to a screen and menu that gives access to saved media files such as pictures and music so you can back them up without much issue. Deletion of media files from these menus, however, delete them from any backup they’re included in and make it so that it’s impossible to recover any media lost this way.
