If you use Samsung devices you most likely know about Odin, the software that allows you to flash ROMs, radios, and other stuff to your phone. Mobile Odin allows you to do these things on your device without needing a computer.
New in 3.5 is being able to wipe without flashing anything, support for LTE Galaxy S3’s, the newest version of SuperSU, and other small updates. The directions are pretty simple, you need to be root then you just choose your firmware file and you are ready to flash! Here is the list of all supported devices and a direct download link to Google Play store (support the dev — Chainfire).
It’s awesome to have this functionality without needing access to a computer, are you thinking about using this app? Tell us in the comments!
