[Nexus 5X Q&A, Help & Troubleshooting] roy.garlington:
So my Nexus 5X started behaving abnormally numerous Wi-Fi drops, the size of the internal storage increasing drastically in a short amount of time and other random uncharacteristic behavior. My phone was unrooted with locked bootloader so I read the recovery logs and kernel logs and noticed something was not quite right. My wireless gateway had my Mac address as my IP address and my Mac address. When scanning for open ports on my phone I noticed there were hundreds of open ports in the very high range of ports. I tried to flash the factory image from the Google site and it restored some persistent file systems that are not part of the stock system image. So I rooted my phone to have a look within the root of the system and saw this modified build. Prop file. it seems as though I am running via a virtual machine created inside my Android phone. There are many many system apps installed that are not stock system apps. Any information, knowledge, help on my situation would be greatly appreciated!
