I bought https://swappa.com/listing/MBS496/view from Swappa. It is Galaxy Nexus (Not just Nexus) used phone. He said it was already rooted. I just got the phone and opened the File Manager and ES File Explorer but I can't find hosts file! This link (http://www.techrepublic.com/article/edit-your-rooted-android-hosts-file-to-block-ad-servers/) says the hosts file will be at system/etc But I get zero results if I search for "hosts". If I search for "etc", the folder is in very strange place. I get zero results if I search for "system". Can it be the case that this phone doesn't have hosts file? The only purpose of buying this cheat-and-rooted phone was to gain access to hosts file to block useless websites like facebook. I need to find and edit that hosts file.. Does anyone know a solution to this?
