I have my android device rooted, and only one RootTool app (Which is fairly popular and seems trust worthy to me, and which I use to tweak the phone) with root access. And I remember correctly setting the DNS settings to OpenDNS. While sorting out a network issue, Checked My DNS settings , and they were modified.
It turned out that a Video player app caused this change, along with some wierd advertisement in notification bar. After uninstalling that app, I found the market littered with similarly named video player apps, all claimed no root access , but access to device settings.
- Is DNS really an ordinary android setting ? I doesn't appears in settings menu. Can any app without root access this ?
- How dangerous is your address look-up pointed to an unknown server ?
