But I think Google Play background service could be checking for the modification of the system files as well.
Regarding checking for rooted device is currently easy as doing 'su' to root but this can be prevented. Rooting device is much easier than replacing the whole firmware. So, the application could be looking for clues whatever the device isn't rooted and that should be good enough for this moment.Īnother thing is that there won't be many users of custom firmware (I think so), but many with rooted one. While it is possible for the App Developer and Google to secure software from this as much as they can, there's problem with the device root access and custom firmware (which is customized Android without root).
