security - Can Applications With Root Access Modify Their Own Permissions?
Friday 14th of September 2012
For rooted phones, there are several apps which require root privileges. Knowing this, the user does allow the app to get root. Now, the app would have been installed with a set of x permissions, say INTERNET, LOCATION. Now, on gaining root, is it possible for the app to secretly (or not) give itself extra permissions eg. BLUETOOTH ? I read somewhere that the Apps requiring INTERNET or BLUETOOTH permissions are added to a user group which has access to these device files. So, can a rooted app associate itself to that group and gain the permission ?

Are these software problems or hardware problems?

When I connect to Wi-Fi, it usually works as expected, just with slow data speeds (and it turns out that it's a network issue, not the phone). But occasionally, the phone keeps the Wi-Fi signal, but the Internet connection is completely dropped, which makes any app requiring Internet access useless. When I ask others around me who have phones connected to the same network, I see that they have Internet connection. To resolve the problem, I have to turn Wi-Fi off and back on again. I've also noticed recently that sometimes the phone doesn't connect to the Wi-Fi network even when it's in range. When I see why, the phone says "Failed to obtain IP address." Again, turning Wi-Fi off and back on again fixes the issue. But in both cases, the fix is temporary. Right now, I have the "Always allow scanning" turned OFF, location services are set to high accuracy, and Wi-Fi Power-save mode is enabled. The idea that resetting the Wi-Fi restores lost connections tells me that it's a software issue (i.e. easily fixed) rather than a hardware issue, but I'd like to know what you t
