I installed LBE Privacy on my LG ESteem, and tried it out for for a few days. I uninstalled LBE Privacy Guard a couple days ago, because it kept hassling me to set permissions every time I installed or used a new app. Since I had uninstalled LBE Privacy Guard, my phone has not been able to install new apps properly. Whenever I install a new app, the new app would only work until I reboot my phone. After I reboot my phone, the newly installed apps would fail to launch and give the error message: "the application XXX has stopped unexpectedly. Please try again". That's for every new app I have uninstalled since I had uninstalled LBE Privacy Guard on Wednesday. Another app on my phone, DW Contacts and Phone Dialer Pro, could no longer retain any of my customization settings. DW Contacts popped up an error warning and informed me that the file permission database has some "exception". I immediately knew it's LBE Privacy Guard that had screwed up my phone. I tried re-installing LBE Privacy Guard, and then reboot my phone. As I expected, LBE Privacy Guard has continued to work after multiple reboots. Then I installed a few other apps, but I am still getting the same errors with all other apps. So now LBE Privacy Guard is the ONLY app that has continued to install and work properly after it had screwed up my phone. Then, I googled for information on LBE, and found this: [APP][ROOT] LBE Privacy Guard - Most Powerful privacy protection app for Android - Page 48 - xda-developers Apparently LBE mines user data and is quite shady about doing it, and it also does not like being uninstalled. I suspect LBE made some low-level changes to the permission. It seems to me that everything else (i.e., every new install) has been blocked and denied permission... except LBE itself.
