I know it sounds strange, but I'm rooted and running a custom ROM on my Galaxy S3. In the ROM, there is a modified version of the Apex Launcher with some custom icons. My phone already automatically updated the launcher before and it removed all of the cool custom icons that were there. So I'd like to prevent that from happening again. I have all of my apps set to automatically update on their own except Apex Launcher. When I rebooted my phone, it began trying to update Apex anyway, probably because restarting reset the settings and caused it to forget that I specifically don't want that app updated. There's an option in Titanium Backup called "Detach from Market" or something to that effect and I tried doing it, but it didn't seem to detach from the Google Play Store. So I'm wondering if there's anything else that I could do to keep this app from updating if possible. I was able to revert the changes because this app has been made into a system app by the dev who made this ROM so when you go into Settings>Applications and try to remove the app, it only says "Uninstall updates" rather than "Uninstall".
