I need install a game update (1.9GB), but I have have 800 MB or so of internal storage left and I can't run the game on my sd card. I went through my apps and found that the largest one that I don't need was the "package installer" app, which is 800 MB. To my small knowledge, I need that app to install Apk's, but I can do it with other app installers. I haven't experimented with Android system files before, so I have no idea what will happen if uninstall Package Installer.
Edit: This now answered, thanks to advice. I'm just too stupid to find the check mark on my phone.
