So I have a ZTE obsidian (z820) running lollipop 5.1 and I have a 16gb micro SD card in it. There is no way to root this phone that I have found after weeks of searching, and I need to move my apps or at least install new ones to my SD card. Under "default write disk" I have the SD card checked off, but the phone still tries to install the apps to the phone. I've rolled back all the apps I don't use that come stock to their stock versions and disabled them to free up some space and I use the apps I have (not many) but I still get insufficient storage error when I try to install apps. Even internal memory has over 300mb free yet apps only a few megs refuse to install until I delete stuff. Is there anything I can do to remedy this situation??
I've searched around any have no idea what to do.
