ZTE Obsidian running Android 5.1 doesn't save files to SD card. When I try to update apps through Google Play I can't save the app to the SD card. In settings I chose SD card as the default drive but it still doesn't work. Is there anyway to make the system recognise the SD card? I constantly get insufficient storage space messages.
Later versions of Android do not allow for install to SD card. The cache can be saved here (which you've already enabled the option for) but installing the application directly to the SD card is no longer supported.
