How to set default download location to ext SD card in Galaxy Grand I already tried to change the download and install location to SD card using ADB but it hasn't worked. All the games and other stuff are being downloaded and installed to phone memory itself.

I don't want to root my phone. I have a 16gb card. Using Samsung Galaxy Grand Duos. Please help.
Without Root access, there is no way possible to change the default install location of apps. You need to have root access in order to make such changes.
