Set default storage to SD card on Moto E running Lollipop I have Moto E 2nd gen. and I want to set SD card as my default storage. I googled but nothing useful found. Can someone help me?
There are several ways for doing this:

See this video on YouTube, if your phone can support this method; Or,

See this video to use default file manager to change the storage; Or,

Use file managers like ES File Explorer File Manager. When you try to download a file, it shows you the pop up menu and then you can choose the path for storing the files; Or,

Use Google Chrome Browser. In Chrome, tap the tools drop-down bar in the top right corner → tap Settings → tap Show advanced settings, and enter the file path you want where the file should download.
In other browsers the process is very similar.
