[XDA Assist] xtechFReak:
Well one of the most important feature root grants is to install app datas on sd card.With games having cache files well over 500 mb these days this has become a must requirement. XDA has several threads on this topic .But as i said "several forums", instead i decided to compile all the most popular methods along with their instruction links! hope it helps!

REQUIREMENTS

Rooted phone

TESTED ON

Redmi Note 4g ( MIUI 7)

MI 3

Motorola g3

(so most probably it will work in yours)

(These methods are tried and tested.but in case something wrong happens, i will not be held responsible)

Method 1

Obb on SD

(xposed required - visit link - http://en.miui.com/thread-184179-1-1.html by Androidfuchs for installation method!)

Obb on sd by Moneytoo is an xposed module which allows users to save their obb files on sd card. i have personally found this method as the best till now.It requires the user nothing but to simply install the module and run! rest all is done by the module itself!

i am using this app to read obb files of Asphalt 8 , Assasin Creeed, Dungeon Hunters and all work fine.the only problem i noticed is the initial increased loading time. But hey! its working...

Method 2

Foldermount

Foldermount by XDA senior member Madmack is an amazing app which allows user to link the internal storage folder to its sd card counterpart.The data is stored on sd card from henceforth.The files will appear in both the source and destination after pinning them. This is normal as the files that you see in your internal sdcard are actually located on your external sdcard. This is how FolderMount "tricks" apps that don't have the ability to save explicitly to the external sdcard. And believe me it works great!

Th eonly drawback being that the free app allows only three folders link plus size restriction. But if you love it you can buy the permiuim version from inside the app!

Download the app from google playstore! or use this link http://xdaforums.com/attachment.php?attachmentid=3472016&d=1442128178

Method 3

Link2Sd

I actualy found this method quite cumbersome.But i found few friends who swear by this method.So keeping their faith intact, Link2sd is actually a pretty good app, after the initial installation stages which are lets say "difficult?" The app requires you to create a partition on Sdcard which is used by Link2sd to link the games and cache files.

Most users use AParted app for creating such partitions.

You can download these apps directly from playstore
