Note: This tutorial is only available for Xiaomi MI 3-Mobile (16GB/64GB)

The following is personally written for me.
First answer the two questions you might ask:

1. Q: What is a partition? What's the use of partitioning?
A: The internal storage of the Android phone has the rules of zoning, removing the part of the system, the remaining space is divided into two parts, part is the data partition (for storage applications, contacts, SMS, call logs, settings and other personal data), the other part is the memory card partition (our photos, music, video, All kinds of files such as game packets are stored here), M 3 Mobile 16GB data partition for the 3.7GB,64GB data partition to 7.9GB, this is the space used to install the application, the space is very tight, when this area is full, the phone will not be able to install any applications, even unable to receive text messages.
The purpose of this post is to allow our phones to install more applications by increasing data partitioning and reducing the way memory cards are partitioned.
2. Q: What is a merge partition?
A: partition data (for storing applications, contacts, text messages, call logs, settings, etc.) with memory card partitions (all kinds of files such as our photos, music, videos, game packets, etc.) are merged into one area, called Merge partition.
Note: The merge partition is unstable and easy to cause the memory card to be lost, so I recommend you to adjust the partition, security and stability.
Important: Please back up all your data!!!
