Attention: You create your MicroSD partition must be carefully ! The MicroSD have write times life，if you over-write it。

Whether MicroSD or OTG，it's strongly recommended to choose SanDisk(High Stability)。

Other brands may be formatted in EXT3/EXT4 after the end of the fault。

Because of the way the change management program on Android 4.0.x，in the past，a convenient APP-APP2SD has been unable to run。

As Link2SD, although App can be moved to the MicroSD，but to choose the APP is limited(Not all can be move)。

On the other hand，Link2SD only can move the /data/app and /data/dalvik-cache these folders within the APP，but not all App's data。

LetsGoApp is generated using mirroring source on desktop shortcut，when the APP is moving to a MicroSD，the Android system will rest a link icon。

Because it is a linked icon，It takes up very little space(just like as Windows Desktop's Icon 2~5kb)，it is really to storage in the MicroSD to executing。

In addition，the LetsGoApp has more powerful functions is：

1. APP can copy back to Phone ROM through LetsGoApp。

2. LetsGoApp can move the APP to the MicroSD or USB OTG，that You will not use the Phone ROM。

3. Direct to mount 2nd Partition-EXT3 or EXT4。

Through LetsGoApp, the APP still can update/uninstall from Play Store。And just need to click create the link or remove the link，that you can easily move between the ROM and external MicroSD。

You don't need high speed memory card，I just use for general(recommend CLASS 4 above)，and there is no any compatibility problems。

Have been tested MicroSD: Transcend 16G、Kingston 16G、SanDisk 8G.

OTG: Transcend 32G、Kingston 32G、SONY 32G、SanDisk 32G.

Actually！Whether the memory card or OTG recommend to SanDisk and SONY 。

Other brands failure rate is too high，that maybe fault after formatting。

Prerequisite:

1. The Phone/Tablet had been ROOT，and support Memory Card or OTG connect function。

2. Get a MicroSD and then create 2 partitions。The 1st partition is FAT32、the 2nd partition is EXT3/EXT4，and set Avtice at 2nd partition(example:32GB)。

4. A memory card reader for MicroSD(the USB OTG can connect computer)。

P.S: If you choose EXT4 please download MiniTool Partition Wizard Home Edition，because the usage are the same，that I am not otherwise specified!

2. Make sure connected the MicroSD，and executing EaseUS Partition Master to Create Partition :

Creating FAT3 for 1st partition and create as : Primary。As for FAT32 size decide yourself，and then click OK。

The APP - OfficeSuite Pro for example : click vice spinner - ROM，and to show all APP of phone。Find OfficeSuite Pro from the APP's list，and then click it once，the move order will be start to moving to MicroSD。(Does not recommend moving the system built-in program)。

After finished，click vice spinner - SD，there is a APP - OfficeSuite Pro has been copyed into the MicroSD。Why I said "COPY"， because the sources APP - OfficeSuite Pro still has within the phone's Rom(Back to ROM，that you can see it)。So now，I have to delete the sources APP - OfficeSuite Pro of ROM，and then Linking it from MicroSD。Finished above steps，this is a complete process。

For details please see the following my steps :

First of all，click OfficeSuite Pro，and then choose Remove。You can go back to the ROM to make sure，when you remove it has been finished。

Click OfficeSuite Pro again，you will find the remind message just is not the same with before。The before is : " Excute、Remove、Cancel "， but now is : " Install、Remove、Cancel "。

Now! I click " Install " to let the APP of MicroSD to be link with Android。

Then will remind : Link source from ? Of course is SD card，my goal is to save space on my phone， the APP is stored on the SD card to perform。

You will get message to remind you need to quick reboot(Hot Reboot) once，after the linking is completed。If you have many APPs need to link，you can first press Cancel，and then repeat above steps after all the moving was complete，finally to quick reboot it once，it will save time and has efficiency。

After rebooting, LetsGoApp can auto run and list Apps Menu。If you did not mount SD card，relative ! the APP's icon will Gray，because the APP was disappeared。

You can click Setting -> Storage and check.

You can discovery , Your phone's ROM is saved.

You can run App through LetsGoApp.

OfficeSuite Pro is easy to run.

Let APP install to ROM from the MicroSD or USB OTG：

Example，there are some APPs，that I want to use。LetsGoApp can installation directly from SD card copy back to my phone's ROM ,the function can sharing among users。Users can choose the APP of the OTG or MicroSD, and move App to the phone’s ROM.

In other words, LetsGoApp can move and execute APP between OTG/MicroSD and phone’s ROM. There are more choices, You can move APP from phone’s ROM to the other external storage。

Now example for Candy Crush within MicroSD to pressing “Install“。

Click the button “ ROM “，and you can move the APP to the phone’s internal storage " ROM "。

After moved, the system need be reboot once。

Removing MicroSD after reboot, the Candy Crush can be execute from phone's ROM，and there is not any different to download from Play Store。
