Declaration:This teaching supply to Android 4.1 above devices with reference from LetsGoApp's author。

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 Durability)。

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. Through LetsGoApp move the APP to the MicroSD，that you are free to replace the phone and use them。

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

Through LetsGoApp, the APP still can be normal update/uninstall from Play Store。And just need to click create the link or remove the link，that you can easily move between the internal storage space 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)。

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


Get a MicroSD card : Create/Format partitions:

1. I have to reset the MicroSD and create 2 partitions(1st-FAT32、2nd-EXT3/EXT4) to let the phone to mounting it like as internal ROM，so....
download EaseUS Partition Master Free (Pressing Here Get Download)and install it by 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 :
be careful to make sure what the MicroSD ID is yours！do not click to wrong target such as Hard Disk(C: or D:)

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

(The 1st partition-FAT32 could create it bigger to use for personal files to storing such as：photos、movies)

Creating as Primary and EXT3 for the remaining space，and click OK !

Right-click and set Active for 2nd-partition EXT3，and then Apply it :format EXT3 need more time，keep patience waiting! After finished，take the memory card back in the phone。

Install APP - BusyBOX :

P.S : If the storage device is OTG，that you have to installing one more APP - USB OTG Helper by here http://www.letsgoapp.net/?cat=28。

Installing/Executing BusyBOX by Google play Store。




Install LetsGoApp :
1. Installing LetsGoApp by Play Store。https://play.google.com/store/apps/details?id=tseng.lets.go.app

There are four UI controls ：Switching the storage device of target by
1. Main.
2. Vice-Spinner Showing.
3. Menu by menu button.
Finally，all of the above steps results will be presented on the 4. App list。



2. Press the "Menu" key select "Mount SD card 2nd partition" and follow the instructions to reboot again.
If the EXT3 partition can not to be hang it up，temporarily use the APP-LINK2SD mount EXT3 partition



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 tap 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，so 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 be 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，the APP has already to be execute by LetsGoApp and system Apps Menu。If you did not mount SD card，relative ! the APP's icon will grizzle，because the APP was disappeared。







Let APP install to ROM from the MicroSD or USB OTG：
Hypothesis，there are some APPs，that I want to use。LetsGoApp also provides installation directly from SD card storing back to my phone inside the function to facilitate mutual sharing among users。Users can directly 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 by the same way，and there is not any different to download from Play Store。
