** My queries**

1. How to unlock view or see the same option "move to sd" in another model lyf water 7 of android 5.1.1 by modifying the settings through any adb shell fastboot or terminal with or without rooting the mobile.

2. I tried app manager III or app2sd or link2sd apps on unrooted and rooted mobile to do the same but all fails to move the apps. All apps when move to sd option clicked they open take me open same dialogue box window to original settings>app>appinfo option to move apps ( as shown in screenshot above) and there no option of move app to sd

Link2sd when app moved to move to sd it gave following error and link to sd is grayed out and disabled and not working (even on rooted phone)

3. I tried adb shell pm set-install-location 2 in rooted mobile it's changed succesfully but still apps installed through Google Play Store or apkpure do not installs automatically to external sd card they still installing in internal storage not

4. I know all apps are not movable as their app mainfest don't allow I had tried to edit apk editor default prefered install location to external still same app without editing the app is moving to sd card in one mobile and no option of moving not showing option in another mobile with same android 5.1.1 same app same kernal version same.company but different models it means there is some setting lock or change how can we modify or unlock that option .

5. Any more setting I can alter to get the result of moving apps to sd card on my lyf water 7 ls 5504. Any adb shell command. I don't know if its locked in rom or hardware incompatibility then will 3rd party custom rom available in xda may be android 6.03 or android 7.1.1 or android 8,9,10 will allow or have such option and work in the same mobile or not

6. If there is any hardware or rom uncompatibilty or lock by manufacturer or vendor I am worried if I install custom rom of android 6.0.3 marshemellow or android 7.1.1 then will they have such option or not to move app to sd or to format as as internal in both custom rom

Answer 1

Failure [INSTALL_FAILED_INVALID_INSTALL_LOCATION] indicates something is wrong with signature.

If app is moved to MicroSD Card primary partition, Android native app2sd - settings - app - storage - MOVE TO SD CARD - created encrypted container in .android_secure directory which is mounted to /mnt/secure/asec

The same MicroSD Card cannot used in another phone without reformatting, because app2sd get in conflict with existing .android_secure directory which cannot decrypted on other phones.

You are using same MicroSD Card that's why android app2sd (asec) works for only one of both devices.

Reformat or use another MicroSD Card to fix
