No Move to SD Card or Move to USB option in android 4.2.2 I have a Carbonn Phone (model: A18+)

Android Version is 4.2.2 

Under Settings -> Storage -> 'Preferred install location' and it has three options for it:


Internal device storage
Phone storage
Let the system decide


there is no option for "External storage device"

but below Preferred install location there is another option: Settings -> Storage -> "Default Write Disk" and it has two options:


Phone storage
SD Card


I have "SD Card" selected here

But I don't have choice to choose SD Card or External storage to install apps and when I install any app from 'play store' that goes to either to phone or to internal storage.
Even after going to the Settings -> Apps ->

I only see 4 tabs

Downloaded | Phone Storage | Running | All

there is no 'SD Card' or 'USB Storage' tab and when i tap any app here it only shows "Move to Phone storage" or "Move to Internal Storage" on 'App Info' Screen.

My question is How can I move or install apps to External SD Card. I have tried many apps like APP2SD or similar ones. But no app gives me to move apps to SD Card. Even I have tried rooting my phone, that also doesn't work.
Move to SD is disabled android 4 onwards. Also App2SD AppMgrIII etc all are useless. I found best solution to this problem after a-week-long search on google I found this very useful new app called FolderMount

Of note, you need to Root your phone. Root It by Easiest means Mobogenie

I tried it on 3 folders (in free version only 3 can be tried) and then immediately bought the pro version; its worth..  just cleared lot of place on my Galaxy Mega 6.3.
