I have a Carbonn Phone (model: A18+)
http://www.karbonnmobiles.com/karbonn-A18+-proid-193.html
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.
