how to bulk move Android apps to the SD card Currently all my Android apps are on the phone's internal storage, which is quite low @ 8GB.

I've recently install a 32GB SD card into the phone.

I understand that I can go to Android Application Manager > Apps > click on app > click "Move" (to the SD card).

For the several apps I've tried to do this, the "Move" button was grayed out.

Only one app I've tried has had the "Move" button enabled.

Is there any way I can bulk move all Android apps to the SD card?

Android version = 4.4.3
As per Mario's answer:

There is an easier way than manually finding and moving one by one. I'm aware it's no bulk, but it helps.

It helps to find all movable apps, and gets you to the move screen one by one, after you perform the move (manually), also instructing on impacts for each app.
