Camera asking for SD Card

IMO, that is NOT a smart move.
the extSDcard should always remain a separate entity period.

if something happens to that phone, all of the data on the SD card is lost... all of it.

Keep the extSDcard as "External Memory", not appended to the phone's internal memory....

Put the SD card back to external, then go into the camera and to Settings, Location, and then set that to extSDcard.

that should resolve your problems.

 

Welcome to Android Forums.

What device and what version of the Android system are you using?

Good Question,

Kindly share more details about your problem with complete device details.

Thanks

But your Android One phone does have an SD doesn't it? Otherwise you probably wouldn't be asking about it. And FWIW I would never buy a phone that doesn't have an SD.

Sure your SD card is actually OK, and not a fake or duff?

 

Sounds like a problem between the camera app and whatever you've done to the storage partitioning. How to solve it, have no idea, suppose you could try a different camera app, see if that works. It could be that the camera app isn't compatible with this feature of Marshmallow, and needs updating.

 

That sounds exactly what the problem is i.e. the stock camera app is hard-coded to use an external microSD card and hasn't been updated to be compatible with the new Android 6.x features/APIs.
