The following code works most of the time:
intent = new Intent(Intent.ACTION_VIEW, Uri.parse("content://media/internal/images/media"));
startActivity(intent);
It throws the following exception sometimes (reported by error log from users):
android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.VIEW dat=content://media/internal/images/media }
Stack trace:

I am wondering if some users' Android devices do not have Gallery.

There is no requirement for any Android device to have any exported activity that supports that particular Intent structure (ACTION_VIEW for whatever MIME type is tied to that Uri, plus a content scheme).
Beyond that, there is no single app named "Gallery". Out of ~2 billion devices and ~10,000 device models, there may be hundreds of apps that serve this general role, and a device might not have any such app.
What is a reliable way to open Gallery on Android?
See CATEGORY_APP_GALLERY, and be sure to handle the case where there is no matching activity.
