Since the old phone ran out of space I got a new one with 4x storage space. Now I'm trying to transfer all the data from the old one to the new one. Alas, data transfer fails because there's not enough space on the old device.
Aye! I am upgrading because the old phone doesn't have any space left, and the data transfer to the new phone fails for the same reason. IDK why the extra space is needed on the phone the data is being transfer from, which is the first question: why does android need that?
Now, the practical one. The suggestion on the screen doesn't really work either: one of the items I'm transferring, the Messages, is causing the transfer to fail even when no other items are selected. Could you suggest a way to transfer all that without any significant storage requirements on the device the data is copied from? Maybe some configuration parameter that would allow the data from the same category to be copies piecemeal in an automatic batch of smaller transfers?
