Is there any method of combining the Android backups from two mobile phones when I move from two single sim phones to a dual sim phone?
I have a Samsung Galaxy S4 running my UK contract SIM, and a ZTE running my PAYG German sim.
I have just purchased a S9+ and I want to use both sims in the one phone. This is not an issue for me.
I have some data stored on the S4 which I do not wish to lose, and some data stored on the ZTE which I also do not wish to lose.
The Android backup show for both phones by name, but I can only use one to migrate my data.
How do I combine the data on two different phones, into a single backup that can be used on my S9.
