i have the unsupported vwar core3 (H18) and have ordered the next gen Core4 (H19)…
as i want it set up excactly the same way as the Core3 is it possible to make a complete backup of the Core3 to put on the Core4 and so saving a lot of install-time?
No, there is no way to do that, like every phone on Android system you cannot make a backup and a perfect clone… You will have to réinstall your apps and give them passwords and reconfigure them.
