Is it possible to clone a Phone then flash image on other phones?
Short answer. TWRP. Long answer. Team Win Recovery Project, the custom recovery.

Now bad jokes aside, I really wanted to stress how this is the thing you'd like. Using TWRP you can create an image of the entire phone and using it you can restore it to another (or the same) phone. It is very easy to use. You can install it using fastboot/ODIN. It works on non-rooted devices too.

If you don't want to use fastboot/ODIN then you'll need to root the phone and use an app like Flashify to install TWRP, which you can then use to restore the images.

Another option is Titanium Backup. It is effective but I have never used it for the entire phone back up therefore I can't give personal recommendation but I haven't met anyone who talks negative about it yet. It is a well-praised application. Here are the instructions for backing up with Titanium Backup. Please note that Titanium Backup will also require root.

IMPORTANT NOTE: Far as I know there is something that must be taken care of cautiously about Samsungs when flashing/restoring/backing up ROMs that are EFS files. EFS files are the files that include your IMEI number and they are strictly device-specific. Therefore I can't tell for sure but predict that flashing a back-up with EFS files of another phone can be problematic. I would suggest asking about it on Stack Overflow since they'll know better about it.
