Silly question??

Hi, great looking app. I'm using an s22 SM-S901W android 14. No root of course. I'm wondering if it's possible to use vphonegaga to inject with this app (or other apps like jshook), extract the modified app onto my real device and still be able to install it. A bit more info for you, the app would be a system app signed with samsungs platform sig and I'm not sure if injection of any kind would render the signature invalid or not. I currently have access to system_app context for installing otherwise uninstallable apps sometimes but the platform signature is another story. Any information would be appreciated, thanks again!
