I think what’s happening is the app is using Android’s account manager to store credentials. These are part of the system and not removed when an app is uninstalled.
If this is what’s happening then you can go to “Passwords & accounts” in settings and find the account to remove. There really shouldn’t be any data left over and you shouldn’t need to clear app data and cache before uninstalling, the system takes good care of that when the app is uninstalled.
You can have any color you want so long as it’s black 😁
You can add the Kingroon KPS3 Pro to the list of printers you might consider.
Bambu labs recently updated their printer firmware to support this feature, but it’s nothing new. If you have a printer that is running or can run klipper, you can enable this. The final piece is a slicer that labels objects in the gcode so they can be excluded. I know both Prusa Slicer and Orca Slicer provide this functionally, there may be others.
Most likely the update will contain the boot.img which would overwrite you’re rooted kernel, assuming a rooted Samsung device still takes updates.
Were all the materials transparent?
