I’m seeing a few recommendations to flash a custom ROM.
Wouldn’t that be just great, there’s only one slight problem with that idea …
You mentioned it’s a Samsung device.
Depending on which Samsung device you have, custom ROMS are hard or in some cases impossible to find and the process to install them is more difficult than on some other devices.
Get the process wrong and you’ll brick your phone, so think long and hard before you go down that road.
