It's been 1.5yrs since the launch of the Galaxy S8 and till date, there are no custom ROMS available for this particular device. I know, flashing would be like going against the rules but at least Samsung should give an option for people who are fed up of the software being laggy or stuttery sometimes. Really hoping Samsung to release the firmware numbers in order for developers to start working on custom ROMS for the Galaxy S8.
We do apologize for the inconvenience caused. For the device hanging issue please provide logs/video within 15 minutes of issue occurrence by registering this feedback in Error Section (Samsung Members App -> Feedback -> Questions/Errors -> Create -> Error reports). Samsung recommend downloading the update from FOTA or smart switch and does not provide any custom ROM for the device.
