After leaving the Beta test, if you hope to go back to previous official version you can rollback(downgrade) through Smart Switch.
※ Note
-
If you roll back, your device will be initialized (factory reset). Please back up all data you need before proceeding.
-
Only phone/tablet devices are supported to roll back through Smart Switch, and watch device must be rolled back by visiting the service center.
Please refer to the rollback (downgrade) method from Beta version (Z version) to the previous official version
1. Firstly, install Smart Switch PC version on your PC.
