Hello Samsung community members.
It's great that many users are trying the Beta program. However, I have seen that some users do not have an idea of what "beta" means and started blaming Samsung for the lag, crashes and issues with the apps and phone.
BETA versions are not a final/stable release version, so you can expect issues with the software and that's why the beta versions are available publicly to get those identified and fixed.
So instead of blaming Samsung please submit a feedback with proper information which will help the developers to identify and fix those issues.
