What to do
- Force restart the phone using your model's button combination.
- If touch briefly returns, check settings for a follow-up update or patch.
- If the phone has a physical button, use it to navigate to settings and check for updates.
- Search the manufacturer's support page or community forums for the specific update version and known issues.
- As a last resort, consider restoring from a backup if the option is accessible, since a factory reset can fix corrupted update data.
- Contact the manufacturer's support if the issue is widely reported for that update.
