If you feel you have done necessary basic checks perhaps Check for further Software Updates: Samsung acknowledged the lock screen bug and other issues with One UI 7 and has been rolling out hotfix patches to resolve major problems, including a recovery patch for the lock screen delivered via the Galaxy Store. Go to Settings > Software update > Download and install to check if a new update is available that addresses this specific bug.
Optimize Device Care: Ensure your device performance is optimized by closing background apps, managing battery usage, and scanning for issues. Navigate to Settings > Battery and device care > Optimize now.
Factory Data Reset (Last Resort): If all else fails and your phone remains consistently unusable, a factory data reset might be necessary. Crucially, back up all your data beforehand, as this will erase all personal information and restore the device to its factory settings. You can do this by going to Settings > General management > Reset > Factory data reset.
Samsung Support & Service: If the issue persists even after a factory reset, or if you prefer professional assistance, consider contacting Samsung Support or visiting an authorized service center for inspection and repair, as the issue might be hardware-related in some cases.
