No—Samsung’s current published guidance says Galaxy phones cannot be downgraded to earlier firmware after updating to the latest software version. Samsung attributes that restriction to enhanced security policies. If the update installed but caused a problem, check for a newer fix or get help with the specific symptom; a factory reset is not a way to restore the previous Android or One UI version.

Can you remove an installed Samsung update?

Samsung India Support states: “Once your device has been updated to the latest software version, you cannot downgrade to a previous firmware version due to enhanced security policies.” The statement is Samsung’s published policy; the exact software available and support options can vary by Galaxy model, region, carrier and version.

Samsung documents Settings and Smart Switch as ways to install available updates, not as methods for uninstalling a successfully installed update. Its Smart Switch recovery instructions address certain failed updates, not a consumer rollback to an older build.

If the update installed but you dislike it or something changed

Check for a newer corrective update

Samsung advises checking for available software updates when a device has problems, since a fix may already be available. On the phone, open Settings > Software update > Download and install. Menu wording can vary by model and software version. You can also connect the phone to Smart Switch on a Windows PC or Mac to see whether an update is offered. Keep the USB connection intact while an update is in progress. Samsung’s India instructions specify at least 20% battery for that workflow; treat this as guidance for that update procedure, not a universal requirement for every device or situation.

Identify the issue and get model-specific help

Before contacting support, note the Galaxy model, current Android and One UI versions, carrier or sales region, and what is going wrong. Update timing and availability can differ by location and carrier, and Samsung notes that menu names and layouts vary. If no corrective update is offered, contact Samsung support for your region and describe the specific symptom.

If the update failed or the phone will not boot

An incomplete installation is a different problem from wanting to remove firmware that installed successfully. For a failed update, Samsung’s troubleshooting guidance includes checking storage, network and USB connection, and using Smart Switch where appropriate. If the phone cannot boot normally after a failed update, Samsung says service may be required to reflash the device. That recovery guidance does not promise that a service center can install a particular older firmware version.

Why a factory reset does not uninstall firmware

A factory reset erases user data and content; it is not a firmware rollback. Samsung describes reset as troubleshooting or recovery and warns users to back up first, but its guidance does not say that resetting restores the prior Android or One UI version. Do not reset solely to return to an earlier update. Consider it only when troubleshooting calls for it and you understand the data-loss risk.

Which route fits your situation?

Your situation What to do What not to expect
The update installed successfully, but you want the old version back Check for a later corrective update or contact Samsung about the issue. Samsung’s cited policy does not support downgrading from the latest firmware.
The update did not finish, or the phone will not boot Use Samsung’s failed-update or emergency-recovery guidance; contact service if it will not boot normally. Recovery instructions are not a supported consumer method for choosing an older build.
You are considering a factory reset Back up first where possible, and reset only if appropriate for the troubleshooting or recovery situation. A reset erases data and is not a firmware rollback.
