Software Update
Software update

Software updates are released to update the user interface, enhance security, and remove bugs from your phone. We recommend updating your phone's software whenever it is available.

1 Launch the Settings app and tap on Software update > Download updates manually.
2 If an update is available, you will be given an option to download the update now or later. Tap on DOWNLOAD to continue and once the download is complete, tap on INSTALL NOW to install the update
3 Once the device turns back on, you'll see "Safe Mode" at the bottom of the screen and some apps will be greyed out. Try to see if you can replicate the speed issues in safe mode.

If you have the same problems in Safe Mode, it's more than likely there is a corruption in the operating system. A factory data reset is the best option if you can't get to a Samsung location for further assistance.


To exit Safe mode,  Long press the Power button and select Restart, or manually turn the device off then on again. 

Perform a Factory Data Reset

A factory data reset may help with a blank or frozen screen, apps crashing or freezing, keypad/touchscreen problems, you can perform a hard reset to return it to factory default state.

1 Launch the Settings app and tap on General management > Reset > Factory data reset.
2 You will be given a list of applications and accounts to confirm that you understand the removal of this data from your device. Tap on Reset to continue
3 Confirm your lock screen PIN / Pattern / Password and then tap on DELETE ALL to start the factory data reset.

If you are still experiencing issues after trying the above steps, please register your Note9 for warranty, and/or visit one of our Samsung Service Center for an assessment.
