It would be worthwhile wiping the cache partition if you haven't already after the update

Hi @Foxykene  Ensure all your apps are up to date,could try a Soft Reboot by holding the Volume key simultaneously for around 10 seconds.  Afterwards  optimise Now in Battery and Device Care  and select Memory-Clean Now.  However did you clear the cache partition after the update (as mentioned)as that is recommended and can help with lags.

1. Turn off the device.
2. Connect To Computer or other Device/TV USB , Press and hold the Volume Up key and then press and hold the Power key
3. When the Android logo displays, release both keys.
4. Wait until the Android system recovery menu options appear.
5. Press the Volume down key several times to highlight wipe cache partition.
6. Press Power key to select.
7. Press the Volume down key to highlight yes, them and press the Power key to select.
8. When the wipe cache partition is complete, Reboot system now is highlighted.
9. Press the Power key to restart the device.

Can also repair apps from the same Recovery Menu or/and run the Galaxy Apps Booster from the Good Guardians suite.

@Foxykene also try Safe Mode  > https://www.samsung.com/uk/support/mobile-devices/how-to-start-my-galaxy-device-in-safe-mode/ turns off downloaded apps and themes etc which may highlight an app or theme that's causing conflict. Alternatively long press the power off button and then ling hold on Turn Off to get to Safe Mode. 

A final option would be a back up and factory reset. 

If i can be of any further help please don't hesitate to ask  😎

My Samsung s9 been acting up !! all of a sudden I can't go anywhere in my phone.. app and the screen freeze all the time then the idea came up to me to factory reset my phone I did that and backup some of my data (contacts, messages, call logs) to my sd card. 

I'm done with the factory rest now im trying to take my data back from the SD card to my phone back but for some reason when I enter my Smart Switch to try restore my data this came up 

[ Can't restore your data right now

Please help. I need to know what's wrong and how I can fix it

@Daniel_imonijaye  Sometimes that can be due to a  system error which is fixed in due course.  However could try signing out and in again,  ensure that the right email and password are being used.  do you have 2 step verification set up?  For security reasons the Date and Time needs to be correct. some further information here https://www.samsung.com/latin_en/support/apps-services/why-do-i-get-an-error-when-signing-into-my-sa... 

if issues persist would need to contact Samsung Support https://www.samsung.com/uk/support/contact/
