I recently updated my phone and now none of my apps work. If they do work is really buggy like samsung need to add a rollback option to downgrade or something

Hey there

Welcome to the Forum.

May I please ask, when did you last perform a Wipe Partition Cache on your device?

If you haven't for a while or even ever (many don't know about it) then I would recommend this as a first step.

It won't remove data, just temporary Cache files that may clog up your device over time.

1. Turn off the device.
2. Connect To Computer USBC to USBC (you may also connect to another Samsung mobile via USBC). 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.

@Josephs  You can also Repair apps from the same Recovery Menu and or use the Galaxy Apps Booster from the Good Guardians suite. Ensure also that all your apps are up to date.  If still issues after  these steps would be an idea to start in Safe Mode,sometimes there can  be a conflict with 3rd  party apps or themes and if works fine there  would pinpoint recent apps which may need to be uninstalled.
