@Johnnyboy21 Did you wipe the device cache partition after the update? I recommend that you do this after every device update. It wipes out incompatible or outdated cache information which might be incompatible after the update. It does not erase any user data nor applications.
To wipe the device cache partition:
1. Power off your device. 2. Power up while holding down the Volume up key and the Side key until the Samsung logo appears. 3. An Android recovery menu will appear. 4. Use the Volume down key to scroll down to Wipe cache partition. 5. Click the side key to select it. 6. Use the Volume down key to scroll down to Yes. 7. Click the side key to select it. The Cache will be wiped almost instantaneously. 8. Click the side key to select "Reboot system now"
