I've just updated my s8 to November security patch and apk works fine.
At the beginning didn't work, but after these steps it's working again.
1) uninstall using apk found in the op
3) install the apk Google sans
4) reboot again
I've pretty much searched high and low for a simple font app for my note8 and it was almost impossible until i came across the app Afonts by Amjad Al-zakwani. I swear by this app and guarantee you that you will not be disappointed! No root required and you are able to install any font your heart desires, just follow the instructions. I noticed that you can purchase fonts within the app but why when your able to download free ones and install it on the app (a bit silly). And its only for Samsung phones. Good luck
