I have been struggling to update my apps on my google play store on my galaxy S9. It would go up to 99% done and just wont move anywhere from there.
I've tried different secured wifi areas, turned off my powersaving mode to make my cpu faster but nothing seems to work. I have not tried to factory reset my phone but at this point I am running out of options.
Is the google play store app updated?
Have you tried opening system settings/apps / Google play store /storage and clear the cache files?
An easy way to see if you are running the most recent play store version. Open the play store app/ settings/ scroll down to play store version and tap on it. It will check if your running the latest version and notify you with a pop-up.
If you installed a recent monthly security patch and the issue started soon after the standard wipe the system cache partition trouble shooting step might be worth a try.
