I have a Nvidia Shield so I’m running the real Android. I noticed a couple months back I had a couple apps that were perpetually waiting to update. I deleted them, but they returned the next day with the updating bar below them. If I clicked on them, the app wasn’t available. So I had to download and install them, then delete. However, they returned once again. If I go in the settings they are not listed under apps. I guess I can just leave them. I wasn’t using them anyway. Just so very odd.
Can't delete unless you ADB and delete the apps.
