If you have a Fire TV devices running Fire OS 7, like the 3rd-gen Fire TV Stick or Fire TV Stick 4K Max, and you sideload many apps, you’ve probably experienced the annoying bug where the icons of some sideloaded apps appear as grayed out missing icons. This bug has been present since at least early 2020 and is a result of the Fire TV home screen launcher not checking all possible locations for an app to store its icon image file. After over 2 years of Fire TV owners living with this bug, Amazon has finally addressed it in a recent update where all sideloaded app icons are now being correctly displayed.
As mentioned, this bug has only affected Fire TV models running Fire OS 7, which include the Fire TV Stick Lite, 3rd-gen Fire TV Stick, Fire TV Stick 4K Max, 2nd-gen Fire TV Cube, and newer Fire TV Smart TVs. Even though it only affects the newer version of Fire OS, the issue is related to the Fire TV home screen launcher, not the operating system, so the fix is being rolled out as a system component update, not an OS update. I can confirm that it has been fixed on the Fire TV Cube and the Fire TV Stick 4K Max, but I assume the other Fire TV models running Fire OS 7 will receive it or are reeving it as well.
You check for and install system component updates the same way you check/install OS updates, which is to either use my Check For Updates shortcut app or by navigating to Settings > My Fire TV > About > Check for updates. As with all Fire TV updates, this one is likely rolling out slowly to select devices, so if you are still having the icon issue and don’t see an update available, all you can do is be patient and wait for your device’s turn to update. It’s a good idea to restart your Fire TV in case the update has been installed already but the launcher just hasn’t tried to refresh your app icons yet.
