How to Fix Chromecast with Google TV Insufficient Storage Space Issues

Who said that it is enough to have tiny storage when you only want to use a few apps on your Chromecast with Google TV? Sure, you only intended to download and install a handful of streaming apps on your new Chromecast device. You might even be thinking you can fit your required apps and still not use up the 8 GB allocated storage that comes with your Chromecast with Google TV.

Sadly, that is not the case here. Even when you only have a number of apps installed and running, Chromecast with Google TV will still run you out of storage sooner than you might think. Aside from the usual apps you download and install, Google TV operating system takes up almost half of your storage allocation.

Furthermore, as you continue to download in-app functions and update the apps, you soon realize that you are facing the “Insufficient Storage” error message. The complete error message when installing a new app or updating an existing one says,

“Insufficient Storage – This device doesn’t have enough space to download “app name”. Consider deleting apps or content you no longer need and try again.”


Your apps may only have a small install space, but the cache data from your streaming sessions will fill up over time. Downloaded data can eat up the bulk of your low storage space.

We can hope to troubleshoot and get a workaround that works in mitigating the storage problem on your Chromecast-enabled streaming player. If we fail to resolve it, you end up not being able to download more content, install additional games, or update your apps.

Use a USB Flash Drive for Added Storage on your Chromecast with Google TV

It is indeed a misfortune for Chromecast with Google TV to provide only 8GB of storage space for its users in this modern time. But, as you are facing a storage issue now, you need to do something to deal with the issue at hand. You can add more external storage space to your Chromecast with Google TV using a USB-C hub.

Since there is only a single port for USB devices, you can use a USB Type C dock or dongle with power splitter and USB ports to increase the storage space of your Chromecast with Google TV media player. The USB C hub must have USB 3.0 speeds or better and a power passthrough. Chromecast with Google TV will reformat the USB-C flash drive that you connect to the hub and use it as additional space for your system storage.

Uninstall Unused Apps on your Chromecast with Google TV

It may not be the best idea, but it also helps to uninstall apps you no longer use, even if there are only a handful of them. You may find this method absurd given that you only have a few selected apps, and the chances of not using all of them are slim. But, it is still an option worth considering given the circumstances.
