Over the last several weeks my roku randomly shuts down apps I'm using. It's not a timer. It's not my internet I have 500 mbp. I would think it's just me but all my friends who stream locally are having the same issue. It's discouraging to watch programs an to have to constantly go back into the app that was just shut down. It's not just one app it happens with, it all apps. Can anyone lead me tell me how to solve this? Maybe going to a firestick would be a better option.
If you are powering your Roku by plugging into the USB port on the TV, try powering from house power via the USB power adapter that came with the Roku*.
The ports on many televisions only supply 0.5 amp or less, which is not enough to power a Roku reliably. It may appear to start up okay, but when it runs into something that requires more power than the tv's USB port can provide, something's got to give. Frequently this results in shutting down the stream you are viewing and exiting back to the Roku home screen.
If this is a new problem, possibly an update to either the Roku operating software or to some channel app software is using a little more power than in the past. If you were just barely scraping by before, this might push you over the edge.
*If your Roku didn't come with an adapter, or if you don't have a Roku adapter handy, any other USB power adapter you have from another device should work as long as the fine print on it says it outputs at least 1 amp.
I am experiencing the same issue with a 40” Roku TV I purchased several days ago. Apps shut down when watching shows and the TV returns to the Home Screen. This happened with the Spectrum App and the Prime Video App so far. Other than this issue, which is serious if it persists, I like the TV.
