TV keeps exiting app and going back to home screen
I am having this exact issue when trying to stream Netflix. It bumps back to the Home Screen after a few minutes. I have a Roku TV which is only 4 years old.
I don’t see where in settings to adjust how long it can auto play; however I didn’t change any settings so it shouldn’t be doing this in the first place.
It sounds as if stray infrared signals are being detected, or emitted from the remote.
Or somebody else using a different but compatible remote and messing with you. Let's rule that out for our purposes and assume it's an actual mechanical issue.
Roku TV remotes, which are made by third parties -- Phillips in your case -- use infrared controls. If there is dust or other foreign substances inside the remote causing the contacts to engage, you can get stray button presses without actually pressing a button. Try blowing out the remote with compressed air if possible.
If stray button actions are happening, does removing the batteries stop it? And if so, does putting the batteries back in cause them to resume? If so, then either dust/dirt is causing contacts to close unexpectedly, or there is a fault in the remote. Contact Phillips if that's the case. Roku didn't build the device, simply provided the software in the device Phillips built. Or take the batteries out and use a Roku Voice Remote to control the TV. (I know, a solution where you spend $20 is not an ideal solution.)
If removing the batteries does not impact the actions -- that is, they happen anyway -- then stray infrared signals could be the problem. If the problems are limited to certain times of the day, then outside light (which does include infrared) could be the cause. A perfect storm of circumstances that result in stray light signals (invisible infrared light) causing it. Close the drapes. Does that make a difference?
The other thing could be simply a defective TV. If that's the case, again you would contact the retailer or Phillips directly.
