Sorry, I should have been clearer - I meant the "power off" button on the widget. But if it's Peel Smart Remote (a right POS app if ever there was one) then I guess that would just turn your TV off.
Force closing the app should get rid of the widget in that case. If the behaviour is new then I guess if you uninstall updates that might ensure it never comes back (make sure auto update is not enabled).
As for compatibility, I guess you have an earlier version than that in the Play Store. Count yourself lucky, because the Play Store app you showed an image of is notorious for adding extra adware lockscreens and crap like that.
That red power off button showing in the the widget turns the Sony AV amp on and off, not the widget itself. That dumb thing was securely stuck on the screen with no way I could find to get it off the screen.. the stuck widget was functional. It has yet to come back and show itself on the home screen.
Curious as to why it did that overnight.
OPPS!, posted too soon, IT IS BACK! and STUCK AGAIN. I will try to nuke it. Unless someone can talk to me about some setting in the app.
Well, not totally stuck as before, swiping the screen makes it fade into the background, but I dont like seeing it stuck on my homepage, it blocks things. I went into app settings, and dont see any options about that showing up on the home page. Plus it always is defaulting to the Sony, not the TV, the usefullness is just not there.
I can not comprehend how such an app gets such glowing reviews.
When I first set this up last week, it did not exhibit this behavior. Do apps just take over your phone making self changes to how they work or autoupdate without your prompting? (actually yes they do autoupdate)
Anyhow, at least it is not stuck anymore, swiping makes it go away.
