In OREO you simply press the HOME button twice. The recent/running apps will appear at the bottom of the screen. Use LEFT and RIGHT arrow buttons to select the app. Then, press the HOME button twice and select the app you were on. I forgot to turn on my VPN. I was in the middle of a movie on KODI. I pressed the HOME button twice, selected my VPN, pressed the HOME button twice and selected my paused movie in KODI. Hope this helps all. Moderator please fix my spelling on heading. It wont let me edit title.
No. This is not a fact and it cannot be trusted to work on all Android TV devices that are running Oreo. Consider caveating what you post with specifics.
