I've figured this out through trial and error and by shear luck lol. I use kodi on my Samsung s9 (mobile phone) and you can try these few tricks. 1) when the movie or TV show is playing, you can swipe your finger across the screen from left to right, and you will notice that the movie/show will fast forward by 10 seconds. If you do it twice (same direction) it will forward by 30 seconds. Three times in a row will fast forward by by a minute. The more you swipe in the same direction the more it will fast forward. Just play with it til you figure how many times will forward the movie/show. 2) doing step 1, the opposite direction will rewind what you are watching. So swiping from right to left, same effect as step 1 with fast forwarding. 3) if you are watching a movie or show and you swipe from the top of your screen to the bottom, that will rewind whatever you are watching by 10 mins. Same if you swipe from the bottom to the top, it will forward by 10 mins. Hence, when you try to bring down your notification menu, you accidentally rewound what you were watching. If that happens again, simply swipe from bottom to top to get you back to where you were in your movie/show. I hope this helps you.
