One of the biggest problems with Android is that it doesn't allow to stream YouTube videos when the screen is turned off. It is worth noticing that almost every Android phone comes preloaded with YouTube app.
But, there is a little trick where you can play YouTube videos even when the screen turned off. Check out the below procedure.
Step 1: Download 'Firefox' Browser for Android
To stream YouTube videos even with the phone' screen turned off, you need to download the Mozilla Firefox browser on your Android device.
Step 2: Open 'YouTube' Website
Now, you need to open youtube.com in the downloaded Firefox browser. Make sure you're using the Firefox browser itself because this procedure works only with that particular browser.
Step 3: Request Desktop Site
After entering the site, wait for it to load completely. Now, ask for the desktop site by pressing the three dot menu on the right top side. And, click on the request desktop site.
Step 4: Play Your Music
Next, up you need to play your playlist. Close the browser and lock your device' screen. You will notice that the song will be played in the background.
