In front of me is lgk42 and let me show you how to activate demo mode on the following device. So, first, you need to reach the settings then find and select system and here click on developer options. If you cannot find developer mode right here under system, just take a look at our tutorial on how to unlock developer mode in lgk42 and then smoothly enter now scroll down click on demo mode and smoothly enable it by tapping on the switcher, then, if you'd like to show it as well just mark show demo mode and that's it as you can see from now on, it's also visible. So this is it. That would be all thank you for watching. Please subscribe our channel and leave the thumbs up.
