Sometimes we use an Android phone playing kid friendly youtube videos to distract our little boy if he gets upset during changing or such. We try not to, but hey, sometimes you have to be practical.
I have an old S4 running android 5.x. Is there a way to lock it down so it can only play youtube, maybe a couple of kid friendly games I choose, that kind of thing? I don't want him to be able to get into settings, inappropriate youtube content, etc.
