Is Using Your Phone While Charging Safe?

The battery is unarguably one of the most important of a smartphone. I mean, I’m not sure about you but I don’t think I’ve ever seen a smartphone without a battery (tell me if you’ve seen one or use one, though). In the same vein, as important as the battery of a smartphone is, it could also get dangerous.
Take example, the Samsung Galaxy Note 7 “Explosion Gate” saga. Problems with fast charging, battery design, and manufacturing processes were identified as the major reasons why the several units of the phone exploded, particularly while charging the device. This, as well as some myths and misconceptions, have made many smartphone users wonder if they can use their devices simultaneously while charging it without any negative effects on their smartphones and on themselves.

From the screenshot below it implies that my phone support 2 power source which are battery and AC.

What's your opinion on this?
