At the concert, some people will hold up iPads to support them. How are they set up?

Some iPads can set their flash as a way to provide support, and some may set an always-on wallpaper on the iPad, or some other patterns. This is also something that many fans will do, but the prerequisite is to fully charge your iPad and keep it with you.

Personally, I don’t recommend it very much, because during this concert, the scene will be quite chaotic. I think it is better to use mobile phone for support. It is easy to carry and easy to operate. If it falls, it's easy to find the iPad, which can easily break. Repairing a pad is still relatively expensive.
