Can the mobile phone holder be fixed on the bedside or wall?

It’s easy to say. For example, in the dormitory, you only need to find a broken desk lamp (the kind with a big clip), a long wooden board, and two ropes.

Fix the wooden board to the bed rail or backboard with a rope, clamp the wooden board with a desk lamp clip, and replace the lamp with a plastic clip to clamp the mobile phone. You can move the position to adjust the distance. The angle is good, you can even plug in the charger, haha.

There are also professional brackets for hanging LCD monitors on the website. But you need to drill holes in the wall. And the cost is a bit high too.
