Meta cheating. If they have to spend enough time to make the text scan and read correctly, that will do half the teacher's work. The other solution is the exit exam to pass and graduate - no phones/apps allowed. Iy would be easy to create a screen room inside a school room wherein no phone or WiFi would work. Blocking interdevice WiFi or NFC would need screen boxes. Still, cheating is so creative and rampant that some sort of cages are needed. Put the screen under the wall board to create a few WTF moments when they find they are cut off and get frantic.
