If a projector is $99 it's rubbish. And what kind of light source would fit into a cellphone that is bright enough to throw a picture from 2m away from the wall, possibly during day light hours, without eating the battery in 5 mins?
Have you never used a modern-day LED flashlight they can make them tiny with small dials and still make them brighter than the goddamn Sun lol
An flashlight concentrates it's light in a small cone, a projector must spread it over a larger area, while still being brighter than the ambient light if you want to use it as a projector. Take a guess why any good projectors cost more and use expensive hardware, instead of "hurr durr let's just juse a 10 cents flashlight LED!1!!"
There are YouTube channels who review cheap temu tech, and some of them also did cheap projectors, with the expected results.
